Seven kits below were checked on Amazon on October 11, 2026. The two WarmlyYours listings show no ratings, and several older kits changed or merged, so they were left out. Wattage and sizes come from Amazon listings. Hardwired thermostats and 240 volt kits should be installed by a licensed electrician.
A warm bathroom floor on a winter morning is hard to beat. Electric floor heating makes it simple. This guide covers how it works, what it costs and seven kits to look at.

How Electric Floor Heating Works
A thin cable or a mat is laid under the floor, usually under tile in thinset or under a floating floor. A thermostat with a floor sensor turns the power on and off to keep the floor at a set temperature, often between 80 and 85 degrees Fahrenheit. The floor then warms the room by radiant heat. You feel it through your feet first.
Looking ahead, electric floor heating is moving from luxury bathrooms to everyday remodels. Wi-Fi thermostats, thinner mats and peel-and-stick kits make a small install easy enough for a weekend. The catch is that heated floors are slow, and a floor warmer is not a whole-room heater in a cold climate.

The risk to watch is a bad install. A cable that is nicked, overlapped or covered in the wrong material can burn out or create a hot spot, and a mat under thick rugs or heavy furniture can overheat. Expect more kits with floor sensors and alarms. Test the resistance before and after the floor goes down, follow the maker spacing and use a GFCI thermostat.
Types of Radiant Floor Heating
- Heating cable. Flexible, fits odd shapes, and is laid in a pattern.
- Mats. Cable pre-spaced on a mesh. Faster to install.
- Roll or self-adhesive mats. Thin, good for floating floors or a quick install.
- Hydronic. Water tubes under the floor. Best for whole homes, and a pro job.
What It Costs to Run
Take the watts, divide by 1,000 and multiply by your rate. A 25 square foot kit at 300 watts costs about 5 cents an hour at 17 cents per kWh. A 100 square foot kit at 1,200 watts costs about 20 cents an hour. A thermostat with a timer and an insulation layer under the heater cut the bill. For more on costs, read how much electricity space heaters use.
Tips for Buying and Installing
- Measure the heated area only. Leave out cabinets, tubs and toilets.
- Match the kit to the floor. Tile and stone need a mat or cable with thinset. Laminate and vinyl need a kit made for floating floors.
- Use a floor sensor and a GFCI thermostat. It protects the floor and you.
- Test the resistance. Do it before, during and after the install.
- Never cut the heating cable. Cut only the mesh, as the maker says.
- Add insulation under the mat. It warms the floor faster and saves power.
- Do not put heavy rugs or furniture on top unless the maker allows it.
For small rooms, pair it with a heater like a bathroom heater or an electric wall heater. See how to choose the right size space heater for the room math.
FAQ
What temperature should a heated floor be?
Many people set 80 to 85 degrees Fahrenheit. Check the maker limit for your floor type.
Can you leave it on all the time?
You can, but a timer saves money. Set it to warm the floor before you get up.
Does it heat the whole room?
For a small room, partly. For a cold, big room, you need another heat source.
Is it safe in a bathroom?
Yes, with a GFCI thermostat and the right install.
Final Word
For a small bathroom, a 25 square foot HEATWAVE or Warming Systems kit is the easy pick. For a larger floor, check the SunTouch or the HEATIT mat for the size.
What happens next: expect more programmable, app-controlled thermostats and more kits sold for laminate and vinyl as well as tile. For a bathroom, kitchen or entry, a small heated floor is a comfort upgrade. For a whole home, a heat pump is still the better main heater.
