AfterHow Much Does a Tub-to-Shower Conversion Cost in Sherman Oaks?
A tub-to-shower conversion in Sherman Oaks, CA typically costs between $3,500 and $10,000, with most homeowners landing somewhere around $5,500 to $7,000 for a standard alcove conversion with tile walls, a prefab shower base, and updated plumbing trim. The final number depends on the size of the space, the tile and fixture choices, and whether the existing plumbing needs to be rerouted – a common situation in Sherman Oaks homes built during the postwar tract-housing boom of the 1950s and 60s.
At Rowan Construction Group, every estimate is a written flat price with a defined scope – not a ballpark delivered over the phone. Under Clause 1 of the Haven Standard, no work starts until that number is on paper and you’ve signed off on it. That’s been true across every one of our 4,000-plus projects since 2007, and it’s the same approach we bring to every tub-to-shower conversion in Sherman Oaks.
Tub-to-Shower Conversion Cost Breakdown (2026)
A tub-to-shower conversion isn’t one line item – it’s five or six trades happening in sequence. The table below breaks down what each component typically costs in the Sherman Oaks market as of 2026, so you can see where the money goes before anyone picks up a tool.
| Cost Component | Typical Range (Sherman Oaks) | Notes |
|---|---|---|
| Tub removal and disposal | $200 – $500 | Cast-iron tubs cost more to haul; fiberglass/acrylic are lighter and cheaper to remove |
| Shower base / pan | $300 – $1,200 | Prefab acrylic at the low end; custom tile mud bed at the high end |
| Tile materials (walls and floor) | $400 – $2,500 | Standard ceramic vs. large-format porcelain or natural stone; price per square foot varies widely |
| Tile labor and waterproofing membrane | $800 – $2,200 | Includes Schluter Kerdi or similar membrane installation beneath tile; non-negotiable for California code compliance |
| Plumbing adjustment / trim | $400 – $1,500 | New valve, shower arm, and head; rerouting adds cost if drain location shifts |
| Shower door or enclosure | $500 – $2,000 | Frameless glass at the high end; rod-and-curtain at the low end |
| Permits and inspections | $150 – $400 | Los Angeles Department of Building and Safety requires permits when plumbing lines are altered |
| Drywall / cement board repair | $150 – $600 | Depends on condition of existing substrate once the tub surround is removed |
| Total estimate range | $3,500 – $10,000 | Most Sherman Oaks projects fall in the $5,500 – $7,000 range |
What Pushes the Price to the High End
In Sherman Oaks, the projects that reach $8,000 or above usually share a few characteristics. Large-format tile (anything 24×24 or bigger) requires more precise substrate prep and takes longer to install – that’s labor, not just material. Custom niche cutouts, built-in benches, and body spray fixtures all add plumbing and tile hours. And in older homes on streets like Kester, Cedros, or Ventura-adjacent blocks, we regularly find that the original cast-iron tub is sitting on a subfloor that needs patching before anything else happens. That substrate condition only becomes visible after demolition.
It’s also worth naming the waterproofing membrane specifically. Skipping a proper membrane – or using an undersized one to cut costs – is the most common reason shower conversions fail within five years. Every Rowan project uses a full membrane system beneath the tile layer, installed and documented before tile goes up. The photo record from that stage is part of your project file, not something we keep for ourselves.
What Keeps the Price Near the Low End
A straightforward conversion – existing plumbing in the right location, a prefab acrylic base, standard 3×6 or 4×4 wall tile, and a rod-and-curtain setup instead of glass – can come in at $3,500 to $4,500. These conversions are practical and durable. The material costs are honest, the labor hours are fewer, and the permit process is simpler when the drain location doesn’t move. If budget is the primary driver, this is a reasonable scope and there’s no shame in pricing it that way.
What Affects Tub-to-Shower Conversion Pricing in Sherman Oaks
Six factors move the number more than anything else in this market. Each one is knowable before work starts – which is exactly why we put them in writing.
