Answer a few quick questions and we'll match you with the best floor heating system.
Why Install a Heated Tile Floor?
Tile and stone are the ideal conductors for radiant heat—they heat up fast, retain warmth beautifully, and feel luxurious underfoot.
Perfect Heat Conductor
Tile and stone transfer heat more efficiently than any other flooring. Your floors reach target temperature faster and hold warmth longer.
No More Cold Tile Shock
Cold tile floors are the #1 complaint homeowners have. Radiant heating eliminates cold tile forever—every step on a heated tile floor is warm and comfortable.
Low Operating Cost
Tile's thermal conductivity means lower energy costs. A typical heated tile floor costs just C$0.07–C$0.36/hour. Use our calculator below to estimate.
Installs During Tiling
TempZone mats and cables install right in the thinset layer—the same thinset you need for your tile. No extra construction step required.
Clean & Energy Efficient
No fans, no ductwork, no circulating dust. Radiant heat warms objects directly and is more efficient than forced-air systems.
Boosts Home Value
Heated tile floors are a premium luxury upgrade. 20% of home buyers consider radiant floor heating a desired feature.

Your Dream Remodel isn't Complete without a Heated Tile Floor
Cold mornings can be a challenge — the alarm clock rings, signaling that it's time to get out of your warm, cocoon-like bed, but you dread having to step foot onto the cold tile floor as you make your way to the shower. If your bathroom had a heated tile floor, wouldn't mornings be just a little easier to embrace?
With the installation of under tile floor heating, your heated tile floor will remain consistently comfortable day after day. Find the ideal solution to warm tile, marble, or stone floors with electric in-floor heating. Combine the beauty of tile and stone with the luxury of barefoot radiant comfort.
Our systems for under tile floor heating come in rolls, mats, or in cable that can be installed with either an uncoupling membrane or with fixing strips that can be glued to the subfloor or adhered with double sided tape. The heating elements are then embedded in self-leveling cement or thinset with the floor covering installed on top. We offer a wide variety of control and thermostat options for operating your heated tile floor system, ranging from a simple set-it-and-forget-it model to a WiFi enabled programmable thermostat with a touchscreen.
Under tile floor heating systems generate an even heat throughout your home and will not disturb dust, reducing the chance of possible allergic reactions. What's more, a heated tile floor will reduce noise levels and the amount of dry air in your home and is energy efficient.
WarmlyYours provides free design services to make sure that customers purchase the under tile floor heating system that best meets their project requirements. Depending on the floor type and the shape and size of a room's layout, the size and placement of heating mats will differ. Ensuring you have the right sized heating elements is the first step to achieving the perfect heated tile floor.

How Much Does Tile Floor Heating Cost?
The cost of heated tile floors depends on the heating system and room size. TempZone Flex Rolls typically cost C$12–C$15 per square foot, while TempZone Cable with fixing strips costs around C$6–C$10 per square foot. For a standard 35 sq.ft. bathroom with about 25 heated square feet, expect to spend between C$150 and C$375 on heating materials.
Tile and stone are among the best conductors of radiant heat, meaning your heated tile floor will warm up quickly and operate efficiently. Most homeowners spend less than C$1 per day to heat a single bathroom zone. Use the calculator below to estimate your exact operating costs based on your room size and local electricity rates.

How to Install Floor Heating Under Tile, Marble, or Stone
Tile, marble, and stone floors are ideal for radiant heating because the heating element installs right in the thinset mortar layer—the same material you already need for tile. You can use TempZone Flex Rolls for large, rectangular areas or TempZone Cable with fixing strips for irregularly shaped rooms. For extra crack-prevention, pair TempZone Cable with our Prodeso Uncoupling Membrane.
Step-by-Step Installation
- Step 1: Clean and level the subfloor, making sure it is free of dirt, dust, and debris.
- Step 2: Use your SmartPlan installation plan to mark the placement of the heating mat or cable.
- Step 3: Roll out TempZone Flex Roll (cutting the mesh to turn at row ends) or install TempZone Cable with fixing strips per your SmartPlan layout.
- Step 4: Test the heating system with an ohmmeter—check resistance before, during, and after installation.
- Step 5: Apply modified thinset over the heating element with a trowel, fully embedding the mat or cable.
- Step 6: Install tile, marble, or stone over the thinset layer using standard tile-setting techniques.
- Step 7: Allow the thinset to fully cure before turning on the system. Wire the thermostat and enjoy your heated floors.
Compatibility Tips
- Best conductors: Tile and stone are among the best flooring materials for radiant heat—they warm up quickly and hold heat longer than almost any other surface.
- Prodeso Membrane option: For tile-over-concrete installations, pairing TempZone Cable with the Prodeso Uncoupling Membrane protects against cracking tiles and speeds up installation time.
- Thinset selection: Use a modified (polymer-modified) thinset mortar for best adhesion and heat transfer. Unmodified thinset may crack over time with thermal cycling.

Questions & Answers for Floor Heating under Tile
Showing all 6 questions
No, an uneven subfloor can cause tile lippage and stress the radiant heating cables, leading to cracks or system failure. Always level the subfloor using a self-leveling compound or patching material first. This creates a stable, flat surface that protects the heating elements and ensures a professional finish.

Always level the subfloor using a self-leveling compound or patching material first. This creates a stable, flat surface that protects the heating elements and ensures a professional finish.
To protect heating cables, always test resistance with an ohmmeter at every stage. Use a plastic notched trowel to avoid nicks, and never cut or shorten the heating cable. Promptly remove excess thinset from grout joints using a wooden stick or plastic tool rather than a sharp metal blade.
