The unused tub is one of the most common bathroom design problems.
In a lot of Auburn homes, the primary bath tub never gets used — but it takes up the best wall in the room. A conversion reclaims that space.
When a tub becomes a place to set laundry baskets and bottles of dust, it's costing you the most valuable real estate in the bathroom. Replacing it with a properly designed walk-in shower changes how the room is used every day — better showers, more usable square footage, and a much cleaner look.
Most Auburn homeowners we work with want one or two of these upgrades together: a wider walk-in entry, a curbless or low-threshold floor, a built-in bench, a hidden niche, and clear frameless glass. We tailor the combination to the room and to how you actually use the bathroom.
Conversions are also one of the smarter moves for staying put as life changes. A well-designed low-step shower works for kids today and aging knees later — without ever looking like a hospital.

More than swapping fixtures.
- Demo of the tub, surround, and any compromised subfloor
- Plumbing rework — moving the drain, valve, and supply lines for the new shower layout
- Bonded waterproofing system over the new shower pan and walls
- Tile installation, glass enclosure, and trim out
- New ventilation, lighting, and outlets where they make sense
- Final walkthrough and sealing
Three common Auburn conversion layouts.
Footprint-for-footprint replacement. The simplest and most common option — the new shower stays inside the original tub footprint. Plumbing changes are contained, and the room reads cleaner immediately.
Extended walk-in. When the wall opposite the tub allows it, we push the shower a foot or two further into the room for a more comfortable bathing space and a bench. This is our most-requested option in primary bathrooms.
Curbless wet-room. The shower opens directly into the rest of the bathroom with no curb, sloped to a linear drain. Stunning, accessible, and the most involved on the waterproofing side.
The hidden details that make a conversion last.
Subfloor condition. Tubs hide a lot. We often find compromised subfloor under old fiberglass tubs — that gets replaced or reinforced before any new waterproofing goes down.
Drain relocation. Moving a drain a few inches changes the joist and pipe layout below. We map that during design so demo day doesn't surprise anyone.
Vent and light upgrades. Many older Auburn bathrooms vent into the attic instead of outside, or have no vent at all. A conversion is the right time to fix it, along with adding shower-rated lighting if needed.
The systems behind a conversion that lasts.
Specific brands and methods. The materials decide whether the shower performs in five years.
Subfloor + framing
Conversions often expose compromised subfloor under the old tub. Our default repair: replace down to the joists with 3/4″ tongue-and-groove plywood fastened with construction adhesive plus screws. We reinforce or sister joists where rot has reduced bearing capacity before any new pan goes down.
Waterproofing
Schluter Kerdi bonded sheet membrane on the walls and pan, lapped properly into the drain flange. For curbless conversions, Schluter Kerdi-Shower ST pre-sloped trays sized to the new opening, set into a recessed subfloor so the floor surface stays continuous.
Drains + thresholds
Schluter Kerdi-Linelinear drains for modern conversions; standard 2″ center drains where the layout calls for it. Threshold options range from a clean curbless approach to a 1-2″ low-threshold built up with mortar-bed and tile, depending on subfloor condition and accessibility needs.
Plumbing rework
We move the valve, rough-in, and drain to fit the new shower layout. Where original galvanized supply is encountered, we replace with PEX up to the manifold while the wall is already open — it's the right time, and it avoids a callback five years later.
Tile + fixtures
Stone-look porcelain in 12×24 or 24×48 large-format on walls, with a smaller mosaic on the shower floor for slip resistance. Brizo, higher-tier Kohler, or California Faucets for valves and trim — replaceable cartridges, solid brass. Frameless 3/8″ or 1/2″ low-iron glass with CRL hinges.
The mistakes that turn a conversion into a callback.
Conversions fail in predictable ways. Skipping any of these is what causes a homeowner to call a different contractor two years later.
- Subfloor not assessed at demo. If the old tub leaked even slowly, the wood under it is usually compromised — and any new waterproofing on a soft subfloor moves and fails.
- Drain offset improperly relocated. A drain moved a few inches needs the joist layout below to be planned for it. Routing through a joist instead of around it weakens framing and risks leaks.
- Curbless threshold without a recessed subfloor. If the shower floor isn't recessed below the surrounding floor, water has nowhere to slope to and finds its way out.
- Original supply lines kept in place. Galvanized pipes lose internal diameter over decades. Patching new shower work onto failing supply just delays the next problem.
- Vent fan vented into the attic. A conversion is the right time to vent the fan exterior — doing it later means opening the wall again.
Decisions that make a conversion feel intentional.
A conversion can either look like the bathroom was always going to have a walk-in shower, or it can read as a retrofit. The difference is in the details below.
Threshold style
Curbless is the cleanest visual — the shower floor is continuous with the bathroom floor, sloped to a linear drain. It's the right call for accessibility and for primary baths where the bathroom is large enough to absorb the recessed subfloor work. Low-threshold(a 1–2″ tile-clad curb) is more forgiving on older subfloors and reads modern without the structural complexity. We almost never recommend a traditional 4–6″ curb on a new conversion — it dates the project immediately.
Footprint decisions
The simplest conversion stays inside the original tub footprint. The most-requested in Auburn primary baths extends the shower a foot or two into the room, which earns space for a built-in bench and a more generous showering experience. The most ambitious is the wet-room conversion — the shower opens directly into the rest of the bathroom with no door at all, requiring the most careful waterproofing. We talk through all three at consultation.
Drain placement
Linear back-wall drains (against the back tile wall) are the cleanest visual — the drain virtually disappears. Linear center drains are easier on a retrofit because they hit the existing tub drain location; less elegant visually, just as functional. Round center drains are the traditional option, fine in a curbed shower; rarely the right call in a curbless or low-threshold build because they require a four-way slope.
Niche placement after conversion
Conversions open up new niche locations because the wall that held the tub fixtures is now usable. We typically place the primary niche on the wall opposite the showerhead, at chest-to-shoulder height, sized 12×24 or 24×24 to align with tile modules. A small secondary niche for body wash or razor at lower height works well in showers with a bench.
Bench sizing + placement
An end-of-shower bench is the most practical — 17″ tall, 17–18″ deep, and the full width of the shower if the layout allows. Floating benches (cantilevered off the back wall) read more modern but require careful waterproofing detailing. In smaller conversions where a bench would crowd the shower, we recommend skipping it entirely.
Glass design
The full-enclosure (three walls + door) layout contains spray and reads traditional. The single-panel + walk-in entry layout (one fixed glass panel, no door) reads modern and feels more open — but requires careful slope and a taller fixed panel to keep water in the shower. Frameless 3/8″ or 1/2″ low-iron glass either way; we avoid framed enclosures, which date a conversion.
Style continuity with the rest of the bathroom
A conversion is the right time to either match the existing bathroom's voice (so the new shower feels original) or reset it (when the rest of the bathroom is also dated and the homeowner is open to updating it later). What's worse than either: an abrupt finish break at the threshold — sage stone shower meeting beige builder tile floor reads as a retrofit.
