How much does it cost to install heated floors in a bathroom?

A 50-to-80 square foot North Shore primary bath runs $1,400 to $2,400 installed for an electric radiant mat, including thermostat, sensor, electrical hookup, and permit. Hydronic in a bath of that size rarely makes financial sense.

Is heated floor worth it?

In a primary bath or mudroom, yes. The cost is small relative to the daily comfort. In a basement, kitchen island area, or under hardwood, usually no. We cut it from scope on roughly 1 in 4 heated-floor conversations.

How long do heated floors last?

Electric mats and hydronic PEX both carry 25-year manufacturer warranties. In practice, an electric element fails most often from improper install (cut wires, undersized thermostat) rather than wear. A clean install with a UL thermostat and a properly placed floor sensor regularly lasts 30+ years.

Can you install heated floor over an existing concrete slab?

Yes for electric. The element goes in a self-leveling cement layer over the slab. Hydronic in this configuration requires a thicker pour and changes the floor height by 1.5 to 2 inches, which can throw off door swings and transitions.

Do heated floors raise home value?

Modestly in a primary bath, negligibly elsewhere. The 2025 Cost vs. Value report shows mid-range bath remodels recoup about 71 percent in our region. Heated floor is a comfort upgrade. Install it for the morning shower, not the resale spreadsheet.

Does heated floor work as the only heat source in a room?

In a tight, well-insulated room over a heated space, yes for electric in baths under 100 sq ft. For bigger rooms or rooms over crawl spaces, no. Use it as supplemental, not primary.

What is the cheapest way to install heated floors?

Add it to a remodel where the floor is already being demoed. The marginal cost is the element, sensor, thermostat, and a few hours of labor. Standalone retrofit jobs cost two to three times more per square foot because of demo and reset.

What floor types work best with radiant heat?

Tile and stone. Both transfer heat efficiently and tolerate temperature swings. Engineered LVP works. Hardwood and engineered wood work but limit you to lower output and floating installs. Carpet defeats the purpose.

Heated Floor Installation Cost: 2026 North Shore Pricing

Heated floors are one of the most-asked add-ons in our North Shore remodels. They are also one of the most over-installed. We have put electric mats and hydronic loops in roughly 200 bathrooms, kitchens, and mudrooms across Highland Park, Northbrook, Wilmette, Deerfield, and Glenview since 2010. This guide gives you real per-square-foot numbers, the rooms where heated floor pays back, and the rooms where we tell homeowners to skip it.

Direct answer. Heated floor installation cost in 2026 runs $8 to $15 per square foot installed for electric radiant mat systems and $20 to $25 per square foot installed for hydronic (water-based) systems. A 60-square-foot primary bath averages $700 to $900 in materials plus $400 to $600 in labor for an electric mat. A whole-floor hydronic install in a 1,200-square-foot first floor runs $24,000 to $30,000.

What is included in the per-square-foot number

Per-square-foot pricing in this category is messy because contractors quote it differently. Here is what our number includes and what it does not.

Included in our $8–$15 electric and $20–$25 hydronic numbers:

Heating element (mat, cable, or tubing)
Floor sensor + thermostat
Self-leveling underlayment when required
Electrical hookup or manifold tie-in
Labor to install element, sensor, and finish flooring on top
Permit and inspection (Cook County or local village)

Not included:

The finish floor itself (tile, engineered wood, LVP). Tile alone runs $10–$25 per square foot installed. See our porcelain tile installation services for material-specific pricing.
Subfloor repair or replacement
Demo of existing flooring
New circuit run or panel upgrade if the breaker panel is full
Boiler or water heater work (hydronic only)

When you compare quotes, ask each contractor to itemize these. A $6-per-square-foot quote that excludes the thermostat, the underlayment, and the electrician is not a $6 quote.

Electric vs. hydronic: which one for which job

The two systems work differently and the cost gap is real. Use this as the decision tree.

Electric radiant mat

Best for: bathrooms, kitchens, mudrooms, entryways, basements under 200 square feet.

