In-floor heating comes up in nearly every bathroom renovation conversation we have. It sounds like a luxury add-on, and sometimes it is — but for a bathroom in a Brantford home, it's often one of the better upgrades you can make for the money. The key is understanding which system fits your project and what you're actually paying for.
Two types of in-floor heating: electric vs. hydronic
There are two fundamentally different ways to heat a bathroom floor, and they're not interchangeable. Which one you use depends on your bathroom, your house, and what stage you're at in the renovation.
Electric radiant mats are the most common choice for bathroom renovations. A thin heating cable or mat sits beneath the tile in a layer of thinset mortar, connected to a dedicated electrical circuit and a programmable thermostat. The whole system is typically 3–6mm thick — thin enough that it rarely raises your floor height enough to matter. Electric systems are best for single rooms (a bathroom, an ensuite, a mudroom) rather than whole-house heating.
Hydronic (water-based) systems circulate heated water through tubing embedded in a concrete slab or thick mortar bed. These are more efficient to run over large areas and are the standard for whole-home radiant heating — but they're expensive to install, require a boiler, and are almost never worth adding to a single bathroom unless you're already putting in hydronic heat throughout the house.
For a typical Brantford bathroom renovation, electric radiant is the right answer. That's what the rest of this post covers.
What in-floor heating actually costs in a Brantford bathroom
The cost of electric radiant floor heating breaks down into three parts: the mat itself, the thermostat, and the electrical work.
| Component | Typical cost |
|---|---|
| Electric heating mat (per sq ft, supplied) | $8–$14/sq ft |
| Programmable thermostat with floor sensor | $120–$350 |
| Electrician (dedicated circuit + connection) | $400–$800 |
| Installation (embedded in tile work) | Typically included in tile labour |
For a 60 sq ft main bathroom, expect to add roughly $1,500–$2,500 to your renovation budget for a properly installed electric radiant system with a quality thermostat. For a larger ensuite in the 100–130 sq ft range, budget $2,500–$4,000 installed.
These numbers assume you're already doing a full tile job — which you should be, because electric mats only make sense under tile or stone. Carpet and luxury vinyl plank are too insulating to heat efficiently, and laminate manufacturers typically void warranties when radiant is installed underneath.
The operating cost question
This comes up every time. The honest answer: a bathroom heating mat costs very little to run if you use a thermostat with a schedule.
A typical 60 sq ft bathroom mat draws around 600–900 watts. Run it for 2 hours in the morning and 1 hour in the evening at Ontario hydro rates (roughly $0.12–$0.17/kWh depending on time-of-use), and you're looking at $5–$10/month in the winter. Leave it running 24/7 with no schedule and that number climbs significantly — but no one who uses a programmable thermostat actually does that.
The systems we install come with thermostats that have floor sensors. You set a target floor temperature (typically 27–30°C for comfortable tile) and a schedule, and the mat only runs when the floor is below that temperature. In a well-insulated Brantford bathroom, it doesn't need to run much.
When we recommend it — and when we don't
In-floor heating is genuinely worth it in these situations:
- You're already tearing up the tile for a renovation (adding it to an existing floor means re-doing all the tile work — not cost-effective)
- The bathroom is over an unheated space like a garage or crawlspace, where floors run cold regardless of season
- The bathroom is used early in the morning in winter — this is where the comfort payoff is most obvious
- You're doing a primary ensuite and want to maximize the finish quality
We generally don't push it for a powder room (too small, rarely bare feet), a basement bathroom that already stays warm, or a secondary bathroom that gets light use. The math changes if it's a room people actually spend time in barefoot.
The best time to add in-floor heating is during a tile renovation — the mat installs in an afternoon and costs a fraction of what it would to retrofit later.
A note on permits and electrical
A dedicated circuit for a bathroom heating mat requires an electrical permit in Brantford. This isn't a technicality to skip — the circuit needs to be properly sized, GFCI protected, and inspected. If you're already pulling an electrical permit for your bathroom renovation (required any time you're adding circuits or moving fixtures), the heating circuit gets added to the same application. If this is the only electrical work, it's a straightforward standalone permit.
We coordinate this as part of the renovation. Your finished bathroom should have permits on file — it protects you at resale and ensures your insurer covers the work.
