The Victorians off D Street and the 1950s ranchers east of Petaluma Boulevard all remodel differently.

Why Sawyer Remodeling Is Petaluma’s Preferred Bathroom Remodeling Company

Petaluma homeowners tend to know their houses. They’ve dealt with the old pipes, the sloped floors, the bathroom that never dried out right. When they call us, they want a contractor who talks straight about scope, price, and schedule. That’s the work we do. Our Bathroom Remodeling team walks every job with the homeowner before quoting, so the written price reflects the actual house, not a generic template.
We run every Petaluma project under The Relay Standard: a live arrival time so you’re not burning a half-day waiting, photo updates at each milestone, and a digital invoice you pay from a link. The 365-Day Done Right Promise covers every remodel for a full year after we close out. If something isn’t right, we come back and make it right. That guarantee is in writing on every job we do in Petaluma.

Styles & brands we work with







Walk In Shower in Petaluma
A walk-in shower in Petaluma runs $4,500 to $12,000, and the final number depends on what’s behind the existing tub or shower. In older homes near downtown, that means planning for cast-iron drain lines and subfloor that may need replacing. In newer east-side construction, the job often goes faster because the framing and plumbing are already to modern code. Either way, we scope it line by line before you approve anything.
Converting a Tub to a Curbless Shower
Tub-to-shower conversions in Petaluma run $3,500 to $10,000. The big variable is drain relocation. Moving a drain line on a slab floor costs more than working over a crawlspace, and many Petaluma homes are built over crawlspaces, which helps. We’ll tell you exactly what your floor needs before the bid is final.
Frameless Glass and Waterproofing
Frameless glass shower enclosures are one of the most requested upgrades in Petaluma remodels. We install Schluter edge trim and proper waterproofing membrane behind every tile job, not just around the visible seams. That’s what keeps water out of the wall cavity in Petaluma’s damp winter months.
Bathroom Remodeling Companies in Petaluma

Choosing among bathroom remodeling companies in Petaluma usually comes down to one question: will the price hold? We put that concern to rest with a written, line-item price before any work begins. A full bathroom remodel in Petaluma runs $9,000 to $28,000, and when we quote you a number, that’s the number on the final invoice, unless you add scope in writing mid-project.
What a Full Remodel Covers
A full bathroom remodel in Petaluma means demo to the studs, new waterproofing, new fixtures, new tile or surround, new vanity, and new lighting. We pull permits through the City of Petaluma when electrical, plumbing, or structural changes are in the scope. Inspections get scheduled and passed before walls close.
Small Bathrooms and Powder Rooms
Small bathroom remodels in Petaluma run $5,000 to $12,000. These are usually the hall baths in older bungalows or the tight powder rooms off kitchens. The work moves faster, but the hidden conditions are the same: old drains, thin subfloor, maybe some unpermitted work from a previous owner. We price allowances for what we can’t see, and we explain every allowance before you sign.
Trusted Brands We Service in Petaluma
We install brands Petaluma homeowners ask for by name: Kohler and Toto fixtures, Cambria and Caesarstone vanity tops, KraftMaid and Wellborn cabinetry. We also work with newer construction brands that have a presence in Sonoma County, including Abodu and Dvele, when a bathroom remodel ties into a larger home project. You pick the materials from proven manufacturers, and we handle the install and the manufacturer warranty paperwork. No mystery suppliers, no off-brand substitutes.

AfterCommon Bathroom Remodeling Problems We See in Petaluma Homes
- Cast-iron drain lines that have outlived their lifespan. Homes built before 1960 in Petaluma often have original cast-iron plumbing that’s rusting from the inside out. We scope replacement during rough-in rather than burying it behind new tile and hoping.
- No subfloor under the original tile. A lot of pre-1960s Petaluma houses have tile set directly on 1×6 diagonal planks over the joists. That’s not a stable base for new tile. We add plywood underlayment to the scope and write it into the price before demo starts.
- Unpermitted prior work. We regularly find bathrooms where someone rerouted plumbing or added electrical without pulling permits. That can complicate a remodel because the City of Petaluma will want the new work brought to code. We handle the permit corrections and build the cost into the written estimate.
- Moisture and venting failures. Petaluma’s river-adjacent neighborhoods get damp winters, and an underpowered exhaust fan in an old bathroom leads to mold behind tile and around windows. Every remodel we do includes proper ventilation planning, not just a fan in the ceiling.

FAQs About Bathroom Remodeling in Petaluma
Yes, if you’re moving plumbing, relocating electrical, or changing framing. The City of Petaluma requires plan review and inspection sign-off for those changes. A like-for-like swap of a toilet or vanity usually doesn’t need a permit, but any remodel that opens walls and changes pipes or wiring does. We pull the permits, schedule the inspections, and make sure the work passes before we close the walls.
Because older Petaluma homes hide real conditions behind the walls: cast-iron drains that need replacing, missing subfloor under old tile, and unpermitted prior work that has to be corrected. A fixed bid that doesn’t include allowances for those hidden conditions becomes a change order fight. We write allowances into every older-home estimate so the price on the invoice matches the price you approved, even when demo uncovers something.
Most full bathroom remodels in Petaluma run two to four weeks from demo to punch list. Small bathrooms can finish in under two weeks. The schedule depends on permit review times and what the demo uncovers. We give you a written timeline at the start and photo updates as each phase completes.
Every line item, every material, every allowance for hidden conditions, the permit plan, the payment schedule, and the names of the crew who will be in your home. Our written scopes specify fixture models, tile specs, waterproofing method, and the 365-Day Done Right Promise. If a line isn’t in the scope, it isn’t in the price.
Yes. Tub-to-shower conversions in Petaluma run $3,500 to $10,000, and most of the work is done in a week or less. We handle the drain relocation, waterproofing, glass or curtain, and any framing changes. If your tub is original to a pre-1960s house, we’ll scope the drain line replacement at the same time so the new shower doesn’t sit on an old pipe.
