AfterFast, Reliable Bathroom Remodeling Across Sunnyvale
Bathroom remodeling in Sunnyvale typically runs $9,000-$28,000 for a full gut renovation, with most projects taking 3-6 weeks from permit to final inspection. Our crews serve Sunnyvale from our Bay Area dispatch office, and we carry the specifications for Sunnyvale’s all-electric reach codes alongside standard California Title 24 requirements. Call (669) 271-8644 to schedule your free written estimate - every quote includes a line-item scope, a documented photo record, and our 365-Day Done Right Promise printed in plain terms.
We know the Lakewood and Cherry Chase ranch corridors well. Those 1950s-1970s slab-on-grade homes south of El Camino Real hold land values of $1.5M-$2.5M+ while their original galvanized drains and 100A panels remain. That’s why our Bathroom Remodeling team starts every Sunnyvale project with a drain plan and electrical load check, not a tile sample. The finish work comes after the infrastructure is verified.

Our Bathroom Remodeling Services in Sunnyvale
Full Bathroom Remodeling
A full bathroom remodel in Sunnyvale’s older ranch stock often becomes a gut renovation once we open the walls. The original galvanized drains, 100A panels, and minimal insulation in these 1,200-1,800 sq ft homes frequently trigger full MEP replacement - mechanical, electrical, plumbing - to meet current code. We price this possibility into the initial written quote using allowances based on what we’ve found in similar homes. Under Clause 1 of The Haven Standard, that written price is delivered before any work starts, and no change proceeds without a signed change order. This is the administrative discipline that has kept our projects within a few percent of the agreed cost across 4,000-plus jobs.
Walk-In Shower Installation
Walk-in shower installation in Sunnyvale runs $4,500-$12,000 depending on whether we’re working within the existing slab footprint or relocating drains. In Lakewood and Cherry Chase ranches, moving a shower drain means jackhammering the slab and an engineered re-route - not optional, and not something to discover mid-demo. We verify the drain path during our first site visit and note it in the written scope. Our field team sources Kohler and Toto valves with Moen trim kits from our fifty-plus vetted brand list, and we confirm subfloor condition before tile selection.
Tub-to-Shower Conversion
Tub-to-shower conversion in Sunnyvale costs $3,500-$10,000 and is one of our most requested services in these aging ranches. The original tubs sit on slab with drains that may be galvanized, improperly sloped, or simply in the wrong position for a modern walk-in shower. We evaluate whether the existing drain can serve the new fixture or requires relocation - a distinction that changes the permit pathway and the price. Our crew on a 1962 Cherry Chase ranch handled exactly this: pulled permits for drain relocation and subfloor repair, replaced galvanized with ABS, and set a Kohler valve with Moen trim. The punch list cleared at inspection sign-off in one visit.
Vanities, Tile & Fixtures
Vanity installation runs $800-$3,000 in Sunnyvale, with tile and fixture allowances added to the overall project scope. We specify moisture-resistant backer board and waterproof membrane - Schluter or equivalent - because these slab-on-grade homes lack the crawl-space ventilation that allows other structures to breathe. Tile selection without confirming subfloor condition is a common mistake here; old slabs often have soft spots or failing galvanized lines that must be addressed before any finish work begins. Our written quote includes an allowance for subfloor repair so the number doesn’t balloon when rough-in reveals hidden conditions.
Small Bathroom Remodels
Small bathroom remodels in Sunnyvale range $5,000-$12,000, but the tight footprint of these 1950s-1970s homes can complicate what seems simple. A 5×7 powder room with the toilet drain in the wrong place for a modern layout may require the same slab work as a full bath. We photograph existing conditions during our first visit and note potential slab, drain, or panel issues in the written scope. The customer leaves with evidence of what we found and what we priced - before anyone picks up a tool.

