AfterFast, Reliable Bathroom Remodeling Across Petaluma
A bathroom remodel in Petaluma typically runs $9,000 – $28,000, and the final number depends on what’s behind your walls, not just what you can see. West of US-101, we’re usually opening up a balloon-frame Victorian or Edwardian with wood-lath plaster and a perimeter-wall foundation that may never have been bolted. East of the freeway, we’re more likely working in a post-WWII ranch on slab-on-grade. Both are jobs we know well, and both start with the same thing: a written price before any work begins. Call (936) 259-2607 and we’ll walk your bathroom with you.
Why Penhallow Remodeling Is Petaluma’s Preferred Bathroom Remodeling Company
We’ve spent enough time in Petaluma basements and crawl spaces to know the difference between a house near McNear Park and one out by Lucchesi Park. The west side homes need a different kind of attention than the east side tracts, and our pricing reflects that honestly. You won’t get a ballpark number over the phone and a different figure at your door. You’ll get a written quote after we look at your actual walls, floor, and foundation.
Our crews are background-checked and uniformed, so the people who walk into your home are the ones you know by name. Trevor Nash, who leads our remodeling work, has a habit of explaining what “substrate” means before asking you to sign anything. Every job includes the 365-Day Done Right Promise, in writing: if something fails inside the guarantee period, we come back and fix it at no charge. That’s the Kingswell standard, and it’s been operating since 2004.
When you call, a live person answers. Not a voicemail maze, not a callback window. That matters when you’re standing in a gutted bathroom on a Tuesday afternoon with a question about your Kohler rough-in.
Bathroom Remodeling Contractor in Petaluma
A bathroom remodeling contractor in Petaluma handles more than swapping a vanity and slapping on new tile. West of US-101 especially, the job starts with figuring out what’s behind the old plaster: framing condition, foundation bolting, electrical wiring roughness. We pull permits when they’re required, coordinate the rough-in with a licensed plumber and electrician, and make sure the waterproofing is done right before any tile goes up.
Full Bathroom Remodeling
A full remodel means the room gets stripped to the studs, and in a Petaluma west-side home that’s a bigger deal than in a newer build. You’re likely looking at shear-wall additions, cripple-wall bolting, and an upgrade from knob-and-tube to grounded wiring. We write those costs into the contract as allowances, then price anything we find in the walls in writing before we touch it.
Small Bathroom Remodeling
Smaller bathrooms in Petaluma run $5,000 – $12,000, and we often work in half-baths near Helen Putnam Plaza or compact second baths in east-side ranches. The scope stays tight: new tile, a smaller vanity, updated fixtures, maybe a new toilet and light. The same written-price rule applies.
Walk In Shower in Petaluma
A walk in shower in Petaluma runs $4,500 – $12,000, and it’s one of the projects we handle most often for west-side Victorians where a clawfoot tub is wasting space nobody uses. We remove the old tub or shower, build a proper cement board substrate, water-proof it correctly, and install either a frameless glass enclosure or a tiled surround, depending on what fits your room.
Walk-In Shower Installation
The core work here is waterproofing. Petaluma’s older homes have original wood-lath plaster that was never intended to hold a wet environment indefinitely. We install a modern substrate and membrane system before any tile is set, so the shower pan doesn’t fail the first time the house moves.
Tub-to-Shower Conversion
A tub-to-shower conversion in Petaluma runs $3,500 – $10,000. For an older west-side bathroom, this often means addressing the same structural issues as a full remodel: unbolted perimeter framing, undersized floor joists, and old supply lines. We inspect first, price second, and never start demolition before you’ve seen the numbers in writing.
Trusted Brands We Service in Petaluma
We stock and install material from brands that carry their own warranties alongside ours: KraftMaid and Wellborn cabinetry, Kohler and Moen fixtures, and Cambria, Silestone, and Caesarstone countertops. For Petaluma homeowners, that means a quartz top with a manufacturer’s lifetime warranty, not a supply-yard special we wouldn’t put in our own bathroom. We order local parts daily and can usually get specialty pieces to Petaluma in one to two weeks. If you’ve been looking at factory-built panel systems from companies like Dvele or Abodu, we can talk through how conventional site-built remodeling compares, especially in a west-side heritage home where those systems rarely pencil out.
Common Bathroom Remodeling Problems We See in Petaluma Homes
- Knob-and-tube wiring hidden behind the tub wall. Older west-side homes off Keller Street and around the downtown grid were wired before drywall existed. Once the wall is open, the inspector will require a grounding upgrade, so we write that into the allowance up front.
- Failed waterproofing under original tile. The wood-lath plaster in pre-1920s homes absorbs moisture and moves with the seasons. New tile over that old surface fails fast. We remove it, install a proper substrate, and warranty the work in writing.
- Unbolted perimeter foundations triggering scope changes. Petaluma inspectors routinely flag cripple walls that were never bolted when a bathroom permit opens the walls. That’s a structural fix no one wants to learn about mid-project. We inspect for it before quoting.
- Winds off the Petaluma Gap affecting ventilation runs. Homes near the mouth of the Petaluma Gap get more afternoon marine wind than Santa Rosa or Napa. A bathroom exhaust fan routed to a gable end in a windy area needs proper backdraft dampers or it’ll whistle and short-cycle. It’s a small thing until it isn’t.

FAQs About Bathroom Remodeling in Petaluma
West-side Victorians and Edwardians from the 1870s – 1920s are balloon-frame with wood-lath plaster interiors and perimeter-wall foundations that typically need shear-wall additions and cripple-wall bolting before any remodel can pass inspection. East-side post-WWII ranches sit on slab-on-grade or raised foundations with drywall and grounded electric, so the same-looking bathroom costs less because the walls don’t hide structural work. If you’re west of 101, expect the top half of our pricing range. Call (936) 259-2607 for an exact quote.
Possibly, and more likely if you’re west of US-101 or near downtown. Once a permit opens your walls, the inspector can flag unbolted perimeter foundations, and Petaluma’s building department may require a structural engineer’s evaluation before work continues. We coordinate that with a licensed engineer, and the cost is written into your quote as an allowance, not a surprise.
A full bathroom remodel runs $9,000 – $28,000. Small bathrooms run $5,000 – $12,000. Walk-in shower installation runs $4,500 – $12,000, and shower replacement runs $3,000 – $8,500. The variable is what’s behind your walls: foundation bolting, wiring roughness, and waterproofing condition. Call (936) 259-2607 and we’ll give you a written number.
We stop, document what we found, and write a change order with a fixed price before we touch another stud. On a 1908 Edwardian off Keller Street, our crew found knob-and-tube wiring and unbolted framing behind the tub. We pulled a structural engineer in, priced shear-wall additions and cripple-wall bolting in writing, and the homeowner signed before we proceeded. No mid-job surprise bills, ever.
Yes, if you’re moving plumbing, changing the drain location, or opening load-bearing walls, a permit is required in Petaluma. We pull the permit as part of the job, and we schedule inspections so the work signs off on the first walk-through whenever possible. Some cosmetic work like swapping a vanity or replacing a toilet doesn’t require one, and we’ll tell you which applies to your project.
