AfterHow Much Does a Tub-to-Shower Conversion Cost in San Diego?
A tub-to-shower conversion in San Diego typically costs between $4,130 and $11,800, depending on shower size, tile selection, fixture grade, and whether the plumbing needs to be relocated. Most San Diego homeowners completing a standard alcove conversion with prefabricated walls and basic fixtures land in the $4,500-$6,500 range, while custom tile showers with frameless glass and upgraded Kohler or Toto fixtures push toward the higher end.

Tub-to-Shower Conversion Cost Breakdown (2026)
San Diego tub-to-shower conversion costs break into distinct line items. Knowing what each piece costs separately tells you immediately where a quote is padded and where it’s reasonable.
| Scope of Work | Typical San Diego Cost Range |
|---|---|
| Tub removal and haul-away | $250-$550 |
| Substrate prep (cement board, Schluter Kerdi membrane) | $400-$900 |
| Prefab acrylic or fiberglass surround (installed) | $1,200-$2,800 |
| Tile walls – ceramic or basic porcelain (materials + labor) | $1,800-$4,200 |
| Tile walls – large-format or specialty tile (materials + labor) | $3,200-$6,500 |
| Shower floor pan – prefab acrylic | $350-$700 |
| Shower floor – custom tile with linear drain | $900-$2,200 |
| Basic shower valve and trim (Kohler Forte or comparable) | $300-$650 |
| Upgraded thermostatic valve system | $700-$1,800 |
| Frameless glass door or enclosure | $900-$2,500 |
| Framed or semi-framed glass door | $350-$950 |
| Plumbing relocation (if drain must move) | $600-$2,000 |
| Niche or built-in shelf (tiled) | $300-$700 per niche |
| Permits (City of San Diego) | $200-$500 depending on scope |
| Full conversion – entry level | $4,130-$5,500 |
| Full conversion – mid-range custom tile | $5,500-$8,500 |
| Full conversion – premium custom tile + frameless glass | $8,500-$11,800 |
A few things that move the final number quickly: San Diego’s coastal humidity means we almost always specify a waterproofing membrane – typically Schluter Kerdi or RedGard – rather than relying on cement board alone. That membrane adds $400-$900 to a job but prevents the tile delamination and mold problems we see in older San Diego homes where builders skipped it. If the existing drain sits in the wrong position for a shower pan, relocation adds $600-$2,000 and sometimes requires a permit pull on top of the structural permit. And because San Diego sits in a seismically active zone, larger format tiles (anything over 15″x15″) require a polymer-modified thinset rated for flex – material cost is modest, but any tile setter who doesn’t spec it is cutting a corner that shows up in three to five years.
Grant Rowan and the team at Rowan Construction Group have been quoting these jobs with flat written prices since 2007. The number on the page before work starts is the number on the invoice when the crew leaves – that’s Clause 1 of the Haven Standard, not a marketing line.
What Affects Tub-to-Shower Conversion Pricing in San Diego
- Tile selection and square footage covered. A standard 32″x60″ alcove shower has roughly 80-100 square feet of wall surface. Ceramic tile at $4-$7 per square foot installed keeps you in the entry-level range. Switching to large-format porcelain slabs at $14-$22 per square foot installed – popular in North Park, Mission Hills, and Del Cerro renovations right now – can add $1,500-$3,000 to wall tile cost alone before you touch the floor.
- Plumbing configuration and drain location. If the existing tub drain lines up with a standard shower pan, conversion is straightforward. When it doesn’t – common in older craftsman homes in South Park or Normal Heights – a plumber needs to reroute the P-trap and sometimes cut the slab. That’s an $800-$2,000 addition and adds a day to the schedule.
- Glass enclosure type. A framed sliding door runs $350-$950 installed. A custom frameless glass enclosure with 3/8″ or 1/2″ tempered glass runs $900-$2,500 and requires a precision-measured lead time of 10-14 days for fabrication. Many San Diego homeowners in higher-value zip codes like La Jolla and Point Loma choose frameless because it photographs better and holds resale value, but the cost difference is real.
- Substrate condition discovered after tub removal. In San Diego homes built before 1985, we regularly find green board drywall behind the tub surround instead of cement board – sometimes with active water damage that wasn’t visible until demolition. Replacing a full wall of damaged substrate adds $300-$800 to the job. This is exactly why a no-change-without-a-signed-change-order policy matters: you know the number before the repair starts, not after.