Installed cost: $8 to $15 per square foot
Material cost alone: $4 to $8 per square foot
Labor: $4 to $7 per square foot
Operating cost: $1 to $3 per day for a 60-square-foot primary bath, depending on ComEd rates and run time

Electric mats sit directly under tile or LVP in a bed of self-leveling cement. They heat fast (15–30 minutes from cold) and run on a programmable thermostat. The capital cost is low and the install is clean. The tradeoff is operating cost. Electric resistance heat is the most expensive way to heat per BTU. Run a whole house on it and the ComEd bill will get your attention.

In a 60-square-foot primary bath running 4 hours per day in winter, expect about $20 to $40 per month added to your utility bill.

Hydronic radiant

Best for: whole-floor installs in new builds and gut renovations, full-home renovations where the boiler is being replaced anyway, large kitchen-and-living open plans over 600 square feet.

Installed cost: $20 to $25 per square foot
Material cost alone: $10 to $14 per square foot (PEX tubing, manifold, mixing valve)
Labor: $10 to $11 per square foot
Operating cost: 30 to 50 percent lower than electric for the same square footage when fed by a high-efficiency gas or heat-pump boiler

Hydronic systems pump warm water through PEX tubing under the floor. The floor is the radiator. They are slow to respond (1–3 hours from cold) and heat the room differently. In a properly designed install, the boiler runs at lower water temperatures than baseboard, which is what makes them efficient.

The capital cost is roughly double electric. They make sense when you are already opening the floor (gut reno, addition, basement finish), already replacing the boiler, or covering more than 400 to 500 square feet.

Quick rule

Under 200 sq ft, pick electric. Over 600 sq ft and you are doing other mechanical work, pick hydronic. The 200–600 sq ft middle is where the math gets specific to your project.

Real numbers from real North Shore projects

Where the money goes

Average breakdown for a 60-square-foot electric mat install:

Table:

Line item: Heating element + sensor | Share of total: 35%
Line item: Self-leveling underlayment | Share of total: 12%
Line item: Electrician + permit | Share of total: 18%
Line item: Thermostat | Share of total: 12%
Line item: Labor (set element, set finish floor) | Share of total: 23%

Average breakdown for a 1,000-square-foot hydronic install:

Table:

Line item: PEX tubing | Share of total: 18%
Line item: Manifold + mixing valve + zone controls | Share of total: 14%
Line item: Boiler tie-in or new boiler share | Share of total: 12%
Line item: Pour or screed over tubing | Share of total: 16%
Line item: Labor to lay loops + tie in | Share of total: 32%
Line item: Permit + plumbing inspection | Share of total: 8%

The thermostat line on electric installs is the easiest place to overspend. A standard programmable thermostat does the job for $80 to $120. The Wi-Fi smart units run $200 to $300. We do not push them. The floor sensor matters more than the user interface.

What we tell homeowners to skip

This is the cut list. We pull each of these out of scope on at least 1 in 4 heated-floor conversations.

1. Heated floor in a basement that is not waterproofed

Skip it. Always. If the basement leaks, the heated floor will not fix it and the warm slab can make a mold problem worse. Waterproof first. We cover this in our basement waterproofing services. Then talk about heated floor.

Saves: $2,000 to $6,000 in a typical 400 sq ft basement.

2. Heated floor under hardwood or engineered wood

Possible but rarely worth it. The wood acts as an insulator, which means the floor takes longer to warm up and runs at lower output. You also have to use floating engineered wood (no nails) and stay under 81°F floor surface temp or you risk gapping and cracking. The math almost never works.

Skip it unless the floor is already going to be engineered floating wood for another reason.

Saves: 100 percent of the heated floor scope on that area.

3. Whole-house electric mat

If somebody quoted you electric radiant for a 1,500 sq ft floor, get a second opinion. The capital cost gets close to hydronic and the operating cost is two to three times higher. The right question is whether hydronic plus a boiler swap pencils, not how to do the cheap version of the wrong system.

Saves: nothing on capital, but $1,500 to $4,000 per year on operating cost over a 20-year life.

4. Heated floor in a closet or laundry room

Cosmetic. Nobody stands in there long enough to notice. Cut it.

Saves: $400 to $1,200 per room.

