Buying Guide
What size should you choose? For small rooms, 20 sq ft kits are often sufficient; for larger bathrooms or open living spaces, 40–100 sq ft systems may be more cost-efficient per square foot and provide more even heat.
What type of underlayment is required? Most systems require embedding in a self-leveling underlayment or thinset mortar to ensure even heat transfer and avoid hot spots.
How important is a thermostat? A programmable thermostat with floor sensing improves comfort and energy efficiency. Look for models with GFCI protection, dual sensors, and a 7-day schedule.
Should you use an uncoupling membrane? Membranes help crack prevention and waterproofing under tile, especially in showers or wet areas. They can simplify installation and protect the tile over time.
What about safety features? GFCI protection, floor/air sensors, and a child lock are valuable for family safety, particularly in bathrooms and kitchens where moisture is present.