- Fixture and fitting grade. A Kohler Forte pressure-balance valve with a rain showerhead runs roughly $400-$700 in materials. A Kohler DTV+ thermostatic system with multiple spray functions runs $1,200-$2,500 in materials before installation. Both are reliable products from vetted lines we source regularly; the difference is comfort and convenience, not longevity.
- Accessibility features. Adding a fold-down teak bench, a linear grab bar, or a zero-threshold curb for aging-in-place adds $300-$1,200 to the project depending on what’s spec’d. In neighborhoods like Rancho Bernardo and Scripps Ranch where multigenerational households are common, we quote these additions on a significant portion of conversion jobs.
- San Diego permit requirements. A straight tub-to-shower conversion with no structural changes and no plumbing relocation generally does not require a permit under San Diego’s current residential code. But the moment a drain moves, a wall opens for blocking, or the project is part of a broader bathroom remodel, a permit is typically required. Rowan pulls permits when the scope demands it – the cost ($200-$500) is itemized in the written quote.

AfterEntry-Level vs. Mid-Range vs. Premium: What You Actually Get
These three tiers describe what a homeowner in San Diego typically sees at each price point. They’re not marketing categories – they’re what the line items add up to.
Entry Level: $4,130-$5,500
Tub removal and haul-away, cement board substrate (no membrane), prefab acrylic surround panel kit from a brand like Dreamline or comparable, acrylic shower pan, pressure-balance valve with fixed showerhead, framed sliding glass door. This is a functional, durable conversion. It won’t win a design award, but it’s dry, safe, and significantly more usable than the tub it replaced – particularly for anyone who rarely used the tub for soaking and is converting for daily shower use.
Mid-Range: $5,500-$8,500
Tub removal, Schluter Kerdi waterproofing membrane over cement board, 4″x12″ or 12″x24″ ceramic or porcelain tile walls, tiled shower floor with prefab niche, Kohler or Delta pressure-balance valve with handheld combo and rain showerhead, one tiled niche, semi-frameless or frameless glass door. This is where most San Diego homeowners land when they’ve owned the home for at least five years and are renovating for quality of life rather than just function. The tile work is what distinguishes this tier – it’s real, it lasts, and it doesn’t look like a rental.
Premium: $8,500-$11,800
Full waterproofing system, large-format porcelain or natural stone tile, custom linear drain with tile-inlay grate, thermostatic valve system (Kohler or Toto), handheld and rain showerhead on separate volume controls, two tiled niches, frameless 3/8″ tempered glass enclosure, built-in bench. The premium tier is common in La Jolla, Del Mar, and Carmel Valley where the bathrooms themselves are large and the resale market expects a finished look. The frameless glass alone adds $600-$1,200 over a framed door, and the thermostatic valve system adds another $500-$1,200 in materials.
Tub-to-Shower Conversion vs. Full Bathroom Remodel: When to Do Each
A Tub-to-Shower Conversion in San Diego is a targeted scope: remove the tub, build the shower in its footprint, leave the rest of the bathroom intact. It’s the right call when the vanity, floor tile, and toilet are in good condition and the tub is simply unused. Cost: $4,130-$11,800.
A full bathroom remodel – vanity, countertop, floor tile, toilet, shower, paint, sometimes lighting – runs $10,620-$33,040 in San Diego depending on size and finish level. If the bathroom needs more than the shower addressed, bundling the work into one project saves on labor mobilization and often on permitting as well. The written quote for each scope is separate so you can compare apples to apples before deciding.
A small bathroom remodel – typically a hall bath or guest bath under 50 square feet – runs $5,900-$14,160 and sometimes overlaps with conversion pricing at the upper end. The difference is scope: a remodel touches multiple systems; a conversion is surgical.
How to Save on a Tub-to-Shower Conversion in San Diego
A few honest ways to reduce cost without cutting into durability:
- Keep the drain where it is. If the conversion can be designed around the existing drain location, you avoid the $600-$2,000 plumbing relocation cost and eliminate a significant scheduling variable. A good contractor measures the existing drain before quoting and designs the pan to match when possible.
- Choose tile sizes that minimize cuts. Labor is charged partly by the hour and partly by complexity. A 12″x24″ tile on a standard 60″ alcove wall generates predictable cuts. A mosaic or 4″x4″ hex floor tile takes significantly longer to set. The tile itself may cost less per square foot, but installation time can add $300-$700. Ask for the labor breakdown by tile type before you commit to a pattern.