- Plumbing configuration in the existing tub alcove. If the existing tub drain lines up with where the shower drain will sit, rerouting is minimal. If the drain needs to move more than a foot – common in 1960s Sherman Oaks construction where tubs were positioned for the era’s standard layout – expect to add $400 to $900 for a licensed plumber to adjust the line. That cost is in the written quote before anyone opens a wall.
- Tile selection and format. Ceramic subway tile costs roughly $2 to $5 per square foot in material; large-format porcelain runs $6 to $18 per square foot; natural stone (travertine, marble) can reach $20 to $40 per square foot before labor. A standard 60-inch alcove conversion uses approximately 60 to 80 square feet of wall tile, so the material difference between entry-level and premium tile alone can be $500 to $2,800. Rowan sources from more than 50 vetted suppliers, so the written quote reflects actual trade pricing, not inflated retail.
- Shower enclosure type. A simple tension rod and curtain adds almost nothing to the project cost. A framed glass door runs $500 to $900 installed. A frameless glass enclosure – the kind that shows off the tile work – typically costs $1,200 to $2,000 installed in Sherman Oaks, depending on glass thickness (3/8-inch vs. 1/2-inch) and hardware finish.
- Substrate condition behind the tub surround. This is the variable most contractors won’t name until demolition day. In Sherman Oaks homes with original tile surrounds from the 1970s or 80s, water intrusion over decades often means the cement board or drywall behind the surround has deteriorated. We document what we find with photos before any new material goes in, and any substrate repair is added via a signed change order – not as a surprise on the final invoice.
- Permit requirements under Los Angeles building code. Any conversion that moves the drain location, changes the valve position, or alters load-bearing elements requires a permit from the Los Angeles Department of Building and Safety. Rowan pulls permits as standard practice and factors the fee into the written quote. Unpermitted shower work can create complications during a home sale – a real concern in Sherman Oaks’s active resale market, where buyers and their inspectors look for red flags in bathrooms.
- Accessibility features. Curbless (zero-threshold) shower entries require a sloped floor and a more labor-intensive waterproofing setup than a standard curbed base. Built-in fold-down benches, grab bars anchored into blocking, and hand-held shower wands all add material and labor. These features are common in Sherman Oaks homes where a conversion is being done specifically to age in place or accommodate a household member with mobility needs. They add $500 to $2,000 depending on scope, but they’re knowable up front.

AfterTub-to-Shower vs. Full Bathroom Remodel: Which Makes Sense?
A full Tub-to-Shower Conversion in Sherman Oaks is a contained project – it stays inside the footprint of the existing tub alcove, uses the existing plumbing rough-in, and doesn’t require touching the vanity, floor tile, or lighting. That’s why the cost range ($3,500 to $10,000) is significantly narrower than a full bathroom remodel, which in Sherman Oaks runs $9,000 to $28,000.
The conversion-only approach makes sense when the rest of the bathroom is in good shape and the goal is simply to replace a tub nobody uses with a shower that’s actually practical. It also makes sense when the budget is a real constraint – a clean conversion with durable materials is a better outcome than a full remodel done with cost-cutting in every corner.
Where a full remodel starts to look more logical is when the vanity is also dated, the floor tile is cracked or original to the 1970s, or the lighting is inadequate. Doing the tub conversion and leaving the rest of the bathroom untouched can produce an uneven result. That’s a conversation worth having before the quote is written, not after.
If you’re still deciding between the two scopes, our home page outlines all seven trades we cover and how the written-price process works across each one – that context can help you think through sequencing if a larger project is on the horizon.
How to Save on a Tub-to-Shower Conversion in Sherman Oaks
There’s a right way and a wrong way to reduce cost on this project. The right way is choosing materials and features deliberately. The wrong way is cutting corners on waterproofing, skipping permits, or hiring unlicensed labor – all of which create far larger costs down the line, either through failed tile work or through disclosure problems when the house sells.
