We serve Los Altos from our San Francisco Bay Area office, with crews dispatched directly to neighborhoods from Loyola Corners to North Los Altos to the Country Club area. Grant Rowan built this company on a simple standard: every customer gets a written price before any work starts, and no change proceeds without a signed change order. In Los Altos, where land values have pushed construction toward teardown-rebuilds and high-spec gut renovations, that discipline matters more than ever. The original 100-amp panels and post-and-pier framing in 1950s-70s ranches here create surprises behind bathroom walls that cosmetic-only quotes simply don’t account for. We do.
Why Rowan Construction Group Palo Alto Is Los Altos’s Preferred Bathroom Remodeling Company
We’ve delivered over 4,000 projects since 2007, every one with a written price before work started and a documented photo record when the crew left. In Los Altos, that history includes gut renovations of mid-century ranches where the real work turned out to be electrical rough-in and subfloor repair, not tile selection.
Our crews are background-checked and uniformed; a live person answers calls 24/7. The 365-Day Done Right Promise is printed on every page, backed by The Haven Standard terms page, not an asterisk. Under Clause 1, the price is written before anyone starts.
We offer a Free Second Opinion on any written estimate. Bring a competitor’s quote and we’ll review it line by line at no charge. In a market where Los Altos lots routinely exceed $2-3M and contractors are rarely patching but replacing entire structures, that transparency is how we’ve kept projects within a few percent of the agreed cost.
Our Bathroom Remodeling Services in Los Altos
Full Bathroom Remodeling
A full bathroom remodel in Los Altos almost always means working inside a 1950s-70s California ranch with post-and-pier foundations and original 100-amp electrical panels. Because nearly every Los Altos bathroom remodel now happens inside a teardown-rebuild or high-spec gut renovation, the permit-triggered upgrades, not the tile, are what move the number. Neighboring Sunnyvale and Mountain View still have enough untouched mid-century stock that a straight cosmetic bath refresh is a realistic option there in a way it rarely is in Los Altos. Our Bathroom Remodeling team inspects the substrate, the electrical feed, and the framing before we quote, then writes allowances into the contract for what we expect to find.
Walk-In Showers & Shower Remodeling
Walk-in shower installation in Los Altos runs $4,500-$12,000. The demand here is driven by aging-in-place renovations and tech-industry buyers who expect curbless entries, linear drains, and frameless glass. But the real variable is what’s under the old shower: failed pan waterproofing is common in 60-year-old ranches, and the subfloor repair adds scope that a simple fixture swap never touches. We price the pan, the membrane, and the valve rough-in separately so you see where the money goes.
Tub-to-Shower Conversion
Tub-to-shower conversion in Los Altos costs $3,500-$10,000. On a 1962 single-story ranch off Foothill Expressway, our crew opened a guest bath for this exact conversion and found the original 100-amp panel feeding a circuit that wouldn’t carry a modern GFCI layout, plus a subfloor softened by decades of failed pan waterproofing. We pulled a Los Altos building department permit, wrote the electrical rough-in and subfloor repair as allowances in the scope of work, priced each discovery as a signed change order before demo continued, and scheduled the framing phase around the late-season rain window. The punch list closed clean after the city’s inspection sign-off on the new pan and valve rough-in.
Vanities, Tile & Fixtures
Vanity installation runs $800-$3,000 depending on whether we’re moving plumbing or dropping into existing locations. In Los Altos, we source from fifty-plus vetted brands including Kohler and Toto fixtures, with Cambria and Caesarstone available for integrated vanity tops. The tile work gets specified by membrane type, not just aesthetics: liquid-applied vs. sheet membrane, flood-tested before cover. We document each layer with photos you receive as standard, not as an upgrade.

Common Bathroom Remodeling Problems We See in Los Altos Homes
- Original 100-amp electrical panels and two-wire branch circuits force a panel and rough-in upgrade the moment the permit makes the walls visible. This is a line item absent from cosmetic-only quotes, and it’s why we inspect the electrical feed before we price.
- Post-and-pier foundations and variable expansive clay near Foothill Expressway mean a bath remodel on an unretrofitted ranch can surface load-bearing and subfloor fixes that a flat-valley city would never trigger. We write these as contract allowances, not surprises.
- Failed pan waterproofing in 60-year-old showers is nearly universal in the original housing stock. The damage is often hidden until demo, which is why we price the pan replacement as a separate line item with a written change order threshold.
- Late-season El Niño rain catching an open, unroofed bathroom during framing and rough-in, after a contractor scheduled to the long dry season and left the structure exposed. We build weather contingencies into the schedule, especially for projects near the foothill transition where rain patterns are less predictable.

FAQs - Bathroom Remodeling in Los Altos
Los Altos land values have pushed construction toward teardown-rebuilds and high-spec gut renovations, so a “remodel” here routinely means opening walls with original 100-amp panels and post-and-pier framing that trigger permit-required electrical and structural upgrades. Sunnyvale and Mountain View still have enough untouched mid-century stock that a straight cosmetic bath refresh is realistic there in a way it rarely is in Los Altos. Those upgrades are line items we write into our quotes as allowances, not surprises. Call (650) 446-9092 for an exact quote - estimates are free.
Yes, if you have heritage oaks or protected trees within the construction envelope. Los Altos enforces its own Protected Tree Ordinance, requiring certified arborist reports and protective fencing plans before grading or demo permits are issued. This routinely adds 6-10 weeks to project timelines and catches out-of-area contractors off guard. We factor this into our scheduling and permit coordination. Call (650) 446-9092 to discuss your lot specifically - estimates are free.
We inspect before we quote, write allowances into the contract for what we expect to find, and price any discovery as a signed change order before work continues. On that 1962 ranch off Foothill Expressway, we found a 100-amp panel that wouldn’t carry modern GFCI circuits and a subfloor softened by failed waterproofing. Each item was written, priced, and signed before demo resumed. No work proceeds on a change until the change order is signed - that’s the Haven Standard discipline that has kept our projects within a few percent of the agreed price since 2007. Call (650) 446-9092 for an exact quote - estimates are free.
Yes. Los Altos sits at the transitional edge between the Santa Clara Valley floor and the foothills, and late-season El Niño rain events can catch excavation and framing phases exposed. We schedule the weather-sensitive portions of Los Altos projects around the long Mediterranean dry season, but we also build contingency into the timeline for the foothill transition zone where rain patterns are less predictable than flat valley cities. Call (650) 446-9092 to discuss scheduling for your specific project - estimates are free.
Yes, for any work involving plumbing, electrical, or structural changes - which is nearly every bathroom remodel in Los Altos given the age of the housing stock. Los Altos has its own municipal building department, not Santa Clara County, and they inspect rough plumbing, electrical, and framing before cover. The permit is what triggers the discovery of code upgrades like panel replacements and GFCI circuit requirements. We pull permits as standard, coordinate inspections, and pass them before we close walls. Call (650) 446-9092 to schedule your free estimate.
