The Project Story: A Cold Floor Transformed

The owners of this beautiful home in Washington, MI, recognized that their master bathroom, despite its high-end tile, marble, or stone flooring, was suffering from the chilling effect of a cold subfloor—a common issue in northern climates. They were looking for a permanent comfort upgrade that would not only warm the surface of their floor but also provide an energy-efficient source of supplemental heat.

WarmlyYours collaborated with Beaver Tile & Stone on this project. The installer chose the TempZone™ Flex Roll for its ease of installation over the large, rectangular area of the master bathroom. Installation involved simply laying the roll directly on the wood subfloor and securing it before the tile installation could begin. The system was custom-designed for full coverage across the 78 square feet of floor space, ensuring uniform, wall-to-wall warmth. The result is a truly luxurious master bath experience where cold tile floors are now a distant memory, replaced by gentle, comforting in-floor heating.

The homeowner now enjoys a premium, energy-efficient heating solution that operates independently of their central HVAC system. The advanced nSpire Touch Thermostat provides easy programming, allowing them to schedule the radiant floor heating to activate when they need it most—first thing in the morning and before bed—making this master bathroom a true five-star retreat.


Featured Products 

  • TempZone™ Flex Roll (120V): This is the core of the electric floor heating system, consisting of thin heating cable pre-laced onto a roll-out mesh. The roll format simplifies installation, allowing quick coverage over large, regularly shaped areas like this master bathroom. Ideal for use under tile, stone, and marble floors.
  • nSpire Touch Thermostat (UDG4-4999): A sleek, fully programmable touch-screen thermostat that provides precise temperature control. It features a built-in Class A GFCI for safety and includes energy-monitoring capabilities to track and manage the system's energy efficiency.
  • Circuit Check: A required testing device used during installation to constantly monitor the heating cable for continuity, ensuring the cable is not damaged during the floor warming installation process.

* The 1,170-watt system costs approximately $0.25 per hour to run, based on Washington, MI's electricity rate of 21¢/kWh. Thanks to its energy-efficient radiant design and smart thermostat control, homeowners can expect a minimal daily cost of about $1.00 (for 4 hours of use), making luxurious in-floor heating remarkably affordable.

Frequently Asked Questions


This specific 78 sq. ft. master bathroom system costs about $0.25 per hour to run when heating, based on the local Washington, MI electricity rate of 21¢/kWh. If run for a conservative 4 hours a day, the monthly operating cost is less than $30. Electric radiant floor heating is a very energy-efficient heating solution for targeted comfort.
In many well-insulated, modern master bathrooms of this size (78 sq. ft.), the 1,170 W TempZone™ system can act as the primary heat source (full-room heat replacement). However, it is most often used as a powerful, energy-efficient comfort upgrade to deliver luxurious floor warming and supplemental heat, keeping the floor surface consistently warm.
The TempZone™ Flex Roll is specifically engineered for optimal performance under high-thermal-mass flooring materials like the tile, marble, or stone used in this Washington, MI master bath. These materials retain heat well and provide excellent, even heat transfer, maximizing the system's comfort and efficiency.
Yes. Electric floor heating is highly energy efficient because it uses line-of-sight radiant comfort to heat objects and people directly, rather than wasting energy heating the air (like forced-air systems). When paired with a programmable thermostat like the nSpire Touch, it only runs when needed, significantly lowering the overall operating cost and providing excellent energy savings.
