Plumbing Plans for Permit - I Can Draw Them for You

Just about every city and town I know of requires plumbing plans for a permit. The only two that come to mind that do not are Bar Harbor, Maine, and Thornton, New Hampshire. The plumbing plans are often called riser diagrams or isometric drawings. These drawings telegraph to the plumbing inspector that you know the exact size pipe to drain and vent each fixture.

I've been a master plumber since 1981 and I love to draw plumbing riser diagrams. Allow me to draw your plumbing plans for your permit.

Tim Carter has been a master plumber since 1981. He knows all about plumbing fixture schedules.

I produce color-coded drawings to make it easy for you to understand what pipes go where. You can call me to place your order or if you have questions before placing an order. CALL me at 603-470-0508. I'm in New Hampshire and I turn my phone off at night. If you get my voicemail, I could also be down in my submarine at the lake.

What Other Plumbing Plans Do You Draw?

I also can draw plumbing plans for gas lines and water lines. Gas line plans are very intensive because the black-iron pipe size is very critical to ensure enough gas gets to each appliance. The same is true for water lines if you have a home with three, or more, bedrooms. You must have adequate water pressure for all fixtures when many people are using water at the same time.

Why are Plumbing Plans Important?

Plumbing plans are important because fixtures must have the correct pipe size to drain away the waste. The plans also show the correct vent-pipe connections and the vent-pipe size.

Fixtures that don't have the correct venting can cause sewer gas and vermin to enter your home. Vermin are nasty creatures that lurk in pitch-black sewer pipes. They're far worse than sandworms you might encounter on Jupiter.

How Fast Can Plumbing Plans be Drawn?

The normal time for me to draw plumbing plans is about five days. I do offer expedited turnaround times for either 24-hour service or 48-hour service.

What about Building Drain Layout Plans?

If you're going to install your own plumbing on the job and have never installed the horizontal pipes under a slab or in a crawlspace, you might want to invest in a building drain layout. These pipes must be installed in a very special way to minimize clogs and to get the waste out of the house as soon as possible. I draw the pipes as if I was going to install them myself on your job. CALL me if you have questions about your order: 603-470-0508

Do You Offer Phone Coaching for DIY Plumbers?

Yes, you and I can talk on the phone in 15-minute chunks of time. I helped Zoe discover how to install all the plumbing pipes in her new home. She was 28 years old and building in rural New Mexico. She got all she needed from me in just three calls!

A Riser Diagram for Plumbing, Water or Gas Lines

A riser diagram is a handy tool that allows you to see what size pipes you must install for a drain, waste, and vent (DWV) system in commercial or residential plumbing.

I've been a master plumber since 1981 and have drawn hundreds and hundreds of riser diagrams for architects, builders, and homeowners. I love drawing them. CALL ME NOW - I want to help you get your permit: 603-470-0508

Why is a Riser Diagram Required?

Most code officials who issue building and plumbing permits require a riser diagram to prevent you from getting sick in your home. Sewer gas and vermin can enter your home with ease if your system is not designed and installed correctly. A properly drawn riser diagram will ensure the plumbing system functions perfectly for years. In addition, the traps under fixtures will not be siphoned dry because you didn't vent a fixture correctly.

Tim Carter has been a master plumber since 1981 and can draw your residential riser diagram.

Back in the late 1800s when the medical profession associated microscopic bacteria and pathogens with bad health, physicians realized that exposure to human waste was causing deadly diseases like cholera. It wasn't long before plumbers became as important, or possibly more important than physicians.

Plumbers were the guardians of public health and were held in high esteem all those years ago. This is the basis for why plumbers make so much money. Most humans value their health above all else. They're willing to pay top dollar to ensure they don't get sick. What's more, most humans have no interest in dealing with pipes that have feces flowing through them!

What Does a Riser Diagram Show?

A riser diagram for drain, waste, and vent lines shows the sizes of the pipes and how they're interconnected as part of an entire system.  Pipes must be sized correctly to prevent clogs, ensure solid waste is not left behind, and to ensure plenty of air enters the system to prevent trap siphoning.

