Fast, Reliable Bathroom Remodeling Across Sunnyvale
Bathroom remodeling in Sunnyvale runs $9,000-$28,000 for a full renovation, with most projects taking 4-8 weeks once permits clear and long-lead items are on site. We dispatch crews from our San Francisco Bay Area office and serve Sunnyvale homes directly, from Birdland ranches to Lakewood Village rebuilds. Call (650) 405-3637 to schedule your free estimate with a written price before any work starts.
Our Bathroom Remodeling team has worked the specific housing stock that defines this city: 1950s-1970s tract ranches with original hall baths, late-1970s-1980s homes on post-tensioned slabs, and the growing number of teardown-rebuilds where master-suite bathrooms are designed into ground-up custom construction. We know the Sunnyvale Building Division’s CalGreen Tier 1 requirements, the cable-locating protocols for slab work, and the fixture certifications that keep permits moving. That local fluency is what keeps our projects within a few percent of the written price we quote upfront.
Why Rowan Construction Group Sunnyvale Is Sunnyvale’s Preferred Bathroom Remodeling Company
We’ve delivered 4,000-plus 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 in most markets because the compliance layer here is thicker: CalGreen Tier 1, Title 24 energy reports, and water-conserving fixture certifications are mandatory, not optional. Out-of-county contractors get stalled by these requirements regularly. We build them into the initial quote and submit them correctly the first time.
Our crews are background-checked and uniformed; a live person answers calls 24/7. Every visit includes a documented photo record as standard, not an upgrade. Under our 365-Day Done Right Promise, backed by The Haven Standard, if it is not done right, we make it right - the guarantee is printed on every page and backed by a terms page, not an asterisk.
We also offer a Free Second Opinion on any written estimate: bring a competitor’s quote and we will review it line by line at no charge. For Bathroom Remodeling in Sunnyvale homeowners researching contractors the way they research appliances, that transparency is the point.
Our Bathroom Remodeling Services in Sunnyvale

Full Bathroom Remodeling
A full bathroom remodel in Sunnyvale means different things depending on the vintage of your home. In a 1960s Birdland ranch, it often means gutting to studs, addressing subfloor damage from decades of moisture, and resequencing the work so custom millwork arrives before drywall - not after tile, which is how production crews schedule it. In a teardown-rebuild on the same street, the master suite is designed into the architectural plans from the start, and our role shifts to finish carpentry, fixture specification, and the CalGreen compliance documentation that gets the certificate of occupancy issued. Either way, the price is fixed in writing before we order materials.

Walk-In Showers & Shower Remodeling
Walk-in shower installation in Sunnyvale runs $4,500-$12,000, and it is the most common request we see in ranch-home renovations. The 1950s-1970s stock typically has 32″ x 60″ fiberglass tub-shower combos with failing surrounds; we remove them, reframe for zero-threshold or low-threshold entries, and waterproof with liquid-applied membranes (redgard or equivalent) that we document in the photo record. For homes on post-tensioned slabs - common in late-1970s-1980s Sunnyvale construction - we scan for cables before any floor penetration. Cutting without scanning can sever a cable and convert a bathroom remodel into a structural repair.

Tub-to-Shower Conversion
Tub-to-shower conversion in Sunnyvale costs $3,500-$10,000 and makes sense when the existing tub is unused and the footprint is tight. We see this frequently in Lakewood Village homes where original pink or harvest-gold cast-iron tubs still occupy 5′ alcoves. The conversion requires rethinking the drain location (often from end-drain to center-drain), which again triggers the slab-scan protocol on post-tensioned homes. We handle the permit, the Title 24 compliance, and the fixture certifications that Sunnyvale requires.

Vanities, Tile & Fixtures
This is where Sunnyvale’s high-end market shows. Custom vanities from KraftMaid or Wellborn, Cambria or Caesarstone counters, and Kohler or Toto fixtures are standard requests in our pipeline. The lead times, not the labor, set the calendar: custom cabinetry runs 6-10 weeks, imported tile 4-8 weeks, and frameless glass enclosures 3-5 weeks. We sequence these orders against the permit timeline so nothing sits in a warehouse while inspections stall. Under Clause 1 of The Haven Standard, the written price covers the specified brands and grades; if you upgrade during the job, the change order is signed before the new order is placed.

Frameless Glass Shower Enclosures
Frameless glass shower enclosures in Sunnyvale range $3,000-$8,500 and are specified on nearly every master-suite job we do. The glass is 3/8″ or 1/2″ tempered, with brushed nickel or matte black hardware depending on the fixture package. We measure after tile is set, not before, because the actual dimensions determine the cut. Rush glass orders carry a 30-40% premium, which is why we include the measurement and fabrication window in the written schedule.

