Are Heated Bathroom Floors Worth It in the Pacific Northwest?
How electric radiant floor heat works under tile, what it costs to run, and whether it's worth it in a Washington bathroom.
The short answer
Heated floors are a small, intermittent electrical load on a timer, not a whole-house heating system. The decision is almost always made on comfort rather than economics. Install it while the floor is already open — retrofitting later means taking the tile up again.
Heated floors are one of the few upgrades that get used every single day of the wet season.
How it actually works
An electric mat or cable is set in mortar directly under the tile, controlled by a programmable thermostat. It warms the tile itself not the air. It's a supplement to your heating, not a replacement for it.
Why it fits this climate
The Pacific Northwest has long, damp, cool stretches rather than extreme cold. Tile in an unheated Washington bathroom is unpleasant for a large part of the year. Radiant heat addresses exactly that, and it also helps the floor dry faster — which matters for mold.
Cost to install
The material is a modest share of a bathroom budget. The reason to do it during a remodel is that the floor is already coming up — retrofitting later means demolishing the tile you just paid for. If you're tiling a bathroom floor and even slightly considering it, do it now.
What it costs to run
An electric floor-warming mat is a small, intermittent load — it heats roughly 30 square feet of tile on a timer, not a whole house. Compared with running the furnace to make one cold room bearable in the morning, most people find it cheaper, not more expensive.
If you want the exact figure for your own bathroom, it is easy to work out: the mat manufacturer publishes watts per square foot, multiply by your heated area and your daily run time, and check your own PSE bill for your rate and schedule. A time-of-use plan changes the answer substantially, which is why we would rather you ran your own numbers than trusted ours.
What can go wrong
The failure mode is a damaged cable during installation, which is difficult to repair under finished tile. Testing continuity before, during and after the mortar goes down is essential — a good installer tests at every stage.
Our take
Worth it in a primary bathroom in this climate. Optional in a guest bath. Skip it in a powder room where nobody stands barefoot.

Can you help me choose materials?
Yes, and we'll tell you when a cheaper option is fine. We'd rather you spend the money where it matters.
Do you supply materials or do I?
Either works. Some clients want to select and purchase their own finishes; most prefer we handle it. We're happy with either as long as it's clear up front.
