Giving your bathroom the proper waterproofing is one of the most important aspects of any bathroom remodel. Without waterproofing, moisture can penetrate the gypsum board and vinyl wallpaper, leading to major problems like wood rot, mold growth, and structural damage. Additionally, water vapor can fill your home with humidity which could pose a health hazard to occupants. If you don’t want to risk doing it yourself, you should definitely contact a professional plumber like Mister Plumber.

There are some key steps to ensure moisture stays out of your walls and floors:

  • First, it’s important to make sure that any existing seams and corners are properly caulked and sealed before beginning wallcoverings or floorcoverings like tiles.
  • Additionally, all seams must be covered with water-resistant tape or tar strips in order for the barriers used in waterproofing to actually be effective at keeping moisture out- otherwise water will still seep through them at points where there aren’t any sealers connected.
  • Finally, you should also properly install a vapor barrier against the exterior walls of your bathroom beforehand. This will serve as an additional layer of protection against potential moisture infiltration while also preventing condensation from forming on cool surfaces within the room space due to temperature fluctuations between the interior and exterior environment.

Waterproofing a bathroom yourself can be a daunting task, but it can be done and done properly to ensure that your bathroom remains moisture-free and intact. To ensure a successful outcome, there are some key mistakes to avoid throughout the process which can ultimately prevent serious water damage and costly repairs down the line.

When waterproofing your bathroom yourself, here are some of the most common mistakes you should avoid:

  • Not prepping correctly – Before starting, you must first ascertain whether or not there is any existing water damage or moisture accumulation in your bathroom that requires remediation prior to waterproofing. Skipping this important step can cause serious issues down the line.
  • Overlooking small details – Attention to detail is key when it comes to waterproofing bathrooms, often homeowners fail to account for minute details such as corners, window frames and seals around drains which can allow moisture into the room if improperly sealed.
  • Using incorrect sealant – Incorrect sealants used on joint points of tile grout or sheet materials will not protect them from moisture seepage. Using the wrong sealants could be a costly mistake that would result in cracking in your tiles over time due to movement caused by water damage.


Taking the time to properly waterproof your bathroom will pay off in the long run. While it can be tempting to take shortcuts so that you can save money and time, they may end up costing more in the future if water is able to infiltrate behind tiled walls or in other areas of the bathroom. If done correctly and following manufacturer instructions, waterproofing your bathroom can help prevent damaging moisture buildup behind wall tiles and on other surfaces.