Are All the Fittings Shown on the Diagram?

Some mechanical engineers will show all of the exact fittings that are required. This is rarely done on residential riser diagrams because you have to be on the job site to see what framing obstacles are in your way. Once again, the purpose of the diagram is to show the plumbing department you understand what sized pipes go where.

Do You Know Anyone Who Offers Phone Coaching Plumbing Help?

Yes, I offer phone coaching and plumbing help. Several years ago I helped Zoe. She built her own home in rural New Mexico. She was 28 years old and installed all the pipes herself. It only required three 15-minute phone calls.

Home Depot Quartz Countertop Story

Home Depot Quartz Countertop | That shiny spot on the countertop is NOT water. It's silicone caulk. Copyright 2023 Tim Carter ALL RIGHTS RESERVED

Home Depot Quartz Countertop Story

Two days ago, February 24, 2023, I found myself re-installing three sinks for a young woman Kathy and I know from our church. She had new countertops installed in her kitchen and two bathrooms by Home Depot.

The day before I was at her home as the countertop contract workers from Home Depot were finishing up the installation. The lead installer had out a tablet and took some photos of the tops and then asked the young woman to sign the tablet "so I can get paid from Home Depot". That's exactly what he said - I heard it.

It's important to realize this young woman is an expert in contract language. All she does all day long is read the fine print in contracts to protect her company.

She said, "I'd like to inspect the countertops if you don't mind." She went to all three rooms and looked at them. It was a pressure situation as the installer was hovering over her the entire time. Even I felt the stress.

I was on the first floor and they went up to the second-floor bathroom. Evidently, the installers smeared some silicone caulk on the quartz tops leaving a dark area. She pointed this out and the installer said it was water.

How it could be water is a mystery since the SINK WAS DISCONNECTED! What did he do, get water from the toilet bowl/tank????

The young woman then asked him a few questions about the warranty and he responded that it does include labor and material and is for a year.

Trust Can Be Dangerous

She then signed the tablet.

Here's my Samsung tablet. You can pinch it all day long to get it to do what you want. Copyright 2023 Tim Carter ALL RIGHTS RESERVED

After the installer was gone, she got an email from Home Depot thanking her for signing the Release of Lien. Realize I didn't read the email. I'm just sharing hearsay.

But it gets worse, much worse. When I arrived the next day to reconnect the sinks, the young woman shared more details about signing the tablet.

She said, "He actually duplicated my signature. I signed one block and he re-produced it on two documents on the tablet. He didn't make those two available for me to read. It's illegal."

I arrived the next day to install the sinks and that wet area on the second-floor countertop was still there. It was NOT WATER. I'm convinced it was smeared silicone caulk that was used to adhere the quartz backsplashes to the wall.

Let's go back to the tablet. Do you know how you can enlarge parts of what you see on a screen by putting your thumb and index finger on the screen and spreading them apart?

The installer had done this so just the signature area of the document was showing on the screen and you couldn't read any of the text above without scrolling. That, in my opinion, is very unethical.

The young woman was signing an important legal document and she was not aware of it.

All in the heat of the moment.

How to Avoid Unethical Behavior

I KNOW you've been in a similar situation at some point in your life.

I know I have!

How could this have been avoided? What's the teaching moment?

When she went to Home Depot to look at the countertops and to set up the purchase, she SHOULD HAVE ASKED to speak with the Installed-Sales manager.

She should have said, "Can you provide me with a copy, either digital or paper, of EVERY DOCUMENT I'll be required to sign INCLUDING any documents that the installer may have me sign when he completes the work?"

You then READ those documents BEFORE you place your order. You keep the documents so at the time a tablet is placed in front of you you can see if there's an EXTRA document you're being asked to sign that you've never seen before.

If you're NOT COMFORTABLE signing any documents at the time the installation is finished, DO NOT SIGN THEM. The installer is not going to rip out the work. Ask the installer to call the Installed-Sales manager at Home Depot/Lowe's/or the company you placed the order.

