Calgary Winters Make This a No-Brainer
If you’re gutting your bathroom anyway, heated floors are the single best comfort upgrade you can add for the cost. Stepping onto a warm floor on a −20°C Calgary morning is genuinely life-changing.
Two Main Types
Electric Radiant (Mat or Wire)
Thin heating cables embedded in a mat, installed under tile. The most common choice for Calgary bathroom renovations.
- Lower upfront cost
- Easy to install in single rooms
- Costs $50-$100/month to run (one bathroom)
- Best for bathrooms under 100 sq ft
Hydronic (Hot Water)
PEX tubing with circulating hot water, usually tied into a boiler. More common in whole-home retrofits or custom builds.
- Higher upfront cost
- Cheaper to run (especially if you already have a boiler)
- Better for larger areas or whole-home installations
- Needs a boiler or dedicated water heater
Cost in Calgary (Installed)
| Bathroom Size | Electric Radiant | Hydronic (Add-on) |
|---|---|---|
| Powder room (20 sq ft) | $500 – $900 | N/A (too small) |
| 3-piece (45 sq ft) | $900 – $1,800 | $2,500 – $4,500 |
| 5-piece ensuite (100 sq ft) | $1,800 – $3,200 | $4,500 – $8,000 |

⚠ Estimate Disclaimer: These are only ROUGH estimates that can vary wildly. Do not take these numbers as gospel. Having a defined scope of work and exact selections will give you clarity.
Includes mat/wire, thermostat, labour, and extra self-leveller if required.
Do You Need a Special Thermostat?
Yes. A floor-sensor thermostat is required for heated floors (programmable is best). Popular choices: Schluter DITRA-HEAT DHERT, Nuheat, Warmly Yours, Honeywell. Expect $200-$400 for the thermostat alone.
Where to Install It
- Always: Under tile floor in front of the vanity and toilet
- Highly recommended: Bathroom/ensuite floor fully covered
- Luxury: Extend into the shower (yes, this is amazing)
- Consider: Heated bench in the shower
What It Costs to Run
Electric radiant uses about 12 watts per sq ft. A 45 sq ft bathroom heated 8 hours/day in Calgary winter costs around $15-$25/month on top of your normal electricity bill. Most homeowners run it only during morning/evening routines.
Is It Worth It?
Yes. If you’re already tiling the floor, the incremental cost is $800-$2,000. That’s the best-value luxury upgrade in your whole bathroom. Almost every bathroom renovation we do in Calgary includes heated floors now.
Install Gotchas
- Don’t put heat under the vanity or bathtub (wasted heat, can damage cabinetry)
- Don’t install under a floor drain
- Use self-levelling compound over the mats before tiling
- Run a dedicated 15A or 20A circuit
- Never trim heating wires — they’re a fixed length
