Fast, Reliable Bathroom Remodeling Across Montclair
Bathroom remodeling in Montclair typically runs $9,000 – $28,000 for a full project, with smaller scopes like a walk-in shower installation landing between $4,500 and $12,000. The biggest variable isn’t the tile you pick. It’s what we find when we open the walls of a 1950s stucco-over-wood-frame tract home: outdated supply lines, notched load-bearing framing, or a slab crack running under the old tub from the expansive alluvial clay. Our crew works in Montclair every week, and Trevor Nash leads each project with a written price before demo day. Call (936) 259-2607 to schedule a free estimate.
Why Penhallow Remodeling Is Montclair’s Preferred Bathroom Remodeling Company
Montclair homeowners tell us the same story: a crew from Pomona across Garey Avenue gave them a verbal number, started demo, then stalled at the first San Bernardino County inspection over missing Title 24 documentation. We don’t work that way. Penhallow Remodeling runs its own building department paperwork correctly from day one, because we’ve done enough jobs in Montclair to know exactly what the city’s inspectors flag. Homeowners on Ramona Avenue, Palo Verde Street, and neighborhoods near Montclair Place know we arrive in uniform, background-checked, and with a written price already in hand.
The Bathroom Remodeling side of our company operates under the Kingswell standard: a real arrival window, a clean job site, and a 365-Day Done Right Promise in writing. If something fails inside the guarantee period, we come back and fix it at no charge. If a repair fails, the second visit is free. Those aren’t slogans. They’re the terms Trevor puts on every contract before we touch a single tile.
Bathroom Remodeling Contractor in Montclair
A Bathroom Remodeling Contractor in Montclair has to handle two things most LA County crews never think about: San Bernardino County permitting and the seismic-and-slab realities of homes built on the alluvial fan beneath the San Gabriel Mountains. When we take on a full bathroom remodel in Montclair, the job starts with an inspection, not a sledgehammer. We check the slab for cracks from the expansive clay, we look at what’s behind the drywall and under the floor, and we write allowances into the contract before demo begins. A full bathroom remodel in Montclair runs $9,000 – $28,000, and the number holds because the surprises are priced before they happen.
Permitting and Code Compliance
Montclair runs its own building department under San Bernardino County codes, and inspectors here review Title 24 energy documentation even on a single-bath scope. We pull the permit, file the paperwork, and meet the inspector on site. That’s part of the written price.
What Gets Replaced
On most 1950s-to-1970s Montclair homes, a full remodel means new supply lines, updated waterproofing behind the shower walls, and often a framing repair where an old drain run notched a load-bearing corner. We price each of these as a line item you approve in writing before we proceed.
Walk In Shower in Montclair
A Walk In Shower in Montclair costs $4,500 – $12,000, and it’s the single most common upgrade we do for homeowners who want to age in place or just get rid of a tub they never use. The conversion isn’t as simple as pulling the tub and setting a pan, especially in older tract homes where the original bath was built around a specific drain location. We start with a moisture test and a slab check, because tiling over a crack in the alluvial clay means a pan that leaks within a season. The good news: a walk-in shower opens the room, improves access, and removes the bathtub lip that trips people.
Frameless Glass and Curbless Options
We install frameless glass enclosures and curbless shower bases where the slab allows it. Curbless works best when we can recess the pan or build up the floor slightly, and we’ll tell you honestly which option your foundation can handle.
Tub-to-Shower Conversion
Converting a tub to a walk-in shower in a Montclair home runs $3,500 – $10,000. The big question is drainage: many original tubs sit on a slab that needs a new drain route. We handle that with a signed change order, not a surprise invoice.
Trusted Brands We Service in Montclair
We stock and install materials from Kohler, Moen, Delta, and Toto, along with Cambria and Silestone quartz for vanities and bench tops. We also work with more specialized sources like Cover and Dvele when a Montclair homeowner wants prefabricated bathroom components or panelized systems that speed up a gut remodel. Because we carry common local parts and have supply relationships across the Inland Empire, a fixture or valve replacement doesn’t turn into a two-week wait. The brands behind the work carry their own warranties, and they stack on top of our 365-Day Done Right Promise rather than replacing it.
Common Bathroom Remodeling Problems We See in Montclair Homes
- Slab cracks under the tub or shower. The alluvial soils on the south-facing fan swell with winter rain and shrink in summer heat. A crack that starts as a hairline becomes a leak path once the new pan goes in. We moisture-test before we tile.
- Original galvanized supply lines. Most 1950s and 1960s Montclair homes still have galvanized piping that’s corroded from the inside. We re-rough with PEX on nearly every full remodel, and it’s priced in the initial scope.
- Notched load-bearing framing. Decades ago, someone ran a drain through a corner stud to save time. It held for a while. When we open the wall for a walk-in shower or a moved vanity, that notch becomes a repair, not a mystery.
- Failed 1970s waterproofing. The green board and tar-paper era doesn’t hold up. Moisture behind the tile rots the framing and feeds mold. We strip to the studs, replace the damaged wood, and install cement board substrate (the moisture-resistant layer behind your tile) before anything else goes up.

FAQs About Bathroom Remodeling in Montclair
Because Montclair runs its own San Bernardino County building department, and the inspectors here enforce Title 24 energy documentation and seismic review that LA County crews from Pomona don’t normally prepare. A permit that goes smoothly in Pomona can stall in Montclair over missing paperwork, and that delay costs money. Add the alluvial-fan slab and the older framing, and the opening work is simply more involved. Call (936) 259-2607 for a written price that accounts for all of it.
A full bathroom remodel in Montclair runs $9,000 – $28,000. The price moves on four things: what’s behind the walls, whether the slab has cracked, whether you’re moving plumbing, and the cabinet and countertop material you select. We write the allowances into the contract before demo so the number doesn’t drift. Call (936) 259-2607 for a free estimate.
Yes, in nearly every case. Montclair requires permits for plumbing changes, electrical work, and any structural modification, including moving a wall for a walk-in shower. We pull the permit, file the Title 24 documentation, and meet the inspector on site as part of the written price.
We plan for it before the walls come down. Trevor writes allowances into the contract for the likely discoveries on a Montclair home: galvanized supply lines, notched framing, slab cracks, failed waterproofing. If we find something outside the allowance, we stop, show you the situation, and get your signature on a written change order before we proceed. Nothing is a mystery line item. Call (936) 259-2607 to talk through your project.
Yes, and we do it often. The conversion runs $3,500 – $10,000, depending on the drain location and what the slab looks like under the old tub. On a 1958 stucco-over-wood-frame home off Garey Avenue, our crew opened a hall bath and found the original galvanized supply lines, a load-bearing corner notched for an old drain, and a slab crack running straight under the tub. We wrote the allowance before demo, priced the framing repair and PEX re-rough as a signed change order, and the homeowner’s total stayed inside the Bathroom Remodel range because nothing was unplanned. Call (936) 259-2607 to schedule your free estimate.
