Why Install Floor Heating in the Shower?
Heated shower floors and benches transform your daily routine into a spa experience. Our systems are specifically designed for wet environments.
Spa-Like Comfort
Step onto warm tile every time you shower. Heated floors and benches eliminate cold tile shock and make your shower a personal retreat.
Custom-Fit for Any Shower
TempZone Shower Mats and Cables fit floors, walls, and benches. Custom layouts ensure complete coverage for any shower size or shape.
Safe in Wet Areas
Installed beneath waterproofing layers and UL-listed for moisture-rich environments. Completely safe and invisible under your tile.
Affordable to Operate
Shower zones are small and cost just pennies per day to heat. Use our calculator below to estimate your costs.
Smart Thermostat Control
Program your shower floor to warm up before your morning alarm. Our WiFi-enabled thermostats handle the timing automatically.
Luxury That Sells
Heated shower floors are a premium feature that buyers notice. It's a relatively low-cost upgrade with high perceived value.
How Much Does Shower Floor Heating Cost?
Heated shower floors are one of the most affordable radiant heating projects because shower zones are small. TempZone Shower Floor Mats typically cost $10–$15 per square foot. For a standard 25 sq.ft. shower with about 15 heated square feet, expect to spend between $150 and $225 on the heating mat alone. Add a programmable thermostat ($100–$250) for a complete system.
Operating costs are minimal—a shower zone this size costs just $0.02–$0.05 per hour to run. Many homeowners program the thermostat to warm the shower floor for an hour or two each morning, keeping monthly costs well under $5. Use the calculator below to estimate your exact operating costs based on your shower size and local electricity rates.

How to Install Floor Heating in a Shower
TempZone Shower Mats install under tile in shower floors and benches. The key difference from standard floor heating is the waterproofing step—a waterproofing membrane must be applied over the entire assembly before tile is installed. Our shower mats are UL-listed for wet environments.
Step-by-Step Installation
- Step 1: Ensure the shower pan or substrate is properly sloped for drainage and structurally sound.
- Step 2: Apply a layer of modified thinset to the shower floor or bench surface.
- Step 3: Press the TempZone Shower Mat into the thinset, following your SmartPlan layout.
- Step 4: Test the heating system with an ohmmeter—check resistance before, during, and after installation.
- Step 5: Apply a waterproofing membrane over the entire assembly, including the mat and all seams.
- Step 6: Install tile over the waterproofing membrane using modified thinset and the back-butter method.
- Step 7: Allow thinset to fully cure before turning on the heating system. Wire the thermostat and enjoy!
Important Considerations
- Waterproofing is mandatory: A waterproofing membrane must cover the entire heated area, the mat, and all seams. This protects both the heating element and the structure beneath.
- UL-listed for wet locations: TempZone Shower Mats are specifically listed for use in moisture-rich environments including shower floors and benches.
- Curbless showers: For curbless or walk-in showers, check out our detailed installation guides for waterproofing techniques specific to barrier-free designs.
