Radiant Floor Heating Cost: Per Square Foot in 2026
Estimate radiant floor heating cost per square foot — with the free HVAC calculator.
Radiant floor heating is the most comfortable heat there is — warm floors, no vents, no noise. It's a premium upgrade with a premium price. Here's the real 2026 cost.
THE SHORT ANSWER
The short answer
Radiant floor heating runs $6–$17 per sq ft installed in 2026 (electric $6–$12; hydronic $12–$25+). Including new flooring, expect $10–$40 per sq ft. A small bathroom runs $500–$1,700 total.
What it costs
Electric radiant mats run $6–$12 per sq ft installed. Hydronic (water) systems run $12–$25+ per sq ft. Including new flooring, the full project runs $10–$40 per sq ft. A small bathroom runs $500–$1,700; a whole house runs $8,000–$30,000.
- Electric: $6–$12 per sq ft
- Hydronic: $12–$25+
- With new flooring: $10–$40
- Whole house: $8,000–$30,000
Electric vs hydronic
Electric mats are the cheap path for one bathroom or a kitchen — thin, easy to install under tile. Hydronic pumps heated water through pipes — best for whole-house heat and lower operating costs, but expensive to install and needs a boiler or heat pump.
