Oakland’s housing stock runs the gamut: Craftsman bungalows in Rockridge, mid-century ranches in the Oakland Hills, Victorian flats in West Oakland, and newer builds in Jack London Square. Each era brings different plumbing configurations, subfloor conditions, and permit requirements through Oakland’s Building Services Division. We’ve worked in all of them. The 365-Day Done Right Promise, backed by The Haven Standard, means if it is not done right, Rowan makes it right - the guarantee is printed on every page and backed by a terms page, not an asterisk.

Our crews are background-checked and uniformed; every visit includes a documented photo record as standard, not an upgrade. Under Clause 1 of the Haven Standard, the price is written before anyone starts. No change proceeds without a signed change order, which is the discipline that has kept our projects within a few percent of the agreed cost across 4,000-plus jobs.

What Our Bathroom Remodeling Service Includes

Full Bathroom Remodeling

Bathroom Remodeling - Berkeley neighbors know a full bathroom remodel strips the room to the studs and rebuilds it: new layout, new plumbing rough-in, new electrical, new finishes. Oakland homeowners typically pursue this when the bathroom has reached functional obsolescence - galvanized supply lines, ungrounded outlets, or a layout that wastes square footage in a city where every foot matters. We handle permit pulling through Oakland Building Services, coordinate inspections, and deliver a flat written price before demolition begins. The quote specifies every material brand, from the membrane behind the tile to the escutcheon on the valve.

Walk-In Showers & Shower Remodeling

Walk-in shower remodeling replaces a tub-shower combo or existing shower with a curbless or low-threshold enclosure, often with frameless glass. In Oakland’s older homes, this frequently requires reinforcing the subfloor to support a mortar bed and updating the drain to a linear or center drain depending on the design. We specify the waterproofing membrane system - liquid-applied or sheet membrane - in the written quote, and we document the flood test with photos before tile goes up. Our sourcing depth across fifty-plus vetted brands gives the written quote honest numbers rather than inflated ones.

Tub-to-Shower Conversion

A tub-to-shower conversion removes the existing bathtub and installs a shower base or custom-tiled shower in its footprint. This is the most common bathroom project we see in Oakland’s 1950s-1970s ranches, where families want to age in place or simply prefer a shower. The critical detail is the drain location: if the tub drain is centered and the new shower base requires an offset, we specify the plumbing modification in the written scope, with a signed change order if exploratory work reveals cast-iron fittings that need replacement. No work proceeds on a change until the change order is signed.

Vanities

Vanity installation ranges from a straightforward swap of a stock cabinet to a custom built-in with stone countertop, undermount sink, and wall-mounted faucet. In Oakland’s smaller bathrooms, particularly in the flats near Lake Merritt, we often recommend floating vanities to visually expand floor space - a technique we also apply in Bathroom Remodeling - Alameda projects. We source KraftMaid and Wellborn cabinets among our vetted brands, and we specify the countertop material - Cambria or Caesarstone for quartz, or a natural stone with documented sealing requirements - in the written quote. The price includes rough plumbing modification if the new vanity’s drain location differs from the old.

Tile & Fixtures

Tile and fixture installation covers the visible finish layer: floor tile, wall tile, shower enclosure tile, and the faucets, shower valves, toilets, and lighting that complete the room. In Oakland, we see a lot of porcelain plank tile on floors (durable, water-resistant, compatible with in-floor heat if specified) and ceramic or porcelain subway tile on walls. We specify grout type, sealant schedule, and expansion joint placement in the written scope. Fixtures are sourced from Kohler and Toto among our vetted brands, with model numbers listed so you can verify specifications independently.

Small Bathroom Remodels

Small bathroom remodeling - typically 5′ x 8′ or less - demands precise space planning and often requires compact fixtures designed for tight clearances. In Oakland’s older housing stock, these bathrooms frequently have plaster walls, lead supply lines, or inadequate ventilation that must be addressed before cosmetic work begins. We deliver written pricing for small bathroom remodels starting at $5,000, with the scope clearly distinguishing between required code upgrades and optional upgrades. The documented photo record shows substrate condition, framing modifications, and finished work - evidence you can reference if you sell the property.

Walk-In Shower Installation

Walk-in shower installation in new construction or additions follows a different sequence than remodels, with the plumbing rough-in occurring before wall framing is complete. For Oakland homeowners adding an ADU or home addition, we coordinate the shower specification with the overall plumbing plan, specifying the valve rough-in height, drain type, and waterproofing system in the construction documents. Our home addition and ADU work uses the same written-price discipline: a flat price with a written scope and a written warranty before any work starts.

