San Jose’s housing stock spans Eichler atriums in Sunnyvale-adjacent neighborhoods, 1970s tract homes in Almaden, and newer builds in Evergreen that are now hitting their first major system cycles. What they share is original bathrooms built to yesterday’s efficiency and accessibility standards. We’ve replaced fiberglass tub-shower combos in Willow Glen where the surround had cracked at the seam, converted water-guzzling toilets in Japantown condos to Toto dual-flush units, and installed curbless walk-in showers in Los Gatos Hills homes where aging-in-place had become a priority. Every project started with a written price, a written scope, and a crew that arrived in uniform with background checks already completed.

Our San Jose customers are not impulse buyers. They read the three-star reviews, compare the spec sheets, and want the number on the page before they make contact. We built our process for exactly this homeowner. Under Clause 1 of The Haven Standard, the price is written before anyone picks up a tool. Under Clause 3, no change proceeds without a signed change order. That administrative discipline is why our projects finish within a few percent of the agreed cost, not double or triple it.

What Our Bathroom Remodeling Service Includes

Full Bathroom Remodeling

A full bathroom remodel strips the room to substrate and rebuilds it with new plumbing rough-in, electrical, waterproofing, and finishes. In San Jose, we see this most often in homes built between 1960 and 1990 where the original cast-iron tub, galvanized supply lines, and ungrounded outlets no longer meet code or function. Rowan Construction Group delivers a flat written price covering demolition, haul-away, permit pulling, rough and finish work, and final inspection sign-off. The photo record documents each layer: the condition of the subfloor once the old vinyl is up, the membrane installation before tile goes down, the GFCI test results before we hand over the keys.

Walk-In Showers & Shower Remodeling

Walk-in shower remodeling replaces an existing enclosure with a zero-threshold or low-threshold unit, often with frameless glass and integrated bench seating. San Jose homeowners request this after a slip incident, before an aging parent moves in, or simply because they’re tired of cleaning grout lines in a 3×3 fiberglass stall. We specify Schluter-Kerdi or equivalent waterproofing membrane systems, explain the weep screed function at the pan edge, and show you the slope test before tile sets. Our quotes separate the pan work from the wall work so you see where the waterproofing dollars go.

Tub-to-Shower Conversion

A tub-to-shower conversion removes the existing bathtub and installs a shower base and enclosure in the same footprint, typically $4,130 to $11,800 in the San Jose market. This is the most common aging-in-place modification we perform in Campbell and Saratoga, where single-story ranch homes from the 1960s still dominate. The critical detail is the drain location: if your tub drain is at the end and you want a center-drain shower pan, that requires concrete slab cutting in most San Jose foundations, and we flag it in the written scope before you sign. No surprises, no change orders for “discovered” conditions we should have anticipated.

Vanities

Vanity replacement runs from a straightforward cabinet swap to reconfiguring the entire wet wall when homeowners want double sinks or a floating installation. We source KraftMaid and Wellborn cabinet lines with soft-close hardware and plywood box construction, not particleboard, and we specify the countertop at the same time, Cambria or Caesarstone, so the seam plan and overhang are resolved before demolition day. In smaller San Jose bathrooms, particularly in the original 1,200-square-foot Cambrian Park tracts, we often recommend wall-mounted vanities to reclaim floor space and make the room feel larger without moving walls.

Tile & Fixtures

Tile and fixture selection is where most bathroom budgets drift, and where our written scope provides its greatest value. We specify grout type (epoxy for steam showers, standard Portland cement for dry areas), tile layout pattern with a drawing, and exact fixture models with finish codes. Kohler and Toto are our most-specified lines in San Jose, for availability of parts and consistency of warranty support. The quote includes a tile waste factor based on the pattern complexity, diagonal layouts requiring 15% overage versus 10% for straight stack, so you don’t run short mid-job.

Small Bathroom Remodels

Small bathroom remodeling, typically $5,900 to $14,160, demands more planning per square foot than a master bath because every inch carries functional load. We’ve remodeled powder rooms in downtown San Jose condos where the toilet had to be a 10-inch rough-in, not standard 12-inch, and wet baths in ADUs where the shower floor is the bathroom floor. Our process includes a field measurement with laser level and a reflected ceiling plan showing light locations relative to door swing, so the electrician doesn’t show up to find a joist exactly where the pendant was drawn.

Walk-In Shower Installation

New walk-in shower installation, $5,310 to $14,160, most often occurs in home additions, ADU conversions, or garage conversions where the plumbing rough-in is being installed from scratch. In San Jose’s ADU market, which has accelerated since the 2020 state law changes, we coordinate the shower spec with the overall plumbing design, ensuring the tankless water heater capacity matches the simultaneous demand of kitchen and bath. The Haven Standard requires we document the pressure test and pan flood test with photos, and we provide those images as part of your project record.

