SunTouch UnderFloor mat is a perfect solution to warm nearly every type of floor covering. These special mats warm existing floors without having to replace the floor covering. If you have access under a floor, simply staple UnderFloor mats between the joists. The mat installs very easily underneath the subfloor and connects to 120 volt AC power. This 4 ft. by 16 in. 120V mat is great for installations in bathrooms, kitchens, entryways, or any room with cold floors and may also add warmth to the entire room while keeping your floors dry. The UnderFloor mat consists of an electric heating wire secured to a durable nylon mesh by a durable foil cover. The temperature of the floor is controlled with either the sunstat programmable or dial thermostats (sold separately). An in-depth installation manual is included.

Rated 4.8 out of 5 by 5 reviewers.
Rated 4.0 out of 5.0 by Can't be placed in mortar In case anyone else skimmed over the description the way I did, just know that this mat can NOT be mortared under tile. Even the shipping box is labeled with warning labels stating: "Caution, This product is UL Listed only for suspentsion between floor joists." The insturction manual makes it even more clear that you can not mortar this product. If you are a novice trying to make sense of all this, just know that if the picture of the warming mat is cased in blue, then you can't mortar the mat under the tile. If it's just the orange netting (no blue), then it can be mortared under the tile. At least, that's what it seems to me. January 2, 2009

Rated 5.0 out of 5.0 by easy install I ordered the 6' length for my bathroom. The install went great. I used the video from their website for some clarification. I also ordered the thermostat online as it was cheaper than picking it up in the store. Having an electric stapler really saves your arms as you spend a lot of time with your arms over your head.

Rated 5.0 out of 5.0 by Easy to install Great directions-- includes a video for how to program the thermostat. Very easy to understand. There are a lot of warnings and "no-no"s for installation, but if you follow all the directions you will be more than satistied with the results. September 6, 2011
Rated 5.0 out of 5.0 by It makes a great deal of difference in the crawl space that had been converted into an extra room just before I purchased the home. For the cost this is a good way to heat a room. It does require multiple junction boxes as you are limited in the number of wires for each metal electrical box. December 10, 2014
