Bathroom Remodel Cost Estimator

Labor is the biggest gap. Licensed plumbers, tile setters, and electricians in Santa Clara and San Mateo counties bill among the highest rates in the country, and a bathroom is trade-heavy for its size. On top of that, most Bay Area housing stock is older, so walls often hide galvanized supply lines, cast iron drains, or undersized electrical that has to be brought up to current code once the permit is pulled. Permit review timelines also add carrying cost. National averages are built mostly from markets with none of those conditions.

It depends on what is left in the house. Buyers with young children look for at least one bathtub, so removing the only tub in the home can narrow your buyer pool. If the primary bath keeps a tub, or a hall bath still has one, converting a second bathroom to a walk-in shower usually helps rather than hurts. A curbless shower also reads as an aging-in-place feature, which is a real selling point in neighborhoods where owners plan to stay. Keep one tub somewhere in the house and the trade is generally a good one.

Plan on three to six weeks of construction for a straightforward bathroom, and six to ten weeks when the layout moves, custom tile is involved, or materials are on long lead times. Add one to three months ahead of that for design, permits, and ordering. The bathroom is unusable for nearly all of the construction window, so if it is the only full bath in the house, arrange a backup before demolition starts. Most homeowners with a second bathroom stay in place without much trouble.
