Willow Kitchen & Bath Remodeling

Bathtub Replacement on the Peninsula

Replacing a tub is never just the tub. The walls around it come down to the studs, the valve and drain are replaced, and new waterproofing and tile go up. We do it as a bathroom refresh, usually in about two weeks.

Line items and what moves the price: bathroom remodel cost in the Bay Area.

When a tub needs replacing

  • It leaks or flexes. Fiberglass and acrylic tubs crack at the drain or the floor; steel tubs rust through at chips.
  • The finish is gone and has already been refinished once or twice.
  • It is the wrong tub. Too shallow to soak in, too tall to step over, or the wrong length for the room.
  • The walls around it have failed. Loose tile, soft drywall or mold behind the surround means the walls are coming off anyway.

If the tub itself is sound and you only dislike the surface, refinishing is the cheaper answer. Our sister company does that, and we will tell you if that is all you need.

What a replacement includes

  1. Demolition: the old tub and the wall tile around it down to the studs, with the room sealed.
  2. Framing: new ledger and blocking for the tub, and repairs to any subfloor rot we find. Rot is priced in writing before we fix it.
  3. Plumbing: a new valve, overflow and drain, and a pressure test.
  4. The tub: set level and supported along its length, so it does not flex.
  5. Waterproofing and tile: a bonded membrane over the tub flange, then tile to the ceiling or to 72 inches.
  6. Finish: tub spout, showerhead, glass or curtain rod, caulk and paint.

Which tub

TubGood forWatch out for
Enameled steelHall baths on a budget; stiff and durableChips can rust
Acrylic alcove or soakerMost remodels; warm to the touch, many sizesNeeds a proper mortar or foam bed underneath
Cast ironLongest life, holds heatVery heavy; second floors need a framing check
FreestandingPrimary baths with floor spaceFloor-mounted filler means plumbing through the floor

Freestanding tubs

A freestanding tub needs room around it to clean and to get in, and a filler that rises from the floor or comes off the wall. The drain and supply lines are set before the floor tile goes down, so the tub has to be chosen, and its drain position known, before demolition.

Bathtub replacement questions

Can you replace just the tub and keep my tile?

Almost never. The tub's flange sits behind the bottom row of tile and the waterproofing laps over it, so the wall tile has to come off at least to the first course, and usually to the studs.

Should I refinish my tub instead?

If the tub is sound and the shape works, refinishing costs far less and takes a day. If it leaks, flexes, is the wrong size or you want a different tub, replace it.

Will a cast-iron tub come out in one piece?

Rarely. Cast-iron tubs weigh several hundred pounds; we break them up in place with the room sealed, which is faster and safer than carrying one out whole.

What size tub fits my alcove?

Most Peninsula hall baths have a standard 60-inch alcove, 30 or 32 inches deep. Deeper soaking tubs that fit the same alcove are common; anything longer means moving a wall.