- Use a prefab acrylic surround for the walls. A quality acrylic panel kit – properly installed over cement board with the correct adhesive – lasts 15-20 years with minimal maintenance. It’s not tile, and it won’t look like tile, but for a second bathroom used by guests or kids, it’s a legitimate choice that saves $1,500-$3,000 over a tiled alternative.
- Go semi-frameless instead of fully frameless on the glass. A semi-frameless door with a frameless look on the face saves $300-$700 over a fully custom frameless enclosure. Most people can’t distinguish them from a foot away once the door is clean.
- Bundle with adjacent work if other repairs are pending. If the bathroom floor tile or vanity also needs attention, adding those to the same project often saves on demolition labor and sometimes on permit fees. Ask for a bundled quote to compare.

What to Expect During a Tub-to-Shower Conversion
Knowing the sequence of work helps you plan around it and tells you whether a crew is following best practice.
Day 1 – Demolition and inspection: The tub, surround, and any damaged substrate come out. This is when the real condition of the walls and subfloor is visible for the first time. If anything requires a change order – say, damaged cement board that wasn’t visible during the quote walkthrough – that change is documented in writing and requires your signature before any additional work starts. No exceptions under the Haven Standard.
Day 1-2 – Substrate and waterproofing: New cement board is screwed and taped, or a waterproofing membrane is applied depending on the specified system. In San Diego’s coastal corridor – Oceanside south through Pacific Beach and Ocean Beach – we almost always specify a full membrane system because the humidity and salt air accelerate moisture intrusion behind tile. The membrane is what keeps the wall structure dry for 20 years instead of 7.
Day 2-3 – Tile installation: Wall and floor tile is set in sequence, starting from the reference point established by the tile setter. Grout follows 24 hours after setting. On a standard alcove conversion with 12″x24″ wall tile and a 3″x6″ floor mosaic, this takes roughly a day and a half for an experienced crew.
Day 3-4 – Fixtures, glass, and finish work: Valve trim, showerhead, and any handheld hardware are installed after the grout cures. Glass enclosure is measured during demo and ordered for fabrication; frameless glass typically arrives 10-14 days after the order, so the crew installs everything else and returns for glass on a separate short visit.
Photo documentation: Every visit includes a documented photo record of the substrate condition before close-up, the waterproofing layer, and the finished work. You receive this record when the job is complete – not because you have to ask, but because it’s included as standard.
San Diego-Specific Considerations
San Diego is not a generic market for bathroom work. A few local conditions consistently affect how these projects are quoted and built:
Older housing stock in urban neighborhoods. In areas like North Park, South Park, Kensington, and Golden Hill, homes built between 1920 and 1960 often have original cast-iron tubs that weigh 300-400 pounds. Removal requires two people and sometimes partial wall disassembly to get a cast-iron unit out of a tight hallway – add $100-$300 over a standard fiberglass tub removal. We factor this into quotes when we know the tub type at the time of the walkthrough.
Slab construction in inland communities. In newer communities like Chula Vista, El Cajon, and Santee, homes built on concrete slabs require saw-cutting the slab if a drain relocation is needed. This is louder, dustier, and costs more than the same work in a home with a crawl space or raised foundation – typically $1,500-$2,500 for the combined concrete work and plumbing. We call this out in the initial quote when it applies.
HOA and condo considerations. In San Diego’s dense condo markets – Mission Valley, Bankers Hill, Little Italy – water intrusion from a bathroom renovation can affect units below. HOAs in these buildings frequently require a licensed contractor, sometimes with specific insurance documentation, and may require work to happen during restricted hours. Rowan carries the documentation these buildings ask for; if your building has specific HOA requirements, share them before the quote and we’ll confirm compliance in writing.
Permit thresholds. The City of San Diego’s Development Services Department has updated its residential alteration permit thresholds. As of 2026, work that includes moving a drain, relocating a valve, or opening walls for blocking generally requires a plumbing permit and may trigger an inspection. Work that stays within the existing footprint with no plumbing changes typically does not. We identify the permit requirement at the quote stage and include the cost when it applies.
Tub-to-Shower Conversion FAQs
How much does a tub-to-shower conversion cost in San Diego?
A tub-to-shower conversion in San Diego costs $4,130-$11,800 for most residential projects. Entry-level conversions with a prefab acrylic surround and basic fixtures run $4,130-$5,500. Mid-range tile conversions with a waterproofing membrane and semi-frameless glass run $5,500-$8,500. Premium custom tile, frameless glass, and thermostatic fixtures land at $8,500-$11,800. Call (858) 434-8926 for a written quote specific to your bathroom’s configuration – no estimate required to get a number.
