Heated floors in New Jersey cost $1,500 to $4,000 added to a bathroom remodel for an electric mat system under new tile, and $8 to $20 per square foot for a hydronic (hot water) system in a whole floor, basement or addition. Electric is the right choice for one room that is being retiled anyway. Hydronic is the right choice for a large area, a new addition, a basement slab, or a house that already has a boiler.
Here is what each costs, what it costs to run, and where it makes sense.
Electric vs hydronic in one minute
| Electric mat or cable | Hydronic (hot water tubing) | |
|---|---|---|
| Best for | One bathroom, a kitchen, a mudroom, any room getting new tile | Whole floors, basements, additions, homes with a boiler |
| Installed cost (NJ 2026) | $12 – $25 per sq ft; $1,500 – $4,000 for a bathroom | $8 – $20 per sq ft; $6,000 – $25,000+ for a floor |
| Adds to the floor height | About 1/8 to 1/4 inch | 1/2 to 1-1/2 inches unless it goes in a new slab |
| Runs on | Its own 15- or 20-amp circuit and a floor thermostat | A boiler or water heater, manifold and pumps |
| Running cost | Higher per square foot; fine for a small room on a timer | Lowest cost per square foot of heat there is |
| Can it be the only heat in the room? | Sometimes, in a small well-insulated bathroom | Yes, it can heat the whole house |
| Repair if it fails | Usually pinpointed with a meter and fixed through one tile | Rare; PEX tubing lasts 50+ years |
Electric heated floors: the bathroom upgrade everyone keeps
An electric system is a thin heating cable or mat laid in the thinset under the tile, wired to a programmable floor thermostat. It takes the floor from cold to warm in 30 to 60 minutes, so it goes on a timer for the morning. In a typical 5x8 bathroom the mat, thermostat, GFCI circuit and labor add $1,500 to $2,500 to a remodel that is already replacing the tile. A large primary bath runs $2,500 to $4,000. It is almost never worth tearing up a good floor just to add it; do it when the floor is open anyway.
Running cost for that 5x8 bathroom, on two hours a day: roughly $8 to $15 a month at New Jersey electric rates. Leave it on all day and it is $40 or more.
Hydronic radiant: the whole-floor answer
Hydronic radiant runs warm water through PEX tubing in the floor: stapled under a wood subfloor, set in a lightweight pour over the subfloor, or embedded in a new concrete slab. It is the most comfortable heat there is, silent, dust-free, and it lets you run the boiler at a low temperature, which is efficient. It is also a real construction project.
Where it fits: a finished basement (tubing in or on the slab), a new addition, a garage or workshop slab, a whole-house remodel where the floors are coming up, or a house that already has a boiler and needs a new zone. In an existing house with finished floors that are staying, the cost of getting tubing under them usually kills it; that is where a mini-split or electric mats win.
Hydronic prices (NJ, 2026)
| Job | Typical range |
|---|---|
| Tubing in a new basement or garage slab (during the pour) | $4 – $8 per sq ft for tubing, plus the zone |
| Tubing stapled under an existing wood subfloor (from the basement) | $8 – $14 per sq ft |
| Tubing in a pour over the subfloor (floors coming up anyway) | $12 – $20 per sq ft |
| Add a radiant zone to an existing boiler (manifold, mixing valve, pump, controls) | $2,500 – $6,000 |
| Boiler or combi unit if the house has none | $7,500 – $16,000 |
| Typical 800 sq ft finished basement, tubing plus zone, existing boiler | $8,000 – $16,000 |
What to avoid
- Electric mats under laminate, vinyl plank or carpet without checking the flooring maker's rating. Many are not approved for it and the warranty dies.
- Any radiant under solid hardwood wider than 3 inches. Engineered wood only, and keep the floor under 80°F.
- Skipping the insulation under a slab or subfloor. Without it, half the heat goes into the ground.
- A mat with no floor sensor or a thermostat that only reads the air; the floor overheats or never warms.
- Hydronic without a mixing valve. A boiler at 180°F will cook a wood floor; radiant wants 90°F to 120°F water.
Does it add value?
In a bathroom, heated floors are one of the few small upgrades buyers actually mention in showings, and they cost less than the vanity. Whole-house radiant is a comfort decision more than a resale one; it will not return its cost the way a new front door does, but nobody who has lived with it goes back.
Questions people ask next
How much does it cost to add heated floors to a bathroom in NJ?
$1,500 to $4,000 added to a remodel that is already replacing the tile, including the mat, floor thermostat and dedicated GFCI circuit. Do it when the floor is open; retrofitting under a good floor rarely makes sense.
Is radiant floor heating expensive to run?
Electric mats in a small bathroom on a timer cost about $8 to $15 a month. Hydronic radiant is the cheapest way to heat a floor because the boiler runs at a low temperature and the heat is where you are.
Can heated floors be the only heat in a room?
Hydronic can heat a whole house. Electric mats can carry a small, well-insulated bathroom or mudroom but are not sized to be the only heat in a large or drafty room.
Can I put radiant heat under hardwood floors?
Under engineered hardwood, yes, with the floor temperature kept under about 80°F. Wide solid planks move too much with the heat and are not recommended.
How long do heated floors last?
Electric cable systems are typically warrantied 25 years and outlast the tile. PEX tubing in a hydronic system is rated for 50 years or more; the pumps and controls get replaced along the way.