Brands We Service for Bathroom Remodeling

We’ve installed and serviced Kohler fixtures across hundreds of Oakland bathrooms, from the classic Devonshire line in Rockridge renovations to the Purist collection in modern builds near Jack London Square. Our crews know the valve cartridge interchangeability, the trim compatibility across generations, and the warranty registration process - we document the model and serial numbers in your project file so you have them for future service.

Toto is our go-to for homeowners who want water efficiency without performance compromise; we’ve installed the Drake II and Ultramax II in bathrooms throughout the Oakland Hills, where water pressure can vary by elevation. We also work with Cambria and Caesarstone for countertops, specifying the slab or template dimensions in the written quote so there’s no ambiguity about material cost. Whether you have Kohler, Toto, Cambria, or any other make, we can help - and we’ll name the price in writing before anyone picks up a tool.

Signs You Need Bathroom Remodeling Right Now

• Water damage on the ceiling below the bathroom. This indicates a leak in the supply line, drain, or shower pan that has progressed past the point of caulk-and-pray repair. In Oakland’s older homes with original plaster lath ceilings, the damage spreads quickly and the repair requires opening the ceiling to inspect the subfloor above. We document the extent with photos and specify the remediation scope in the written quote.
• Soft or spongy floor tiles near the toilet or tub. A subfloor compromised by chronic moisture loses structural integrity; walking on it accelerates the damage and risks cracking the tile or, worse, falling through. In Oakland’s flat-roofed mid-century homes, bathroom ventilation is often inadequate, compounding the problem. We specify subfloor replacement, ventilation upgrade, and moisture barrier installation as separate line items so you see where the money goes.
• Visible mold on grout, caulk, or drywall. Surface mold is often a symptom of failed waterproofing behind the tile - the membrane has degraded or was never properly installed. In Oakland’s fog-adjacent climate, bathrooms without adequate exhaust fans stay humid longer, accelerating mold growth. We specify the remediation: remove affected materials, treat framing with antimicrobial, install proper waterproofing, and upgrade ventilation - each step priced separately.
• Galvanized steel supply lines. These pipes, common in Oakland homes built before 1960, corrode from the inside, reducing water pressure and eventually leaking. If your bathroom has galvanized supplies, a cosmetic remodel without pipe replacement is money wasted - the pipes will fail behind your new tile. We specify copper or PEX replacement in the written scope, with permit and inspection included.
• The layout does not work for your household. A single vanity for a family of four, a tub-shower combo when you need a walk-in, a toilet that blocks the door swing - these are design failures that diminish daily life and resale value. In Oakland’s competitive housing market, a well-designed bathroom returns proportionally more value than a poorly designed one. We measure, draw, and price the reconfiguration before demolition, so you know the cost of the solution.

Our Bathroom Remodeling Process - Step by Step

1. 1
   In-home assessment and measurement. We arrive with a laser measure, moisture meter, and inspection camera. We document the existing conditions - substrate type, plumbing material, electrical panel capacity, ventilation - and photograph everything. You receive this photo record as standard, not an upgrade. We explain what we found, not what we felt about it: the subfloor is 3/4″ plywood with 12% moisture content, the supply lines are copper with brass fittings, the exhaust fan moves 50 CFM in an 80-square-foot room. Then we explain what it means: the subfloor is sound, the plumbing is serviceable, the fan is undersized by code.
2. 2
   Written quote with flat price and line-item scope. Within 48 hours, you receive a written quote specifying every material brand and model number, every labor line item, and the project timeline. The price is flat - not an estimate that balloons - and it includes permit fees, inspection scheduling, and the documented photo record. Under Clause 1 of the Haven Standard, this written price is delivered before any work starts, every time. Free Second Opinion on any written estimate: bring a competitor’s quote and Rowan will review it line by line at no charge.
3. 3
   Permit application and material procurement. We pull permits through Oakland Building Services and schedule inspections at rough-in and final. Materials are ordered with confirmed lead times; we track delivery and store on-site or off-site as conditions require. If a material becomes unavailable - supply chain disruptions still occur - we present alternatives with equivalent specifications and pricing before substituting. No change proceeds without a signed change order.
4. 4
   Demolition, rough-in, and inspection. Demolition is contained with plastic sheeting and HEPA filtration where required. Plumbing and electrical rough-in follows, with pressure testing on supply lines and GFCI verification on circuits. We photograph the rough-in before wall closure: pipe routing, valve placement, blocking for grab bars if specified. The inspector signs off; we document the approval tag.
5. 5
   Finish installation, final inspection, and project closeout. Tile, fixtures, paint, and hardware are installed to the specification in the written scope. We conduct a walkthrough with you, demonstrating valve operation, cleaning procedures, and warranty registration. The final photo record documents the completed work. The 365-Day Done Right Promise begins: if it is not done right, Rowan makes it right - backed by The Haven Standard, not a handshake.
