What “walk-in” means in practice

A walk-in shower is a shower you step into without climbing over a tub wall. It can have a low curb, a curbless entry, a door, or just a fixed glass panel. On the Peninsula most of them replace a 60-inch tub in a hall bath, and the rest replace a cramped fiberglass stall in a primary bath.

What makes a walk-in shower last is not the tile but what is behind it: the pan, the slope, the waterproofing and the drain.

How we build one

  1. Demolition to the studs at the shower walls, with the room sealed and the floor protected from the front door in.
  2. Framing and blocking: we straighten the walls, frame niches and add blocking for grab bars, glass and a bench, even if you add the bars years later.
  3. Plumbing: a new pressure-balance or thermostatic valve at shower height, usually with a handheld on a slide bar, and a center or linear drain.
  4. Pan and waterproofing: a sloped mortar bed or a pre-sloped tray, then a bonded membrane up the walls. We flood-test the pan for 24 hours before any tile goes on.
  5. Tile: porcelain wall tile, a smaller-format or mosaic floor for grip, sealed grout and metal edge trims.
  6. Glass: measured after tile, installed about a week later. A curtain rod stays up until then.

What moves the price

  • Where the drain goes. Reusing the tub drain is the low end. A centered or linear drain is the middle. A curbless recess is the high end.
  • Glass. A fixed panel costs less than a hinged door; glass to the ceiling, for a steam-ready shower, costs more again.
  • Tile size and layout. Large-format wall tile and a herringbone floor take more labor than the tile itself costs.
  • Slab or crawlspace. Under a ranch, a drain move is a day of plumbing. In an Eichler it means scanning and saw-cutting the slab.

Walk-in shower questions

What size does a walk-in shower need to be?

A 60-by-30-inch tub alcove makes a comfortable walk-in shower with a fixed glass panel and no door. Anything under about 36 by 36 inches needs a door to keep water in.

Do I need a curb?

No, but going curbless means recessing the floor so it slopes to the drain, which adds days and cost. A low curb of two to four inches is the usual choice in a hall bath.

Do I need a permit for a walk-in shower?

When the drain or valve moves, yes. We pull it, schedule the rough plumbing and shower pan inspections, and attend them.

How long until I can use it?

About five working days for a tiled shower in an old tub alcove, seven to ten for curbless. Glass is measured after tile and goes in about a week later.