Tell that person you MAY sign them AFTER you've had a chance to read them. You don't want to surrender rights or say you're happy with the installation until you can look closely at the work after the contractor has left.

Yes, I know you might DAMAGE the work after he leaves, but allow the contractor to take as MANY PHOTOS as she/he desires to protect her/his interest.

You should do this with ANY contractor/salesperson you deal with. It could be a replacement window/door company, a roofing contractor, or a kitchen/bath cabinet dealer.

For the love of God, STOP trusting people and STOP being played.

Artificial Intelligence and Home Improvement

Artificial Intelligence and Home Improvement - This is what greets you when you go to the artificial intelligence ChatGPT website. Note the absence of any human face or photo. Copyright 2023 Tim Carter

Artificial Intelligence and Home Improvement - Humans 1 AI Zero

I’m celebrating my thirtieth year of doing my best to protect you against home improvement scams, not-so-good products, and anything that’s a threat to you when it comes to building, remodeling, or maintaining your home. I’ve stood up to billion-dollar corporations to prevail on your behalf. But now I’m here to alert you of something far more sinister. I perceive it to be a grave threat to you, your relatives, your neighbors, and your co-workers.

This danger is much worse than the smarmiest high-pressure salesman that might ever cross your threshold. Have you been paying attention to the rise of artificial intelligence (AI)? In the past few months, it’s made a fairly big splash and it must be on your radar. AI, in my opinion, is going to make it extremely hard for you to discover the information you need to make smart and informed decisions when you're about to spend money on your home.

Years ago I was one of the founding charter members of a secret Internet mastermind group. Most of the people in the group were brilliant and collectively we helped each other’s online business grow and thrive. Several of us are still in touch and recently one of them assisted me in demonstrating the scary power of artificial intelligence.

You may remember a column I wrote just weeks ago about painting rusty metal. My friend asked the ChatGPT AI software to write a similar column and include an anecdote about my oldest daughter in the 500-word column.

Surveyed Nearly 1,000 Homeowners

I then decided to survey the subscribers of my weekly newsletter. I asked them to read the AI column and then read the one I had written. It’s important to realize I didn’t share with them who authored the two columns. I have a link at the end of this column to a page where you can read both columns.

When I asked my subscribers how authoritative each column was, the results shocked me. Just over 51 percent considered the ChatGPT column very authoritative. Slightly more than 54 percent thought that my column was very authoritative. When asked which column they trusted more, just over 75 percent voted for mine. Remember, at the time they made the above choices they had no idea who wrote either column.

In the last question of the survey, I asked, “If you discovered one of the two articles above was written by software that copied parts of other online articles not knowing what was good or bad information within the articles it copied, what would be your reaction?

Just over 77 percent of the respondents said they’d be upset and unhappy. Fourteen percent didn’t care as they just wanted to know how to paint rusty metal. The remainder of the respondents typed in their own responses. If I had to summarize all of these into one, here’s what it would be, "Aw! I'm shocked and my mouth is hanging open! They're both great articles, but No. 1 does seem more scientific and well-researched. No. 2 is folksy. I'm still shocked!”

Go here to see who wrote the more scientific and well-researched one and who wrote the folksy one.

Why is AI a Threat?

The AI software has gone out onto the Internet and scraped content from millions of websites like a bulldozer collects and tumbles dirt in front of its blade. The software then studies the content for patterns. The deeply troubling thing is that the software can’t think like you and me. It has no idea if some of the content it scraped is filled with errors.

Perhaps the best comparison to content created by AI software is to think about what a genius kindergartener might write. But then realize how much life experience that 5-year-old has. How much confidence would you put in an AI column you were reading just before signing a contract for a $75,000 home improvement project?

Remember how ChatGPT was asked to create a story about my oldest daughter and me? It did write the short anecdote but it was all a lie. The story it created never happened. How will you be able to tell in the future what is the truth and what is a lie when the AI software starts to create false stories to ensnare you?

