Most tub to walk-in shower conversions in Snohomish County land between $12,000 and $25,000 installed. Staying in the tub footprint keeps you at the low end, moving plumbing and going heavy on tile and glass pushes the high end. That range is the local market, not a bid on your bathroom. The price rides on a few choices and on one layer nobody sees. We'll take them one at a time.
Size and whether the layout changes
A shower that stays in the tub footprint is simpler than one that grows into the room and moves plumbing. The more the layout shifts, the more framing and pipe work it takes, which is the biggest swing in the job.
Tile, glass, and fixtures
Tile choice covers a wide range, from a straightforward field tile to a full stone wall. Frameless glass costs more than a framed panel, and fixtures run from basic to spa-level. These are the picks you can dial up or down to fit the budget.
The waterproofing you cannot see
Under the tile there has to be a waterproof membrane, and it's the whole reason a shower stays dry. It takes time and a little material, which is exactly why a rushed crew skips it and the shower leaks in a year. We set that layer first, every time, and you can watch it go in.
Why the cheap shower gets expensive
A shower tiled over bad or missing waterproofing looks finished and fails inside the wall, and then you pay to tear it out and do it twice. The shower done right the first time is the one that actually costs less.
