Fast, Reliable Bathroom Remodeling Across Sebastopol

That price range covers everything from a straightforward tub-to-shower conversion to a complete gut and rebuild with custom tile, a walk-in shower, and a new vanity. Penhallow Remodeling gives you a written price before any work starts, so you know the real number up front. Call (936) 259-2607 to schedule your free estimate with Trevor Nash and the team.

We know Sebastopol’s houses because we work on them week in and week out. Not just the pretty Victorians on Florence Avenue, but the 1970s ranchers off Bodega Avenue, the mid-century homes near the Barlow, and the owner-built straw bale and timber frame places out toward Occidental Road. Every one of them has quirks that a generic remodeler misses. Our crew lives with the same fog, the same clay soil, and the same permitting office you do, and that shows up in the work.

Why Penhallow Remodeling Is Sebastopol’s Preferred Bathroom Remodeling Company

Sebastopol homeowners don’t want a contractor who writes a number on a napkin and revises it after demo day. That’s exactly the kind of experience that lands you in the Bathroom Remodeling market searching for someone who won’t do it again. Penhallow Remodeling has built its name in Sonoma County on one simple practice: the price we put in writing before the first tile is pulled is the price on your final invoice. No change orders, no mystery line items. Trevor Nash runs every Sebastopol project under the Kingswell standard established in 2004, which means a written guarantee comes with every job. The 365-Day Done Right Promise is explicit: if the work fails inside a year, we come back and fix it at no charge. Not pro-rated, not “after we check the fine print.” We come back.

Our Sebastopol customers also value that a live person answers the phone 24/7. When you call at 7 a.m. because you realized the powder room floor feels soft, you get a real person, not an answering service. The technicians who show up at your door are background-checked and uniformed, and you know their name before they walk in. In Sebastopol specifically, our team has handled bathroom projects on slabs built over former orchard land, in flood-zone parcels near the Laguna, and in older wood-frame homes where fog moisture has been creeping through the walls for thirty years. Local knowledge isn’t a marketing phrase here; it’s how we write an accurate quote the first time.

Bathroom Renovation in Sebastopol

A bathroom renovation in Sebastopol means more than swapping a tub for a shower. It means stripping the room to its framing (or, in many Sebastopol homes built on former apple orchard land, to a slab that has dealt with compacted clay and residual root systems for decades), correcting any water damage from the marine fog that sits over this town most mornings, and rebuilding the space with assemblies that actually hold up to Sonoma County’s chronic moisture. A full renovation in Sebastopol typically runs $9,000 – $28,000. The range exists because a 50-square-foot hall bath with a new tub, tile surround, and vanity lands at the low end, while a primary bath with a curbless walk-in shower, heated floor, custom cabinetry, and a relocated toilet line lands at the top.

Locally scoped permits and flood-plain realities

Before we quote a renovation, we run a FEMA flood zone determination on your parcel. A meaningful share of in-town and west-side Sebastopol parcels sit inside the Laguna de Santa Rosa floodplain, and if your bathroom falls in an AE or X-shaded zone, the finished floor may need to be raised 12 – 24 inches above grade. That changes the entry steps, any garage slab transitions, and the utility rough-ins. We resolve this in scope before a quote is issued, not after your old bathroom is already gutted.

What gets replaced, not just patched

A renovation gives us the chance to replace what’s actually failing: the rotten subfloor, the unvented wall cavity holding moisture, the undersized exhaust fan that has let fog-born condensation sit on your drywall for years. We specify Kohler and Moen fixtures, Schluter shower assemblies, and cement board substrate (the moisture-resistant layer behind your tile) so the new bathroom doesn’t repeat the old one’s problems.

Small Bathroom Remodel in Sebastopol

A small bathroom remodel in Sebastopol usually covers a powder room, a hall bath under 40 square feet, or a compact primary bath and runs $5,000 – $12,000. That range assumes we keep the toilet where it is, refresh the floor and wall finishes, and replace the vanity, fixtures, and lighting. Small doesn’t mean simple in this town, and on former orchard parcels the cost can nudge higher if the slab under the bath has settled or the original rough-in wasn’t built to current flood-plain expectations. We price this honestly before we start.

What the money goes toward

In a small bath, the largest line items are the shower or tub fixture, the tile work, and any subfloor repair. Sebastopol’s fog and winter rain mean a small bath with a poorly sealed window or an unvented shower can hide real rot behind the drywall, and that’s the difference between a $5,000 cosmetic refresh and a $9,000 repair-and-refinish. We open the wall, show you what’s there, and let you decide with a written price in hand.

Curbless and space-smart layouts

Many Sebastopol homeowners want the small bath to feel larger without moving walls. A curbless walk-in shower, a wall-mount vanity, and a lighter tile palette can do that. We’ve installed frameless glass enclosures in tight Sebastopol baths that opened the room visually without changing the footprint, and that work typically falls in the $4,500 – $12,000 range for the shower portion depending on glass and tile.

Trusted Brands We Service in Sebastopol

We install materials from brands that stand behind their products with real warranties: Kohler and Moen fixtures, Schluter waterproofing systems, and American-made cabinetry lines like KraftMaid and Wellborn. Countertop runs include Cambria and Silestone quartz, which carry their own manufacturer warranties alongside our 365-Day Done Right Promise. For Sebastopol customers, stocking common parts locally means a damaged valve or a wrong-size shower arm doesn’t hold your project hostage for a week. We also work with homeowners who are planning larger green-building or alternative-construction projects that involve firms like Mighty Buildings; if your bathroom is part of that kind of scope, we’ll align our work with the building envelope details those systems require. The point is the same: name-brand products, written guarantees, and no off-brand substitutions.

Common Bathroom Remodeling Problems We See in Sebastopol Homes

• Fog-driven mold and wall rot: Sebastopol sits in a marine air corridor that funnels Pacific fog inland, keeping homes measurably cooler and more humid than Santa Rosa just seven miles east. Bathroom walls that were never detailed for vapor management – the old unvented walls, the tile-on-drywall jobs – hold that moisture and fail early. We fix the framing conditions before we set any tile.
• Slabs built on former orchard land: Many lots in Sebastopol were once Gravenstein apple orchards, and decades of agricultural soil amendment plus residual root systems mean the ground under your bathroom slab may not behave like typical fill. We scope the subfloor and slab condition before rough-in so a settling floor doesn’t crack your new tile in six months.
• Mid-project flood zone discoveries: We have been called in after other contractors started a bathroom on a Sebastopol parcel, only to learn the finished floor had to be raised 12 – 24 inches to meet FEMA elevation requirements. That rework means redoing steps, garage slab transitions, and stub-outs. We run the flood determination first, so that doesn’t happen on our jobs.
• Outdated rough-ins and stack placement: Older Sebastopol homes, from the Victorians to the mid-century ranchers, often have cast-iron drains and under-sized vent stacks. A remodel that doesn’t address the rough-in leaves you with a beautiful bathroom that gurgles and backs up in February rain. We re-stub and re-vent where the code and your existing framing allow it.