Quite a few of my subscribers, once I revealed they had been faked out by a computer, said that they’d invest the time online to get more opinions about what they should do when faced with a problem. Do you see the flaw here moving down the timeline? What percentage of the content in the future will have been created by AI software? How will you know what was created by a human like me who has forty years of field experience vs. a computer that’s just trying to guess what the correct answer is?

Deep-Fake AI Videos Will Trick You

This AI plague is not just overtaking the written word. It’s also being used to create fake videos. The deep fakes possible today are so realistic that they fool many professionals. You can upload photos of people you know, or home improvement celebrities, and the AI software will create videos you think the actual person recorded. It can even get their voice right. Realize this is happening in 2023.

What is going to happen by 2025, or 2030? I think your best bet will be to try to find and stick close to humans like me that have decades of experience working in the homes of people like you. I guess within fifty years robots will be able to say they did that, but we’re not there just yet. Go here to read the ChatGPT content.

Column 1497

ChatGPT vs Tim Carter

ChatGPT vs Tim Carter a Real Human

Below are two columns. One was written by the artificial intelligence software ChatGPT. The other was written by me, Tim Carter. I was an award-winning builder before I started my syndicated newspaper column Ask the Builder.

After reading each one, think about how authoritative each one is. Are you SURE you'd be able to tell in the future a column created by a non-human?

Start reading:

Column #1:

Painting rusty metal and steel is a common task for homeowners and professionals alike. The process of painting rusty metal requires careful preparation to ensure a long-lasting, attractive finish. In addition to improving the appearance of metal surfaces, painting can also help prevent gas line explosions.

Before painting, it is important to remove any loose or flaking rust from the surface of the metal. This can be done using a wire brush or sandpaper. After the rust has been removed, the surface should be cleaned thoroughly to remove any dirt, oil, or other contaminants that could interfere with the adhesion of the paint. A degreaser or a mixture of water and vinegar can be used to clean the surface.

Once the surface has been thoroughly cleaned, it is time to apply a rust-inhibiting primer. This type of primer contains zinc or another metal that will help prevent rust from forming in the future. The primer should be applied in thin, even coats using a brush or sprayer. It is important to allow the primer to dry completely before applying the topcoat.

When choosing a topcoat for painting rusty metal, it is important to select a paint that is specifically designed for use on metal surfaces. Some common types of paint for metal include alkyd enamels, epoxy enamels, and urethane enamels. These types of paint provide excellent durability and resistance to corrosion and abrasion. The topcoat should be applied in the same manner as the primer, with thin, even coats.

In addition to improving the appearance of metal surfaces, painting can also help prevent gas line explosions. Rust can weaken metal pipes and increase the risk of gas leaks. When metal pipes are painted, the paint creates a barrier that helps to protect the metal from rust and corrosion. This can help to prolong the life of the pipes and reduce the risk of gas leaks and explosions.

An interesting anecdote about painting metal is the story of Tim Carter and his daughter Meghan. Tim is a renowned home improvement expert and the founder of AsktheBuilder.com. One day, while working on a home improvement project, Tim's daughter Meghan noticed that the gas pipes in their basement were rusted and in poor condition. Tim knew that painting the pipes would help to prevent gas leaks and explosions, so he took the time to clean and paint the pipes. Meghan was fascinated by the process and helped her father every step of the way.

Today, Meghan is a successful contractor and home improvement expert in her own right. She often shares the story of her father's project and the importance of painting rusty metal to prevent gas line explosions. Meghan's passion for home improvement and safety has inspired many others to take an active role in maintaining and improving their homes.

In conclusion, painting rusty metal and steel is a simple but important task that can improve the appearance and safety of metal surfaces. By removing rust, applying a rust-inhibiting primer, and selecting the appropriate topcoat, you can create a long-lasting, attractive finish that will help prevent gas line explosions. Whether you're a professional contractor or a do-it-yourself homeowner, taking the time to paint rusty metal can have a significant impact on the appearance and safety of your home.

