Why Rowan Construction Group Campbell Is Sunnyvale’s Preferred Bathroom Remodeling Company
We’ve delivered bathroom remodels across Sunnyvale’s dense ranch blocks since 2007, and the repetition matters. When you’ve opened walls in fifty near-identical 1952 slab-on-grade floor plans, you know where the cast-iron waste lines run, which walls carry roof load, and where the previous owner likely buried a non-permitted addition. That familiarity saves time on site and protects your draw schedule from surprises.
Our customers in Sunnyvale leave reviews that mention specifics: the photo record they received at each visit, the signed change order that arrived before any added work, the permit status they could track online. We don’t ask for trust; we document the work and let the record speak. Under Clause 1 of The Haven Standard, the price is written before anyone starts - every time, on every trade.
Response time to Sunnyvale is typically next-day for estimates, with crews already staged in the area on active jobs. We don’t promise same-day dispatch on planned construction work - bathroom remodels aren’t emergencies, and anyone who tells you otherwise is selling theater, not carpentry. What we do promise is a flat written quote with line-item scope, a 365-Day Done Right Promise backed by terms you can read, and a crew that arrives in uniform with background checks already complete.
Our Bathroom Remodeling Services in Sunnyvale

Full Bathroom Remodeling
A full bathroom remodel in Sunnyvale starts at $9,000 and typically reaches $28,000 for master baths with reconfigured layouts, new wet walls, and upgraded finishes. On these 1950-75 ranch slabs, we often find the original 4-inch cast-iron drain stack and galvanized supply lines - both due for replacement. We pull permits through Sunnyvale’s Community Development department, coordinate inspection sequences, and handle the party-wall notice if your wet wall shares framing with the neighbor. The quote includes all of this; nothing gets added after the fact without a signed change order.

Walk-In Showers & Shower Remodeling
Walk-in shower installation in Sunnyvale runs $4,500-$12,000 depending on whether we’re working within the existing footprint or moving drain rough-in. We set Kohler and Toto bases with proper pre-sloped mortar beds or Schluter-Kerdi membrane systems - the membrane is a waterproofing layer that prevents the subfloor rot we see in original construction where builders relied on mud-set tile alone. Frameless glass enclosures from local suppliers install once tile and grout cure; we measure twice and fabricate to field conditions, not assumptions.

Tub-to-Shower Conversion
Tub-to-shower conversion is our most frequent request in Sunnyvale ranch homes, priced at $3,500-$10,000. The original tub alcove is usually 60 inches wide with a window in the back wall - a detail that demands careful waterproofing around the sill. We remove the tub, cap or reroute the waste line, and install a curbed or curbless shower depending on your preference and the slab condition. On one Birdland job, we opened a hall bath and found a non-permitted 1990s addition that had shifted the drain rough-in and left the subfloor out of level. We pulled a corrected permit, re-ran the waste line, poured a self-leveling patch, and set a Kohler shower base with frameless glass, then worked a party-wall notice with the neighbor before framing the new wet wall. The job cleared inspection sign-off after we documented the existing conditions and issued a change order for the added framing and structural tie-in.

Vanities, Tile & Fixtures
Vanity installation in Sunnyvale ranges $800-$3,000, with tile and fixture packages layered on top. We source KraftMaid and Wellborn cabinets, Cambria and Caesarstone countertops, and Kohler or Toto fixtures - brands we vet for warranty support and parts availability in the Bay Area. Small bathroom remodels, common in these 5-by-8-foot original layouts, run $5,000-$12,000 and focus on maximizing function without moving walls: a floating vanity, a pocket door, a large-format tile that reduces grout joints and visual clutter.

