There's a good chance the bathtub in your primary bathroom hasn't been filled in years. For a lot of Seattle-area homeowners, that unused tub is prime real estate — and converting it to a roomy walk-in shower is one of the highest-impact bathroom upgrades you can make. It opens up the space, modernizes the room, and makes daily life easier. Here's a straight-shooting look at what a tub-to-shower conversion costs, how it's actually done, and when it does (and doesn't) make sense.
Why Homeowners Are Making the Switch
Three reasons come up again and again when clients in Kent, Renton, and Bellevue ask us about a conversion. First, they never use the tub — showers are faster and the tub just collects dust. Second, aging in place: stepping over a tub wall gets harder over time, and a curbless walk-in shower removes that barrier entirely. Third, the look — a frameless-glass walk-in shower with modern tile instantly makes a dated bathroom feel current and larger.
What a Tub-to-Shower Conversion Costs
Cost depends almost entirely on which direction you go. A basic conversion — swapping the tub for a prefabricated acrylic shower unit — is the budget route and often lands in the low few-thousand-dollar range. A custom tiled walk-in shower with a waterproofed pan, full tile walls, frameless glass, a niche, and upgraded fixtures is a bigger investment, commonly running from the mid four figures up into five figures depending on tile choice, shower size, and whether any plumbing is relocated.
Here's the part most cost articles get wrong: the fixtures and glass aren't what drive the price. The waterproofing and tile work are. Doing those correctly — with the right membrane, a properly sloped pan, and skilled tile setting — is where the labor and the long-term value live. Extra costs to plan for include tub removal and disposal, and permits if plumbing is altered. We price every conversion line by line so you know exactly what you're paying for before we start.
The Process, Step by Step
A well-run conversion isn't just ripping out a tub and tiling a wall. Here's what actually happens when we do one right:
1. Demo & Inspection
We remove the old tub and surround and open the wet wall. This is when we can finally see the plumbing and framing — in older Puget Sound homes we often find aging galvanized supply lines or a drain that needs updating before the new shower goes in.
2. Plumbing & Drain
A tub drain and a shower drain aren't in the same place, so the drain is relocated and the valve is updated for a shower. If you want a curbless entry, the floor framing is adjusted so the pan can slope to a linear drain.
3. Waterproofing — the Step You Can't See
The pan is built and sloped, and a continuous waterproofing membrane is applied to the floor and walls. This is the single most important step in the whole project. Get it right and the shower lasts decades; cut a corner and you get leaks and rot behind the tile in a few years.
4. Tile, Glass & Fixtures
Wall and floor tile go in, grout cures, and then the glass, shower head, valve trim, and any niche or bench are installed. Cure time on waterproofing and grout is why a quality tiled conversion takes a couple of weeks — not a couple of days.
5. Inspection & Walkthrough
Where a permit applies, the work is inspected. Then we walk the finished shower with you, confirm everything drains and seals correctly, and hand it over clean.
The one detail that separates a good conversion from a costly one: waterproofing. Anyone can make tile look nice on day one. A shower that's still watertight in year ten is the product of the membrane and pan work hidden behind it — which is exactly why this isn't a job to hand to the lowest bidder.
Is It Worth It?
For most homeowners with an unused tub, yes — it's one of the best returns on comfort and daily livability in the whole house, and a modern walk-in shower is attractive to buyers.
There's one thing worth weighing: most buyers, especially families with young kids, like having at least one bathtub in the home. But if you're down to a single tub, you're not stuck choosing between "live with the dated tub" and "lose it entirely" — a tub can be just as much of a design upgrade as a shower. One of our favorite moves is a floor-to-ceiling tiled tub surround: we tile from the top of the tub all the way up to the ceiling, turning a plain builder-grade alcove into a striking, spa-like feature wall. You keep the tub buyers want and still get a fully modern, high-end look. So the real question usually isn't "tub or shower" — it's which mix fits your home. If you have more than one bathroom, converting the primary or a guest bath to a walk-in shower while giving another tub the tiled-surround treatment often gives you the best of both.