Column #2:

Did you see in the recent news the catastrophic gas explosion that killed nine people on the island of Jersey in the English Channel? It’s early in the investigation and the experts may not ever be able to pinpoint the cause, but I have my own idea based on something that happened to me two years ago.

I was hired by a small condominium association to do a thorough inspection of some outdoor covered decks that had leak issues and wood rot problems. This building was located just a mile or so from the Atlantic Ocean in New Hampshire. The flats on Jersey island were subject to the same marine environment.

My inspection started at the uppermost deck and I worked my way down to the ground-floor deck. When I was underneath the deck in a passageway that led to a basement door, I saw black iron gas lines that extended from the outdoor meters into the basement. These are connected to the water heaters and furnaces.

The iron pipes weren’t black. They were a crusty brown as they were completely coated in rust. I immediately informed the president of the condo association that these pipes must be painted with a special rust primer and then two coats of finish paint. I instructed her to make sure she read the instructions on the label of the special metal rust primer to prepare the pipes so the primer adhered well.

I was reminded of a quote from the captain of the Norwegian Dawn cruise ship. I had attended a talk of his five years ago while on a short cruise and he said, “The sea EATS iron and men.” If you remember some of your high school chemistry you know this to be true. Saltwater is extremely corrosive to unprotected steel and iron.

You may or may not know this but I’ve been a master plumber since 1981. I’ve installed miles of black iron gas lines in my lifetime. I’ve hand-threaded each and every pipe with cutting dies. You may have never thought about the threaded pipe, but where the grooves are the pipe wall thickness has been cut away and reduced to create the threads.

This means that the strength of the pipe is much less in these grooves. If rust has been working on the pipe eating away at the iron, then if something bumps the pipe or it becomes stressed or bent by accident, the metal at the base of the grooves can crack just like you bending a thin pop-top tab on a soft drink can. Gas now starts flowing from the pipe like air from a blown-up balloon.

You don’t need to live near the ocean for this to happen. Normal rain or humidity in the air will cause rust to form and grow on unprotected iron or steel. Your house has all sorts of structural steel elements that are rusting. Many ignore this rust at their peril.

What about your deck joist hangers? I know they were galvanized when they were installed, but has that zinc coating worn off and do you see rust?

What about the nails that attach the deck joist hangers and other structural connectors to the wood? Is the copper in the treated lumber leaching out with each rain event causing rust and corrosion?

What about those cheap electroplated roofing nails the roofer used to install your shingles? I’ve seen new roofing nails transform into rusty fasteners in as little as five to seven years. The best roofing nails are ones that are double-dipped hot galvanized. Period.

What about any steel support posts in your basement or crawlspace? Do you see rust on these? What happens if the rust eats through the post and someone bumps into it?

What about rust on any horizontal steel I-beams in your basement or crawlspace? Are you ignoring it? If so, you’re making a sad mistake.

The good news for you is that painting rusty black iron pipe or all the things I listed above is absolutely a simple DIY job. Most of the high-quality rust primers and special rust finish paints are available in spray cans should you not like to use a brush.

I recorded a video about five years ago showing the difference between two top rust-paint brands. The test panels in the ASTM scratch test were like night and day. I urge you to watch this video so you purchase a paint that will last for many years, even in a marine environment.

# # #

The first column was done by ChatGPT. The story about my daughter Meghan was a LIE. It never happened. The second column was written by me and you can see it here on my website.

In my opinion, you're DOOMED. Within a few years, thousands of websites will use ChatGPT or similar AI software to create MILLIONS of home improvement columns that probably will contain errors and fake stories to FOOL you.

Lead in Ceramic Coffee Mugs

Lead in Ceramic Coffee Mugs - You Could be Killing Yourself Slowly

Do you have ceramic mugs as you see in the photo above?

Did you know the silica glaze and the pigments used in them often contain lead?