How long does a tub-to-shower conversion take?
Most conversions take 3-5 business days for the core work – demolition, substrate, waterproofing, tile, and fixtures. If a custom frameless glass enclosure is spec’d, the glass fabrication takes 10-14 days from order. The crew returns for that final install visit; the shower is usable once grout has cured (typically 48-72 hours after tile completion) without waiting for the glass. Total calendar time from start to final glass install is usually 2-3 weeks for a custom job.
Do I need a permit for a tub-to-shower conversion in San Diego?
Not always. A tub-to-shower conversion in San Diego that uses the existing drain location, doesn’t relocate plumbing, and doesn’t involve structural wall changes typically doesn’t require a permit under current San Diego Development Services guidelines. But any work that moves the drain, opens a wall for blocking, or is part of a larger bathroom remodel generally does. Rowan identifies the permit requirement during the quote walkthrough and includes the permit cost in the written price when it applies – it won’t appear as a surprise line item after the job starts.
Is it cheaper to repair or replace the existing tub vs. converting to a shower?
Tub resurfacing costs $400-$900 and extends a tub’s life by 5-10 years if the underlying structure is sound. But if the tub sees minimal use and the goal is a functional daily shower, resurfacing is a short-term cost that delays rather than solves the problem. A conversion at $4,130-$11,800 is a permanent change that adds usable space, improves accessibility, and typically returns value at resale – particularly in San Diego’s market, where buyers in mid-range zip codes increasingly expect a walk-in shower in the primary bath. Call (858) 434-8926 and we’ll review both options against your specific bathroom layout before any work starts.
Can I keep the tub and add a shower in the same space?
Yes, if the tub footprint is large enough – typically 60 inches or longer – a tub-shower combo with a new valve and glass or curtain rod can be installed without removing the tub. This costs $1,200-$3,500 depending on the valve type and enclosure chosen, and it’s considerably less disruptive than a full conversion. The tradeoff is that the shower area is smaller and the tub remains as a floor-space occupant. For households that want the option of a soak bath and a functional shower in the same space, this is a legitimate middle path. A full conversion makes sense when the tub genuinely isn’t used and the priority is a larger, more open shower footprint.
Does a tub-to-shower conversion add value to a San Diego home?
In the primary bathroom, removing the only tub in the house can reduce resale appeal for buyers with young children – this is a genuine consideration in family-oriented neighborhoods like Scripps Ranch, Mira Mesa, and Eastlake. In a primary bath that has a second bathroom elsewhere in the home with a tub, converting the primary tub to a walk-in shower consistently adds value in the San Diego market. Real estate agents in North Park and Hillcrest routinely report that buyers in that price bracket prefer a large tile shower over a tub in the primary suite. The calculus depends on your home’s total bathroom count. If you’re unsure, Grant Rowan can walk through the layout with you at the quote appointment at no charge.

Why Rowan Construction Group for Your San Diego Conversion
Founded in 2007, Rowan Construction Group has delivered 4,000-plus projects across San Diego, every one with a written price before anyone picked up a tool. That discipline – which Haven made the centerpiece of the Haven Standard when they acquired Rowan – means the number you see on the quote is the number on the invoice. In 18 years of bathroom remodeling, roofing, windows, fencing, and home additions in this market, we’ve seen what happens when a contractor starts work without a signed scope: the customer finds out the real price when the walls are already open. We think that’s a bad system, so we built a different one.
Grant Rowan leads the team on every project type we offer. Background-checked, uniformed crews. A live person answering calls 24/7. A documented photo record on every visit, delivered to you as standard. And the 365-Day Done Right Promise: if it isn’t done right, we make it right – that’s printed on every page of the contract, not tucked behind an asterisk.
We also source from vetted material lines – Kohler and Toto fixtures, Schluter waterproofing systems, Dreamline and comparable glass enclosures – which is why the written quote has honest numbers in it rather than inflated ones. Sourcing from 50-plus vetted brands since 2007 means we know what materials actually cost in the San Diego market and we can put a real number in front of you.
If you’ve already received a quote from another contractor, bring it in. Our Free Second Opinion offer means we’ll review it line by line at no charge – no pressure, no sales process, just a straight read of what’s in the quote and whether the numbers make sense for the scope described.