AfterTrusted Brands We Service in Sunnyvale
We source across fifty-plus vetted brands, giving our written quotes honest numbers rather than inflated ones. For Sunnyvale bathroom projects, we regularly specify Kohler and Toto fixtures, KraftMaid and Wellborn vanities, and Cambria or Caesarstone for vanity tops where the customer wants stone. Our relationships with these suppliers mean we don’t mark up material costs to cover unknowns - the unknowns are identified and priced in writing before work begins. For window replacement that often accompanies bathroom remodels in these older homes, we carry CGI, CWS, and ES Windows specifications, with ECO Window Systems available for energy-code upgrades. Local parts availability keeps timelines predictable, and our documented photo record on every visit means you see what arrived and what was installed.
Common Bathroom Remodeling Problems We See in Sunnyvale Homes
- Slab drain relocation without permits or engineering. In Lakewood and Cherry Chase ranches, moving a shower drain requires jackhammering the slab and an engineered re-route. Skipping this step means inspection sign-off failure and costly rework after rough-in - we’ve been called in to fix this exact mistake on other contractors’ jobs.
- Tile and fixtures selected before subfloor verification. Old slab-on-grade homes in Sunnyvale often hide soft spots or failing galvanized lines beneath seemingly sound flooring. We verify substrate condition before any finish selection, and our written quote includes an allowance for repair.
- No written allowances for hidden conditions. A modest small bathroom remodel can balloon when rough-in reveals slab repair needs. Our quotes include line-item allowances based on what we’ve found in comparable homes - under The Haven Standard, no change proceeds without a signed change order, so the customer controls whether to proceed.
- Electrical panels undersized for modern loads. Original 100A panels in these 1950s-1970s homes can’t support heated floors, tankless electric water heaters, and multiple GFCI circuits. We evaluate panel capacity during our first visit and note any upgrade requirement in the written scope.

FAQs - Bathroom Remodeling in Sunnyvale
Original 1950s-1970s bathrooms in these homes were built with slab-on-grade plumbing and galvanized drains, so any permitted remodel that relocates a shower drain requires jackhammering the slab and an engineered re-route. We start every Lakewood project with a drain plan, not a tile selection, and we pull permits for the relocation before demo begins. Call (669) 271-8644 to schedule a site visit - estimates are free.
Yes - Sunnyvale’s reach codes eliminate natural gas rough-in from new residential construction and major additions, so any bathroom remodel that triggers the “major addition” threshold must use electric water heating and space heating specifications. Our crews carry different spec sets for Sunnyvale, Santa Clara, and Cupertino because neighboring jurisdictions enacted these bans on different schedules or not at all. We verify which code pathway applies during permitting and note it in your written scope. Call (669) 271-8644 for clarification on your specific project.
A typical small bathroom remodel in Sunnyvale runs $5,000-$12,000, with most falling in the $7,000-$9,000 range for straightforward fixture replacement within existing drain locations. Slab work, panel upgrades, or drain relocation push costs higher. Our written quote includes line-item allowances for hidden conditions based on what we’ve found in comparable homes. Call (669) 271-8644 for an exact quote - estimates are free.
We evaluate panel capacity during our first site visit and note any upgrade requirement in the written scope before work begins. A 100A panel typically cannot support heated floors, tankless electric water heaters, and multiple GFCI circuits simultaneously. If an upgrade is needed, we price it as a line item with a permit pathway included - not as a surprise mid-project. Call (669) 271-8644 to schedule an electrical evaluation with your bathroom estimate.
Usually yes - tub-to-shower conversion in these ranches is often a fixture-and-drain swap within the existing footprint, running $3,500-$10,000. The question is whether the existing drain location and slope work for the new shower pan, or whether relocation is needed. We verify this with a camera inspection during our first visit and note the finding in the written scope. Our Cherry Chase field project followed exactly this path: drain relocation required, slab opened, ABS installed, Kohler valve set, inspection passed on first visit. Call (669) 271-8644 to check your drain configuration.
