Curbless Shower Conversions in Berkeley Homes
What it takes to build a curbless shower in a Berkeley home: recessed floor framing, slope and drains, waterproofing, costs, and why raised foundations change the method.
Service
Swap an unused alcove tub for a walk-in shower in the same footprint.
Tub-to-shower conversion is the specific version of a shower conversion where the original alcove tub comes out and a tiled walk-in goes into the same footprint. Berkeley is full of candidates: 1905 to 1930 Craftsman and brown-shingle homes where the original cast-iron tub is still sitting on wood framing that has flexed under it for a century, and postwar homes in the flats with steel tubs nobody has bathed in for years. Cost typically lands at $16,000 to $28,000 for a straight swap with mid-grade tile and a standard glass panel. The recurring Berkeley surprise is what lives under the old tub: soft subfloor, corroded galvanized branches, sometimes the original lead drain bend. That is a known feature of this housing stock rather than an accident, so it belongs in the quote as a priced possibility from the start.
Only if it is the last tub in the house. Berkeley buyers skew toward families, and a home with no tub anywhere is a harder sell in Elmwood, Thousand Oaks, or Northbrae where the school draw is strongest. In a two-bath home, converting one tub to a walk-in shower is a net positive, most buyers prefer a modern shower in the bath they use daily. In a one-bath Craftsman, think carefully before giving up the tub, or plan the remodel around a shower-over-tub arrangement instead.
Most straight-swap conversions in Berkeley run $16,000 to $28,000. An alcove swap with mid-grade porcelain and a standard glass panel lands at $16,000 to $20,000. Premium tile, a niche, a frameless enclosure, or subfloor repair under the old tub pushes projects to $22,000 to $28,000. Curbless entries add $2,500 to $4,000 on a raised foundation.
Two of the clocks are not the crew's. The membrane cures on its own schedule before tile can be set on it, and custom glass is only fabricated once the finished tile has been measured. Around those, the variable is what comes out from under the old tub: rot or corroded branch lines in a pre-1930 house mean repair work before the floor goes back. Intricate tile patterns and inset niches add setting time.
The contractor breaks it up in place, cast iron is too heavy to carry out of a hundred-year-old bathroom whole, and hauls the pieces out with the rest of the demo debris. Disposal belongs inside the fixed price. Some owners of intact clawfoot tubs choose to sell or keep them instead, and that is worth deciding before demo day, refinished clawfoots have real resale value in the East Bay.
Mostly yes. The drain moves from the tub end to the center of the new shower, but the supply lines usually stay in the same wall. On Berkeley homes with post-and-pier foundations the plumber works from the crawl space, which keeps the work simple. Slab-on-grade homes, more common in West Berkeley and newer infill, need concrete cutting for the drain move, which adds $1,000 to $2,000.
