AfterFast, Reliable Bathroom Remodeling Across Martinez
Bathroom remodeling in Martinez typically runs $9,000 – $28,000 for a full gut and rebuild, with smaller refreshes starting around $5,000. Most of our Martinez jobs take two to four weeks once we open the walls, and every project gets a written price before we pull a single tile. Call (936) 259-2607 to schedule a free estimate with Trevor Nash, our lead on Martinez bathrooms. We serve the whole city, from the historic flatlands near downtown up into the hillside tract neighborhoods.
What makes Martinez different from Concord or Lafayette is the age of the homes and the ground they sit on. We’ve remodeled bathrooms in Victorians on Estudillo Street, Craftsman bungalows near the Amtrak station, and postwar ranchers up toward Morello Heights. The challenges change block by block, and we price accordingly.
Why Penhallow Remodeling Is Martinez’s Preferred Bathroom Remodeling Company
We’re not the cheapest bid in Martinez and we won’t pretend to be. What we offer is a written number that holds, a defined arrival window, and a 365-Day Done Right Promise in writing on every single bathroom project. If something fails inside that year, we come back and fix it at no charge.
Our structure is simple. Every Penhallow technician is background-checked and arrives in uniform, so the person at your door in the morning is the same person who walks through your plan at the start. A live person answers our phone 24/7, including weekends, when most Martinez homeowners finally have time to talk through their remodel. We operate under the Kingswell Guarantee, established in 2004, which means a written price before work starts, a clean job site during the project, and a written guarantee when we finish.
Trevor Nash personally reviews every Martinez bathroom scope before we send a proposal. He’s the one you’ll sit across from at the estimate, and he’s the one who signs off on the punch list.
Walk In Shower in Martinez
A Walk In Shower in Martinez homes from the flatlands era often means working around a tub alcove built before modern waterproofing existed. The job typically involves removing the old tub, checking the framing behind it for rot or missing headers, and rebuilding the alcove as a curbless or low-profile shower with a cement board substrate (the moisture-resistant layer behind your tile) and a bonded waterproof membrane. Depending on the home’s condition and finishes, a walk-in shower installation in Martinez runs $4,500 – $12,000.
Framing and Waterproofing First
Older Martinez bathrooms hide things a newer Concord tract home never would. We inspect the studs, the subfloor, and the drain line before a single tile goes up. If the wall is balloon-framed or the slab is moving with the clay, we address it before waterproofing, because a shower pan set on a heaving slab will crack within a season.
Glass, Tile, and the Salt-Air Factor
We install frameless glass enclosures with stainless hardware rated for coastal exposure. The Carquinez Strait wind carries enough salt air that standard fasteners corrode faster than you’d expect this far from the ocean. We specify materials that hold up.
Bathroom Remodeling Companies in Martinez
Bathroom Remodeling Companies in Martinez range from one-man operations running on verbal estimates to established general contractors who pull permits and stand behind their work. We fall firmly in the second camp. A full bathroom remodel in Martinez runs $9,000 – $28,000, and the spread comes down to what’s behind your walls, not how nice the tile looks on the showroom floor.
What We Do That Others Don’t
We write the price down before we start, and we write the guarantee down too. If the waterproofing fails inside a year, the fix is free. If a surprise comes up mid-job, you approve a written change order before we spend a dollar on it.
Permits and Preservation
Martinez’s historic downtown core triggers a preservation review that many contractors would rather avoid. We don’t avoid it. We handle the paperwork, pull the permit, and schedule the inspections so you never have to chase the city yourself.
Trusted Brands We Service in Martinez
We install and service materials from KraftMaid and Wellborn cabinetry, Cambria and Silestone countertops, Kohler and Moen fixtures, and more. Using recognized trade brands means the warranty behind the product stacks with our own 365-Day Done Right Promise. For Martinez homeowners considering an ADU or whole-home addition alongside a bathroom project, we’re also familiar with the prefab options from Cover and Abodu, which can sometimes shorten a timeline when the scope grows beyond a single bathroom. We keep a local materials pipeline into Martinez, so if something arrives damaged or a part fails mid-project, we’re not waiting on a shipment from across the country to keep your job moving.
Common Bathroom Remodeling Problems We See in Martinez Homes
- Shower pans cracked by moving clay. Lower Martinez sits on expansive adobe soils that swell with winter rain and shrink in summer. A shower pan set on a slab that’s still moving will fail within a season, and no amount of grout sealer fixes that. We address the structural movement before waterproofing goes in.
- Balloon-frame walls with missing headers. Homes built before WWII in the flatlands often have studs running full height with no header over the tub alcove. Opening the wall for a rough-in means the inspector will flag it, and sagging floors follow. We treat these walls as load-bearing and add proper support before the drywall goes back.
- Failed waterproofing from the last remodel. A remodel done ten years ago over a heaving slab fails in predictable ways: grout cracks, silicone pulls away, and water gets behind the tile. By the time you see the damage, the subfloor is usually shot. We strip it to the studs and rebuild correctly.
- Corroded fasteners and subfloor connections. Salt air from the Carquinez Strait attacks exposed steel and fastener connections in wet areas. We find bathroom subfloors held together with rusted screws that snap when we lift them. We replace with corrosion-rated hardware.

What moves a Martinez bathroom from the low end to the high end is usually what’s behind the walls: a moving slab that needs pier work, balloon framing with no header, or a drain line separated by decades of clay movement. We uncover those conditions during the inspection and write allowances into the contract so the number you get up front is the number you can plan around.

FAQs About Bathroom Remodeling in Martinez
Because Martinez’s older homes hide conditions that a visual estimate can’t see: undersized balloon-frame studs, missing headers, heaving slabs, and corroded drain lines. When we open the wall, the scope changes. That’s why we inspect first and write allowances into the contract, so you’re not blindsided. Any change is priced and approved in writing before we touch it. Call (936) 259-2607 to get an honest written estimate.
Yes, any scope that moves plumbing, electrical, or structural framing requires a permit from the City of Martinez. What it triggers depends on the house: in the historic flatlands, expect seismic and preservation review. We pull the permit, schedule the inspections, and pass the sign-off. You won’t be the one sitting on hold with the building department.
The expansive clay under lower Martinez swells with winter rain and shrinks in summer, and that movement heaves slabs, cracks stem walls, and separates drain connections. If we set tile over a moving slab without addressing it, the shower pan fails within a season. We check for movement during the inspection and engineer accordingly. For an exact quote, call (936) 259-2607.
Yes. We’ve remodeled bathrooms in Victorians and Craftsman bungalows near the historic downtown, working through Contra Costa’s preservation review and seismic retrofit requirements. The permit process takes longer, but it’s part of doing the job legally in an older home. We manage the paperwork and the inspections, and we don’t cut corners to speed it up.
A walk-in shower installation in Martinez runs $4,500 – $12,000, depending on the condition of the framing, the slab, and the finishes you choose. A tile shower over a stable subfloor with standard glass comes in around $4,500 – $6,500. A curbless design with structural repairs and premium hardware lands closer to $10,000 – $12,000. Call (936) 259-2607 for a written line-item quote.
