AfterHow Much Does Tub-to-Shower Conversion Cost in San Jose?
A tub-to-shower conversion in San Jose typically costs between $4,130 and $11,800 for a standard 60-inch alcove replacement in 2026. Most homeowners in the San Jose area pay around $7,500 for a mid-range conversion using solid-surface walls and a custom glass door. The final number depends on whether you’re replacing just the tub footprint or expanding the shower footprint, rerouting plumbing, and upgrading waterproofing methods.
San Jose’s housing stock drives a lot of this. Homes built between the 1950s and 1980s in neighborhoods like Willow Glen, Cambrian, and Almaden Valley often have cast-iron drain lines and plaster walls that add labor hours to any bathroom job. Newer homes in Evergreen or Berryessa tend to have cleaner subfloors and code-compliant plumbing that keeps costs at the lower end of the range.
At Bradford Remodeling Co San Jose, we give every homeowner a written price for tub-to-shower conversion in San Jose before any work starts. That number includes materials, labor, demolition, disposal, and waterproofing. No allowances that balloon later. No door-price adjustments. The price we hand you is the price the job costs.
Tub-to-Shower Conversion Cost Breakdown (2026)
Here’s how a typical San Jose tub-to-shower conversion breaks down line by line. These ranges reflect what we’re seeing across the South Bay market in 2026, from starter conversions to premium jobs with expanded footprints and custom finishes.
| Line Item | Low Range | High Range | Notes |
|---|---|---|---|
| Demolition & Disposal | $450 | $1,200 | Tub removal, wall board tear-out, haul-away. Older cast-iron tubs add weight and labor. |
| Plumbing Rough-In | $700 | $2,800 | Moving the drain from tub location to center-shower, replacing the valve, upgrading supply lines. |
| Shower Pan & Drain | $600 | $1,500 | Pre-sloped acrylic or custom mortar bed with PVC pan liner. |
| Wall Substrate & Waterproofing | $800 | $2,200 | Cement board or foam backer with liquid membrane or sheet membrane up to 72 inches. |
| Wall Surround Material | $900 | $4,500 | Acrylic on the low end, large-format porcelain or natural stone on the high end. |
| Shower Valve & Trim Kit | $250 | $900 | Single-handle pressure-balanced valve with trim. Thermostatic valves run more. |
| Glass Door & Hardware | $800 | $2,400 | Standard framed door vs. semi-frameless or frameless with stainless hardware. |
| Tile Labor (if tiled) | $0 | $3,500 | Not applicable if using solid-surface panels. Tile adds $12 – $25 per square foot for labor. |
| Permit & Inspection Fees | $300 | $700 | San Jose requires a plumbing permit for any drain or valve relocation. |
| Finish Work & Trim | $250 | $800 | Threshold, caulking, escutcheon plates, shower rod or mounting hardware. |
| TOTAL | $4,130 | $11,800 | Mid-range jobs with tile and frameless glass fall between $7,000 and $9,500. |
What pushes a job toward the high end? In our experience working across San Jose, three things move the needle most. First, moving the drain. A standard tub drain sits at the wall; a shower drain sits center-pan. That means cutting into the subfloor and reconfiguring the P-trap and drain line. Second, expanding the footprint. If you’re stealing space from a linen closet or bumping a wall to get from 30-by-60 to 36-by-60 or larger, you’re paying for framing, drywall, and floor patch on top of the shower work. Third, material choices. A Kohler acrylic surround runs less than a floor-to-ceiling porcelain tile installation with a Schluter waterproofing system underneath.
One thing we flag for every San Jose homeowner: if your house was built before 1985, budget for the possibility that the subfloor under the tub has moisture damage. We don’t know until the tub comes out. If we find rotted wood, we document it, show you photos, and bring you a change order with a written price before we do anything. The Garrison Standard, which Bradford Remodeling follows on every job, means no surprise work gets done without a signed number in your hand.
What Affects Tub-to-Shower Conversion Pricing in San Jose
Here are the factors that determine where your conversion lands between $4,130 and $11,800.
- Drain relocation. This is the single biggest cost variable. Keeping the drain at the wall end (a linear drain setup) costs less than moving it center-pan, which requires subfloor cutting and new DWV plumbing. On slab-foundation homes in South San Jose, moving a drain means cutting concrete, which adds $800 to $1,500 by itself.