Here’s where deliberate choices actually move the number:
- Stay in the existing footprint. Keeping the drain in its current location and using the existing valve rough-in eliminates the most variable cost in a conversion: plumbing rerouting. If the tub alcove is a standard 60-inch three-wall setup, a competent contractor can work within that footprint without touching the drain line. Ask specifically whether the quote assumes drain relocation or not – that one question can reveal a significant cost difference between bids.
- Choose a prefab base over a custom mud bed. A factory-made acrylic or fiberglass shower base costs $300 to $600 and installs in a fraction of the time a custom-tiled mud bed requires. The aesthetic is different – less bespoke – but the function is identical and the durability is solid. For a secondary bathroom conversion, this is a practical choice.
- Select tile by the square foot, not by the look. A 4×12 ceramic subway tile at $3 per square foot and a designer 3×12 ceramic subway tile at $9 per square foot can look nearly identical once grouted. The difference on a 70-square-foot wall is $420 in material. Ask to see options at different price points before committing to a specific tile; the written quote will reflect whatever you choose.
- Defer the frameless glass enclosure. A rod and curtain is functional, and a frameless door can be added later as a separate project. If the budget is tight at the moment of conversion, getting the substrate and tile right is more important than the enclosure type. A properly waterproofed, well-tiled shower with a curtain rod will outlast a rushed conversion with a beautiful door.
- Get a second opinion on any written estimate. Rowan offers a free line-by-line review of any written competitor quote at no charge. Bring the estimate in; we’ll tell you if the scope is complete, if the materials specified match the price, and if anything is missing. This offer is open to anyone in Sherman Oaks, whether or not they end up working with us. Call (213) 221-0788 to set that up.
- Bundle with other bathroom work when possible. If the vanity or toilet also needs replacing, doing those items at the same time as the shower conversion reduces mobilization costs – one crew visit, one permit application where applicable. The savings aren’t dramatic, but they’re real. Ask whether a combined bathroom scope changes the line-item pricing in the written quote.
Sherman Oaks-Specific Considerations
Sherman Oaks sits in the San Fernando Valley, and the housing stock here is specific enough that a few local patterns come up consistently in tub-to-shower projects.
Most homes in the Woodbridge Park, Hazeltine, and Kester neighborhoods were built between 1948 and 1970. The original bathrooms in these homes typically used cast-iron tubs (heavy, expensive to remove) with ceramic tile surrounds set directly over gypsum drywall – not cement board or a waterproofing membrane, because those weren’t standard practice then. When the surround tile comes off, the drywall behind it often shows moisture damage. This isn’t a disaster; it’s a known condition that we document, price in a change order, and repair before any new material goes up. But it is something a Sherman Oaks homeowner should anticipate as a potential add-on cost of $150 to $600 depending on extent.
The San Fernando Valley’s summer heat also matters for curing. Tile grout and mortar both cure faster in high heat, which sounds positive but actually increases the risk of premature drying before proper adhesion occurs. Proper installation technique in Sherman Oaks summers means managing cure conditions carefully – particularly in bathrooms on south-facing walls or in homes without effective HVAC in the bathroom itself. This is a trade-practice note, not a crisis, but it’s the kind of thing a contractor with Valley experience accounts for and a contractor without it may not.
Los Angeles Department of Building and Safety jurisdiction applies to all Sherman Oaks permits. Standard tub-to-shower conversions that don’t move plumbing and don’t alter structural elements often fall below the permit threshold – but any time a drain relocates or a valve is repositioned, a permit is required. Rowan’s written quotes specify whether a permit is included in scope and at what cost, so there’s no ambiguity after the fact.
Key Takeaways
- Tub-to-shower conversion in Sherman Oaks costs $3,500 to $10,000; most projects land between $5,500 and $7,000.
- The biggest cost drivers are plumbing rerouting, tile selection, and substrate condition – all of which are documented before work starts.
- Permits are required when plumbing lines are altered; unpermitted work creates real liability in Sherman Oaks’s active resale market.
- Waterproofing membrane installation (Schluter Kerdi or equivalent) is non-negotiable for a durable result and is standard in every Rowan project.
