Fast, Reliable Bathroom Remodeling Across Martinez
If you own an older home in Martinez, you already know the drill: the bathroom looks fine at first glance, but behind the walls sits decades of patched pipes, sagging floors, and tile that’s held on with hope. Full bathroom remodeling in Martinez typically runs $9,000 to $28,000, with smaller refreshes coming in lower and complete tear-outs on the high end. We’re Barrett & Sons Construction, and we’ve spent 29 years working on exactly the homes that fill this town, from the Victorians near downtown to the post-war ranches on the eastern slopes. Call Tom and his sons at (877) 610-1318 for a free estimate, and we’ll give you a written scope before anything gets demolished.
Why Barrett & Sons Construction Is Martinez’s Preferred Bathroom Remodeling Company
Tom Barrett put his name on this company in 1998, and his sons run the crews. That’s not a marketing line. When we work on a bathroom in Martinez, the people swinging hammers and setting tile are the same people you’ll run into at the farmers market on Court Street or the hardware store on Alhambra Avenue. The guy who shakes your hand at the estimate is the same guy who owns the problem if something’s not right. That’s why the 90-Day Done Right Promise is written on every contract: if a drawer sticks or a grout line cracks after we leave, one call brings Tom back. No call center, no out-of-state dispatcher. A live person answers the phone 24/7.
We also know what Martinez homes actually hide. The older housing stock near the historic downtown district, built long before seismic codes existed, often has plumbing that’s original to the house, subfloors that have settled over adobe clay, and framing that’s drifted enough to make a simple vanity swap a real leveling job. We plan for that. Our customers in the 94553 zip code tell us the difference shows up in the written change orders before any surprise hits, and in the permit inspector signing off at the end. Look up Tom’s license number yourself. He publishes it.

Our Bathroom Remodeling Services in Martinez
Every bathroom remodel starts with a conversation about how you actually use the space. Not a sales pitch. A walk-through. Here’s what we handle for Martinez homeowners.
Full Bathroom Remodeling
A complete gut and rebuild changes the footprint, the plumbing, the electrical, and the finishes. In Martinez, that often means sistering floor joists before any tile goes down, replacing galvanized supply lines that have been corroding since the Eisenhower administration, and bringing the room up to current code. We pull permits on every eligible job in Martinez, because the inspector works for you, not for us. Full remodels in Martinez run $9,000 to $28,000 depending on square footage and how much structural correction the old framing needs.

Walk-In Showers & Shower Remodeling
A walk-in shower with a curbless entry changes how you age in place. Many Martinez homeowners in the hillside neighborhoods around Hidden Lakes Park want to stay in their homes for another twenty years, and a zero-threshold shower is often the first step. We handle pan construction, waterproofing, tile, and glass enclosures. Walk-in shower installation in Martinez typically runs $4,500 to $12,000 depending on tile choices and whether we’re moving drains.

Tub-to-Shower Conversion
Converting a bathtub to a shower opens up a small bathroom and removes a tripping hazard. In Martinez’s older Craftsman bungalows, the original tubs are often cast iron and set into floors that have settled unevenly, so we level and reinforce the subfloor before framing the new shower. Tub-to-shower conversions in Martinez run $3,500 to $10,000. The written change order covers any framing surprises we uncover once the old tub comes out.

Vanities, Tile & Fixtures
Sometimes the bones are fine and the room just needs new life. We install vanities, floor and wall tile, faucets, shower trim, and lighting. We’re not married to any single vendor, so if you want a specific vanity or a certain tile from a Martinez supplier, we’ll install it. Vanity installation alone runs $800 to $3,000 in Martinez. Tile work is priced by square footage in the written scope, not guessed at after the fact.
While you’re thinking about the outside of the house too, we also handle Roofing in Martinez, and if the bathroom window is the thing that’s failed, our Windows & Doors in Martinez team can replace it while we’re there.

