If your Seattle bathroom still has the original tub from when the house was built, you're in the majority. And if no one in the household has actually taken a bath in the last year, you're in the same boat as most of our customers when they call.
Tub-to-shower conversion is one of the most common projects we run in the Seattle metro. The footprint already exists, the plumbing is already there, and converting the space rarely requires a permit. The result is dramatic: the dated, hard-to-clean, hard-to-step-into tub becomes a clean low-threshold walk-in shower in about a day of work.
This guide walks through what's actually involved — what gets removed, what gets reused, what surprises can come up, and what changes the final price.
Is your bathroom a good candidate?
Most are. The classic candidate is the alcove tub — three walls around a standard 60" x 32" tub with the drain at one end. That footprint is essentially a walk-in shower with a tub installed in it.
Less straightforward, but still routine:
- Drop-in tub in a tile deck. The deck has to be demoed, but the rough plumbing usually still works.
- Corner tub. Often a 60" x 60" footprint that becomes a generous corner shower.
- Garden tub with a separate shower. If you have both, removing the tub gives you space for a much bigger walk-in shower or, in some bathrooms, a double-bowl vanity expansion.
The only situation that gets complicated is when the bathroom only has a tub and no separate shower elsewhere in the home — in which case we'll usually still recommend the conversion (the walk-in shower is the daily-use fixture), but we'll talk through resale considerations.
What demo day actually looks like
Protect
Floors, vanity, and door frame get covered. Path from front door to bathroom is protected.
Demo
Tub apron cut, surround removed, tub disconnected and hauled out. Subfloor inspected.
Plumb
Drain converted from tub to shower spec. Supply lines checked. Valve replaced if needed.
Install
Shower pan set, walls panelized with Bellatone, door and hardware mounted. Cleanup.
Most standard tub-to-shower conversions can be completed quickly — often in as little as one day after materials and measurements are ready. Bathrooms that need subfloor repair, drain relocation, or galvanized line replacement may run into a second day.
The three things that can move the price
1. Subfloor surprises
The single most common adjustment. Older Seattle and Kirkland tubs have been slowly leaking around the apron for decades. The leak is usually small enough that no one notices, but the subfloor under the tub can be soft or rotted by the time we pull the tub out. We can't see it until demo.
Our practice: we quote a base price and a clearly-disclosed subfloor allowance in the estimate, and we show the homeowner the condition before doing any repair work. There's no surprise invoice.
2. Drain relocation
Tubs drain at the end. Walk-in showers usually drain in the center. If the new design moves the drain, the plumber has to access it from below — easy if there's a crawlspace, more involved on a slab. Most Seattle homes have crawlspaces or unfinished basements below the primary bath, which keeps this affordable.
3. Aging supply lines
Pre-1980 homes in Magnolia, Wallingford, Capitol Hill, Madrona, and many older Eastside neighborhoods often still have some galvanized water lines. While the wall is open, replacing the visible run with PEX or copper is cheap insurance against a future leak inside a finished wall.

Resale: does removing the tub hurt the home's value?
This used to be the standard real-estate-agent warning. It's largely outdated. As long as the home has at least one tub somewhere — usually in a hall or guest bath, often used for the occasional kid bath or staged for resale — converting the primary tub to a walk-in shower is now considered a value upgrade in most Seattle neighborhoods.
Where the old rule still applies: a one-bathroom home with no other tub anywhere on the property. In that case, families with young children may prefer the option, and removing the only tub could narrow the buyer pool.
Design decisions that matter most
Threshold height
The whole point of converting is usually to lower the step-in. Standard low-threshold curbs are 2"–4" tall — much easier than the 14"–18" tub wall. Curbless (zero-threshold) builds are the safest option but require subfloor work to drop the drain and pitch the floor; they cost more.
Door style
The three common choices:
- No door (walk-in entry). Cleanest look, easiest entry, but the bathroom needs to be large enough to keep water in.
- Semi-frameless glass door. The everyday standard. Affordable, looks clean, easy to use.
- Frameless glass door. The premium look. Heavier hardware, beautiful in person, adds about $800–$1,800 over semi-frameless.
Bench and accessories
Almost every aging-in-place shower benefits from a permanent built-in bench. Add discreet grab bars in the same finish as your hardware and they read as design features, not safety equipment. For the full safety playbook see Aging-in-Place Shower Remodels.
Cost expectation
A standard alcove tub-to-shower conversion in the Seattle metro typically runs in the premium-acrylic tier — $8,000 to $14,000 installed, depending on options. Our Aging-in-Place Special starts around $9,990 for qualifying standard conversions with Bellatone wall panels and a lifetime material warranty.