Did you know how little lead it makes to make you sick? I copied this from the past column I wrote about lead paint in the late 1990s:

"It takes very little lead to cause severe physical problems. Lead seeks out and attacks the central nervous system.

When health officials measure lead in a person's body, they deal in increments of micrograms (one microgram equals one-millionth of a gram). To put this in perspective consider a packet of artificial sweetener found on the average restaurant table. A single packet usually contains about one gram or 1,000,000 micrograms of artificial sweetener. Open a packet and pour the sweetener onto a colored piece of paper. Look at how small 1,000,000 micrograms actually is!

Imagine if you created a similar pile of pure lead dust. Since lead weighs far more than artificial sweetener, the pile would actually be smaller. If an adult male receives an acute intake of just 5,000 micrograms of lead - just 1/200th of this small pile of dust, he will most likely die in a very short period of time. It takes far less lead in a child or an adult to cause irreversible physical defects such as coordination problems, learning disabilities, seizures, kidney, and heart and reproductive problems."

Watch this video to see the CORRECT way to test for lead in your ceramic coffee mugs. After watching the video, go below it to read a story sent to me by one of my newsletter subscribers.

A True Coffee Mug Story

"We have practiced alternative medicine since 1984 when a gynecologist almost killed my wife. The doctor we were going to in the late 80's had tested us and found we both had lead poisoning. We didn't know the source, but one night a program like 20/20 came on, we never watched this program before.

They interviewed a pilot in the USAF and his wife. She was severely sick but no doctor could tell them what it was. The husband searched every article he could find on the
symptoms his wife had. After months, maybe years, he asked the doctor if he could test his wife for lead poisoning. Bingo, that was it.

This is the interesting part of the story. While in the Air Force, he was stationed in many countries each year. He would buy his wife stoneware coffee cups everywhere he went, she also traveled with him. The doctors had diagnosed her with a rare disease and had prescribed medicine that was taken with water. Each time she swallowed the pills/capsules, she downed it with one of the coffee cups. The cups were made with stoneware that had been fired with a glaze that contained lead.

My wife and I took our stoneware to our doctor and he tested us and sure enough, Bingo again. This was stoneware made in Mexico. We used it for years almost everyday.To detox we used a homeopathic liquid for maybe two months."

 

Lead in Old Pyrex Bowls

Lead in Pyrex Bowls - Do you own Pyrex bowls like this? The colored glaze you see might be contaminated with lead.

Lead in Old Pyrex Bowls

Do you have any old kitchen bowls like you see in the photo above? I grew up with bowls just like it.

In fact, each night for two years in the early 1970s I ate a pint of plain Skyline chili with onions and cheese in a red Prex bowl just like the one in the photo above.

Did you know these bowls might be contaminated with lead? Watch the video below.

Did you know there's NO SAFE exposure level to lead - especially with children? READ MY PAST COLUMN about Lead Poisoning.

Can I Use A Lead Test Kit to See if My Bowls Have Lead Glazing?

You can do whatever you want, but the Lead Test kits you find in stores are meant to test PAINT, not ceramic glaze.

To do a PROPER TEST, you need a hand-held XRF scanner that tests for lead and other heavy metals.

Watch this video. Then you DECIDE if your old Pyrex bowls are safe to use:

Lead in Bowl Glaze

Look at the chips and missing colored glaze on the outside of this bowl. How much of that might have transferred to my hands as I used the bowl?

pyrex bowl missing lead paint

The blue paint or glaze probably contains lead. All those chips and scratches mean lead could have been on your hands, in your food, or in your dishwater. Scary.

You can read another article about lead in Pyrex bowls here.

Lead in Newsletter Subscriber's Bowls

Carl is a subscriber and he sent me a story about lead in coffee mugs. After doing additional testing, Carl and his wife sent me this photo. Read what he says below it.

These Pyrex bowls belong to Carl and Patricia.

Tim,

The article on lead poisoning was very enlightening, Especially the video with Lead Safe Mama. We didn't realize these bowls from Pat's parents were a lead problem. We tested them and sure enough, even an older set of Correl bowls tested bad.

