What is the total cost to install heated floors in an Ottawa kitchen and mudroom?

The total cost to install electric radiant heated floors under tile in an Ottawa kitchen and mudroom depends heavily on the combined square footage, but for a typical installation covering 120 to 180 square feet (a mid-sized kitchen plus a mudroom entry), you are looking at roughly $3,500 to $7,500 all-in for the heated floor system, tile, and installation labour. That breaks down into several components.

The electric heating mats or cables themselves run $10 to $16 per square foot for quality brands like Schluter Ditra-Heat, Nuheat, or SunTouch. For 150 square feet, that is $1,500 to $2,400 for the heating system alone. The uncoupling membrane (Ditra-Heat or equivalent) adds $3 to $6 per square foot and is strongly recommended in Ottawa — our dramatic seasonal humidity swings cause wood subfloors to expand and contract, and the membrane protects the tile from that movement while also providing a channel system for the heating cables.

Tile material varies enormously based on your selection — budget porcelain starts at $3 per square foot while premium large-format porcelain or natural stone can run $15 to $30 per square foot. For a kitchen and mudroom, most Ottawa homeowners choose durable porcelain in the $5 to $12 per square foot range. Tile installation labour in Ottawa runs $7 to $15 per square foot, with the heated floor adding complexity that pushes toward the higher end of that range.

The electrical work is a separate line item. An ESA-licensed electrician needs to install the thermostat (or two thermostats if the kitchen and mudroom are on separate zones, which is recommended for independent temperature control), run a dedicated circuit from the panel, and connect everything with proper GFCI protection. Budget $500 to $1,200 for the electrical work including the thermostat, wiring, and ESA inspection.

Do not forget subfloor preparation — leveling compound, backer board if needed, and ensuring the subfloor meets flatness tolerances. This runs $2 to $6 per square foot and is absolutely critical to a successful installation.

For a mudroom specifically, I would strongly recommend epoxy grout rather than standard cementitious grout. Ottawa's five-month winter means your mudroom floor will be assaulted daily with road salt, melting snow, and grit tracked in on boots. Epoxy grout is waterproof and resistant to salt corrosion — it costs more upfront but will save you from regrouting every few years.

One practical tip: zoning the kitchen and mudroom separately gives you much better control over energy costs. You might want the mudroom floor warm in the morning when everyone is heading out the door, but the kitchen floor warm in the evening during meal prep. Two thermostats and two zones add perhaps $300 to $500 to the project but pay for themselves in energy savings and comfort.
