Under-Tile Heating Mats for bathroom & kitchen renovations
Under-tile heating mats are the simplest way to add electric underfloor heating to a bathroom, kitchen or living area during a renovation. Our ultra-thin mats roll out directly onto your existing floor and sit right in the tile adhesive or in a cement screed. No major groundwork, and no added floor height.
Under tile heating mats
Renovating your bathroom, kitchen or living area? Under-tile heating mats are one of the most cost-effective ways to add luxury warmth to any tiled floor. During your renovation, the mat simply rolls out onto the existing surface before your tiles go down. A thermostat then keeps the floor at your preferred temperature; heating only when you need it.
How to install
Under-tile mats require no ducts, vents or wall-mounted consoles; just a power connection and a thermostat. Because everything is hidden beneath the floor, your walls and living space stay completely uncluttered. We recommend discussing the installation with your builder, architect or a specialist heating installer early in your renovation plan.
Calculate heating area
Measure the floor area you want to heat, then deduct any permanent fixtures like built-in wardrobes, kitchen benches or bathroom vanities; you only need to heat the open floor space. The worked examples below will help you choose the right mat size.
Living room example A
Heating area = 4.1m x 5.1m
= 20.9m²
Example A selection
Quantity: 2
Bedroom example B
Room area = 2.1m x 4.1m
= 8.6m²
Area of fixtures = 2m²
(wardrobe)
Heating area = 8.6m² - 2.0m²
= 6.6m²
Example B selection
Quantity: 1
Bathroom, toilet, laundry
example C
Room area = 2.0m x 3.75m
= 7.5m²
Area of fixtures = 2.2m²
(bath, shower, toilet, bench)
Heating area = 7.5m² - 2.2m²
= 5.3m²
Example C selection
Quantity: 1
Compatible floor coverings
Most floor coverings are suitable for use with underfloor heating; see the list below for compatible options.
Engineered wood flooring must only be installed on a fully dry subfloor. This typically means allowing the underfloor heating system to operate initially to help remove residual moisture from the concrete slab before installation.
Floor covering adhesives — Some water-based latex adhesives may soften or lose bond strength at temperatures above 40°C. For this reason, we recommend setting the underfloor heating thermostat to a maximum floor temperature of 25°C.

Gentle background warmth
Heat rises evenly from the entire floor surface, creating a consistent temperature from floor to ceiling — no cold spots, no hot blasts.
CSIRO research found that when floor-level temperatures reach around 16°C, people feel warm throughout their whole body. By contrast, people can still feel cold at floor level even when the air at head height exceeds 21°C.
Under-tile floor heating solves this by delivering warmth exactly where your body needs it most; right underfoot.
Health and safety
Because the system produces no smoke, fumes or circulating dust, it's an excellent choice for households with asthma sufferers or anyone with respiratory sensitivities.
With no exposed heating elements or burning surfaces, it's also completely safe around children, the elderly and pets.
Burning surfaces
Some other heating systems present hazards for children, the elderly or pets
Safety first
The system is securely encased in the floor and operates in silence