Common Bathroom Remodeling Problems We See in Sunnyvale Homes

- Unpermitted additions buried in walls. On these dense ranch blocks, previous owners often enclosed carports, added bathrooms without permits, or shifted drain lines in ways that don’t appear on any city record. We document existing conditions with photos before demolition, but when we find shifted rough-in or non-compliant framing, the permit path changes and so does the scope - always with a signed change order before added work proceeds.
- Zero staging room on tight lots. A standard 6,000-square-foot Sunnyvale lot with a detached garage leaves nowhere to park a materials bin or stage tile pallets. We coordinate just-in-time deliveries, use compact debris haulers, and schedule around street-sweeping days to avoid citations. Neighbor relations are part of the project plan.
- Party-wall vibration and damage claims. Shared framing in these slab-on-grade blocks means demo vibration can crack the neighbor’s plaster or loosen their tile. We photograph the adjoining wall surface before we start, install vibration isolation where possible, and carry documentation that protects both parties if a claim arises.
- Liquefaction-zone foundation concerns on the northwest edge. Homes near Highway 237 and the bay marshlands may need geotechnical review before we move walls or add weight. We flag this in the initial walkthrough and build any required soils report into the permit timeline upfront, not as a mid-project surprise.
Pricing for Bathroom Remodeling in Sunnyvale, CA
Here’s what bathroom remodeling costs in Sunnyvale’s current market. Every range below is a flat written quote with scope, not an estimate that shifts once work starts:
| Service | Price Range in Sunnyvale |
|---|---|
| Bathroom Remodel | $9,000-$28,000 |
| Small Bathroom Remodel | $5,000-$12,000 |
| Walk-In Shower Installation | $4,500-$12,000 |
| Tub-to-Shower Conversion | $3,500-$10,000 |
| Bathroom Vanity Installation | $800-$3,000 |
What moves you within these ranges? Moving the toilet or shower drain adds plumbing rough-in and concrete cutting on a slab. Custom tile patterns with natural stone or large-format porcelain cost more per square foot and demand longer install time. Frameless glass enclosures require precise field measurement and local fabrication. Permit complexity in Sunnyvale - especially party-wall review or liquefaction-zone soils reports - adds administrative time we quote explicitly, not bury in overhead.
Bring us any competitor’s written estimate and we’ll review it line by line at no charge. Our Free Second Opinion is standing policy - Clause 1 of The Haven Standard means the price is written before anyone starts, always, and we welcome the comparison.

FAQs - Bathroom Remodeling in Sunnyvale

Yes, Sunnyvale requires a building permit for any bathroom remodel that moves fixtures, alters walls, or modifies plumbing or electrical systems. Cosmetic updates - tile over tile, vanity swap, fixture replacement in the same location - may not trigger permit, but most ranch-home remodels involve enough scope that we pull permits as standard practice. We handle the application, plan check, and inspection scheduling; the permit cost is line-itemed in your written quote. Call (831) 704-1211 and we’ll confirm what your specific project requires during the free estimate walkthrough.
A party wall - shared framing between your home and your neighbor’s - requires notice and sometimes a signed access agreement before we demo or frame new structure against it. In Sunnyvale’s dense ranch blocks, this is common, not exceptional. We photograph the neighbor’s interior wall surface before we start, deliver formal notice per city requirements, and build any needed structural tie-in into the scope and price from day one. The documentation protects everyone if vibration causes plaster cracking or other claims.
Yes, tub-to-shower conversion is one of our most frequent requests in Sunnyvale’s 1950-75 ranch stock, typically priced at $3,500-$10,000. The 60-inch tub alcove is usually standard width, and the slab construction means we cut concrete to reroute drain lines if needed. Window placement in the back wall - common in these floor plans - requires careful waterproofing at the sill. We assess the slab condition, drain location, and any prior unpermitted modifications during the estimate visit, then quote the full scope in writing.
Sunnyvale limits construction noise to 7:00 a.m.-7:00 p.m. weekdays and 9:00 a.m.-5:00 p.m. Saturdays, with no work permitted Sundays or city holidays. We schedule demolition and loud phases within these windows, coordinate material deliveries to avoid early-morning truck noise, and brief crews on parking restrictions that vary by neighborhood. On tight lots where street parking is the only option, we map the schedule around street-sweeping days to avoid citations that delay the job.
A full bathroom remodel in Sunnyvale costs $9,000-$28,000, with small bathroom updates at $5,000-$12,000 and walk-in shower installations at $4,500-$12,000. These ranges reflect current Bay Area labor and material costs, Sunnyvale’s permit fees, and the specific conditions of local housing stock - slab-on-grade construction, potential unpermitted prior work, and party-wall complexity. Your exact price depends on fixture selections, tile material, and whether we’re working within the existing footprint or moving walls and drains. Call (831) 704-1211 for an exact quote - estimates are free, and the price we write is the price you pay, backed by our 365-Day Done Right Promise.
