Bathroom remodeling

What a Bathroom Remodel Involves, Behind the Tile

A bathroom remodel can be as small as replacing a vanity, toilet and faucets, or as large as taking the room to the studs for a new shower, tub, tile and lighting. The bigger the change, the more of the work happens where you will never see it: drains, supply lines, wiring, ventilation and waterproofing.

Waterproofing is what decides whether a shower lasts. Tile and grout are not waterproof on their own; the membrane behind them keeps water out of the framing. That layer, the slope of the shower floor and a properly set drain matter more to a bathroom renovation than the tile chosen for the surface.

We remodel bathrooms in homes from San Francisco and Oakland to San Jose and Walnut Creek, often together with a kitchen remodel or with interior painting for the hallway and bedrooms around it.

What lasts

Why Waterproofing Matters More Than the Tile You Pick

Most bathroom failures start with water getting behind the surface. These are the details that keep it out, and the shortcuts that let it in.

What goes behind our tile

  • Damaged framing and subfloor repaired first
  • A waterproofing membrane on shower walls and floor
  • A shower floor sloped to the drain
  • Sealed niches, benches and corners
  • An exhaust fan that vents outside

Shortcuts that cause leaks

  • Tile set on drywall in a wet area
  • Relying on grout or caulk to stop water
  • A flat shower floor that holds puddles
  • Skipping the membrane at niches and seats

Older home? A bathroom permit there may also require water-saving fixtures; see the rules below.

Permits and rules

Do You Need a Permit to Remodel a Bathroom?

Tile and paint alone are exempt finish work in Oakland and Berkeley, and Berkeley lets you remove and reinstall a toilet without a permit. Replacing a concealed drain, moving fixtures or new wiring needs a permit, and in homes built on or before 1994 that permit requires water-saving fixtures.

  • Berkeley exempts tiling and similar finish work and removing and reinstalling a toilet, but requires a permit to replace a concealed trap, drain, waste or vent pipe, per its work exempt from building permits page.
  • Oakland lists tiling, cabinets and countertops as exempt finish work, but notes that planning or zoning permits may still apply, per its exempt work page.
  • Under Civil Code 1101.4, a permit for an alteration in a single-family home built on or before January 1, 1994 requires replacing noncompliant toilets, showerheads and faucets before final approval, as Berkeley's SB 407 guideline explains.
  • Oakland treats a duplex as single-family for this rule: altering one unit triggers fixture upgrades in that unit only, per its SB 407 handout.

Paint disturbed in a pre-1978 Oakland home needs a lead-based paint permit, even inside a bathroom.

Bathroom remodel answers

Bathroom Remodel Cost, Value and Permit Questions

Before calling a bathroom remodeling contractor, homeowners want to know what a small budget covers, what adds value, whether they need a permit and what older homes require. These answers come from our bathroom work and from Bay Area city rules.

Can I remodel my bathroom for $5,000?

A budget that size usually fits a cosmetic refresh: a new vanity, toilet, faucets, mirror, lighting and paint, with the shower, tub and plumbing left in place. Once tile comes off or a fixture moves, demolition, waterproofing and permits enter the job and the total changes quickly. An itemized estimate shows exactly where the line falls.

We can price a refresh and a full remodel side by side.

What adds the most value to a bathroom?

Buyers and daily users notice a clean, watertight shower, good ventilation, enough storage and lighting that works at the mirror. A dated layout that functions well can often be refreshed rather than rebuilt. Spending on hidden quality, like waterproofing and a vented fan, protects the value of everything on the surface.

Keeping the toilet and shower drain where they are saves the most.

Do I need a permit to remodel a bathroom?

For tile and paint alone, usually not; Oakland and Berkeley list them as exempt finish work. Replacing a concealed drain, moving a toilet or shower, or adding wiring needs a permit. In a home built on or before 1994, that permit also requires water-conserving toilets, showerheads and faucets.

The permits your city requires are listed in the estimate.

What is the most expensive part of a bathroom remodel?

Usually the shower: tearing out old tile, waterproofing, new tile, the valve and a glass enclosure add up to the largest share of the job. Moving the toilet, shower drain or vanity plumbing is the next big cost, because floors and walls must open. A new vanity and fixtures in place cost far less.

Keeping the shower drain where it is protects the budget most.

Does a bathroom remodel require low-flow fixtures?

In California homes built on or before January 1, 1994, yes, when the remodel needs a permit. Civil Code 1101.4 requires noncompliant fixtures to be replaced with water-conserving ones before the permit is finaled. Fixtures that already meet the water-use limits do not have to be changed.

We fit compliant fixtures as part of the remodel, so the final inspection is not held up.

FAQ

Bathroom Remodeling FAQ

Ready for a New Bathroom?

Send photos of the bathroom, its rough size and what you want to change, and we will reply with a written estimate. Reach us Monday to Saturday, 9 am to 5 pm, or browse the FAQ page in the meantime.

Call (650) 404-7049
How long does a bathroom remodel take?

A fixture and vanity refresh is a short job; a full remodel down to the studs takes longer because waterproofing, tile and inspections each need their own time. Custom glass is ordered after the tile is set, which adds lead time. Your estimate includes the expected schedule.

Can you turn a tub into a walk-in shower?

Tell us about it when you request an estimate. Whether it works depends on the drain location, the floor framing and the space for a glass enclosure, so we look at the bathroom before confirming. If the drain has to move, that plumbing work goes in under permit.

What kind of tile do you install?

We install the tile you choose, from porcelain and ceramic to marble-look and natural stone, on walls and floors. The tile is the finish; what keeps the shower dry is the waterproofing membrane underneath it and the slope of the floor to the drain.

Do you replace the vanity and toilet too?

Yes. Vanities, tops, sinks, faucets, toilets and mirrors are part of most bathroom remodels. If the new vanity is a different size, the supply and drain lines are adjusted, and in older homes the new fixtures are chosen to meet the state water-use limits.

What happens if you find water damage?

We stop and show you before going further. Rotted framing or a damaged subfloor has to be repaired before waterproofing, and we price that repair in a signed change order. Fixing it during the remodel is far cheaper than after new tile is on.

How do I get a bathroom remodel estimate?
