AfterFast, Reliable Bathroom Remodeling Across Los Altos
Bathroom remodeling in Los Altos typically runs $9,000-$28,000 for a full renovation, with most projects taking 3-6 weeks from permit to final inspection. We’re Rowan Construction Group Santa Clara, and our crews work Los Altos regularly - from the Eichler clusters along Magdalena Avenue to the ranch-style homes off Covington Road and the teardown-to-custom-rebuild lots near downtown. Dispatch and scheduling are coordinated from our San Francisco Bay Area office, but the crew that arrives at your door knows Los Altos’s design review process, its 28-foot height caps, and the expansive clay soils that can turn a simple slab pour into a geotechnical exercise. Call (669) 259-1843 to schedule your free estimate. We’ll bring a written price before any work starts, every time.
Why Rowan Construction Group Santa Clara Is Los Altos’s Preferred Bathroom Remodeling Company
We’ve delivered bathroom remodels across Los Altos since 2007 - 4,000-plus projects total, every one with a written price before a tool came out of the truck. Our Bathroom Remodeling team understands the local conditions that move a project’s scope and cost: the post-tensioned slabs in 1960s ranches, the radiant-heat tubing embedded in Eichler concrete, and the design review board that scrutinizes every exterior-facing window and roofline before a permit issues.
Los Altos homeowners research contractors the way they research appliances. They read the three-star reviews. They want the price range on the page before they make contact. We put the number in writing - flat price, written scope, written warranty - because Clause 1 of The Haven Standard demands it. Our 365-Day Done Right Promise is printed on every page, backed by a terms page, not an asterisk. Background-checked, uniformed technicians. A live person answering calls 24/7. And a documented photo record on every visit, included as standard.
Grant Rowan built this discipline. Haven acquired Rowan for it.
Our Bathroom Remodeling Services in Los Altos
Full Bathroom Remodeling
In Los Altos, full bathroom remodeling often sits at a crossroads. Because residential lots here routinely sell for $2.5-4M+ while the original 1,950-2,400 sq ft mid-century ranch represents a fraction of that land value, many homeowners initially call us for a bathroom-only scope and end up pivoting to a full teardown-and-custom-rebuild. We’re equipped for both. Our Bathroom Remodeling in Los Altos process starts with an honest assessment: if the slab, the electrical panel, and the plumbing risers all date to 1962, we’ll tell you before you spend $18,000 on a bathroom that gets demolished in eighteen months. If a standalone remodel makes sense, we scope it to Los Altos’s design review requirements and pull permits through the city’s planning department with a full material schedule attached.
Walk-In Showers & Shower Remodeling
Walk-in shower installation in Los Altos runs $4,500-$12,000, depending on whether we’re cutting into a post-tensioned slab, working around Eichler radiant tubing, or setting a curbless pan on a new pour. The Santa Clara Valley’s expansive montmorillonite clay soils - prevalent across Los Altos’s flatter residential streets - swell and shrink with seasonal moisture changes. A shallow slab cracks tile and pulls shower pans out of level within a season. We don’t pour until we know what’s underneath. That means a geotechnical report on suspect soils, deepened footings where indicated, and a post-tensioned or engineered slab before the waterproofing membrane goes down. The membrane, by the way, is the continuous sheet barrier that keeps water from migrating through grout joints into the subfloor - we specify liquid-applied or sheet membrane by Noble Company or Laticrete, and we photograph every seam before tile covers it.
Tub-to-Shower Conversion
Tub-to-shower conversion in Los Altos costs $3,500-$10,000. The price moves based on three things: whether the existing tub sits on a slab or a framed subfloor, whether the drain line needs relocation (common in 1950s ranches where the tub drain centers don’t match modern shower bases), and whether the wall behind the tub contains asbestos-containing acoustic texture - still present in pre-1978 Los Altos homes. We test before we cut. We don’t guess. And we don’t proceed with demolition until the written scope specifies the disposal pathway and the air-clearance protocol if asbestos is found.
Vanities, Tile & Fixtures
Vanity installation runs $800-$3,000 in Los Altos, but the real variable is the material selection. We source across fifty-plus vetted brands - Kohler and Toto fixtures, Cambria and Caesarstone countertops, KraftMaid and Wellborn cabinets - so the written quote carries honest numbers rather than inflated allowances. Tile work follows the same discipline. We specify membrane type, grout brand (Mapei or Laticrete), and expansion joint placement in the written scope before demolition starts. No allowance games. No “allow $1,200 for tile” that turns into $3,400 when you pick the porcelain you actually want.