- House age and substrate condition. San Jose homes built before 1985 often have drywall or greenboard behind the tub surround, which is not acceptable substrate for a shower. We strip it to the studs and install proper backer board. Homes from the 1990s and later sometimes have moisture-resistant drywall that’s also not rated for wet areas, so we replace it regardless.
- Shower footprint. A standard 60-inch tub-to-shower swap keeps the toilet and vanity where they are. If you want a 36-by-48 or 42-by-60 custom footprint, expect to pay more for layout changes, floor patching, and door placement.
- Wall material. Solid-surface panels from brands like Kohler or Corian run $900 to $2,500 installed depending on pattern and panel count. Tile runs higher because it requires waterproofing, setting time, and grout work. Large-format tiles (24-by-48 or bigger) cost more in labor because they’re harder to set flat.
- San Jose permit requirements. Any time you touch the drain or the shower valve, the City of San Jose building department wants a plumbing permit. That means an inspection mid-project, which is a good thing for you. It also adds $300 to $700 in fees and scheduling. Some contractors skip permits. We don’t. Bradford Remodeling pulls permits on every bathroom job that requires them, which is nearly all of them.
- Access and site conditions. Second-story bathrooms in Almaden or Blossom Valley homes mean hauling debris down stairs and carrying materials up. Single-story Ranch-style homes in Cambrian and Campbell-adjacent neighborhoods are faster jobs with less labor.
How the Bradford Approach Works on a Tub-to-Shower Conversion
The process starts with a phone call where a live person answers, 24 hours a day. You describe the bathroom, we schedule a site visit. Our technician shows up in a uniform, ID’d, and background-checked. You walk through what you want: door style, wall material, storage options like shower niches, seat, grab-bar blocking, valve type.
From there, our team builds a written specification: exact materials, exact scope, exact price. Nothing verbal, nothing vague. The Garrison Standard, which has governed Garrison Partners family businesses since 2004, requires a written price before any work starts. No exceptions. That price covers the full conversion, and it doesn’t move at the door or halfway through the job.
We install name-brand materials with traceable specifications: Kohler and Moen for fixtures and valves, Schluter or Laticrete for waterproofing systems, and major manufacturers for solid-surface wall panels. Every material has a manufacturer spec sheet and warranty backing. On top of that, the 365-Day Done Right Promise covers the full completed conversion for one year from job close. If the work fails inside that window, Bradford returns and corrects it at no charge. You get that guarantee in writing, signed, when the job is done.
“Squared away” at job close looks like this: the site is clean, the shower works, the permit is signed off by the San Jose inspector, and you hold a written guarantee in your hand. That’s the standard. No exceptions, no arguments.
How to Save on a Tub-to-Shower Conversion
You don’t need to chase the cheapest bid to keep a conversion reasonable. Here’s what actually saves money without cutting corners.
- Keep the footprint. Sticking with the 60-inch tub footprint eliminates framing changes and keeps the project on the lower end of the range. Every inch you expand adds cost.
- Choose solid-surface walls over tile. A quality acrylic or solid-surface surround can cut $1,500 to $3,500 off the total compared to a tiled installation. You give up some customization, but you gain easier upkeep and fewer grout lines.
- Use a standard glass door. Framed and semi-frameless doors cost less than custom frameless. If you like the heavy-glass look, compare prices on fixed panel plus door configurations before committing.
- Plan the valve, not the car wash. A single-function pressure-balanced valve with a handheld on a slide bar gives most of the daily comfort at a fraction of the cost of a multi-function thermostatic system with body sprays.
- Ask about written change order policy. Surprises in the wall are where unprincipled contractors make their margin. Bradford’s policy: subfloor damage or unexpected framing gets documented, priced, and signed before any additional work. You know the cost before we spend your money.
- Get one fixed number. Multiple visits from multiple contractors mean multiple estimates that may not compare line by line. A single thorough written estimate from a contractor who actually shows up is worth more than three vague bids.

Tub-to-Shower Conversion vs. Walk-In Shower: What’s the Difference?
People sometimes confuse a tub-to-shower conversion with a walk-in shower installation. They’re related but not the same thing.
A tub-to-shower conversion means you have an existing bathtub and you’re removing it, then building a shower in that space. The work involves tub demolition, drain relocation, wall rebuild, waterproofing, and shower finish. It’s a conversion because you’re changing the fixture type.
