AfterHow Much Does Tub-to-Shower Conversion Cost in San Diego?
A tub-to-shower conversion in San Diego typically costs $4,130 to $11,800 for a standard 60-inch alcove replacement, with most homeowners landing between $6,000 and $9,000. The final number depends on whether you’re keeping the existing drain location, what waterproofing method is used, and whether the existing plumbing needs rerouting. At Penhallow Remodeling San Diego, we give you a written price before any work starts, so the number you agree to is the number you pay.

Tub-to-Shower Conversion Cost Breakdown (2026)
Here’s what actually makes up the cost of a tub-to-shower conversion in San Diego. These are real market ranges we see on jobs across neighborhoods from Clairemont to Chula Vista.
| Line Item | Typical San Diego Range |
|---|---|
| Demolition & disposal of existing tub | $450 – $950 |
| Plumbing modifications (valve relocation, drain adjustment) | $600 – $1,800 |
| Waterproofing system (cement board substrate + membrane) | $500 – $1,200 |
| Shower pan installation | $700 – $1,800 |
| Wall tile (materials + labor, standard 60″ surround) | $1,200 – $3,200 |
| Glass shower door (framed to semi-frameless) | $800 – $2,200 |
| Fixtures (valve, showerhead, trim kit) | $250 – $900 |
| Frameless glass panel (optional upgrade) | $1,500 – $3,500 |
| Permit & inspection fees | $200 – $600 |
At the low end, a straightforward conversion with a prefabricated shower pan, basic tile, and a curtain rod instead of glass can run under $5,000. At the high end, a custom tile shower with a frameless glass enclosure, relocated plumbing, and a bench or niche can push past $11,000. The $4,130 to $11,800 range covers what we see across the San Diego market in 2026, from National City to Poway.
The biggest swing factors are the glass enclosure and whether the drain needs to move. Moving a drain from tub position (centered) to shower position (offset toward the wall) means cutting into the slab or opening the floor below. That alone can add $500 to $1,200 depending on what’s under the bathroom.
What Affects Tub-to-Shower Conversion Pricing in San Diego
- Slab vs. raised foundation: Most San Diego homes built after 1960 sit on concrete slabs, which means relocating a drain requires cutting concrete. In coastal neighborhoods like Ocean Beach or Pacific Beach, you’re also dealing with sandier soil and occasional dampness under the slab, which can affect waterproofing decisions.
- Waterproofing method: A cement board substrate (the moisture-resistant layer behind your tile) with a roll-on membrane costs less than a full foam-board system, but the foam boards install faster and give you a flatter surface. We’ll quote whichever fits the job, not whichever pads the invoice.
- Tile choice: Standard 4×4 ceramic tile runs $3 to $8 per square foot for material. Large-format porcelain or natural stone runs $10 to $30 per square foot, and labor goes up because the pieces are heavier and trickier to set on a shower wall.
- Glass enclosure style: A framed sliding door is the most affordable. Semi-frameless runs about $1,200 to $1,800. Fully frameless glass with a swing door and panel is the cleanest look and the most expensive, usually $2,500 to $3,500 installed.
- Accessibility features: A low-threshold or curbless entry, grab bars, and a built-in bench add $400 to $1,500 total. If you’re planning to age in place, this is the time to add them, not after the tile is set.
- Permit timeline: San Diego requires a plumbing permit for any tub-to-shower conversion that changes the drain or valve. The permit itself is modest, but the inspection scheduling can extend a project by a few days depending on the inspector’s queue.

How to Save on Tub-to-Shower Conversion
You don’t have to cut corners to keep a tub-to-shower conversion affordable. Here’s how San Diego homeowners keep costs down without ending up with a shower that leaks into the hallway after the first winter rain settles in.
- Keep the drain where it is. If you’re fine with the shower drain roughly centered under the showerhead, you skip the slab-cutting and the $500 to $1,200 plumbing reroute that comes with it.
- Choose a prefabricated shower pan over a custom mortar bed. Modern acrylic and composite pans look clean, don’t require tile-setting skill on the floor, and cost $400 to $900 less than a custom tiled base.
- Skip the bench and niche on a tight budget. Both are nice to have, but a niche adds $300 to $600 and a bench adds $400 to $800. A corner shelf from the same tile line costs under $50.
- Do the demo yourself. If you’re comfortable removing the old tub, tile, and drywall, and hauling it to the Miramar Landfill, you can save $450 to $950. Be careful though: old tubs are heavy, and cast iron tubs can weigh 300 pounds or more. Two people and a shoulder dolly are mandatory.
- Ask about fixture packages. Plumbing showrooms in San Diego run seasonal promotions on valve-and-trim kits. We’re happy to install fixtures you purchase, as long as they’re new in box and meet current California water-efficiency codes.

