From Cold Tile to Cozy Retreat

When the owners of this Medina, Ohio, home decided to remodel their master bathroom, they chose beautiful, high-end tile and marble finishes. While visually stunning, these materials are notoriously cold to the touch, especially during Ohio's chilly months. Their goal was to create a comfortable, warm space to start and end their day, without seeing a huge spike in their energy bills. They turned to the experts at Architectural Justice to design a solution that matched the luxury of their new space.

Architectural Justice, a premier design and installation firm, recommended a WarmlyYours TempZone™ electric floor heating system. This solution is ideal for tile and marble floors as it provides consistent, even heat from the ground up. The team paired the 3.7-watt TempZone™ Cable with the Prodeso uncoupling membrane. This combination not only simplified the cable installation by providing easy spacing but also adds a critical layer of uncoupling protection, which helps prevent cracks in tile and stone flooring laid over a wood subfloor.

The result is a 97 sq. ft. master bathroom where 82 sq. ft. are now a source of luxurious, radiant warmth. The programmable nSpire Touch thermostat allows the homeowners to schedule the in-floor heating to be on only when they need it, maximizing comfort and efficiency. The homeowners now enjoy a true spa-like experience every day, stepping out of the shower onto a warm, welcoming floor, all thanks to the seamless integration of electric floor warming.


Featured Products

  • TempZone™ Floor Heating Cable: A flexible, 3.7-watt-per-foot cable that allows for custom configuration in any size or shape room. It was paired with the Prodeso uncoupling membrane for a fast and durable installation.
  • nSpire Touch Thermostat: A 7-day programmable thermostat with a vibrant touchscreen. It includes a built-in Class A GFCI for safety and a floor sensor to ensure precise temperature control.
  • Circuit Check: An essential installation tool that continuously monitors the heating system before, during, and after installation to alert the installer of any potential damage.

* This 82 sq. ft. radiant floor heating system costs just about $0.17 per hour to operate. Based on 8 hours of use per day, that's only $1.36 per day, or about $41 per month, to add luxurious comfort and spa-like warmth to this master bathroom (based on current Ohio residential electricity rates).

Frequently Asked Questions


The operating cost depends on the size of the heated area, local electricity rates, and how often you run it. This 82 sq. ft. bathroom system, for example, costs about $0.17 per hour. For a typical 8-hour daily schedule, that's just over $40 a month.
Electric in-floor heating works wonderfully with most flooring types. It is especially effective under tile, marble, and stone—like in this project—as these materials are excellent conductors of heat, making the floor feel incredibly warm and comfortable.
Yes. Radiant floor heating is very efficient because it heats the room's objects (including people) from the ground up, rather than just heating the air like forced-air systems. When paired with a programmable thermostat, you can schedule the heat for specific times, which prevents energy waste and reduces overall heating costs.
Absolutely. This project was installed over a wood subfloor. When installing under tile on a wood subfloor, it is highly recommended to use an uncoupling membrane, like the Prodeso membrane used here. This not only makes installing the cable easier but also protects the tile from cracking due to the natural movement of the wood.
