Bathroom Electrical Remodel Cost in DFW: GFCI, Exhaust Fans & Vanity Circuits

Bathrooms are the most code-sensitive room in your house. Every outlet needs GFCI, every fixture over a tub or shower needs a wet-location rating, and every bath needs mechanical ventilation. Skipping any of it will fail inspection.

Required Circuits & Fixtures

1× 20-amp GFCI circuit for all receptacles (one bath or multiple, as long as it only serves bathroom outlets)

Separate lighting circuit (usually shared with adjacent hallway)

Exhaust fan ducted to exterior (attic dumps fail Texas code)

Wet-rated fixtures in shower area, damp-rated over tub

Bathroom GFCI outlet and vanity lighting installation

Common Bathroom Code Fails in Burleson & Fort Worth

Fan ducted into the attic — must exit through soffit or roof

2. Non-GFCI outlets within 6' of sink

3. Recessed light over tub without wet-location rating

4. Switch reachable from tub/shower (must be 3' minimum from tub edge)

No dedicated bath circuit — sharing with bedrooms triggers AFCI issues

Bathroom exhaust fan properly vented through roof

Heated Floors & Smart Mirrors

These need their own dedicated circuits:

Heated tile floor: 20-amp GFCI, mat wattage matters (0.5–1.5 kW typical)

Smart mirror w/ defog: 15-amp circuit, often shared with vanity lighting

Timeline

Simple GFCI swap: 45 min – 1 hr

New circuit + fan: 3–5 hrs (attic access dependent)

Full remodel electrical: 2–3 days rough + 1 day trim, spread across the remodel