Brands We Service for Bathroom Remodeling

We’ve installed and serviced hundreds of Kohler fixtures across San Jose, from the budget-conscious Cimarron line in rental-unit turnovers to the Statement freestanding tub in a Los Altos Hills primary bath. We know their valve cartridge interchangeability, which trim kits fit which rough-in bodies, and we stock the most common replacement parts so a leaking shower doesn’t turn into a two-week wait. Our written quotes specify the exact model number and finish code, brushed nickel versus vibrant brushed nickel, so what arrives matches what you approved.

Toto is our go-to for water-efficient toilets and integrated washlet systems, particularly in the Cupertino and Sunnyvale markets where buyers expect Japanese-brand fixtures. We’ve installed the Aquia dual-flush wall-hung in powder rooms where floor space is minimal, and the Neorest in full remodels where the electrical rough-in for the integrated bidet has to be planned before drywall. Whether you have Kohler, Toto, or any other make, we can source, install, and warranty the work. Our fifty-plus vetted brand relationships mean the written quote contains honest numbers rather than inflated ones, because we know the actual lead times and volume pricing.

Signs You Need Bathroom Remodeling Right Now

• Water damage visible on the ceiling below. A brown stain on the drywall beneath your upstairs bathroom means the waterproofing membrane has failed at the pan or wall junction, or the caulk seal at the tub edge has degraded. In San Jose’s dry climate, homeowners often ignore slow leaks for months, but the subfloor rot and joist damage compound exponentially. We open the ceiling, identify the source with a flood test, and specify the repair in writing before touching tile.
• Grout cracking or tiles sounding hollow when tapped. Hollow tile indicates the thinset bond has failed, usually from installer error, foundation movement, or water intrusion degrading the substrate. In the clay-heavy soils of Almaden Valley and the hills above Saratoga, seasonal expansion and contraction stress tile installations installed without proper movement joints. We assess whether the fix is localized re-tiling or full substrate replacement, and we tell you which before you commit.
• Mold or persistent mildew despite regular cleaning. Surface mold wipes off; recurring mold behind the tile indicates moisture trapped in the wall cavity, almost always from failed grout, missing caulk, or an improperly sloped shower pan. San Jose’s Mediterranean climate means bathrooms without exhaust fans, common in pre-1980 construction, never fully dry. We specify Panasonic or Broan humidity-sensing exhaust fans as standard in every full remodel, ducted to exterior, not just the attic.
• Fixtures original to a home built before 1994. Pre-1994 toilets use 3.5 gallons per flush versus 1.28 for current WaterSense models, and original showerheads flow at 5 gallons per minute versus 1.75 today. For a family of four, that’s thousands of gallons and hundreds of dollars annually. More critically, old fixtures mean old supply lines, often galvanized steel or early copper with pinhole corrosion, and valves that fail catastrophically when disturbed. We replace the stops, supplies, and valves behind every fixture we touch, and we document the before condition.
• The layout no longer fits how you live. A tub you never use, a single sink for two working professionals, a toilet visible from the hallway through a poorly placed door. These are not luxury complaints; they’re daily friction that accumulates. We’ve reconfigured bathrooms in San Jose’s Willow Glen cottages where the only solution was moving the wet wall three feet into the bedroom, and we engineered the structural support and permit path before quoting a dollar. The written scope includes the framing plan, the plumbing reroute, and the inspection sequence so you understand why the project costs what it costs.

Our Bathroom Remodeling Process - Step by Step

1. 1
   On-site measurement and condition assessment. We arrive with laser measure, moisture meter, and inspection camera. We document the existing plumbing configuration, electrical panel capacity, subfloor condition, and any signs of prior water damage or unpermitted work. You receive these photos within 24 hours, before the quote is even written, so you see what we see.
2. 2
   Written scope and flat-price quote delivery. Within 48 hours of the site visit, you receive a line-item quote: demolition and haul-away, rough plumbing, electrical, waterproofing, tile and fixture installation, permit fees, and final inspection. Each line carries a price and a specification. Under Clause 1 of The Haven Standard, this written price is delivered before any work starts, every time, on every trade.
3. 3
   Permit application and material procurement. We pull the building permit with the City of San Jose or appropriate jurisdiction, schedule the required inspections, and order long-lead items like custom vanities or imported tile. You receive the permit number and inspection schedule in writing. Materials are stored securely; we do not begin demolition until everything critical is on hand.
4. 4
   Demolition, rough work, and documented inspections. The crew arrives in uniform, introduces themselves, and begins demolition with dust containment and haul-away scheduling. We photograph each layer: the subfloor after old flooring removal, the plumbing pressure test, the membrane flood test. These images populate your project folder in real time. Rough inspections pass before any finish work begins.
5. 5
   Finish installation, final inspection, and project closeout. Tile is installed to the approved layout drawing, fixtures set and tested, exhaust fans balanced for airflow. The final inspection secures the certificate of completion. We walk the space with you using a punch list we both sign, deliver the 365-Day Done Right Promise in writing, and transfer all warranty documentation and your complete photo record. If it is not done right, Rowan makes it right, backed by The Haven Standard, not a handshake.