A walk-in shower installation can happen in a space that was always meant to be a shower, or in a new addition, or as part of a larger bathroom remodel. If there’s no tub to remove, the labor and disposal costs drop. If there is a tub, it’s a conversion.
In San Jose, the price ranges overlap. A conversion runs $4,130 to $11,800. A walk-in shower installation on a fresh footprint runs $5,310 to $14,160, because new footprint work often includes adjusting walls, relocating fixtures, and more finish trim. When homeowners ask us which makes sense, the answer usually comes down to one question: does anyone in the house still use a bathtub? If not, the conversion typically adds more usable square footage and better accessibility for the same or lower cost than a fresh shower build.
FAQs – Tub-to-Shower Conversion Cost
Is it cheaper to convert a tub to a shower or replace the tub?
A tub-to-shower conversion costs $4,130 to $11,800, while a straightforward tub replacement runs $2,000 to $5,500 in San Jose. If you never use the tub, the conversion gives you a better daily experience for the money. If resale matters and the home has no other tub, keep at least one bathtub somewhere in the house. Call (669) 272-2637 if you want us to walk your bathroom and give you a straight written comparison.
How long does a tub-to-shower conversion take in San Jose?
Most conversions in San Jose take 5 to 8 working days from demolition to final inspection. Jobs with tile, custom glass, or subfloor repair run longer. Bradford Remodeling provides a written schedule with the estimate so you know exactly when the shower is usable.
Do I need a permit for a tub-to-shower conversion in San Jose?
Yes, if the drain or water lines move. The City of San Jose requires a plumbing permit for drain relocation, which is standard on almost every conversion. Permit fees run $300 to $700. Bradford pulls the permit, schedules the inspection, and handles the paperwork. You never have to chase city hall.
Can I convert a tub to a shower for under $5,000 in San Jose?
Yes, a basic conversion using an acrylic surround, standard valve, and framed glass door can land around $4,130 to $5,000 if the subfloor is clean and the drain moves without complications. Shower replacement jobs, where some plumbing already exists, can run even lower at $3,540 to $5,000. But anything with tile, custom glass, or a moved footprint will go higher. Call (669) 272-2637 and we’ll tell you exactly where your bathroom falls.
Does a tub-to-shower conversion add value to a San Jose home?
In San Jose’s real estate market, a well-executed tub-to-shower conversion typically returns 60% to 70% of its cost at resale, with the biggest return coming from homes where at least one other bathtub remains. For homeowners planning to stay in the house, accessibility and daily comfort usually outweigh resale math.
How much does a shower replacement cost compared to a full tub-to-shower conversion?
A shower replacement in San Jose runs $3,540 to $10,030, while a tub-to-shower conversion runs $4,130 to $11,800. The difference is the tub demolition, drain relocation, and additional wall work. If you already have a shower and just want new walls, door, and valve, the replacement route is often $1,500 to $2,500 less.
San Jose Neighborhood Pricing Notes
Pricing shifts modestly across the city. Homes in Willow Glen and Rose Garden tend to be older, with lath-and-plaster walls that take longer to demo and produce more debris, pushing labor cost up. Almaden Valley and Silver Creek homes built in the 1980s and 1990s often have fiberglass tubs over plywood subfloors that come out cleanly. Downtown San Jose condos present a different challenge: HOA restrictions, freight elevator scheduling, and limited parking for debris bins all add coordination time to a job.
The $4,130 to $11,800 range holds across all of these areas. What changes is where you land within it.
What to Ask Any Contractor Before a Tub-to-Shower Conversion
Before you sign anything, get answers to these questions. A contractor who can’t answer them clearly is a risk.
- “Is the price in writing, and does it cover everything?” If the answer involves verbal assurances or “allowances,” walk away. Bradford Remodeling gives a written scope and written price before any work begins.
- “What waterproofing system do you use?” The answer should be specific: Schluter Kerdi, Laticrete Hydro Ban, Wedi panels, or similar. “We use plastic behind the tile” is a red flag in a wet area.
- “Do you pull permits?” The correct answer is yes. San Jose requires it for plumbing changes. A contractor who won’t permit is cutting a corner that puts your house at risk.
- “What’s your written guarantee?” Bradford’s 365-Day Done Right Promise covers the full conversion for one year, in writing. If it fails, we return and fix it free. Get whatever guarantee they offer on paper.
- “Who is actually doing the work?” Bradford sends background-checked, uniformed technicians. You know who’s in your home before they arrive.
