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 installation is only as good as the shower waterproofing kit that it’s installed with. A great shower waterproofing system ensures that your shower walls, backer boards, and subfloors are protected from water damage while providing additional benefits like eliminating the need for a traditional mud bed by incorporating a pre-sloped shower pan to direct water towards the drain.
The sheet membrane in the waterproofing system completely repels water while redirecting it towards the drain in the shower base, which means the tile and grout dries much faster—virtually eliminating any concerns about mold or mildew.
Because you don't have to build the mortar bed and then wait for it to cure, the use of these kits can greatly decrease the amount of time and effort needed to install a tile shower. Additionally, these kits can be easily installed since they don't require the use of proprietary boards, fasteners, or specialized tools.
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.
If your shower project includes a built in shower bench, don't forget to check out our TempZone™ Shower Bench Mats to make sure that surface is as comfortable as the rest of your heated shower!

1. Shower Pan Kits
These kits include a Pro GEN II shower pan (select the size and drain orientation that best fits your project), shower curb/s, a roll of waterproofing membrane, and a roll of waterproofing band. If you're installing a floor heating kit, make sure its size and drain orientation matches the shower pan kit.
2. Drain Assembly Kits
These Pro GEN II kits include a low profile riser, a riser ring, an easy-to-clean integrated hair trap, a yellow construction cover, and a drain flange made from either PVC or ABS to ensure a proper plumbing connection to existing plumbing.
3. Drain Grate Covers
These grate covers, available in either the economical Pro Series or the luxuriant Designer Series, are compatible with the Pro GEN II Drain Assembly and will friction fit within the drain riser. The screw-less installation of these grate covers allows for the integrated hair trap to be easily accessed and cleaned.
4. Shower Floor Heating Kits
In order to add a floor heating system to your shower waterproofing kit, you must make sure that the dimensions and drain orientation of the floor heating element and shower pan kit match. These kits include a TempZone Shower Mat, a Circuit Check, and an nSpire Touch programmable thermostat.
These are additional or replacement items for use with a Pro GEN II Shower Waterproofing System.
Frequently Asked Questions
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.
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
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.
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.
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.
Can this be tied in with the floor heating in the rest of the room or will they need to be on separate thermostats?
The shower floor heating kits can be tied into floor heating for the rest of the bathroom - allowing for one thermostat to control both areas as long as both areas are using less than 15 amps. When designing installation plans, we design with only one thermostat by default. If you prefer two separate thermostats, it might be a good idea, since the shower floor application is usually thicker and takes longer to heat. Be sure to let us know when discussing your quote with our team.
How can I tell if a particular thinset is modified or unmodified? What does "modified" mean?
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. Modified thinset is an industry term for any thinset mortar which has additives (usually latex or acrylic).
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.
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.
