Call (510) 686-6370

We know Martinez well. From the pre-1940 balloon-frame homes in the downtown flatlands to the mid-century ranches on the upper slopes near Alhambra Valley, we’ve scoped and priced bathrooms in this market long enough to know that a remodel here rarely follows the standard playbook. The city’s position on the Carquinez Strait, its expansive Altamont clay soils, and its status as one of the oldest incorporated cities in the East Bay (1876) all introduce variables that newer contractors miss. Call (510) 686-6370 to schedule your free estimate. Our Bathroom Remodeling team will walk your property, document conditions with photos, and deliver a written price before any work starts.

Why Rowan Construction Group Walnut Creek Is Martinez’s Preferred Bathroom Remodeling Company

We’ve completed bathroom remodels across Martinez’s distinct neighborhoods, from the historic downtown core near the county courthouse to the hillside properties off Alhambra Valley Road. Our crews understand the local failure patterns: clay-soil heave undermining subfloors, delta-wind moisture intrusion through aging balloon-frame walls, and the permitting nuances of working in the Contra Costa County seat.

Our reputation here is built on documentation, not promises. Every Martinez project receives a written flat price with scope before work begins, a signed change order for any modification, and a documented photo record of every visit. Under the 365-Day Done Right Promise, if something isn’t done right, we make it right - backed by The Haven Standard, not a handshake. Homeowners in Martinez also receive our Free Second Opinion on any written estimate: bring a competitor’s quote and we’ll review it line by line at no charge.

Calls are answered by a live person 24/7, and our technicians are background-checked and uniformed. We’ve kept projects within a few percent of the agreed price across 4,000-plus jobs since 2007 by enforcing one rule: no work proceeds on a change until the change order is signed. That’s the discipline Haven acquired Rowan for, and it’s how we operate in Martinez.

Our Bathroom Remodeling Services in Martinez

Tub-to-Shower Conversion

Tub-to-shower conversion in Martinez runs $3,500-$10,000, but the number changes fast if clay-soil movement has cracked the slab or shifted the subfloor beneath the tub. On hillside lots, we evaluate the foundation before quoting fixture work. In the Alhambra Valley area, we’ve found that seasonal heave often undermines the original installation, turning what looks like a simple swap into a structural repair. When the substrate is sound, we install Kohler or Toto fixtures with waterproofing membranes and frameless glass enclosures. Every conversion includes slope verification and drainage testing before sign-off.

Walk-In Shower Installation

A walk-in shower installation in Martinez typically costs $4,500-$12,000. The delta winds that funnel through the Carquinez Strait deliver more persistent marine moisture than contractors encounter a few miles inland in Walnut Creek or Pleasant Hill, so we specify vapor barriers and waterproofing membranes more aggressively here. In older homes near downtown Martinez, we often discover balloon-frame wall cavities that have trapped moisture for decades. Our crews document the framing condition with photos, explain what we found in plain terms, and write the repair scope into the quote before tile goes up.

Small Bathroom Remodels

Small bathroom remodels in Martinez start at $5,000 and range to $12,000. These projects punch above their weight in pre-1940 homes because the compact footprint often conceals outdated electrical, galvanized plumbing, and unpermitted prior work. We inspect for these conditions during the initial walk-through and flag them in the written quote. For homeowners near the county courthouse or in the lower hillside neighborhoods, we’ve learned to budget time for Contra Costa County permit review, which can add a week to scheduling but protects the resale value of historic-sensitive properties.

Full Bathroom Remodeling

A full bathroom remodel in Martinez runs $9,000-$28,000 and encompasses everything from demolition to final fixture installation. These projects often start with foundation and subfloor evaluation, not tile selection, because Altamont clay soils heave and swell dramatically between dry summers and wet winters. On a hillside property in the Alhambra Valley area, our crew tore out a failing tub-to-shower conversion and found the original subfloor had been undermined by clay-soil heave and old moisture intrusion. We treated the repair as a structural scope, then rebuilt the rough-in, brought in Kohler fixtures, and added a frameless glass shower enclosure after inspection sign-off. The final walk-through included a punch list that confirmed drainage and slope corrections around the open lot before we closed out the job.

Trusted Brands We Service in Martinez

We source across fifty-plus vetted brands, giving Martinez homeowners honest numbers rather than inflated allowances. For bathroom remodels, we regularly specify KraftMaid and Wellborn cabinets, Cambria countertops, and Kohler and Toto fixtures. We don’t ask customers to select from a showroom and hope the allowance covers it. We price the actual SKU, deliver the written quote, and order once the scope is signed. This eliminates the change-order surprises that plague Martinez remodels, especially on hillside lots where material hauls and equipment access already complicate logistics.

Common Bathroom Remodeling Problems We See in Martinez Homes

• Clay-soil movement cracking slab and tile. The Altamont clay underlying Martinez’s hillsides shrinks and swells seasonally, cracking flatwork and shifting subfloors. A simple vanity replacement can become a structural repair once the subfloor is exposed. We inspect for this on every hillside project and write the finding into the quote.
• Delta Strait wind-driven moisture rotting balloon-frame walls. Marine moisture funnels inland through the Carquinez Strait and works through the old building envelope faster than in drier inland cities. We regularly find rotted framing behind shower walls and mold behind tile in pre-1940 homes near downtown Martinez.
• Unpermitted prior work triggering county holds. Because so much of Martinez’s housing stock predates modern codes, we frequently discover unpermitted plumbing and electrical during rough-in. This forces a county inspection sign-off hold and a change order to bring systems up to code. We flag this possibility upfront in our written quotes.
• Lead and asbestos abatement in historic properties. As one of the oldest cities in the East Bay with many late-Victorian and Craftsman structures, Martinez remodels routinely require abatement work rarely seen in newer neighboring cities. We coordinate certified abatement contractors and include their scope in our project sequencing.
