We serve every corner of Petaluma, from the west side’s mid-century ranches to the Victorian-era homes east of downtown. If you’re planning a bathroom remodel here, you need a contractor who’s already seen what’s behind the walls in this city’s housing stock. That’s why our estimates start with a walkthrough, not a photo.
Why Mason Remodeling Is Petaluma’s Preferred Bathroom Remodeling Company

A live person answers our phone 24 hours a day, every day, including weekends and holidays.
Petaluma homeowners often tell us the same thing: they put off remodeling because they’re not sure who they can trust inside their home. We settle that before the first tool is unpacked. You get names, photos, a clean marked uniform, a photo ID badge at the door, and a written guarantee with terms stated plainly.
Styles & brands we work with
Small Bathroom Remodel in Petaluma
A Small Bathroom Remodel in Petaluma is the smart move when your guest bath or hall bath is tired but functional, and you want to refresh it without reworking the entire floor plan. These jobs usually involve a new vanity, updated fixtures, fresh tile, better lighting, and a new toilet, all working within the existing footprint. In Petaluma, a small bathroom remodel runs $5,000 to $12,000, with the biggest variables being tile scope, plumbing fixture quality, and whether the existing subfloor is sound.
Hall Bath Refresh
Petitions for hall baths dominate our small remodel work in Petaluma because these rooms take the most daily use. We typically replace the tub surround, swap in a Kohler or Moen fixture set, install a KraftMaid vanity, and add a solid-surface top. Most of these jobs stay under $9,000 and wrap in two to three weeks once the permit clears.
Guest Bath Update
For guest baths that only see occasional use, we focus on value: a new vanity, fresh paint, updated hardware, and maybe reglazing the existing tub rather than replacing it. You’ll spend $5,000 to $7,000 and get a clean, current room that doesn’t embarrass you when company stays over.
Shower Remodel in Petaluma
A Shower Remodel in Petaluma ranges from $3,000 for a straightforward shower replacement to $12,000 for a custom walk-in with frameless glass. The work varies a lot depending on your home’s era. In many of Petaluma’s 1950s and 1960s ranches, the slab floor means moving a shower drain is far more involved than in a home with a raised foundation. We factor that into your written price before we start, so you never get hit with a surprise trenching bill after demolition begins.
Walk-In Shower Conversion
Converting an alcove tub to a walk-in shower is the most popular shower remodel we do in Petaluma, running $3,500 to $10,000 for the conversion itself. The complication in this city is drainage: slab-on-grade construction means we often have to saw-cut concrete and reroute the drain line to get the right slope. We’ll tell you on day one whether your specific home needs that, and the cost is in the written estimate.
Frameless Glass Enclosures
Frameless glass enclosures are the finish that makes a new shower feel truly custom. We measure after tile is set so the glass fits precisely, and we use specification-grade hardware that won’t sag or collect water stains the way cheaper fittings do. Expect to budget $1,500 to $3,500 for the glass on top of the base shower work.
Trusted Brands We Service in Petaluma
Our team installs and services residential construction products from brands including Abodu and Dvele when Petaluma homeowners want panelized or prefab components integrated into a remodel. We also regularly work with KraftMaid, Wellborn, Cambria, Silestone, Caesarstone, Kohler, Moen, Toto, and Grohe. When you choose a vanity, fixture, or surface from these manufacturers, we can quote it, order it, and coordinate delivery to your Petaluma home without forcing you to chase down a supplier yourself.

AfterCommon Bathroom Remodeling Problems We See in Petaluma Homes
- Slab-on-grade drain work. Mid-century Petaluma homes often sit on concrete slabs, and moving a shower drain means trenching through that slab. Contractors who bid from photos miss this, and the change order arrives after the walls are open.
- Permit backlog at the City of Petaluma building department. Plan review can stretch longer than homeowners expect, especially in the spring and summer building season. We build that timeline into your schedule from the start and call the department on your behalf.
- Uncapped plumbing from old tub-to-shower conversions. We have opened up finished walls in Petaluma to find pipes that were never properly capped behind the tile. That fails rough-in inspection and means tearing out work you already paid for.
- Victorian-era joist spacing under upstairs baths. Homes near downtown Petaluma often have older framing that doesn’t meet today’s deflection standards for tile. We check joist spacing and subfloor depth before we commit to a tile spec, and we’ll tell you if you need subfloor reinforcement.

We recently remodeled a hall bathroom in a mid-century ranch off Maria Drive, converting a cramped alcove tub into a walk-in shower. The slab-on-grade construction meant our crew had to trench the concrete to reroute the drain for the new rough-in, then build up the subfloor to match the existing hallway floor height. The job finished with a KraftMaid vanity and Kohler fixtures, and the final punch list cleared after inspection sign-off.

FAQs About Bathroom Remodeling in Petaluma
Fixture swaps like a new toilet, vanity, or faucet generally don’t require a permit in Petaluma, but any work that moves plumbing drains or supply lines does. When you move a toilet, shower drain, or tub location, you’ll need a plumbing permit from the City of Petaluma, and likely a building permit if walls or tile backing come out. We handle the permit paperwork for every job where one is required. Call (803) 680-2547 and we’ll tell you during the estimate whether your scope triggers a permit.
A typical bathroom remodel in Petaluma costs $9,000 to $28,000, with the biggest drivers being tile square footage, vanity and fixture grade, and whether your home’s concrete slab needs trenching for drain relocation. A small bathroom remodel in a home with a raised foundation can be done for $5,000 to $12,000. For an exact figure on your bathroom, call (803) 680-2547. The estimate is free and it’s in writing.
Your written scope should list exactly which fixtures and materials are included by name or model number, which walls are coming out and which stay, where plumbing is moving if at all, what tile and trim are specified, and the total price for all of it, plus the payment schedule and permit responsibility. Ours includes all of that, and the price doesn’t change because we missed something in the estimate. That’s the written guarantee, stated in plain terms.
A small bathroom remodel in Petaluma usually runs two to three weeks once the permit clears; a full gut remodel runs four to six weeks. The biggest variable in this city is the City of Petaluma plan-review timeline, which can add two to four weeks before we open a wall. We schedule your start around that real timeline, not an optimistic one. Call (803) 680-2547 and we’ll map out a calendar for your specific scope.
Yes, and we do it regularly. The main complication is that many mid-century Petaluma homes sit on slab-on-grade concrete, so moving the shower drain means trenching through the slab. We’ll inspect your floor during the estimate and tell you whether your conversion needs that work, and the cost is in your written price. The conversion itself runs $3,500 to $10,000 in this market.
