We’ve worked on enough 1950s and 1960s ranch homes along El Camino Real and around Washington Park to know the routine: original cast-iron drain in a slab-on-grade floor, a 100-amp panel that was fine for 1962, and a bathroom footprint that hasn’t changed since Eisenhower was president. Sunnyvale’s housing stock rewards contractors who understand what’s under the tile before they quote the job.

Why Rowan Construction Group Cupertino Is Sunnyvale’s Preferred Bathroom Remodeling Company

Our Bathroom Remodeling team has 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 specifically, we’ve learned to scope for what other contractors miss: the county drainage inspection that runs parallel to city building permits, the engineered slab patch that follows a cast-iron drain replacement, and the Title 24 energy report that triggers when valuation crosses the threshold.

Customers here read the three-star reviews before they call, and they want the price range on the page before they make contact. We put it in writing. Under Clause 1 of The Haven Standard, the quote is a flat price with a written scope and a written warranty. No “call for a quote” - that phrase doesn’t exist in our process.

Our technicians 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, not an asterisk.

Our Bathroom Remodeling Services in Sunnyvale

Full Bathroom Remodeling

A full gut renovation in Sunnyvale means dealing with what sits beneath the finishes. On a 1,400 sq ft ranch near Washington Park, we tore out a 1954 hall bath down to original cast-iron drain in the slab, found the pipe scaling at the wye, and had to call for a county side-sewer/drainage inspection before we could pour back the engineered patch. We pulled the city building and Title 24 permits, ordered the KraftMaid vanity and Kohler fixtures against a written allowance, and the crew walked the punch list with the homeowner before framing inspection sign-off. That’s the sequence we now plan for on every Sunnyvale ranch built before 1975.

Walk-In Showers & Shower Remodeling

Walk-in shower installation in Sunnyvale runs $4,500-$12,000. The price climbs when we’re breaking slab to reroute a drain from a tub footprint to a curbless shower pan, because that slab break triggers Santa Clara County’s expansive clay review and a full engineered foundation detail. The city handles your building and Title 24 permits, but the county pulls drainage and foundation permits separately. Two inspection sign-offs on one slab break. We scope both in the written quote so you’re not learning about the second permit after demo starts.

Tub-to-Shower Conversion

Tub-to-shower conversion in Sunnyvale costs $3,500-$10,000. The lower end covers a direct swap with surface plumbing. The upper end covers what we find in the Lakewood and Ponderosa neighborhoods: original 1950s cast iron, a slab that has to come up, and a county drainage review before the new pan goes in. We quote for the full scenario and credit back if the slab stays intact. That’s how we’ve kept projects within a few percent of the agreed price across 4,000-plus jobs.

Vanities, Tile & Fixtures

Vanity installation runs $800-$3,000 depending on whether we’re hanging a stock cabinet or running plumbing through a slab for a floating double vanity. For tile, we spec Schluter or Laticrete membrane systems and explain why in the quote - Sunnyvale’s expansive clay soils transmit stress through the slab, and a bonded membrane outperforms traditional mud beds on post-tension or engineered patches. We source Kohler and Toto fixtures through our vetted supply chain, which keeps the written allowance honest rather than inflated.

Small Bathroom Remodels

Small bathroom remodels in Sunnyvale start at $5,000 and run to $12,000. The compact footprint doesn’t eliminate the underlying conditions - it compresses them. A 5×7 hall bath still has the same cast-iron drain, the same 100-amp panel, and the same single-pane aluminum window as the master. We scope for the full package so a “simple refresh” doesn’t become a change-order conversation mid-project.

Trusted Brands We Service in Sunnyvale

We maintain supply relationships across fifty-plus vetted brands, which lets us quote real numbers instead of placeholders. For Sunnyvale bathroom projects, we regularly specify KraftMaid and Wellborn cabinetry, Cambria and Caesarstone countertops, and Kohler and Toto fixtures. Our local supply house on the Peninsula stocks common configurations with turnaround times that keep renovation schedules intact. When a customer wants a specific finish or a custom size, we document the lead time in the written scope - no surprises when the cabinet truck is two weeks out.

Common Bathroom Remodeling Problems We See in Sunnyvale Homes

• Cast-iron drain scaling in slab-on-grade floors. The original 1950s plumbing in Sunnyvale ranch homes corrodes from the inside. We scope a camera inspection on every pre-1975 bath so we know if we’re cutting concrete before we quote the concrete cutting.
• Undersized electrical panels triggering upgrade requirements. A new vanity GFCI, heated floor, or vent fan can push a 100-amp panel over capacity. We check the panel and the load calculation during the estimate, not during rough-in inspection.
• Single-pane aluminum windows failing Title 24 envelope requirements. Once a bathroom remodel crosses certain valuation thresholds, the city requires energy compliance that the original windows won’t meet. We flag this in the written scope so the window allowance is real.
• Expansive clay soil movement under slab breaks. Sunnyvale’s Bay Area alluvial soils shift seasonally. A slab break without an engineered patch detail can settle, crack the new tile, and void the warranty. We spec the patch and pull the county permit for it.
