The best heated bathroom floors

Warm tile underfoot is the bathroom upgrade people remember. It is also the one you only get one chance to install, so the mat has to be right.

By Sawyer V. · · How we research

WarmlyYours TempZone Easy Mat, 120V, 3 x 6 ft

The short answer

For tile, buy the WarmlyYours TempZone Easy Mat sized to your floor: 15 watts per square foot, embedded in thinset under the tile, with a 25-year warranty. The 3 x 6 ft mat is 270 W — about 5 cents an hour to run. It needs a thermostat, sold separately, and an electrician.

How electric floor heat goes in

An electric floor-heating mat is a thin sheet of heating cable. It is laid on the subfloor, embedded in thinset, and tiled over. A cold lead runs from the mat to a thermostat on the wall, which reads a sensor in the floor and switches the mat on and off.

That means it goes in when the floor is being retiled, and not otherwise. It also means an electrician: the thermostat is wired in, and WarmlyYours says its nTrust 2.0 thermostat has “built-in GFCI” protection.

Watts per square foot, and sizing the mat

WarmlyYours designs its TempZone mats for 15 watts per square foot, which it describes as the maximum the National Electrical Code allows. The Environ runs at 12.

Size the mat to the floor you actually stand on. The space under a vanity, toilet or bath is not where your feet go, and a mat sized to the open floor keeps both the price and the running cost down.

What it costs to run

At the US average of 18.34 cents per kWh, the 270 W TempZone 3 x 6 ft mat costs about 5 cents an hour. Four hours a day — mornings and evenings on a schedule — is about 20 cents a day, or roughly $72 a year. The 107 W shower mat is about 2 cents an hour.

Those hours are our example. The thermostat decides how long the mat actually runs, and a programmable one is how you keep the cost to the times you are in the room.

What about plug-in heated floor mats?

There is a different product with a similar name: a portable heated mat you plug in and stand on. CozyFoot, for example, publishes a 120 W mat at about 140°F and says to use it “on hard, cold surfaces such as cement, tile, and stone”.

Its page says nothing about bathrooms or wet floors, and a plug-in heater on a floor that gets splashed is not something we will recommend without the manufacturer saying it is designed for it. For a renter’s cold bathroom floor, a good bath mat is the safe answer.

If you rent

Every mat here rates Owner-only on our install rating: it lives under the tile. Towel warmers against heated floors is compared here, and a plug-in towel warmer is the renter’s version of the same comfort.

The one to skip

Environ Easy Mat, 120V, 3 x 5 ft

WarmlyYours · ERT120-3.0x05 · best for laminate or carpeted rooms, not bathrooms

Built for floating floors and carpet, at 12 W per square foot and a shorter warranty — the wrong mat for tile.

The Environ Easy Mat is a good product for a different room.

WarmlyYours says it is “Commonly installed beneath carpet (US Only) and laminate”. It is an ultra-thin foil mat that needs no adhesive or cutting, which suits a floating floor. At 12 watts per square foot, it runs cooler than the TempZone’s 15.

Most bathroom floors are tile, and for tile the TempZone is the mat. The warranty tells the same story: 10 years under laminate and 5 under carpet, against 25 for the TempZone.
