The national average cost to install radiant floors in your home is $5-$20 per square foot. Your installation and operating costs will depend on the type of radiant heat you use, size of the room or home, and cost to demo and install it. That means you can expect to pay anywhere from $450-$700 for electric floor heating in a small to medium-sized bathroom to $9,000-$20,000 to install floor heating to an entire 1,600 square foot home.
In-floor heating can be a wonderful way to add a bit of luxury to your home, and make chilly bathroom floors a thing of the past. Before you (or a heated floor installer) start tearing out tiles, use this guide to breakdown the cost to install radiant floor heating, the different types of radiant floor heating systems available, and how you can save money.
What affects the cost of installing radiant floor heating?
The size of the room you want to heat often determines both the type of floor heating system and overall installation costs. But unlike most construction jobs, the price per foot doesn't get cheaper with volume.
Smaller rooms, like a narrow bathroom, are actually more difficult to install subfloor heating in than a larger space like a bedroom or living room, thanks to how much electrical coil or hot water tubing it takes to heat a space. This is often reflected in a higher price per foot.
For example, a Thumbtack pro who specializes in heated floors in Long Island, NY installed a new electric heating system in a 40 square foot bathroom floor for:
Average costs to install radiant floor heating per square foot:
Size of room or home | Electric heating system | Hydronic heating system |
Bathroom (40 square feet) | $20-30 | $25-35 |
Bedroom (80-100 square feet) | $12-15 | $15-20 |
Living room (400 square feet) | $10-15 | $10-15 |
1,600 square foot home | $6-12 | $8-15 |
4,000 square foot home | $5-$10 | $6-10 |
Other factors that can add to the overall cost of a heated floor include:
Type of radiant heat
The two main types of radiant floor heating are electric and hydronic. On average, the cost of to install each of these floor systems is:
Labor and material costs may vary based on the size of the job, whether you're including this in a full home or remodel, and any unforeseen electrical or plumbing issues.
Electrical underfloor heating is essentially a heating mat wired with a curved grid of electrical wires. A 20-foot section of the mat (or series of mats in larger rooms) is installed into a thin-set layer of cement or mortar and laid beneath the tile. Once it's hooked up, you can turn on the grid and control it with a thermostat to heat the floor and room.
Electric systems are cheaper to install than wet' hydronic heating systems, since you don't have to install any pipes, tubing, or a boiler, but more expensive to operate. For that reason, a lot of people don't use electric heating systems to heat their entire home, but instead opt for directly heating specific locations, like a bathroom.
Keep in mind that even though electric systems are simple to install, every room is different. Hooking up the thermostat or additional wiring for the electrical floor heating system can cost as much as $450 extra for parts and labor.
The biggest difference between electric and hydronic or wet' subfloor heating is how much lower the operating costs will be after installation.
Instead of electrical wires, hydronic subfloor systems heat a room by pumping and circulating hot water through pipes laid under the floor. This makes this system more difficult and expensive to install than electrical radiant heating, but significantly more cost-effective to run, since water conducts heat so well.
Hydronic systems are commonly used to heat an entire home, and typically cost around $25 per square foot for parts and labor on a standard installationalthough contractors may charge as much as $30+ per square foot for harder to reach jobs, like a room on the second floor.
You may also have to install a dedicated boiler for your hydronic system, for an additional cost. Installing a 50-gallon heater can cost between $400-$800, and larger boiler systems (for an entire home) can cost thousands of dollars.
If you're using wood flooring, also be sure to ask about flooring options that won't warp or swell due to any moisture.
Flooring material
Your radiant heating system is only as good as the floor it's under. Maximize your heating efficiency (and comfort!) with the right flooring. Below are three common types of flooring, and how they mix (or don't) with radiant heating systems:

No matter what system you opt for, in-floor heating isn't cheap. Below are a few ways you can cut costswithout skimping on qualitywhen installing in-floor heat:
What are the pros and cons of subfloor heating?
Whether it's just your bathroom or your entire home, radiant systems come with their own unique set of pros and cons. Here are the pros and cons of having a radiant floor system in your home:
