Why Rowan Construction Group Mountain View 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 most places - this is a charter city with its own building department and plan-check staff, separate from Santa Clara County, and the permit volume here is intense. Our team knows the Sunnyvale municipal process, from rough-in inspection scheduling to final sign-off, because we’ve navigated it repeatedly in neighborhoods like Lakewood and Cherry Chase.

Our customers here tend to be tech-sector homeowners who bought between 2015 and 2025 and research contractors the way they research appliances - reading the three-star reviews, wanting numbers they can screenshot. We give them those numbers. Under Clause 1 of The Haven Standard, the price is written before anyone starts. No exceptions.

Background-checked, uniformed technicians arrive with a documented photo record included as standard, not an upgrade. A live person answers calls 24/7. And our 365-Day Done Right Promise - if it’s not done right, we make it right - is printed on every page, backed by terms, not an asterisk.

Our Bathroom Remodeling Services in Sunnyvale

Full Bathroom Remodeling

A full bathroom remodel in Sunnyvale almost always starts with the slab, not the tile. The 1950s-1970s ranch homes that dominate Birdland, Lakewood, and Cherry Chase sit on slab-on-grade construction over expansive alluvial clay that swells and shrinks with the seasons. We laser-level and self-level the subfloor before any tile or shower pan goes down - because grout and pans set directly over cracked or out-of-level concrete fail within a few years. Our full remodels include rough-in updates to PEX supply and PVC drain, shear-wall upgrades where walls are opened, and electrical service evaluation against Silicon Valley Power requirements. The written quote breaks out each line item: slab prep, framing, mechanical, finish.

Walk-In Showers & Shower Remodeling

Walk-in shower installation in Sunnyvale runs $4,500-$12,000, with frameless glass enclosures and Schluter-Kerdi waterproofing membranes as our standard specification. The mild, nearly frost-free climate here means year-round construction, but it also means waterproofing failures stay hidden longer - we often find them during pre-remodel inspections when homeowners are preparing to sell. We specify marine-grade finishes and sealed joints on all hardware, and we verify that the existing electrical panel can handle added loads like body sprays or heated floors before we quote. SVP, not PG&E, controls electrical service in most of Sunnyvale, and their inspection timeline and submittal requirements catch out-of-town contractors off guard. We don’t get caught off guard.

Tub-to-Shower Conversion

Tub-to-shower conversion in Sunnyvale costs $3,500-$10,000 and addresses one of the most common requests we hear: removing a 1960s cast-iron tub that sits on a cracked, out-of-level slab. In Birdland, we tore out a 1962 ranch hall bath down to studs and found the slab had cracked across the drain line, leaving the original tub out of level by nearly half an inch over four feet. We brought the load-bearing wall framing up to current shear requirements while the walls were open, re-rough-in’d the drain and supply in PEX, self-leveled the slab, and set a Schluter-Kerdi shower pan with a frameless glass enclosure and Kohler fixtures. The homeowner’s pre-sale inspection had flagged the hidden leak, and the inspection sign-off cleared the whole scope before we closed the walls. That’s the documented record we deliver.

Vanities, Tile & Fixtures

Vanity installation in Sunnyvale - whether KraftMaid, Wellborn, or another brand from our fifty-plus vetted supplier list - runs $800-$3,000 depending on size, plumbing relocation, and electrical for lighting or outlets. We specify cabinet boxes with plywood construction, not particleboard, because the seasonal humidity swing in valley-floor homes stresses inferior materials. Tile selection gets the same engineering-first treatment: we recommend porcelain over ceramic for floor applications, with crack-isolation membrane over any slab showing movement history. The fixtures we quote are Kohler and Toto, with brass valve bodies, not plastic, because the replacement cost of a failed valve behind finished tile exceeds the upfront savings tenfold.

Trusted Brands We Service in Sunnyvale

Our supplier depth across fifty-plus vetted brands means the written quote carries honest numbers, not inflated ones. For Bathroom Remodeling in Sunnyvale, we regularly specify KraftMaid and Wellborn cabinets, Kohler and Toto fixtures, and Schluter waterproofing systems - all stocked through regional distribution with turnaround times that keep Sunnyvale projects on schedule. We don’t upsell to premium brands when standard specifications will perform; we document why a specification is chosen, and the customer sees that documentation in the written scope. That’s the Haven Standard.

Common Bathroom Remodeling Problems We See in Sunnyvale Homes

• Tile and shower pans set directly over cracked slab-on-grade. In Birdland and Lakewood ranches, we regularly find previous remodels where tile was laid over unlevel concrete without self-leveling compound or crack-isolation membrane. Grout cracks within two to three years. The pan fails. We fix the slab first, every time.
• Unpermitted rough-in changes hidden behind new tile. No third-party inspector confirms drain slope, supply pressure, or vent configuration before walls close. We pull permits for every project, schedule Sunnyvale’s municipal inspections, and don’t close walls until sign-off is documented.
• Undersized 100A electrical panels left in place during remodels that add load. A body-spray shower, heated floor, and required GFCI circuit can push an original panel past capacity. We evaluate panel capacity during quoting, because tripping the job at SVP electrical sign-off is expensive and avoidable.
• Galvanized supply plumbing still in service behind new finishes. Many Sunnyvale ranches never had supply lines updated from original galvanized. We replace with PEX during rough-in, with full-pressure testing documented before close-in.