Trusted Brands We Service in Martinez
We install materials you can look up, not mystery brands off a van. For shower enclosures and glass work, we lean on frameless systems from suppliers like Simonton and PGT when the job calls for impact-rated or coastal-grade glass, which matters more along the Carquinez Strait than people expect. If your Martinez home sits on a hillside that catches the wind off the water, that’s a real consideration for window openings in a shower wall or a bathroom exterior wall. We also stock common replacement parts and trim locally so a vanity swap or a fixture change doesn’t stall waiting on freight.
Common Bathroom Remodeling Problems We See in Martinez Homes
- Unbolted foundations and settled floors: Homes built before seismic retrofit requirements, especially in the older blocks near downtown Martinez, often sit on mudsills that were never bolted. The expansive adobe clay under them moves with the seasons, and by the time you notice a sloped bathroom floor, the joists have been shifting for decades. We relevel and sister joists before tile ever goes down.
- Original galvanized plumbing: The early-1900s wood-frame homes in Martinez frequently still have galvanized supply lines that are corroded from the inside. A vanity swap becomes a re-pipe job once we open the wall. We put that in the written scope as soon as we see it, not at the final invoice.
- Moisture trapped behind old tile: Homes near the Carquinez Strait get more marine air movement than Concord or Walnut Creek, and the temperature swings create condensation cycles inside exterior bathroom walls. We strip back to framing, check for rot, and install proper waterproofing systems before new tile goes up.
- Knob-and-tube remnants in bathroom circuits: Older Martinez homes sometimes still have fragments of knob-and-tube wiring feeding a bathroom fixture or outlet. A remodel is the right time to replace it with modern wiring and GFCI-protected circuits, which we do as part of the permit scope, because an insurance company may not cover a new bathroom tied to 1920s wiring.
Pricing for Bathroom Remodeling in Martinez, CA
Here’s what we quote in Martinez, in plain numbers. A small bathroom remodel, maybe a guest bath in a post-war ranch, runs $5,000 to $12,000. A full master bath with a walk-in shower, custom vanity, and heated floor starts around $9,000 and climbs to $28,000 if we’re moving plumbing, repairing framing, or upgrading an old electrical circuit. Walk-in shower installation alone: $4,500 to $12,000. Bathtub replacement: roughly $3,500 to $10,000 depending on whether we’re pulling cast iron. Vanity installation: $800 to $3,000.
What moves the number is what’s behind the walls, not the tile you pick. A Martinez home built in 1912 usually needs more structural work than one built in 1972. That’s why every estimate includes a written line-item scope, and every surprise we find becomes a written change order before we touch it. You’ll never get a bill that doesn’t match what you signed. Call (877) 610-1318 for a free estimate.

FAQs - Bathroom Remodeling in Martinez
A bathroom remodel in Martinez typically costs $9,000 to $28,000, with small bathrooms starting around $5,000 and full master suites reaching the top of the range when structural work or plumbing relocation is required. The age of your home matters here more than the finish level, because pre-1920 stock often needs joist repair and re-piping before finishes go in. Call (877) 610-1318 for an exact written quote. Estimates are free.
Yes, and those are the jobs we know best. Homes in the historic district and hillside neighborhoods of Martinez often need foundation bolts, floor releveling, and plumbing replacement before tile work begins. We factor that into the written scope up front, so you’re not surprised when the wall opens. The permit inspector signs off on every eligible job.
Yes, we pull permits and schedule inspections on every eligible bathroom remodel in Martinez. The inspector works for you, not for us, and we’d rather have the sign-off than a cheap, unpermitted job that bites you when you sell the house. If a contractor tells you permits are optional here, get a second opinion. We offer a free second opinion on any written estimate.
A standard full bathroom remodel in Martinez runs three to six weeks from demolition to final inspection, depending on what we find when we open the walls. Older homes with settled framing or old plumbing add time, because we fix those problems instead of tiling over them. You’ll get a schedule in writing before we start, and we stick to it as closely as the house allows.
Every bathroom remodel in Martinez comes with our 90-Day Done Right Promise, written on the contract. If something’s not right, one call brings Tom back to make it right. No fine print, no phone tree. After 29 years, we’ve learned that a warranty is only worth what the owner is willing to back up with his own time.
If you’re ready to talk about your bathroom, call Tom and his sons at (877) 610-1318. We’ll walk the space, give you a written scope, and let you decide. That’s the whole pitch.
