Shower Waterproofing Kits for Tile Showers

Tile showers are growing in popularity with homeowners and professionals alike because of how they naturally blend practicality and stunning design. However, a tile shower is only as good as the shower waterproofing kit that it’s installed with. A great shower waterproofing system ensures that your walls and subfloors are protected from water damage while providing additional benefits like eliminating the need for a traditional mud bed by incorporating a shower pan with a built-in slope to direct water towards the drain.

Our Pro GEN II Shower Waterproofing Kits are made from the highest quality materials and offer several key innovations over comparable tile shower kits such as:

  • An easy-to-clean integrated hair trap in the drain assembly
  • A stronger drain flange (rated at 780 PSI vs. the competition’s rating of 250 PSI)
  • A wider variety of high quality drain grate covers
  • A denser shower pan (3.5 lb/ft³ vs. the competition’s) which allows for the installation of a greater range of tile types, including glass tile

Combine Electric Floor Heating with a Shower Kit for Ultimate Luxury

For the very first time, electric floor heating can be combined with shower kits to create the ultimate bathroom remodeling kit. Relying on the shower’s water to heat a cold tile shower floor can waste time and water without ever delivering even heating. By combining a waterproofing kit and a floor heating kit, you can take the chill out of any tile shower.

Customer Questions & Answers

Will the installation of a TempZone floor heating system affect the height of my floor?

The TempZone™ twin conductor cable present in our TempZone™ products is comprised of a double-insulated, coaxial heating cable. The total thickness of the system can be between ⅛” and 5/32” thick and will not noticeably affect the height of your installed flooring.


What is the warranty for the TempZone floor heating system and for the shower waterproofing kits?

For the Floor Heating Systems:

The TempZone™ Shower Floor Heating Mat is covered by ourWarmlyYours’ 25-Year No Nonsense™ Warranty. In the event of a defect, we cover not only the repair or replacement of the TempZone™ system, but also any labor and materials required to perform the repair.


The nSpire Touch is covered by a 3-year limited warranty.


For the Pro GEN II Shower Waterproofing Kits:

Pro GEN II shower waterproofing materials come with a a lifetime limited warranty. 



How does the TempZone floor heating system work?

TempZone™ is an electric floor heating system that operates like an electric blanket for your floors. TempZone™ is covered in thinset, and is installed over the top of your shower pan and beneath your flooring. The system provides a warm, even temperature across your floor. The TempZone™ floor heating system is easy to install, operate, and maintain.


What is the typical operating cost of a TempZone Shower floor heating system?

The actual cost of operating your floor heating system will vary depending upon a number of factors including the cost of electricity in your area and the length of time you run your system. The WarmlyYours TempZone™ Shower Floor Heating Mat, for example, uses 15 watts per square foot. Based on a national average electricity rate of $.10/kW/hr, the approximate operating cost of an average bathroom using this system, measuring 4' x 4' would be as little as 4 cents a day. This cost is based on running your system a full 8 hours per day. Try our Operating Cost Calculator for a quick estimate.


Is the TempZone floor heating system safe for showers?

Yes. The WarmlyYours TempZone™ floor heating system has withstood rigorous safety testing by the Underwriter's Laboratory and has received the Wet Location UL listing for the U.S. as well cUL certification for Canada. WarmlyYours offers thermostats that carry the CSA Mark and the UL listing, which certifies that the product has been tested under extreme conditions and meets applicable standards for safety and/or performance in the U.S. and Canada. All WarmlyYours thermostats contain a Ground Fault Circuit Interrupter (GFCI) which provides fail-safe protection against an electrical shock.


The mat I bought is too big or too small. Can I add wire or remove wire to make it fit?

No. Never cut the heating mat. The floor heating mat is designed with a very specific resistance in order to consistently maintain heating at the chosen wattage per square foot. Trimming the heating cable in the mat would lower the resistance of the cable causing the system to overheat. Adding heating cable to the system would raise the resistance and the system would not heat properly.

If you think you have the wrong heating element, contact our 24/7 Technical Support Team by calling 1-800-875-5285. 


How many watts per square foot are delivered by the TempZone Shower Floor Heating Mats?

The TempZone™ Shower Mats are designed to deliver 15 watts per square foot, with the heating element positioned 3” apart on a serpentine loop attached to a fiber mesh.


Why is modified thinset better for my installation?

Modified thinsets are stronger once cured. Most have additional anti-crack features, and better initial tack/grab (AKA less “slump”). They also are required for use with porcelain and glass tile.


How can I tell if a particular thinset is modified or unmodified?

For shower kits, most of the modified thinsets you are looking for are listed as compliant with ANSI 118.4 and ANSI 118.11. Unmodified thinsets will be listed as compliant with ANSI 118.1.


What does "modified thinset" mean?

Modified thinset is an industry term for any thinset mortar which has additives (usually latex or acrylic).


How are Pro GEN II shower waterproofing kits better than the competition?

The Pro GEN II shower kits come with pre-formed pan. They have the same level of warranty as competing brands, but Pro GEN II shower kits have many improvements, and often total to a lower price than competitors.

  • The Pro GEN II shower kits use the Pro WP membrane which is rated at .07perm for water vapor, meaning it is the best protection you can get in a membrane system (nearly double the rating of the competitors)
  • The Pro GEN II shower kits are rated for use with modified thinsets, meaning a stronger install and ease of material sourcing (modified thinsets are often required for installing porcelain or glass tiles)
  • Our preformed pan system is stronger, featuring a denser foam pan, and a stronger drain flange
  • Our drain flange is supported by both the pan and the subfloor, meaning it is much stronger than the competitors' flanges which rely only on the pan for support. Our flanges even include a built-in removable and easy-to-clean hair trap inside the drain riser
  • The Pro Gen II shower kits are fully customizable with 3 pan options and multiple grate cover finishes to choose from


Should I install a traditional mud kit (drypack mortar and PVC liner / mortar and membrane) or use a pre-formed foam pan?

Pre-formed pans are easily modifiable and easy to install on any substrate. They are great for DIY, as well as for a fast and clean installation by a professional. Drypack kits do not work well for tiles smaller than 2" x 2" without additional work.


What additional tools and materials are needed to install a Pro GEN II shower waterproofing kit?

  • Jigsaw (for subfloor drain hole) & drill (for pilot hole)
  • Premium modified (Latex/Polymer) thinset mortar (not premixed)
  • 5-gallon bucket
  • Mixer and caulking gun
  • 3/16"x 3/16" square notch trowel
  • Margin trowel
  • Utility knife
  • PVC or ABS cement, and section of coupler pipe for connection
  • Level


What is included in a complete Pro Gen II shower waterproofing kit?

  • Shower pan
  • 108 sq. ft. of waterproofing membrane
  • 33 linear feet of waterproof joint band