Thank you,

Carl and Patricia

How to Make a Roman Hypocaust Warm Floor

How to Make Your Bathroom Floor Warm as a Hypocaust

You may find this hard to believe, but I didn’t build the house I currently live in. It’s a long story but this current house in central New Hampshire was supposed to be a transition home while I did build a Queen Anne Victorian house for my family. Those plans were dashed by the horrible economic storm that affected millions in the autumn of 2008. It’s hard to believe that was fifteen years ago!

The builder who constructed my home took any number of shortcuts. I realize many of these may have been directed by the owner who could have been too cheap to invest in certain things. I do know the original owner and his wife only used it during the warmer summer months. That explains why each winter when my wife and I walk on our bathroom floor it feels like we were stepping onto the Athabasca Glacier.

New Hampshire winters can be brutal. The temperature can regularly dip to the single digits at night and never climb above 32 F for days at a time. Add to this a master bathroom that’s on the north end of the house with lots of windows and you have all the ingredients to create an extreme arctic-weather training simulator.

Remodeling Creates Opportunity

Several years ago I remodeled a basement bathroom part of which was under the master bathroom. Fortunately, the walk-out basement of my home has tall 11-foot 6-inch ceilings. I took advantage of this and created a lower ceiling over the basement shower and an adjacent closet. I now had easy access to the floor under the main part of the master bathroom.

My house has radiant hot-water heat and the current master bathroom only had two smaller wall-mounted radiators. These were not sized correctly and the bathroom would be icy cold on bitter days and nights. It would have taken the builder just three extra hours to install aluminum heat transfer plates under the wood subfloor in the bathroom. PEX radiant heating tubing could have been snapped into the transfer plates in less than 30 minutes. It’s not like radiant floor heating is a radically new concept. The Romans developed the hypocaust method of heating floors and walls thousands of years ago.

Aluminum Radiant Heat Transfer Plates

I ended up adding the heat transfer plates but it was a more involved project laying on my back in a cramped space above the basement bathroom. All the while I was mumbling about the lack of foresight of the original homeowner. Anyone who’s walked on a tile bathroom floor, even in a warmer climate, can tell you they’re always cold to the touch.

Above me are quite a few aluminum heat transfer plates and PEX radiant heating tubing. I installed this in my daughter's new home to heat a future Dad apartment over her garage. See the Uponor hePEX tubing in the Uponor radiant heat transfer plates? No wonder I'm so happy! Copyright 2023 Tim Carter

Once I completed the job the floor was instantly warm. I used an infrared thermal-imaging camera to capture the delicious warm heat transfer plates glowing in the photo.

You can create your own warm bathroom floor using hot water from a small water heater. You don’t need a big boiler as I have one that heats my entire home. A simple pump that’s connected to a thermostat sends hot water flowing through the tubing. You can even set up the pump to turn on and off with a timer or smart thermostat.

I installed a mat just like this to heat a small man cave I created for myself above my garage. The mat manufacturer works with you asking you how much heat you need so the mat provides the exact amount of comfort you require. In the case of my man cave, the mat had to create all the heat for the space. WATCH THE DIY VIDEOS BELOW.

If you’re remodeling a bathroom that already has a heat vent coming into it or an existing wall radiator, your mat will not need as much heating capacity to just make the floor warm. The mat is connected to a digital programmable thermostat or an app on your smartphone allowing you to easily control the temperature.

Installing the mat is not difficult. Most require that you embed the mat in a layer of cement thinset that you’d use to set ceramic tile. The manufacturer has step-by-step videos showing you how to do this. Once the thinset has dried, you then just cover the mat with a thin 1/4-inch layer of thinset.

Tile or laminate flooring can be installed directly on top of this second layer of the thinset. This layer of thinset acts as a heat sink and helps to ensure the temperature of the floor is distributed evenly so no matter where your bare foot steps, the floor is toasty warm. You can make it so warm that you may want to sleep on the floor in a sleeping bag!
