Radiant Floor Heating Cost: Per Sq Ft, By Room & System (4 References)

Radiant floor heating costs $6 to $20 per square foot installed, with national averages around $4,000 to $4,128 per project across three references.¹³ A single room runs $1,500 to $6,400; a whole house costs $10,000 to $34,000 (HomeGuide).² Running the system adds $65 to $250 per month in energy (HomeGuide).² Prices below are national averages* for 2026.

*National averages, not local quotes. Your price depends on system type (electric vs hydronic), square footage, whether new flooring goes on top, and local labor rates.

Quick math: a 160-sq-ft primary bathroom at HomeGuide’s $7 to $17 per square foot = $1,120 to $2,720, matching its own $1,100 to $2,700 table row, our arithmetic.² Angi’s $4,128 and Fixr’s $4,000 averages land within $128 of each other — different project pools agreeing that a typical job is a few thousand dollars, not tens of thousands.¹³ The big totals you see ($20,000+) are whole-house hydronic systems with a new boiler, our judgment.²

Cost per square foot by system type

System	Angi	HomeGuide	Fixr
Hydronic (water)	—	$7 – $17	$6 – $20
Electric (mats / wire)	$10 – $15 materials + $5 – $10 install	$8 – $15	$8 – $15
Solar	$8,000 – $19,500 whole-home	$7 – $17 + $3,000 – $9,000 heater	$18 – $25
Geothermal	$9,500 – $27,000 whole-home	$7 – $17 + $15,000 – $35,000 heat pump	$7 – $20
Propane	$2,400 – $2,900 whole-home	$7 – $17 + $2,800 – $7,500 boiler	$6 – $17

Electric and hydronic meet in the same $7 to $15 band per square foot; hydronic wins on operating cost for large areas, electric on install simplicity for single rooms (HomeGuide).² Homewyse’s independent electric estimate, $8.86 to $12.80 per square foot installed on an existing circuit, sits right inside the pack.⁴ Angi’s whole-home propane figure ($2,400 to $2,900) covers only the heat source on a small system, not full-house tubing at typical sizes, so it reads far below the others, our reading of their scope notes.¹

Cost by room

Room	Size (sq ft)	Heating only	With new flooring
Bathroom	40	$300 – $700	$600 – $1,600
Primary bathroom	160	$1,100 – $2,700	$2,400 – $6,400
Bedroom	120	$850 – $2,000	$1,500 – $3,200
Primary bedroom	224	$1,500 – $3,800	$3,300 – $9,000
Kitchen	160	$1,100 – $2,700	$2,100 – $4,300
Living room	320	$2,200 – $5,400	$4,100 – $8,600
Garage	400	$2,800 – $6,800	$4,400 – $10,000
Basement	1,000	$7,000 – $17,000	$11,000 – $25,000

All HomeGuide figures.² The “with new flooring” column adds $4 to $15 per square foot of floor covering on top of the heating system (HomeGuide).² Angi’s flooring-material averages tell the same story: tile tops the list at $30 per square foot, concrete $22.50, laminate and hardwood $17.50 each.¹

Whole-house costs

Scope	Cost	Source
Whole house, heating only (1,500–2,000 sq ft)	$10,000 – $34,000	HomeGuide
Whole house incl. boiler / heat pump	$12,000 – $43,000	HomeGuide
2,300-sq-ft home	$13,800 – $48,000	Angi
2,000 sq ft, heating only	$14,000 – $34,000	HomeGuide
1,000 sq ft	$6,000 – $25,000	Fixr

A new boiler adds $3,200 to $9,000 (HomeGuide) — see our boiler installation cost guide.² Most homeowners heat only bathrooms, kitchens, and primary bedrooms to keep totals in the low thousands (Angi).¹

Labor and other costs

Total labor runs $550 to $2,500 per project, with specialists charging $45 to $200 per hour for plumbing, $100 to $150 for flooring work, and $50 to $100 for the electrician who ties the system to the thermostat (Angi).¹ Every 1,000 square feet heated adds roughly 12 hours of labor (Angi), so a 2,000-sq-ft whole-home job carries about 24 labor hours, our arithmetic.¹ Site prep, debris disposal, and permits add $150 to $600 (Angi).¹

Running costs

Expect $65 to $250 per month in energy, depending on climate, zone count, and system type (HomeGuide).² Hydronic systems cost less to run on large areas because the boiler can be set to a lower temperature while delivering more consistent heat (Fixr).³

Worked examples

Example 1 — 40-sq-ft bathroom retrofit, electric mat. HomeGuide: $300 to $700 heating only.² Homewyse math: 40 sq ft at $8.86 to $12.80 = $354 to $512, inside the same band, our arithmetic.⁴

Example 2 — 160-sq-ft kitchen, hydronic, existing boiler. $1,100 to $2,700 for the floor system (HomeGuide).² If the boiler also needs replacing, add $3,200 to $9,000 (HomeGuide): $4,300 to $11,700 all-in, our arithmetic.²

Example 3 — whole house, 2,000 sq ft. $14,000 to $34,000 heating only (HomeGuide), or $12,000 to $43,000 including a new heat source (HomeGuide).² Angi’s 2,300-sq-ft band of $13,800 to $48,000 brackets the same project.¹

FAQ

Is radiant floor heating worth it? It delivers even heat at lower thermostat settings (Fixr), and bathrooms and kitchens are the highest-value rooms, our judgment.³ At $65 to $250 per month to run (HomeGuide), zone heating a few rooms beats heating the whole house for most budgets.²

Electric or hydronic? Electric for single rooms: cheaper to install, no boiler needed (HomeGuide).² Hydronic for large areas or whole-house: lower operating cost, but it needs a boiler or heat pump (HomeGuide, Fixr).²³

Can I install heated floors myself? Electric mat kits in a small bathroom are the most DIY-friendly version; the electrical hookup still needs a licensed electrician at $50 to $100 per hour (Angi).¹ Hydronic systems are pro work, our judgment.

Do heated floors work under any flooring? Tile conducts best and averages $30 per square foot all-in; laminate and hardwood average $17.50; concrete $22.50 (Angi).¹ Thick carpet insulates against the heat, our judgment.

How long does installation take? Roughly 12 labor hours per 1,000 square feet (Angi), so a bathroom takes a day or two including flooring work, our arithmetic.¹

DIY shopping: radiant floor heating mats (plain link, no affiliate relationship) — electric mat kits are the realistic DIY entry point for a single bathroom; hire the electrician for the hookup.
