Heated bathroom floor installation in Dallas, under new tile
An electric heating mat or cable set in the thinset under your new tile, a sensor in the floor and a programmable thermostat on the wall. It goes in during a floor or remodel job.

Floor-heating systems we install in Dallas bathrooms include WarmlyYours, Schluter DITRA-HEAT and Nuheat, under Daltile and MSI porcelain.
Heated bathroom floor installation in Dallas lays an electric heating mat or cable in the thinset under new tile, with a floor sensor and a programmable thermostat. It goes in when the floor is being replaced, because it sits under the tile. Market data puts electric bathroom floor heat at about 8 to 15 dollars per square foot.
How a heated bathroom floor works, and when to add it
Tile and stone feel cold underfoot even in a warm house. An electric radiant system warms the floor itself, so the room feels comfortable without heating the air, and wet feet land on a warm surface.
In a bathroom the heat goes under the tile, so the time to add it is when the floor is being replaced or the room remodeled. Systems from WarmlyYours and Nuheat use mats; Schluter's DITRA-HEAT combines heating cable with an uncoupling membrane, which suits Dallas slabs that move.
Each system is tested for resistance out of the box, after it is laid, and after tile, so a damaged wire is caught before it is buried.
Heat just the floor, or the shower too?
| Floor only | Floor and shower | |
|---|---|---|
| Coverage | Open floor, vanity front, path to the shower | Adds the shower floor |
| System | Standard mat or cable in thinset | Cable within a rated waterproofing system |
| Market range | About 8 to 15 dollars per sq ft | About 15 to 20 dollars per sq ft in wet areas |
| Testing | Before, during and after tile | Plus a flood test with the cable in place |
| Best for | Most bathroom remodels | Curbless and walk-in showers |
| Drying | Floor dries faster | Shower floor dries faster too |
The three heated-floor setups we install
Electric Heating Mat Under New Tile
For most bathrooms, a pre-spaced heating mat is laid over the prepared floor, embedded in thinset or self-leveler, and tiled over. It covers the open floor where people stand, the vanity front and the path to the shower, not under cabinets or the toilet. The floor sensor sits between two heating runs so the thermostat reads the tile temperature, not the air. A small bathroom mat can often run on an existing GFCI-protected circuit if the load allows; larger areas get their own.
Planning range, heated floor in a 40 sq ft bathroom: $300 to $700 heating only; $600 to $1,600 with new flooring.
Heated Floor Into the Shower Zone
Heat can continue into a curbless or walk-in shower floor so the whole wet area stays warm and dries faster. Inside the shower, the heating cable has to sit within a waterproofing system rated for it, which is why systems like Schluter DITRA-HEAT with its matching membrane are used there. Market data puts heat in wet areas at about 15 to 20 dollars per square foot because of the membrane. The shower pan is flood-tested with the cable in place before tile.
Planning range, electric heated bathroom floor: $8 to $15 per square foot; $15 to $20 in wet areas with a membrane.
Thermostats and Programmable Controls
The thermostat decides whether the floor is warm when you want it and off when you do not. Programmable models heat the floor before your usual shower time and switch off after; smart models add phone control and energy tracking. Every thermostat for floor heat includes ground-fault protection and reads a floor sensor. We mount it outside the wet zone at switch height, and fit a second, spare sensor during installation, since a failed sensor under finished tile cannot be replaced.
What moves the price of a heated floor
The heating mat is the smaller part. These items decide the total.
Planning range, heated floor in a 40 sq ft bathroom: $300 to $700 heating only; $600 to $1,600 with new flooring. Market data, not a quote.
Heated area
Priced by the open floor that gets heat, not the whole room.
New floor
Heat is added under new tile, so the floor cost comes with it.
Shower zone
Heat inside the shower needs a rated membrane system.
Circuit
Larger areas need a dedicated circuit from the panel.
Thermostat
Programmable and smart thermostats cost more than basic ones.
Floor prep
Leveling a slab or stiffening a wood subfloor comes first.
Electrical permits for floor heat in Dallas
A heated floor is electrical work, and in Dallas that means an electrical permit, usually approved in a few business days. Where the system needs a new dedicated circuit from the panel, that is part of the same permit and inspection. We file it at the start of the floor or remodel job so the rough-in inspection lines up with the day the mat is laid, not a week after.

Installing floor heat yourself versus having us do it
| Task | Doing it yourself | Having us do it |
|---|---|---|
| Laying the mat | Doable with patience | Laid and resistance-tested at each stage |
| Wiring the thermostat | Needs a Dallas electrical permit | Permitted, wired and inspected |
| Protecting the wire while tiling | One trowel nick ends the system | Tested again before and after tile |
| Sensor placement | Easy to put under a hot spot | Set between runs, spare sensor added |
| Heat in the shower | Needs a rated membrane system | Installed and flood-tested |
