Los Altos presents two distinct remodeling environments, and we’ve worked in both. Our crews handle everything from builder-grade master-planned homes off Covington Road and Magdalena Avenue where the original 6×6 white tile is still in place, to recent custom builds in the hills where a previous owner’s high-end finishes are being replaced after only a few years. The permitting, warranty, and HOA strategies differ completely between these two scenarios. We’ve delivered 4,000-plus projects since 2007, every one with a written price before work started and a documented photo record when we left.
Why Rowan Construction Group Cupertino Is Los Altos’s Preferred Bathroom Remodeling Company
Our Bathroom Remodeling team serves Los Altos from our San Francisco Bay Area dispatch office, with crews that know the local building departments and the specific conditions of this market. We’ve worked through the City of Los Altos’s Architectural and Site Review process on multiple projects, so we know the two-to-four-month design-review timeline that catches contractors accustomed to Sunnyvale’s faster commercial-oriented permitting.
Los Altos homeowners research contractors the way they research appliances, and we build for that. Our three-star reviews get read alongside the five-star ones, so we leave a documented photo record on every visit - included as standard, not an upgrade - and we deliver a written flat price with scope before anyone picks up a tool. Under Clause 1 of The Haven Standard, the price is written before anyone starts. No exceptions.
Our crews are background-checked and uniformed. A live person answers calls 24/7. And our 365-Day Done Right Promise is printed on every page, backed by a terms page you can actually read - not an asterisk.
Our Bathroom Remodeling Services in Los Altos

Full Bathroom Remodeling
A full bathroom remodel in Los Altos runs $9,000-$28,000 depending on whether we’re working in a 1950s ranch with original cast-iron drain lines or a 2016 production build with modern plumbing rough-in. In the older stock near downtown Los Altos, we regularly encounter knob-and-tube-era electrical panels that require full upgrades under permit. In newer homes off Foothill Expressway corridors, the plumbing and electrical are often fine but the waterproofing and tile installation are the weak points. We assess what’s actually failing before we quote replacement.

Walk-In Showers & Shower Remodeling
Walk-in shower installation in Los Altos costs $4,500-$12,000. This is our most requested upgrade in master-planned Los Altos homes where the original 60-inch tub and basic shower surround are still in place. We were called to a 2016-built home off Covington Road in north Los Altos where the master bath still had the builder’s original 12×12 ceramic tile and a standard 60-inch tub. The homeowners wanted a walk-in shower with a frameless glass enclosure and a new vanity, but the builder warranty was still active on the waterproofing. We pulled the shower pan and found the original fiberglass receptor had been set directly on a plywood subfloor with no mortar bed, which is common in production builds. We documented it, filed a warranty claim with the original builder, and after they signed off we installed a new Schluter shower system with a custom mud bed, a 48-inch linear drain, and a 60-inch double vanity from Wellborn. The final scope of work also included new rough-in for a hand shower and a dedicated 20-amp circuit for a heated floor.

Tub-to-Shower Conversion
Tub-to-shower conversion in Los Altos runs $3,500-$10,000. In Los Altos’s newer homes, this is rarely a simple swap. Many production builders used fiberglass receptors set on plywood without mortar beds, and the waterproofing warranty may still be active. We check the warranty status before we quote, because many Los Altos production builders allow modifications if they are permitted and inspected - but you must get written approval first or the entire wet-area warranty is cancelled. We handle that documentation as part of our process.

Vanities, Tile & Fixtures
Bathroom vanity installation in Los Altos costs $800-$3,000, with tile and fixture upgrades running higher depending on material. In Los Altos’s builder-grade homes, the vanity is often the most visible upgrade and the one homeowners tackle first. But replacing the vanity without addressing the shower pan is a common waste of money. We see this regularly in Los Altos Hills and north Los Altos - a new KraftMaid or Wellborn vanity installed over a failing shower receptor. Our written quote identifies the actual failure points so you don’t spend money on cosmetics while the waterproofing degrades.

AfterTrusted Brands We Service in Los Altos
We source across fifty-plus vetted brands, and we stock local parts for Los Altos customers to keep turnaround tight. For bathroom work, we regularly specify Kohler and Toto fixtures, Wellborn and KraftMaid vanities, and Cambria or Caesarstone for vanity tops where the customer wants stone. For shower enclosures, we work with frameless glass suppliers who understand the HOA architectural review requirements common in Los Altos’s master-planned developments. We don’t inflate quotes with brand premiums you didn’t ask for - the written price reflects the actual spec, and we document the model numbers in the scope.
Common Bathroom Remodeling Problems We See in Los Altos Homes

- Builder warranty traps. Many Los Altos homeowners assume any modification voids their builder warranty automatically. In fact, many production builders allow permitted, inspected modifications - but only with written pre-approval. Skip that step and the entire wet-area warranty is cancelled, including coverage you never touched.
- Shower pan failures hidden behind decent tile. In Los Altos’s newer master-planned homes, the 12×12 ceramic tile often looks fine while the fiberglass receptor underneath has cracked or separated from the drain. We find this with a flood test before we quote replacement, not after we’ve started demolition.
- HOA stop-work orders. Many master-planned Los Altos developments built after 2000 require architectural approval for exterior changes like new shower glass or window replacements. Ignoring this can halt your project mid-stream. We verify HOA requirements before we submit permits.
- Undersized electrical for modern loads. Los Altos’s 1950s-1970s ranch homes often have subpanels that can’t handle the 20-amp heated floor circuit or multiple GFCI outlets a modern bathroom requires. We identify this in our initial assessment and include the panel upgrade in the written scope if needed.

FAQs - Bathroom Remodeling in Los Altos

Yes, in many cases - but you must get written pre-approval from the builder for permitted, inspected work. Many production builders in Los Altos allow modifications that meet code and pass inspection, but if you proceed without written approval, the entire wet-area warranty is cancelled. We handle this documentation as part of our initial assessment. Call (669) 202-9618 and we’ll check your warranty status before we quote.
The shower waterproofing and pan, not the vanity. In Los Altos’s master-planned homes, the plumbing rough-in and electrical are often adequate, but the fiberglass receptor and tile installation are the weak points. Replacing the vanity while the shower pan fails is a common waste of money. We assess the actual failure points with a flood test and deliver a written scope that addresses what’s actually degrading. Call (669) 202-9618 for a free assessment.
If your home is in a master-planned development built after 2000, probably yes - especially for exterior changes like new shower glass or window replacements. Many Los Altos HOAs require architectural review before work starts, and ignoring this can result in a stop-work order. We verify HOA requirements before we submit permits. Call (669) 202-9618 and we’ll confirm what’s required for your specific development.
A typical Los Altos bathroom remodel takes 3-6 weeks from permit approval to final inspection, with design and permitting adding 4-8 weeks before that. Los Altos’s Architectural and Site Review process can add two to four months for substantial alterations, so we front-load that timeline in our planning. The actual construction sequence: demolition (2-3 days), rough plumbing and electrical (3-5 days), inspection, waterproofing and tile (1-2 weeks), fixtures and finish (3-5 days), final inspection. Call (669) 202-9618 for a schedule tailored to your scope.
