Fast, Reliable Bathroom Remodeling Across Martinez
A full bathroom remodel in Martinez typically runs $9,000 to $28,000, and most projects take three to six weeks depending on whether the hillside ordinance review is triggered. If you live off Alhambra Valley Road, on a sloped lot near Hidden Lakes, or in a pre-1960 Craftsman near downtown, the single most important decision you’ll make is hiring a contractor who already knows how Martinez’s hillside and drainage rules shape the job. Call (831) 480-4497 and you’ll get Graham Stein or another live person, not a voicemail box.
Why Elmstead Remodeling San Francisco Is Martinez’s Preferred Bathroom Remodeling Company

Families in Martinez call us because we show up with a written price before any work starts, and we put it in your hand before the first tool comes off the truck. That’s the Cedarwell Care Promise, and it applies to every project we take on in Martinez, from small hall baths near downtown to primary suites in the hills.
Our crews drive into Martinez from the San Francisco Bay Area dispatch office, and we schedule around your house, not ours. Quiet tools during nap hours, shoe covers at the door, drop cloths on every floor path, and a photo of the clean-up before we leave. These are not add-ons. They’re the way we work.
Graham Stein leads every Martinez project personally. When you call to ask about a hillside permit question or a tub-to-shower conversion, you’re talking to someone who has walked those Alhambra Valley lots and knows what the geological review will ask for.
Styles & brands we work with







Bathroom Remodeling Contractor in Martinez
A Bathroom Remodeling Contractor in Martinez does more than swap finishes. The job starts with checking whether your home sits on a slope that triggers the city’s hillside ordinance, and whether the original framing on a pre-1960 raised foundation can carry the weight of modern tile and a cast-iron tub. A full remodel on a flat lot near Hidden Lakes may move quickly. The same job on a hillside off Alhambra Valley Road can add weeks for geological review and slope-disturbance permits.
Full Bathroom Remodeling
We gut the space to studs, correct framing and subfloor issues, reroute plumbing where the layout calls for it, and rebuild with products you can research by name. KraftMaid or Wellborn vanities, Cambria or Silestone countertops, Kohler or Moen fixtures. The work ends with a documented permit sign-off and our 365-Day Done Right Promise.
Small Bathroom Remodels
Martinez has a lot of compact baths in 1940s and 1950s homes. We handle layout changes that make a 5×8 bath feel usable, and we do it without triggering unnecessary permit scope. A small bath remodel here typically runs $5,000 to $12,000, and we still give you the written price before work begins.
Walk In Shower in Martinez

A Walk In Shower in Martinez costs $4,500 to $12,000 installed, and the price depends on glass enclosure style, tile choice, and whether the existing drain and pan need to be rebuilt after years of clay-soil movement. Many Martinez homes we see have original shower pans cracked from foundation settling, and a walk-in conversion is often the cleanest fix.
Frameless Glass Shower Enclosures
Frameless glass opens up a small Martinez bath more than almost any other change. We template after tile is set, so the glass fits the actual finished walls, not the plan. In hillside homes where floors are never perfectly level, that matters.
Tub-to-Shower Conversion
Replacing a bathtub with a walk-in shower in Martinez runs $3,500 to $10,000. On pre-1960 raised foundations, we inspect the subfloor before demolition, because sagging original framing under a tub often hides water damage that only shows up once the cast iron comes out.
Trusted Brands We Service in Martinez
We install and service cabinets from KraftMaid and Wellborn, countertops from Cambria and Silestone, and fixtures from Kohler and Moen. Because we stock common replacement parts locally for Martinez customers, a damaged vanity drawer or a leaking valve during the warranty period gets handled faster. Manufacturer warranties stay with the finished project, and our 365-Day Done Right Promise covers the workmanship on top of that.

AfterCommon Bathroom Remodeling Problems We See in Martinez Homes
- Hillside ordinance triggers. Moving a drain line or touching an exterior wall on a sloped lot can require geological review and slope-disturbance permits before rough-in. Skipping this step halts the permit and forces a costly soils report mid-project.
- Subfloor sag on pre-1960 raised foundations. Original framing under Martinez Craftsman and Spanish Revival homes often deflects under modern tile loads, causing cracked grout and leaking shower pans within a few years.
- Expansive clay soil movement. Martinez’s hot, dry summers and cool, wet winters make clay soils shrink and swell. We see cracked mortar beds and shifted drain lines in hillside bathrooms where drainage wasn’t accounted for.
- Undocumented compliance. Homeowners who can’t produce permit sign-offs and product ratings after a remodel face trouble when an insurer raises premiums or denies a water-damage claim. We document every inspection and material spec.

FAQs About Bathroom Remodeling in Martinez
In most cases, no. The hillside ordinance and geological review are triggered when exterior walls, foundations, or slope-disturbing work is involved. A straight shower and vanity replacement that stays within existing walls and doesn’t move drainage lines usually proceeds under a standard plumbing and finish permit. But if your drain is cracked from clay-soil movement and the plumber needs to reposition it, that can pull the job into hillside review. Call (831) 480-4497 and we’ll tell you which category your specific house falls into before you spend a dollar.
Wind-load requirements in Martinez apply to exterior structural changes, not interior shower glass. However, if your walk-in shower project touches an exterior wall, especially on a hillside home off Alhambra Valley Road, the city may require shear-panel or framing upgrades to meet current wind and seismic standards. That’s a code requirement many cheap quotes leave out. Our written price includes those upgrades when they apply, and the permit sign-off documents them.
Because Martinez’s expansive clay soils shrink and swell with seasonal moisture, and hillside lots shed water in ways that can move foundations and crack shower pans. A drainage plan shows where water goes after it leaves the shower drain and how the remodel won’t worsen slope or soil conditions. On several Martinez hillside jobs, the drainage plan is what the building department reviews most closely. We build it into the written quote so there are no change orders later.
It can. When you can produce final inspection sign-offs, product ratings, and drainage or shear-panel documentation, your insurer has evidence the work was done to current code. That matters in Martinez, where water-damage claims from failed shower pans or leaking drains are common, and insurers are quicker to pay when the compliance trail is complete. We give you a documentation packet with every finished project.
You need a subfloor inspection before the tub comes out. Original framing in many Martinez homes built before 1960 deflects under modern tile and glass loads, and that movement causes cracked grout and leaking pans. If the framing is undersized, we reinforce it before we set the shower base. The permit will also require the new shower pan and drain to meet current code, which often means a new P-trap and a pan liner test before the tile goes down. Call (831) 480-4497 for a free estimate, and we’ll walk the job with you.
