San Francisco Bathroom Remodel Cost 2026

By Yoni Asulin, ASL Remodeling | CSLB #1060310 | Updated 2026

A standard or guest bathroom remodel in San Francisco starts at a $25,000 construction scope, and finished materials of $6,000 to $25,000 go on top, so it runs $31,000 to $50,000 all in, while a master bathroom runs $55,000 to $95,000 all in. This guide shows where the money goes, what moves the price and which City permit path applies.

What a Bathroom Remodel Costs in San Francisco in 2026

ASL quotes a bathroom in two parts. The first part is the construction scope. It covers labor, rough materials, design and project management. The second part is the finished materials you choose, such as the vanity, the tile and the fixtures. Finished materials are always added on top of the scope. They are never inside it.

For a standard or guest bath, the scope starts at $25,000. Finished materials run roughly $6,000 to $25,000. Together they land at $31,000 to $50,000 all in.

A master bath is a larger tier. The scope runs $40,000 to $50,000 and up. Finished materials for a master bath run roughly $14,000 to $40,000. All in, a master bath runs $55,000 to $95,000.

These are ASL's own ranges for the Bay Area. This guide adds no San Francisco figure of its own, so your price comes from your plan and your selections. When two quotes differ, check which side of the split is different. One quote may leave finished materials out, and that makes it look lower than it is.

Where the Money Goes in a San Francisco Bathroom

The scope pays for the work behind the walls. The finished materials are the parts you see and touch. Here is how the finished materials break down for a standard or guest bath.

Vanity. A vanity runs $800 to $8,000. The low end is a prefab unit with its sink and top included. The high end is a custom cabinet.

Vanity top. A custom vanity needs a separate top, which runs $1,200 to $2,500. A prefab vanity already includes its top.

Shower system and fixtures. A good brand runs $1,000 to $2,500.

Tile. Tile runs $3,000 to $8,000.

Toilet, mirror, lighting and accessories. These run $1,000 to $3,600 together.

Each line is a range, so the lines do not add up to a single number. Your choices decide where in each range you land.

A master bath has its own lines. A double vanity runs $4,000 to $10,000 and up. A freestanding tub runs $800 to $6,000. The vanity top runs $1,500 to $3,000. The shower system, often larger or dual, runs $1,500 to $3,000. Tile for the larger master area runs $5,000 to $15,000. The toilet, mirror, lighting and accessories run $1,500 to $4,500.

These lines cover one room. If you are budgeting a whole house and not a single bathroom, read our San Francisco home renovation cost guide for the larger picture.

What Moves the Price in an Older San Francisco Bathroom

An older bathroom can hide surprises behind the tile. A few choices also move the price no matter how old the room is. Each one depends on your bathroom and your plan.

Guest bath or master bath. This is the biggest step. A master bath has a larger scope and a longer list of finished materials, which is why its all in range starts at $55,000.

Tile area. More wall and floor tile means more material and more labor. A shower tiled to the ceiling uses more than one tiled halfway up. Tile runs $3,000 to $8,000 for a guest bath and $5,000 to $15,000 for a master bath.

Prefab or custom vanity. A prefab vanity keeps the finished materials near the low end. A custom cabinet with a separate top pushes them up.

Tub or walk-in shower. A freestanding tub in a master bath runs $800 to $6,000. A walk-in shower brings its own tile, waterproofing and glass.

Glass. Glass is a separate choice. The price sheet lists no figure for it, so ask for it to be quoted with the rest of the job.

Moving the drain or the walls. A fixture in a new spot means new plumbing. Moving or removing a wall adds work, and it also changes the permit path described below.

What the walls hide. Old plumbing, old wiring and old framing show up once the demolition starts. A contingency of 10 to 15 percent of your budget keeps the job moving when that happens.

This guide gives no separate price for a small bathroom or for a tub to shower swap. Both sit inside the scope of the bathroom, so the price comes from your plan and not from a flat figure.

A Real Peninsula Bathroom Project

The Central Ave primary and guest bathroom remodel is not in San Francisco. It sits in El Granada, which the project page lists under Pacifica. It is worth a look because it shows how a bathroom plan changes once the walls are open.

During demolition, the team found a large HVAC duct buried inside the original tub and wall construction. ASL built custom ductwork with a much flatter profile and routed it into a low pony wall and ledge. No mechanical equipment shows in the finished room.

In the primary bathroom, ASL removed an oversized jetted tub and heavy tiled structures. A freestanding soaking tub, a walk-in shower with frameless glass and custom cabinetry took their place, with new waterproofing throughout.

In the guest bathroom, ASL removed a bulky raised shower structure. The new shower has new tile, updated plumbing fixtures and coordinated lighting, with fresh cabinetry and a new vanity.

The work took 3 months and finished in June 2026. The page lists it at $100,000 and up. That figure covers both bathrooms and the whole project, so do not read it as the price of one bathroom.

San Francisco Permits for a Bathroom Remodel

The City and County of San Francisco sets the permit path by the kind of work. This section follows what the City says on its own pages. Confirm the current rules with the City before you start.

The online permit. The City has an online permit for kitchen and bath remodels. It is for work that is in-kind, with no structural work, and that does not remove or move walls. The City also lists the building types it covers, and the bathroom must be legally permitted.

The over-the-counter permit with plans. Work that needs plans goes through an over-the-counter permit with plans. The City says this includes a remodel that changes the layout or floor plan, a remodel that removes walls and a remodel that legalizes an unpermitted bathroom. That path is applied for in person at the Permit Center.

Electrical and plumbing. These need their own permits in PermitSF. Inspections are requested online in the same portal. The City says the final inspection of the remodel cannot be scheduled until the electrical and plumbing work passes its own final inspections.

ASL handles the permit process for you. The permit fee is the City's charge, not ASL's, and it runs $1,500 to $3,000 for a bathroom. ASL plans for 2 to 4 weeks of approval, although the City sets its own schedule.

A good first step is to describe your plan in the same terms the City uses. Say what stays in place and what moves. That one fact often decides which path applies.

For the wider rules, read our San Francisco remodeling permits guide.

How Long a San Francisco Bathroom Remodel Takes

A bathroom remodel takes about 4 to 6 weeks or more. That time covers demolition, plumbing, waterproofing, tile, fixtures and the final details.

Permit approval runs on its own clock. ASL plans for 2 to 4 weeks, and construction follows the approval.

I cannot promise dates. The City sets its own review schedule, and the walls can hold surprises. What I can tell you is the order. The permit comes first. Then demolition, plumbing, waterproofing and tile follow, and each step has to finish before the next one starts. Fixtures go in last.

If it is your only bathroom, think early about where you will wash during the work.

Choices to Make Before Demolition

Bring photos, measurements and a list of what you want to your first meeting. Settle these choices before demolition, so the plans match what you want. Late changes can mean new drawings, new orders and a slower job.

Layout. Decide where the toilet, vanity and shower go. Keep in mind that moving fixtures or walls changes the permit path.

Tub or shower. Decide between a tub, a walk-in shower or both. In a master bath, decide whether a freestanding tub fits the room.

Tile. Choose the tile and how high it runs on the walls.

Vanity. Decide between a prefab unit and a custom cabinet.

Fixtures. Pick the shower system, the faucets, the toilet, the mirror and the lighting.

Contingency. Set aside 10 to 15 percent of your budget for conditions nobody can see yet.

Lender. ASL does not provide direct financing, but we can point you to reputable home-improvement lenders. Talk to a lender before you sign a scope.

We do not give code advice in a blog post. Those answers come from your plans and from the City's review.

ASL also offers design services to settle the layout and the selections before building begins.
