Radiant heat under stone flooring on a wood subfloor turns a 121 sq. ft. Dayton master bathroom into a warm, everyday retreat
This Dayton, Ohio master bathroom was finished in stone, a surface that doesn't hold warmth on its own. Remodeling Designs laid a WarmlyYours TempZone Flex Roll beneath 84 sq. ft. of that stone over a wood subfloor, so the floor is warm every time someone walks in. It runs on a 120V circuit and costs about $0.09 an hour to operate.

The Problem: A Stone Floor With No Warmth of Its Own
Stone gives a master bath a high-end look, but without a heat source beneath it, it stays at room temperature. For a bathroom used first thing in the morning and last thing at night, the homeowners wanted the floor itself to be warm, and the system had to work over a wood subfloor on a standard 120V circuit.
The Solution: TempZone Flex Roll Under 84 Sq. Ft. of Stone
Remodeling Designs specified a TempZone Flex Roll to cover 84 sq. ft. of the 121 sq. ft. room, installed over the wood subfloor and beneath the stone. The 1,625W system draws 13A at 120V. A Circuit Check was used during installation, and the floor is controlled by an nSpire Touch programmable thermostat with a 3.5-inch touchscreen.
The Outcome: A Master Bath Built for Bare Feet
The stone floor now delivers radiant warmth across the heated area, turning daily routines into a comfortable experience in every season. The homeowners manage comfort from the nSpire Touch thermostat and keep the look of natural stone.
Comparative Cost Highlight
Operating at approximately $0.09/hour, this system costs roughly $21.60/month at 8 hours a day—less than a daily cup of coffee—while providing unmatched barefoot comfort.