Is a Tub-to-Shower Conversion Worth It?
This is the question every homeowner in San Diego asks before taking a sledgehammer to a perfectly functional tub. The honest answer: it depends on who will be using the bathroom and how long you plan to stay in the house.
If someone in the household has mobility concerns, a tub wall is a daily obstacle. The low-threshold shower entry removes that. If you’re selling within two to three years, a tub-to-shower conversion can actually hurt resale value in some San Diego neighborhoods where young families dominate, because parents of small kids often want at least one bathtub in the home. If you plan to stay five years or more, the conversion is a quality-of-life upgrade that pays off every morning.
We always tell people to keep a tub somewhere in the house if there are multiple bathrooms. Converting the master bath while keeping the hall bath tub is the most common, and smartest, approach we see in San Diego.
How Long Does a Tub-to-Shower Conversion Take?
Most tub-to-shower conversions in San Diego take 5 to 9 working days from demo to final inspection. A straightforward swap with a prefabricated pan and standard tile can finish in 4 days. A full custom job with a mud-set pan, large-format tile, and frameless glass takes 8 to 10 days because each phase, waterproofing, tile setting, grout curing, has to dry or cure before the next one starts.
Peak season in San Diego runs from March through October. If you’re calling in June, expect a two-to-four-week lead time before we can start. January and February are typically the fastest months to book.
Can You Fix My Shower the Same Day?
For a full tub-to-shower conversion, no. That’s a 5-to-9-day project with inspections. But if you have a leaking shower valve or a failed drain seal and need it done immediately, we can often dispatch a technician to assess it, and in many cases complete the repair, the same day. Whether it’s a repair or a full conversion, we’ll give you the number before we pick up a tool.

Tub-to-Shower Conversion vs. Shower Replacement: What’s the Difference?
A tub-to-shower conversion means removing an existing bathtub and building a shower in the same footprint. A shower replacement means tearing out an existing shower and installing a new one in the same spot.
Shower replacements in San Diego run $3,540 to $10,030, slightly lower than conversions because the drain is already in the right place and there’s no tub to haul out. If you already have a shower and it’s just tired, replacing the pan, valve, and tile is the more affordable path. If you have a tub that’s gathering dust, the conversion makes sense.
How Much Does a Walk-In Shower Cost in San Diego Without a Tub Conversion?
A walk-in shower installation from scratch runs $5,310 to $14,160 in San Diego. That’s for a new shower built in a space that wasn’t previously a shower or tub, which means all-new plumbing, drainage, waterproofing, and usually a glass enclosure. A tub-to-shower conversion is usually cheaper because the plumbing is already in the wall and the floor already has a drain line, even if it’s in the wrong spot.
FAQs – Tub-to-Shower Conversion Cost
How much does a tub-to-shower conversion cost in San Diego?
A tub-to-shower conversion in San Diego costs $4,130 to $11,800 in 2026, with most jobs finishing between $6,000 and $9,000. The range covers everything from a basic prefab pan with standard tile to a custom tile shower with frameless glass. Call (619) 604-9624 for a free, no-pressure written estimate for your specific bathroom.
Is it cheaper to repair or replace and convert a tub?
If you’re asking about a tub with a cracked surface, a peeling finish, or a warped floor, the answer is almost always to convert. Reglazing a tub in San Diego runs $450 to $850 and lasts three to five years before it starts peeling again. A conversion starts at $4,130 and gives you a shower that lasts 20 to 30 years. If the tub is still solid but you want the shower accessibility, conversion is the better long-term number.
Can you convert my tub to a shower in one day?
No, and any contractor who tells you otherwise is cutting a corner that will show up as a leak within the year. Proper waterproofing requires drying time between coats, tile needs grout cure time, and San Diego plumbing inspections add a day. Budget 5 to 9 working days. What we can do in one day is assess your bathroom, confirm the drain situation, and hand you a written quote. Call (619) 604-9624 to schedule that visit.
How much does it cost to replace a tub with a walk-in shower?
Replacing a tub with a curbless or low-threshold walk-in shower in San Diego runs $5,310 to $14,160. The added cost over a standard conversion comes from the structural work needed to lower or recess the shower floor while maintaining proper slope to the drain. On slab foundations, which are common across San Diego, this means cutting concrete and sometimes adjusting the subfloor framing for proper drainage pitch.
What’s the most expensive part of a tub-to-shower conversion?
The glass enclosure. A framed door runs $800 to $1,200, but a fully frameless glass panel and door set runs $2,500 to $3,500 installed. That single choice can add $2,000 to the final invoice. If budget is tight but you still want the open look, semi-frameless glass splits the difference at $1,200 to $1,800.
Does converting a tub to a shower add value in San Diego?
For the right buyer, yes. An updated bathroom with a walk-in shower returns roughly 60% to 70% of its cost at resale in San Diego, according to national remodeling cost-vs-value data adjusted for our market. More importantly, it makes the home easier to live in today. Our 365-Day Done Right Promise means if the work fails inside the guarantee period, we come back and fix it at no charge, covered in writing on every project.
