Of all the upgrades we install, this is the one homeowners mention unprompted years later.
An electric mat or cable is set in mortar directly under the tile, controlled by a programmable thermostat. It warms the tile itself rather than the air. It's a supplement to your heating, not a replacement for it.
The Pacific Northwest has long, damp, cool stretches rather than extreme cold. Tile in an unheated Washington bathroom is genuinely 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.
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.
Lower than most people expect, because it's a small area on a timer. Most homeowners run it on a schedule — warm for the morning and evening, off otherwise. It's not a whole-home heating load.
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.
Worth it in a primary bathroom in this climate. Optional in a guest bath. Skip it in a powder room where nobody stands barefoot.
Material behaves differently in this climate than it does in a showroom in a dry state. Long damp winters, seasonal humidity swings and homes that predate modern vapor control all affect what holds up here. We spec for the Pacific Northwest, not for a catalog photo.

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.
