AfterHow Much Does Tub-to-Shower Conversion Cost in San Francisco?
A tub-to-shower conversion in San Francisco typically costs between $4,130 and $11,800 in 2026, with most mid-range projects landing around $7,500. That price includes demolition of the existing tub, shower pan or base installation, wall substrate and waterproofing, new valve and trim, and a standard glass door or curtain rod setup. High-end conversions with custom tile, frameless glass, and body sprays push toward the top of that range.
San Francisco pricing runs higher than most Bay Area suburbs because of permit requirements, older home construction quirks, and the labor market. Plaster walls, cast-iron drain lines, and 1920s-era floor framing are all common here, and they all add hours to the job. The number above is a real working range we quote from, not a teaser to get you on the phone. That said, the phone is the fastest way to get a written number for your specific bathroom: (831) 610-5598.
If you’re still weighing whether a conversion makes sense versus a full bathroom remodel, start with our Tub-to-Shower Conversion in San Francisco page. It covers the process, timeline, and what a finished conversion looks like in a typical San Francisco bathroom.
Tub-to-Shower Conversion Cost Breakdown (2026)
Here is where the money goes on a typical San Francisco tub-to-shower conversion. These are line-item ranges we see across the city, from the Richmond District down to the Excelsior. Prices assume a standard 60-inch tub footprint, which is what most pre-1980 San Francisco homes have.
| Line Item | Typical Range | Notes |
|---|---|---|
| Demolition & debris removal | $400 – $900 | Cast-iron tubs cost more to cut and haul. Debris pickup in SF often requires a scheduled street permit. |
| Shower base or pan | $350 – $1,200 | Acrylic base on the low end; tile-ready mortar pan with waterproofing on the high end. |
| Wall substrate & waterproofing | $600 – $1,800 | Includes backer board or foam board, membrane, and seam sealing. Non-negotiable if you want the job to hold. |
| Valve, trim & showerhead | $300 – $1,500 | Basic pressure-balance valve up to a thermostatic system with multiple outlets. We install Kohler and Moen. |
| Wall tile & labor | $900 – $3,000 | Basic subway tile at the low end; large-format porcelain or natural stone at the top. Labor is the biggest variable. |
| Glass door or rod | $200 – $2,500 | Shower rod and curtain on the low end; custom frameless glass door on the high end. |
| Permits & inspections | $250 – $700 | San Francisco requires a plumbing permit for changing the tub drain to a shower drain. Some jobs also need an electrical sign-off. |
| Accessories (niche, bench, grab bars) | $100 – $600 | Pre-fab niche is cheap; a tiled bench adds real labor. |
What moves the number up or down? The biggest drivers are tile scope, glass, and what’s hiding behind the walls. A 1920s Sunset District bathroom with rock-lath plaster and galvanized drain lines will run toward the high end. A relatively modern bathroom, say 1990s construction in Mission Bay, will sit lower because the substrate is sound and the drain line is ABS plastic that ties straight into the new shower base.
One thing to be clear on: the price you get in writing before we start is the price you pay. That’s The Garrison Standard, and it applies to every Bradford remodeling project in San Francisco. No door knock re-pricing, no “we found something” surprise invoices. If we discover an unknown during demo, we document it, show you, and agree on any change in writing before proceeding.
What Affects Tub-to-Shower Conversion Pricing in San Francisco
- Building age and construction type. Pre-1940 San Francisco homes have plaster walls, full-dimension lumber, and sometimes asbestos-containing materials in old tile adhesive. Plaster removal is slower than drywall demolition, and asbestos abatement triggers a separate licensed contractor, which adds $500 to $2,000 to the job.
- Drain line condition. Many older SF bathrooms still have cast-iron or galvanized drain lines. A tub drain is 1.5 inches; a shower drain needs to be 2 inches by code. If the line needs to be cut and adapted, that adds labor. If it’s rotten, that’s a bigger conversation with a bigger number.
- Wall tile scope and size. Standard 3×6 subway tile is fast to install. Large-format 24×48 porcelain panels require more precise layout, heavier handling, and a leveling system. Expect to pay 40 to 60 percent more in tile labor for large-format work.
- Glass configuration. A shower rod and curtain costs almost nothing. A sliding bypass door is mid-range. A custom frameless glass panel with a hinged door is the most expensive option, typically $1,500 to $2,500 in the San Francisco market, and it requires precise wall fitting, which means the framing has to be dead plumb.
- Waterproofing method. A basic acrylic wall surround with a fiberglass pan is the cheapest waterproofing path. A full waterproof membrane system, like a sheet membrane or liquid-applied membrane over cement board, costs more but creates a substrate that holds up to daily moisture in a fog-belt climate. San Francisco bathrooms run humid, and a shower used twice daily needs a real waterproofing assembly, not a bead of caulk.
- Permit status and access. Even a straightforward conversion needs a plumbing permit in San Francisco. If your building is older and the bathroom has never been permitted, the inspector may flag other items he can see. If you live in a condo, your HOA may also require notification or approval, and elevator buildings add time for material movement. All of that affects schedule, and schedule affects price.
How to Save on Tub-to-Shower Conversion
Saving money on this job is mostly about scope discipline, not cutting corners. Here is where homeowners actually save, based on conversions we have done throughout San Francisco neighborhoods.
- Keep the footprint. Moving the drain or shifting a wall is where costs balloon. A straight tub-to-shower swap in the same footprint avoids structural work, and that is where the real savings are.
- Choose a pre-fab shower base over a tiled pan. A solid-surface or acrylic base installs in a few hours and is easy to maintain. A tiled pan requires extra waterproofing layers, a longer cure time, and more tile labor. You can save $800 to $1,500 just on the base.