AfterTrusted Brands We Service in Los Altos
We stock and install Kohler, Toto, Moen, Delta, Cambria, Caesarstone, KraftMaid, Wellborn, Laticrete, Noble Company, and Schluter products for Los Altos jobs. Our relationships with these manufacturers mean we don’t markup through a middleman - the price in your written quote reflects our direct cost plus a documented margin. For Eichler-specific work, we maintain contacts with suppliers who understand the low-flow fixtures and compact vanities that suit the smaller footprints and slab-on-grade construction of post-and-beam homes. Parts arrive on time because we order them when we scope, not when we demo.
Common Bathroom Remodeling Problems We See in Los Altos Homes
- Teardown-bound bathrooms scoped as standalone remodels. A homeowner on a $3.5M lot calls for a $15,000 bathroom update, not realizing the design review process, geotechnical report, and slab engineering required for any meaningful structural work will blow past a bathroom-only budget. We flag this in the first walkthrough.
- Expansive clay under shallow slabs. The montmorillonite clay beneath Los Altos’s flatter streets swells when wet and shrinks when dry. A bathroom remodel that ignores soil conditions - skipping the geotech report, pouring a standard 4-inch slab - produces cracked tile and out-of-level shower pans within a year. We engineer for the soil we find, not the soil we hope for.
- Eichler radiant tubing severed during rough-in. Cutting into a slab to relocate a toilet drain or add a second sink without knowing the hydronic tube layout destroys the heating system. We use thermal imaging and as-built drawings before we cut, and we staff Eichler-experienced plumbers who’ve done this dozens of times.
- Verbal walkthroughs with no written fixture allowances. A competitor bids $12,000 “plus tile and fixtures” and the first change order hits when the client selects anything above builder-grade. Our quotes specify brand, model, and allowance - or we quote the actual selection if you’ve already chosen.

What moves the price? Soil conditions requiring geotechnical work. Design review timeline (adds 4-8 weeks to permit approval). Material selection - Cambria versus builder-grade laminate, Toto Neorest versus standard Kohler. And whether the project is standalone or part of a larger rebuild, which changes the sequencing, the inspection schedule, and the draw structure. We scope all of this before we quote.

FAQs - Bathroom Remodeling in Los Altos
Usually not, unless you need functional bathrooms during a long planning phase before the rebuild. On a 12,000 sq ft lot off Covington Road, our crew pulled the original single bath in a 1960s ranch where the client briefly considered a bathroom-only remodel, then pivoted to a ground-up custom rebuild. We scoped the new bath’s rough-in only after a geotechnical report flagged expansive Santa Clara Valley montmorillonite clay, so we deepened the footings and set the post-tensioned slab before any Kohler or Moen fixture made it into the subfloor. Our schedule then ran through Los Altos design review for the 28 ft height cap and FAR, with a draw schedule keyed to inspection sign-off at each stage. If your land value exceeds your structure value by 5x or more, we’ll tell you before you spend money on a bathroom that gets demolished. Call (669) 259-1843 and we’ll walk through the math.
You need one if the work involves cutting into or pouring new concrete on a slab foundation, which most Los Altos bathroom remodels do. The expansive clay soils beneath the city’s flatter residential streets - montmorillonite clay that swells when wet and shrinks when dry - routinely require deepened footings or post-tensioned slabs to prevent cracking and level failure. We don’t pour until the report is in hand. Skipping this step is how you get a $12,000 shower that pulls out of level in eleven months. Call (669) 259-1843 and we’ll review whether your specific project needs geotechnical work during the free estimate.
Los Altos imposes its own design review process on projects before permits issue, enforcing strict height limits (typically 28 ft), floor-area-ratio caps, and neighborhood-compatibility standards - a layer of scrutiny that neighboring Mountain View and Sunnyvale do not impose in the same way. For a standalone interior bathroom remodel, design review may be streamlined if no exterior changes are proposed. But if your remodel is part of a larger addition or rebuild, expect 4-8 additional weeks for plan approval, and expect to document materials, colors, and rooflines. We navigate this process regularly and build the timeline into our project schedule. Call (669) 259-1843 for a realistic permit timeline with your quote.
An Eichler bathroom remodel requires knowledge of radiant-heat-in-slab systems, post-and-beam load paths, and the low-slope roof drainage that affects venting and exhaust. Cutting into a slab to run new plumbing or electrical without severing embedded hydronic tubing is not a standard plumbing job - it requires thermal imaging, careful layout mapping, and often a plumber who’s worked on Eichlers specifically. Adding load to post-and-beam walls that were never designed to carry it, or installing a heavy stone vanity on a slab that was engineered for distributed weight, can compromise the structure. We’ve done this work. We staff for it. And we document the as-built conditions before we cut. Call (669) 259-1843 if your home is Eichler-built - we’ll send the right crew.
We write the price before anyone picks up a tool, and no work proceeds on a change until the change order is signed. That’s the administrative discipline Haven acquired Rowan for, and it’s why our projects finish within a few percent of the agreed cost across 4,000-plus jobs. The quote specifies every material allowance by brand and model tier, every labor line item, and every contingency (typically 5-8% for concealed conditions in older Los Altos homes). If we find asbestos behind the tub surround, the contingency covers it - no emergency call, no renegotiation. If you upgrade your tile selection after signing, we write the change, you sign it, and the new price is locked before the order goes in. No verbal promises. No “we’ll figure it out later.” Call (669) 259-1843 for a quote you can screenshot and compare.
