Hot mopping just might be the best way to waterproof your bathroom
Hot mop shower pans create waterproof seals by layering heated asphalt and felt, protecting your bathroom floor from leaks and moisture damage.
Installation costs range from $250 to $400, making hot mopping an affordable way to prevent expensive water damage repairs down the road.
Hot mopping lasts about 15 years with proper installation, giving you reliable bathroom waterproofing that keeps your home safe and dry.
Hiring a local shower repair professional keeps you safe from 400-degree asphalt burns and ensures your waterproofing works correctly from the start.
While a bit of water on the bathroom floor may seem like no biggie, water leaks can lead to serious structural damage. Leaks also encourage mold and mildew growth and cause costly water damage that’s frustrating to fix in the long term.
Thankfully, you have some options to keep your home safe and dry. Hot mop waterproofing is a great solution to pesky leaks and something to consider when remodeling, especially in bathrooms where it truly shines.
While “hot mopping” sounds like a heavy-duty cleaning method, it’s a fairly messy process. It’s a waterproofing method commonly used to waterproof bathroom floors that involves heating asphalt in a kettle and applying it between layers of felt using a large mop, hence the name. The layers meld together while they dry to create an impermeable waterproof seal.
This reliable waterproofing method seals off your shower and bathroom floor, preventing water from leaking onto the subfloor and ensuring there is no water damage to your home and none of the musty smells that come with it.
Don’t hesitate to call a pro when you have a plumbing issue or need repairs. While it’s tempting to wait, water damage from persistent leaks can cause serious problems, including mold and mildew, which pose a health risk. Additionally, the cost of water damage restoration can reach into the thousands.
Hot mopping requires workers to install layers of felt with heated asphalt, which makes for a messy and laborious installation. On the other hand, membrane waterproofing requires you to simply install liner sheets.
You can choose from Chlorinated Polyethylene (CPE) or Polyvinyl Chloride (PVC), and the process doesn’t require any heated asphalt. For this reason, DIYers tend to gravitate toward membrane waterproofing.
Another important thing to note is that hot mopping lasts 15 years, while CPE or PVC sheets can last decades longer.
While hot mopping is most commonly used to waterproof bathrooms, you can also use it to waterproof various home projects (think decks and indoor planters) as well as your roof. In fact, hot mopping is considered to be one of the best ways to cover and protect flat or low-slope roofs.
Overall, installing a hot mop under a shower pan is most common. When you take a shower, most of the water runs down the drain (as it should). Inevitably, though, your tile and grout absorb some of it, sending it to the shower pan below your shower. The hot mop shower pan method creates a reliable waterproof seal under the shower pan to prevent moisture from trickling into your floors and causing damage.
Hot mopping is the optimal way to waterproof your bathroom floor. Hot mop pans work better and last longer than other bathroom floor waterproofing methods, including vinyl liners. Opting for hot mop installation during a remodel will give you peace of mind, knowing that the risk of leakage and associated damages is virtually nonexistent.
Hot mopping helps lower humidity levels inside your bathroom, too. The lower the humidity, the less likely water is to infiltrate and damage your fixtures and appliances. Beyond that, hot mopping provides multiple layers of protection against all water leaks.
Hot mopping is a strenuous and dangerous project with plenty of room for error. The hot asphalt gets up to 400 degrees Fahrenheit, meaning you could seriously burn yourself if you make a mistake. And any missteps during installation could mean big problems later, like a shower pan leak. Not to mention that the strong smell of asphalt isn’t fun, either. So, if you’re looking into shower installation costs or shower pan replacement costs, it’s best to plan to hire a pro.
Hire a local shower installation contractor with hot mop experience for the best results. From start to finish, installing a hot mop shower pan will take a pro between one and two hours. Roofs may take a day or two to hot mop, and you should never attempt to go up on your roof, so definitely leave this one to a pro.
The cost of installing a hot mop shower pan is between $250 and $400. The cost will depend on the size of your project (hot mopping a roof, for example, will cost more than hot mopping a small shower).
