How much does bathroom electrical work cost?

Bathroom electrical remodeling starts at $1,800 for a standard scope. Heated floors, steam showers, multi-zone lighting, and a new circuit run from a distant panel each add to it.

Does a bathroom need its own circuit?

Yes. Code requires a dedicated 20A circuit for bathroom receptacles, with GFCI protection. Heated floors and some ventilation-heat units need circuits of their own on top of that.

Can I add a heated floor to an existing bathroom?

If the floor is coming up as part of the remodel, yes — that is the right time. The mat needs a dedicated GFCI circuit and a thermostat location, both of which we plan before tile.

Why does my bathroom fan not clear the steam?

Usually undersized, ducted into the attic instead of outside, or switched off before the room dries. We size to the room, duct to the exterior, and wire humidity or timer control.

Bathroom electrical remodeling in Boise & the Treasure Valley

Bathrooms are small rooms with strict rules: GFCI protection, damp-location fixtures, ventilation, and increasingly heated floors and bidet power. Here is what the electrical portion involves.

What the scope usually includes

Vanity lighting, a shower or tub recessed fixture rated for the location, general ceiling light, a quiet exhaust fan sized to the room, GFCI-protected receptacles at the vanity, and often a dedicated circuit for a heated floor, bidet, or towel warmer.

Vanity lighting that people can shave and apply makeup under

A single fixture over the mirror throws shadows down the face. Sconces flanking the mirror at eye height, or a mirror with integrated light, do the job properly. We plan the box heights against the mirror size before the tile goes on.

Ventilation is an electrical decision too

Fan sizing follows the room volume, and quiet units are worth the difference. We run the duct to the exterior — never the attic — and wire humidity-sensing or timer control so the fan runs long enough to actually dry the room.

Heated floors, bidets, and modern loads

Heated floor mats need a dedicated GFCI circuit and a thermostat location planned around tile layout. Bidet seats need a receptacle behind the toilet that was not there in 1996. Both are trivial at rough-in and disruptive afterward.

Code items we hold to

GFCI protection on bathroom receptacles, a dedicated 20A circuit for the receptacles, damp or wet location listings for anything in or near the shower, and correct clearances from the tub. These are not negotiable and the inspector will look.

What we plan for

Sconces or integrated mirror lighting at usable eye height
Damp/wet-rated fixture in the shower or tub area
Quiet exhaust fan sized to room volume, ducted outside
Dedicated 20A GFCI-protected receptacle circuit
Planned power for heated floors, bidets, and towel warmers
Dimming on the vanity and ceiling for night use

Smart home electrical integration

Humidity-sensing fan controls, smart dimmers on the vanity, mirror power, and heated-floor thermostat planning turn a bathroom into a room that manages itself — all easiest to wire at rough-in.
