Tub-to-shower conversions, curbless walk-ins and custom tile showers for Lake Oswego homes. We rebuild the parts that fail — the waterproofing, the drain, the valve — and flood-test every pan before a single tile goes up.
Most failed showers we tear out didn’t fail at the tile. They failed at the pan, the seams or the valve — water that got behind the surface years ago and quietly rotted the framing. We use a bonded waterproofing membrane, slope the pan correctly, flood-test it for 24 hours, and only then tile.
Tub-to-shower conversions, curbless walk-ins, custom tile and frameless glass. Demolition, supply and drain work, waterproofing, tile and enclosure under one contract. Planning the whole room? See bathroom remodeling in Lake Oswego.
An unused alcove tub comes out and the full width becomes a walk-in shower — new drain, new valve, new waterproofing.
Zero-threshold entries with a recessed pan and linear drain, so the floor runs flat from the door to the shower head.
Bonded membrane over a sloped bed, sealed corners and flange, water-tested before a single tile is set.
Templated frameless and semi-frameless enclosures, thermostatic valves, rain heads, hand showers and body sprays.
We check the floor framing, the drain location and the existing valve, and tell you whether a curbless entry, a wider footprint or a bench is realistic in your space.
Tile, glass, valve and drain selections, plus the plumbing permit from the City of Lake Oswego when the valve or drain moves.
Demolition, new supply and drain, a bonded waterproofing system flood-tested for 24 hours, then tile, glass and trim — with the inspection scheduled by us.
Lake Oswego homeowners choose Serden because every shower is waterproofed, flood-tested and inspected before the tile goes up.
Great experience working with this company. They were professional, responsive, and the quality of their work was solid. They even took the time to treat me to lunch and go over the project details, which I appreciated. Would recommend.
The SERDEN Group did a complete remodel of our two upstairs bathrooms. Every step of the way Dennis, and his team, were communicative, kind, timely, and productive. They worked diligently, caring about the impact of having workers in your home. Everyone was friendly and attended to our creative ideas for the bathrooms. In the end we have two amazing new bathrooms. Our family is grateful for SERDEN and are wonderfully reminded daily of their excellent work. Thank you!
I recently hired Serden Group for a full kitchen and bathroom remodel, and I couldn't be happier with the results! From start to finish, the team was professional, reliable, and detail-oriented. The quality of their work is outstanding — everything from the tile installation to the cabinetry and finishes looks beautiful and well-crafted. They completed the project on time and within budget, which is rare to find these days. I highly recommend Serden Group to anyone looking for top-quality remodeling work. They truly exceeded my expectations!
I had a very pleasant experience with SERDEN GROUP company. They remodeled my bathroom, and I am completely satisfied with the result. Fast and high-quality work. Denis answered all of my questions, suggested great solutions for the renovation, and delivered everything he promised. I 100% recommend them.
Had the pleasure to work with this team on a project for one of their clients. They followed through with every request from start to finish and we can proudly say that, they really put their best foot forward with all their work. Our team would love to continue to work together for future jobs!

The choices that decide how long a shower lasts are made before the tile is picked. Here is how we approach them in Lake Oswego homes.
A shower remodel in Lake Oswego, OR typically costs $26,000–$45,000 in 2026 for a tub-to-shower conversion with a widened footprint. Tile walk-ins in the existing space start around $15,000, and curbless showers run $45,000 or more. Most take 2–4 weeks. Moving a valve or drain requires a City of Lake Oswego plumbing permit.
Some installers here sell one-day acrylic liners from a few thousand dollars. They cover the old surround rather than fix it.
Almost every Lake Oswego home is wood-framed over a crawlspace or basement, so a zero-threshold entry means lowering the floor, not just leaving out a curb.
The most common shower project we price. Whether removing the only tub hurts resale depends on the house.
Older showers here hide the most. Expect repairs before the new work begins.
| Scope | Typical cost | Timeline |
|---|---|---|
| Acrylic liner over existing | $4K–$12K | 1–3 days |
| Tile walk-in, same footprint | $15K–$26K | 2–3 weeks |
| Tub-to-shower, widened | $26K–$45K | 3–4 weeks |
| Curbless with floor work | $45K+ | 3–5 weeks |
Relocating or replacing an in-wall valve, moving a drain, or adding circuits for a heated floor or lighting needs a permit. In Lake Oswego the plumbing and electrical permits are issued by the city. We file them and schedule inspections.
Retiling over a sound pan with the valve and drain left in place generally doesn’t. We confirm with the city before telling you a permit isn’t needed.
From First Addition and Old Town to Lake Grove, Westlake, Palisades and Mountain Park — plus West Linn, Dunthorpe and Tualatin. We handle City of Lake Oswego plumbing permits whenever a valve or drain moves. Our Lake Oswego office is at 333 S State St, Lake Oswego, OR 97034 — design consultations by appointment.