Small Bathroom Remodels
Small bathroom remodels in Sunnyvale - powder rooms, hall baths under 40 square feet - run $5,000-$12,000. The constraint is spatial, not budgetary: every decision is forced by clearances (15″ from centerline to side wall for a toilet, 21″ minimum in front of the bowl). In older ranches with original 5′ x 7′ layouts, we often relocate the door swing or convert a swing door to a pocket door to reclaim usable space. The permit is simpler but still requires CalGreen fixture certification.

Common Bathroom Remodeling Problems We See in Sunnyvale Homes

- Failed subfloors beneath original tile. We were called to a 1960s ranch in Birdland where the hall bath had been tiled over a failed subfloor; the plywood had delaminated from decades of moisture migration. We stripped to joists, sistered where needed, and rebuilt with cement backerboard and a liquid-applied membrane before setting new tile.
- Post-tension cables in the slab path. Before we cut for the new shower drain in that same Birdland job, we scanned for post-tension cables and found them running through the planned rough-in. We re-engineered the drain location around the cable zone, then rebuilt the bath as a walk-in shower with frameless glass and a KraftMaid vanity, with Cambria quartz counters and Kohler fixtures - all fixed in writing before we ordered.
- Permit delays from incomplete CalGreen submissions. Sunnyvale Building Division enforces strict CalGreen Tier 1 compliance and requires a separate Title 24 energy compliance report even for modest additions. Missing EV-ready conduit, solar-ready roof penetrations, or water-conserving fixture certifications can add weeks to the permits timeline and 3-5% to cost. We submit complete packages upfront.
- Foundation movement cracking tile and grout. The valley floor beneath Sunnyvale is underlain by expansive Bay clay and fill soils that shrink during the dry season and heave when winter rains return. In older bathrooms, this movement telegraphs through slab cracks that reopen grout joints and fracture floor tile. We specify crack-isolation membranes and flexible grouts, and we flag when an engineer’s assessment is warranted before we guarantee the finish.

FAQs - Bathroom Remodeling in Sunnyvale

Custom-millwork vanities from KraftMaid or Wellborn run 6-10 weeks from order to delivery, and the cabinet box dimensions determine rough plumbing locations, mirror sizing, and sometimes door swing clearances. In Birdland teardown-rebuilds and gut remodels where every wall is opened, we sequence cabinetry before drywall so the install is precise and the finish carpentry is protected. The crew is ready; the calendar waits on the millwork. Call (650) 405-3637 to lock your place in the production queue - estimates are free.
Yes. Homes built in Sunnyvale from the late 1970s through the 1980s frequently sit on post-tensioned concrete slabs with tensioning cables running through the concrete matrix. Cutting or coring without a cable-locating scan can sever a cable, compromising the structural slab and converting a bathroom remodel into a repair that requires an engineer and a permit amendment. We scan as a standard pre-construction step, not a surprise add-on. Call (650) 405-3637 to schedule - estimates are free.
It adds 3-5% to project costs and requires specific documentation: a Title 24 energy compliance report, EV-ready conduit, solar-ready roof penetrations, and water-conserving fixture certifications (1.28 gpf toilets, 1.5 gpm faucets). Submitted correctly upfront, these add no time to the schedule. Submitted incorrectly or treated as afterthought paperwork, they can stall permits by weeks. We budget and submit these in every Sunnyvale quote. Call (650) 405-3637 for a line-item breakdown - estimates are free.
We specify crack-isolation membranes beneath floor tile and flexible epoxy grouts that tolerate minor differential movement. Where slab cracking is active or structural, we flag it in the photo record and recommend an engineer’s assessment before we guarantee the finish. The expansive Bay clay beneath Sunnyvale shrinks in dry season and heaves with winter rains; we have seen the pattern across enough jobs to know when a membrane is sufficient and when the foundation needs attention first. Call (650) 405-3637 to discuss your specific condition - estimates are free.
Yes, and it typically saves 15-25% by avoiding plumbing relocation, structural changes, and the permit amendments that both trigger. Keeping the toilet, vanity, and wet-wall in place allows the budget to shift to finish quality: Cambria counters, Kohler Purist fixtures, frameless glass, and custom millwork. The tradeoff is spatial; a 5′ x 7′ hall bath with original layout remains a 5′ x 7′ hall bath. We will model both options in the written quote so you can compare. Call (650) 405-3637 - estimates are free.