- Older Sherman Oaks homes (pre-1975) frequently require substrate repair behind the original tub surround – budget $150 to $600 for this contingency.
- A written flat price before work starts, signed change orders for any additions, and a documented photo record at each stage are included on every project.
- The 365-Day Done Right Promise applies: if it’s not done right, Rowan makes it right, backed by the Haven Standard in writing.
FAQs – Tub-to-Shower Conversion Cost in Sherman Oaks
How much does a tub-to-shower conversion cost in Sherman Oaks in 2026?
A tub-to-shower conversion in Sherman Oaks costs between $3,500 and $10,000, with the midpoint for most standard projects sitting around $5,500 to $7,000. That range covers tub removal, a new shower base, tiled walls with proper waterproofing membrane, plumbing trim, and a basic enclosure. Premium tile, frameless glass, or accessibility features push the number higher; keeping the existing plumbing configuration and choosing a prefab base pulls it lower. For a written price specific to your bathroom, call (213) 221-0788 – the estimate is free and delivered on paper before any work is scheduled.
Does a tub-to-shower conversion require a permit in Sherman Oaks?
It depends on the scope. Conversions that stay within the existing plumbing rough-in – meaning the drain and valve positions don’t move – often don’t trigger a permit requirement under Los Angeles Department of Building and Safety rules. But any relocation of the drain line, repositioning of the valve, or structural work does require a permit, and the fee in Sherman Oaks typically runs $150 to $400. Rowan’s written quote specifies whether a permit is included and at what cost. Skipping a permit when one is required creates real problems during a future home sale, and it’s not a shortcut we take.
How long does a tub-to-shower conversion take in Sherman Oaks?
Most tub-to-shower conversions take three to five business days from demolition through final inspection. Day one is typically tub removal and substrate assessment. Days two and three cover plumbing adjustment (if needed), membrane installation, and tile setting. Day four handles grouting and any door or enclosure installation. Day five is typically final inspection and touch-up. Substrate issues discovered after demo can add a day; custom tile with complex patterns or large-format installation takes longer to set properly. The written project schedule is part of the written quote package, so you know the expected duration before anyone starts.
Is it cheaper to repair or replace a damaged tub surround versus converting to a shower?
A tub surround repair – regrouting, replacing cracked tiles, recaulking – typically costs $300 to $900 in Sherman Oaks and makes sense when the tub itself is in good condition and the damage is surface-level. A conversion at $3,500 to $10,000 makes sense when the tub is never used, the surround has water damage behind the tile layer (common in pre-1980 Sherman Oaks homes), or the household needs a shower more than a soaking tub. The conversion produces a more useful bathroom in most cases; the repair is the right call when the existing fixture is genuinely valued and the substrate is sound.

What’s included in Rowan’s tub-to-shower conversion service in Sherman Oaks?
Every Rowan tub-to-shower conversion in Sherman Oaks includes a written flat price with a defined scope delivered before work starts, tub removal and disposal, waterproofing membrane installation, tile setting, plumbing trim, the enclosure type specified in the quote, and a documented photo record at each stage of the project. Any change to the agreed scope – a substrate repair discovered after demo, a fixture upgrade requested mid-project – gets a signed change order before the additional work proceeds. The 365-Day Done Right Promise covers the finished work: if something isn’t right within a year, Rowan makes it right. Background-checked, uniformed crews handle every project, and a live person answers calls at (213) 221-0788 around the clock.
Can Rowan do a curbless (zero-threshold) shower conversion in Sherman Oaks?
Yes. Curbless conversions require a sloped floor – typically a 1/4-inch-per-foot pitch toward the drain – and a more involved waterproofing setup than a standard curbed base. In Sherman Oaks, this type of conversion typically adds $500 to $1,500 to the base project cost, depending on the floor area and the membrane system used. The benefit is significant for aging-in-place purposes or ADA-style accessibility. Rowan has completed curbless conversions in Sherman Oaks and nearby Valley neighborhoods, and the written quote will specify the slope design, membrane specification, and drain type so you know exactly what’s being built before work begins.
