Transform cold tile floors into warm, comfortable surfaces with the HeatTech 35 sq ft Electric Radiant Floor Heating Mat Kit (120V). Designed specifically for under-tile installation in bathrooms, kitchens, standing showers, and other moisture-prone spaces, this complete kit includes everything needed for a professional-quality heated floor system.

Why Choose HeatTech

The ultra-thin 1/8" heating cable installs directly under ceramic, porcelain, stone, granite, marble, or slate tile without significantly raising floor height. The self-adhesive mesh backing keeps the mat in position during installation. Cable is pre-spaced at 3" intervals for consistent, even heat distribution across the entire floor surface.

The included Honeywell/Aube 7-day programmable thermostat with floor-sensing capability lets you schedule heating times to match your routine and maximize energy efficiency. Typical energy savings range from 10–30% compared to non-programmable thermostats. The floor sensor (not an air sensor) ensures the thermostat responds directly to floor temperature for precise, responsive control.

Multiple 120V mats can be combined to heat up to 150 sq ft using a single thermostat, making it easy to expand coverage as needed. Ideal for DIY homeowners and professional installers alike.
