A full bathroom remodel in Sunnyvale typically runs $9,000-$28,000, with most projects fixed in writing before a single fixture is ordered.

Dispatch and scheduling run from our San Francisco Bay Area office, and we carry the same documented process to every Sunnyvale job: written price, written scope, signed change order if anything shifts. Call (669) 259-1843 to schedule your free estimate.
Why Rowan Construction Group Santa Clara Is Sunnyvale’s Preferred Bathroom Remodeling Company
We’ve delivered more than 4,000 projects since 2007, every one with a written price before work started and a documented photo record when the crew left. In Sunnyvale, that discipline matters more than most places.
The city’s post-WWII ranch stock - wood-frame, slab-on-grade, often with original 1960s plumbing - rewards contractors who inspect before they quote. We don’t estimate from photos. Our techs walk the job, check the slab condition, and flag what’s behind the tile before the number goes on paper. That upfront rigor is why our projects finish within a few percent of the agreed price.
Our 365-Day Done Right Promise applies here exactly as it does everywhere else: if it is not done right, we make it right, backed by The Haven Standard’s printed terms, not a handshake. And our Free Second Opinion on any written estimate means you can bring a competitor’s Sunnyvale quote and we’ll review it line by line at no charge.
Calls are answered by a live person 24/7. Crews are background-checked and uniformed. The license number is on every page, and every crew member is verified before they arrive at your Sunnyvale home.
Our Bathroom Remodeling Services in Sunnyvale
Full Bathroom Remodeling
A full bathroom remodel in Sunnyvale starts at $9,000 and runs to $28,000 for high-end work with custom millwork, architectural glass, and specialty finishes. On the 6,000-7,500 sq ft lots that dominate Sunnyvale’s 1950s-1970s neighborhoods, space is tight and the schedule is driven by long-lead items, not labor. We order the Kohler or Toto fixture set, the Cambria or Caesarstone vanity top, and the frameless glass enclosure eight to twelve weeks out, then lock the scope and allowances in writing before anything ships. That discipline - Clause 1 of The Haven Standard - keeps the draw schedule predictable and the homeowner informed.
Walk-In Showers & Shower Remodeling
Walk-in shower installation in Sunnyvale runs $4,500-$12,000. The 1950s ranch homes we see along Mathilda Avenue and past the Caltrain corridor often have original fiberglass or tile surrounds with failing membranes. We strip to studs, inspect the subfloor and any load-bearing walls, and specify the Schluter or Wedi waterproofing system before tile goes up. For homeowners aging in place or planning to, we can spec curbless entries with linear drains, though these require precise slab work on the shallow foundations common to this stock.
Frameless Glass Shower Enclosures
Frameless glass is the item that most often slips a Sunnyvale schedule. The glass is templated only after tile is set and cured, then fabricated to measure - typically a 3-4 week turn. On a recent job near the Middlefield-Ellis-Whisman corridor, our tech ordered the Kohler fixture set and the Cambria vanity top eight weeks out, locked the scope in writing, and kept the frameless enclosure from becoming the critical path. The result: punch list closed after city inspection sign-off, no rush charges, no surprises.
Tub-to-Shower Conversion
Converting a tub to a shower in Sunnyvale runs $3,500-$10,000. Many original 1960s bathrooms have steel tubs with integrated surrounds and cast-iron drains that don’t align with modern shower valves. We map the existing waste line, check for adequate slope to the main, and specify the conversion before demolition starts. In homes near the Superfund corridor, any drain relocation triggers soil vapor intrusion protocols - a condition we flag in the written scope, not after the tile is off.
Vanities, Tile & Fixtures
Bathroom vanity installation runs $800-$3,000 depending on size and finish. We source KraftMaid and Wellborn cabinets through our fifty-plus vetted brand list, which keeps the written quote honest rather than inflated. Tile work - porcelain, ceramic, or natural stone - is priced by square foot with the membrane and prep broken out separately. You’ll see every line item before work starts.

Common Bathroom Remodeling Problems We See in Sunnyvale Homes
- Original slab without vapor barrier. We tore out a 1962 ranch bathroom near the Middlefield-Ellis-Whisman corridor and found no vapor barrier beneath the slab. Our crew segregated the contaminated spoils per city protocol before the rough-in could proceed. Contractors who’ve only worked in Cupertino or Mountain View routinely miss this condition.
- Long-lead designer items ordered late. A frameless glass enclosure or custom vanity ordered after demolition can push the job past the winter wet-season window. We lock the material schedule in writing before tear-out starts.
- Subfloor rot hidden behind original tile. The marine layer off the Bay keeps crawlspace and slab-edge moisture high in Sunnyvale. We inspect the subfloor during the initial walkthrough and specify sistering or replacement in the original scope, not as a mid-job discovery.
- Load-bearing walls in the way of the desired layout. Many Sunnyvale ranches have simple roof structures where interior walls carry load. We verify structure before quoting, so the price for moving a wall is in the original number, not a change order later.

FAQs - Bathroom Remodeling in Sunnyvale
Yes. Any bathroom remodel that moves or adds a drain line in this area can trigger soil vapor intrusion protocols and city-required vapor barriers, even on a small interior job. Contractors who only work in Cupertino or Mountain View routinely miss this. The fix - a vapor barrier and restricted-spoil disposal plan - belongs in the permit set before demolition starts. We flag this condition during our initial walkthrough and price it into the written scope. Call (669) 259-1843 for an exact quote - estimates are free.
Long-lead items, not labor, set the calendar. A frameless glass enclosure is templated after tile cure, then fabricated to measure - three to four weeks. Custom vanities from KraftMaid or Wellborn run eight to twelve weeks. On tight Sunnyvale lots where winter wet-season compresses exterior work, a late-ordered fixture can push the whole job. We lock the material schedule and allowances in writing before anything ships, so the timeline is fixed when demolition starts. Call (669) 259-1843 for an exact quote - estimates are free.
Often yes, if the existing waste line has adequate slope and the subfloor is sound. Many Sunnyvale ranches have steel tubs with integrated surrounds that come out cleanly, leaving a space we can waterproof and tile for $3,500-$10,000. We verify structure and drainage during the initial walkthrough and specify exactly what stays and what goes in the written scope. If the drain needs relocation near the Superfund corridor, we include the vapor barrier protocol in the original price. Call (669) 259-1843 for an exact quote - estimates are free.
The city permit covers plumbing, electrical, and structural changes, plus Title 24 energy compliance for any new lighting or ventilation. For jobs near the Superfund corridor, the permit set must also include the soil vapor barrier plan and restricted-spoil disposal documentation. We pull permits as standard practice, include the cost in the written quote, and schedule inspections so the job doesn’t sit idle waiting for sign-off. Call (669) 259-1843 for an exact quote - estimates are free.
Under The Haven Standard, no work proceeds on a change until the change order is signed. We prevent the need for most changes by inspecting before we quote - subfloor, structure, slab condition, and any soil vapor protocols - then locking the scope and allowances in writing. The discipline that has kept our projects within a few percent of the agreed cost across 4,000-plus jobs is the same discipline we bring to every Sunnyvale bathroom. Call (669) 259-1843 for an exact quote - estimates are free.