- Skip the custom glass if the budget is tight. Start with a rod and curtain, then add frameless glass later. The glass company still measures the finished opening, so it works either way. This can save $1,500 to $2,500 on the initial project.
- Do the demo yourself. If you are comfortable with a reciprocating saw and can safely cap or disconnect the water supply, you can remove the old tub and tile before we arrive. That saves $400 to $900 in our labor, but check with your building manager or HOA first, and never cut into a wall without confirming what’s behind it.
- Use standard tile sizes. Subway tile, 12×24 porcelain, or 4×4 ceramic are standard stock sizes. Custom or specialty tile costs more to buy and more to install. If you want a distinctive look, use a decorative accent strip instead of tiling the whole shower in something unusual.
The biggest fake savings in this trade is waterproofing. A shower that leaks through the pan or wicks moisture into the framing is a $15,000 to $30,000 repair a few years later, not a $1,500 fix. We do not offer “cheap” waterproofing because it doesn’t exist. What we do offer is a written scope, a written price, and a written one-year guarantee that the work holds. Call (831) 610-5598 and we will walk you through where your budget should go, line by line.
Is a Tub-to-Shower Conversion Worth It in San Francisco?
For most San Francisco homeowners, the answer is yes. It is the single highest-impact bathroom change you can make for the money. A conversion opens up floor space in a bathroom that is often less than 50 square feet, it improves daily function for anyone with mobility issues, and it makes the room feel larger because the visual mass of the tub is gone. In the San Francisco resale market, a clean, functional shower is a stronger selling point than a rarely-used tub in guest bathrooms and hall baths.
One nuance: if your home has only one full bathroom and you have young children, keep the tub. The conversion makes daily life harder, not easier, if you need a tub for bathing kids. If you have a second tub elsewhere in the house, converting the primary bathroom tub to a shower is one of the better return-on-investment projects you can do, especially in the $600,000 to $1.2 million condominium range common in the Sunset, Richmond, and Glen Park.

FAQs – Tub-to-Shower Conversion Cost
How much does a tub-to-shower conversion cost in San Francisco in 2026?
Expect to pay $4,130 to $11,800 for a conversion in San Francisco, with most jobs finishing between $6,500 and $9,000. The final number depends on tile, glass, and what is behind your existing walls. Call (831) 610-5598 for a written number on your specific bathroom.
Is it cheaper to convert a tub to a shower than to remodel the whole bathroom?
Yes. A full small bathroom remodel in San Francisco runs $5,900 to $14,160, and a standard bathroom remodel is $10,620 to $33,040. A tub-to-shower conversion at $4,130 to $11,800 is the more contained job because you are working inside the existing footprint and not touching the vanity, toilet, or floor.
How long does a tub-to-shower conversion take?
A straight conversion in San Francisco takes 3 to 5 working days on site. That includes demo, plumbing adaptation, waterproofing, tile, and glass installation. Custom tile patterns or large-format work can push it to 6 or 7 days. The permit and inspection process in San Francisco adds a few days on the calendar, though not on your job site.
Do I need a permit for a tub-to-shower conversion in San Francisco?
Yes. San Francisco requires a plumbing permit when you change the drain configuration from a tub to a shower. The city’s plumbing code also requires a 2-inch drain line for a shower where a tub only needs 1.5 inches. We pull the permit, schedule the inspection, and the permit is included in our written price.
Can you replace my tub with a walk-in shower for accessibility?
Yes. A curbless or low-threshold shower with a built-in bench and grab bar reinforcement runs toward the top of the conversion range, typically $8,500 to $11,800 in San Francisco. We frame in blocking for grab bars behind the tile so they are anchored to structure, not drywall. If you are planning for aging in place, tell us before we write the price so we can include the blocking and bench in the original scope.
Why San Francisco Homeowners Choose Bradford Remodeling
Bradford Remodeling Co San Francisco is part of the Garrison Partners family, established in 2004 and operated under The Garrison Standard. The Garrison Standard is simple: a written price before any work starts, a documented scope of work, and a signed guarantee in your hand when the job is done. The Garrison Code governs conduct on the job site: background-checked, uniformed technicians, a clean site at the end of every day, and a live person answering our phone 24 hours a day, seven days a week.
Our 365-Day Done Right Promise means that every finished project carries a full-year written guarantee. If the work fails inside that window, we come back and correct it at no charge. That applies to the waterproofing, the tile, the valve, the trim, the glass hardware, and every other part of the conversion we touch. If it is not right, we make it right. That is the promise, in writing, every time.
We install documented, name-brand materials on every job: Kohler and Moen fixtures, Schluter waterproofing systems, James Hardie backer board, and Delta or Grohe trim packages depending on your spec. These are products with manufacturer warranties and published specs, not whatever the supply house had on the shelf. That matters because a conversion is only as good as the assembly behind the tile.
Curtis Lane leads Bradford Remodeling Co San Francisco. He has built the local operation around one principle: give the homeowner a real number, put it in writing, and do exactly what the paper says. If you are tired of contractors who no-show, reprice at the door, or leave the job half done, you will find Bradford operates differently. The home page explains the full service area and the range of remodeling work we handle in San Francisco.
When the job is complete, here is what “squared away” looks like: the site is swept and the debris is hauled, the shower has been tested for leaks, the glass is clean, and you are holding a signed written guarantee that covers the work for 365 days. No punch-list limbo, no chasing a subcontractor who disappeared.
If your tub has worn out its welcome and you want a shower that actually works for how you live, call (831) 610-5598. We will give you a written price, in writing, before a single tool comes out. That is the only way we work.