5. Aftermarket smart-home integration

The heated floor's own thermostat is enough. We have seen homeowners spend $600 to $1,200 wiring heated floor into HomeKit or full Crestron systems. The use case is "preheat the bath floor on the drive home." A timer does that for free.

Saves: $600 to $1,200.

Permits and code in Cook County and Lake County

Heated floor work requires a permit in every North Shore village we work in. Highland Park, Northbrook, Wilmette, Deerfield, Glenview, Lake Forest all require an electrical permit for any new circuit and a plumbing permit for any hydronic tie-in. Cook County's electrical code follows the 2020 NEC with local amendments. GFCI protection is required on any heated floor circuit in a wet location (bath, kitchen, mudroom). The thermostat must be UL listed.

Permit costs in our service area run $90 to $260 depending on village. Inspection adds 1 to 5 business days to the project timeline. Skip the permit and you have no record of the install when you sell the house, and a buyer's home inspector will flag it.

Operating cost: what the ComEd or Nicor bill actually looks like

A 60 sq ft electric mat at 12 watts per square foot runs at 720 watts. At ComEd's 2026 average residential rate of about $0.16 per kWh, that is $0.115 per hour. Run it 4 hours per day, 5 months per year, and you add $69 per year to your bill.

A 1,000 sq ft hydronic system fed by a 95-percent gas boiler at Nicor's 2026 rate of about $0.85 per therm, running 8 hours per day during the heating season, adds roughly $310 to $480 per year. Resale-grade efficiency. According to the U.S. Department of Energy, radiant floor heating is more efficient than baseboard heating and usually more efficient than forced-air heating because it eliminates duct losses.

For ROI, the 2025 Remodeling Cost vs. Value report does not isolate heated floor as a line item, but mid-range bath remodels in the East North Central region (which includes Chicago) recoup about 71 percent at resale. Adding heated floor to a primary bath does not move that needle materially. It is a comfort upgrade, not an ROI play. Buy it for yourself, not the appraiser.

When in the project to install

Sequence matters. We see this go wrong on remodels where homeowners hire trades a la carte.

Demo old flooring and subfloor
Plumbing rough-in (toilet flange, vanity drain) if applicable
Electrical rough-in for the heated floor circuit and thermostat
Subfloor prep + cement board or self-leveler
Heated floor element install + sensor
Inspection (electrical, plumbing if hydronic)
Self-leveling thinset over element
Tile or LVP install on top
Thermostat finish + commissioning

Step 6 is the one homeowners forget. If the inspector cannot see the element before tile goes down, the inspection fails and you tear out tile. We have seen it. Schedule the inspection between step 5 and step 7.

Real timelines

60 sq ft primary bath, electric: 1 day for the heated floor scope, sandwiched in a 4 to 8 week bath remodel. See how long does a bathroom remodel take for the full timeline.
400 sq ft basement, electric: 2 days
1,000 sq ft first floor, hydronic gut reno: 3 to 5 days for the floor scope, inside an 8 to 14 week first-floor renovation

Three questions to ask any contractor quoting heated floor

Is the element warranty 25 years and is it transferable? (Industry standard. If they hedge, walk.)
Is the floor sensor included in the quote and is it installed in the floor, not just clipped to a baseboard? (A sensor in the wrong place gives you the wrong temperature.)
Have you pulled a heated-floor permit in this village in the last 12 months? (Local inspectors have local quirks. Veterans know them.)

If a contractor cannot answer all three with specifics, get another quote.

Heated floor in TCC projects: the fast path

We install heated floors as part of a kitchen or bath remodel, a floor leveling project like our Deerfield job, or a tile install like our Evanston project. Standalone heated-floor-only jobs are rare and usually do not pencil for either side because of the demo and reset costs. If you are already opening the floor, the marginal cost is small. If you are not, wait until you are.

We carry the EPA Lead-Safe certification, OSHA-trained crews, and pull our own permits. Same project manager from quote to handoff.

Cut-list takeaway

If you are installing heated floor in any room where you would not also install a heated towel bar, cut it. Comfort dollars belong in the rooms you stand still in.
