A Powder Room Packed with Comfort

When homeowner and Instagram influencer Liz Dineen planned her powder room remodel, she knew she wanted to add a "wow" factor that would be felt, not just seen. While small, the 23 sq. ft. space featured beautiful (but notoriously cold) marble and tile flooring. The primary challenge was to add a high-end, modern amenity that would maximize comfort in the compact room without complex construction.

The TempZone™ Flex Roll system was the perfect solution. The 1.5-foot-wide roll was easily cut and turned to fit the powder room's exact layout, providing wall-to-wall warmth. The 120V system was simple to integrate into the home's existing electrical, and the project was paired with a sleek nSpire Touch thermostat for modern, programmable control.

The result is a powder room that defies its small size with an atmosphere of pure, luxurious comfort. The in-floor heating operates silently, providing consistent warmth from the ground up. Now, guests and family enjoy a pleasant, cozy experience, and the home boasts a valuable, modern amenity that perfectly complements the new tile.

TempZone™ Flex Roll Our most popular electric floor heating product, the TempZone™ Flex Roll provides 15 watts per sq. ft. for powerful warming. It features an adhesive backing and fiberglass mesh for simple, quick installation and is ideal for rectangular or slightly irregular spaces like this powder room.

nSpire Touch Thermostat This programmable touchscreen thermostat combines style and function. It features a large, 3.5” display, an intuitive setup wizard, energy-use monitoring, and a built-in Class A GFCI for safety, giving the homeowner complete control over their new radiant floor heating system.

Circuit Check A vital installation tool that continuously monitors the heating element before and during installation. The Circuit Check sounds an alarm if the heating roll is damaged, ensuring a perfect, reliable setup from start to finish.

* Based on current Oak Lawn, IL, electricity rates (approx. $0.145/kWh), this 23 sq. ft. system costs only about $0.05 per hour to operate. That’s just $0.41 per day (for 8 hours of use) or less than $12.50 per month—a small price for consistent, luxurious comfort.

Frequently Asked Questions


Operating costs are surprisingly low. For a 23 sq. ft. powder room like this one in Illinois, it costs only about $0.05 per hour to run. For a full 8-hour day, that's just $0.41, or under $12.50 per month, making it a very affordable luxury.
This project used tile and marble, which are ideal choices for radiant floor heating. Ceramic tile, marble, and stone are all excellent conductors of heat, warming up quickly and retaining that warmth efficiently. Our systems are also C-UL-us Listed for use with nearly all flooring types, including vinyl (LVT), laminate, and engineered wood.
es, electric radiant floor heating is highly energy efficient. It heats people and objects directly from the ground up, rather than trying to heat the air (like forced-air systems). This "zonal heating" warms only the room you're in, right where you feel it, which reduces heat loss and often allows you to lower your home's main thermostat.
In many cases, yes. While our systems are often used for supplemental comfort and floor warming, a TempZone™ system (at 12-15 watts/sq.ft.) can often serve as the primary heat source for a smaller, well-insulated room like a powder room, eliminating the need for bulky radiators or noisy vents.
