Under-tile heating
Under-Tile Heating
Under-tile heating for Sydney and NSW bathrooms, laundries, kitchens and living areas, using electric mats below tile and stone floors.
Targeted room-by-room floor heating
Electric heating designed for tile and stone floors
Retrofit-friendly low-profile options
Thermostat and floor sensor control
Tile and stone floors
A practical way to warm compact tiled rooms.
Under-tile heating is one of the most common electric underfloor heating applications because tile and stone transfer heat well and are often used in smaller rooms.
It is especially useful in bathrooms, laundries and kitchens where a warm floor can make the room feel more comfortable without heating the whole home.
Mats and controls
Choose the mat and controls for your tiled floor
Check mat sizes and power ratings before choosing products, then review the controls for the room.

Under-tile benefits
Warm floors beneath tile and stone.
Under-tile electric heating places a low-profile heating mat below tile or stone floors for responsive comfort in smaller rooms.
Bathrooms
Warm floors in wet areas
A warm tiled floor can make bathrooms and laundries more comfortable underfoot.
Kitchens
Comfort in high-use rooms
Kitchen floor heating can add targeted warmth without changing the wider heating system.
Low profile
Useful for renovations
Heating mats can fit into compact floor build-ups when levels and waterproofing are coordinated.
Control
Timed warmth when needed
A thermostat and floor sensor can bring warmth on before morning or evening use.
Project flow
Planned around the tile set-out and heated area.
Under-tile heating should be coordinated before tiling begins so the heating mat, waterproofing, sensor and electrical connection are compatible.
- 01
Confirm the room and finish
Review the heated area, floor finish, floor build-up and project stage.
- 02
Select the heating layer
Match the electric heating product to the usable floor area and installation method.
- 03
Coordinate controls
Plan thermostat position, floor sensor routing and electrical connection requirements.
- 04
Install and test
Install below the finished floor system and complete electrical testing before handover.
Technical planning
Under-tile systems depend on the floor build-up.
The heating mat, adhesive layer, waterproofing, tile finish, sensor and electrical connection need to be compatible.
- Heated area
- Size the mat to the usable floor area, not the full room footprint.
- Wet areas
- Waterproofing and electrical requirements should be coordinated before installation.
- Floor sensor
- A floor sensor helps regulate the floor surface temperature and protect the finish.
- Testing
- Electrical testing should be completed at the required stages before the floor is finished.

FAQ
Common under-tile heating questions.
Where is under-tile heating most common?
It is commonly used in bathrooms, laundries, kitchens and tiled living areas where floor warmth is noticeable.
Can it be used in wet areas?
Yes, but waterproofing, floor sensor position, heated area and electrical requirements need to be coordinated with the installation method.
Does furniture affect the heated area?
Yes. Heating mats should normally avoid fixed cabinetry, vanities, wastes and permanent fixtures.
