Ameristar Bathroom Remodeling: The Los Angeles Owner’s Guide
If you’re searching for Ameristar bathroom remodeling in Los Angeles, the most likely scenario is that you have a failing or outdated Ameristar product in your bath or shower and you need it replaced or rebuilt properly. A full Ameristar-compatible bathroom remodel in Los Angeles typically runs $10,620 to $33,040, depending on the size of the room and whether we’re doing a tub-to-shower conversion, a walk-in shower rebuild, or a complete gut. Most homeowners discover the problem the same way: a crack in the acrylic, a soft spot where water has been sitting, or a door track that no longer seals, and suddenly the question stops being “can we live with it” and becomes “who in Los Angeles actually knows these units.”
That’s the page you’re on. We’ll walk through which Ameristar models we see in Los Angeles homes, what fails first, what an honest price looks like, and when it makes sense to call a contractor rather than attempt a fix yourself.
Which Ameristar Models This Applies To
Ameristar has been sold through regional distributors and remodelers for decades, so you’ll see their units under several names. The ones that show up most often in Los Angeles are the Ameristar acrylic tub-shower combos, the one-piece shower stalls, and the tub surrounds that were installed in tract homes and mid-century apartments. The key identifier is usually a label printed on the backside of the wall kit or etched into the apron under the tub. If that label is gone, the wall thickness and the drain placement tell us a lot: older Ameristar tubs sit on a 1-1/2 inch drain line, and the acrylic is noticeably thicker than what you’d find in a big-box off-the-shelf surround.
You have two paths here. OEM Ameristar parts still exist for some lines, but availability in Southern California is spotty, and lead times from out-of-state warehouses can stretch to three or four weeks. For most homeowners, a quality acrylic surround from a manufacturer we trust is the better call. It’s cut and shaped on site to match the Ameristar footprint, and the material warranties travel with the new product, not with a patch. Graham Stein has seen enough Ameristar tear-outs to know that matching a 15-year-old panel to a brand-new one sounds easier than it is; the color has shifted, the dimensions are close but not identical, and you end up with a seam that collects soap scum forever. The clean answer is usually a full surround replacement, not a panel swap.
One compatibility gotcha worth knowing: Ameristar tubs from the early 2000s frequently used a non-standard 14-1/2 inch apron height, which is about half an inch shorter than today’s common 15-inch rough-in. A contractor who doesn’t measure before ordering the replacement tub ends up shimming the floor or cutting the apron. We measure first. That’s the difference between a one-week job and a three-week job.

Signs Your Ameristar Bathroom Remodeling Is Failing
- Soft spots in the tub floor or shower pan. This is the one that can’t wait. When the fiberglass backing under the acrylic starts to delaminate, the floor flexes underfoot, and every flex opens a micro-crack that lets water into the subfloor. In Los Angeles homes with raised foundations, that water runs straight into the crawlspace and you won’t see it until the joists are damaged.
- Caulk lines that won’t stay sealed. If you’ve re-caulked the same joint twice in a year, the surround is moving. That movement means the Ameristar wall kit is no longer tight against the framing, and no amount of silicone fixes a structural gap.
- Discoloration that doesn’t scrub off. Acrylic ages. Hard water in Los Angeles leaves mineral deposits, and once the gel coat is worn thin, stains soak into the acrylic itself. Cleaners make it worse, not better.
- A door or curtain track that’s pulling away. On Ameristar tub-shower combos with integrated tracks, the track is often anchored through the acrylic. When the screws loosen, they strip the acrylic, and the only real repair is a new surround.
- Mold or musty smell that returns after cleaning. That odor is coming from behind the wall. It means water has found a path past the surround and has been sitting against drywall or wood. By the time you smell it, the damage behind the Ameristar unit is usually bigger than the visible problem.

AfterReplacement Cost & What’s Included
In Los Angeles, the cost to replace an Ameristar tub or shower and remodel the surrounding bathroom generally falls between $10,620 and $33,040. The spread is driven by what’s actually behind the old unit once we open the wall. If the framing is dry and square, the job moves fast. If the subfloor is spongy or the studs show water damage, that work has to happen before any new acrylic goes in, and it adds real days and materials.
Here’s what we write into every Ameristar replacement quote before any work starts:
- Removal and disposal of the old Ameristar tub, surround, pan, or unit, including careful demolition that protects the rest of the bathroom.
- Framing and drywall repair behind the old unit, brought back to a clean substrate for the new surround.
- New acrylic or composite tub, shower pan, or walk-in shower from a manufacturer with a warranty you can look up by name.
- New valve, trim, and showerhead from Kohler, Moen, or Grohe, depending on your preference and the existing plumbing.
- Waterproofing system on every shower or tub surround, using Schluter products where applicable.
- Cleanup and a photo of the finished, cleaned space before the crew leaves, alongside your written scope.
Our written price is the promise. If it’s not on the paper, we haven’t agreed to it yet. What we quote is what you pay, and every completed project carries our 365-Day Done Right Promise: if something isn’t right after the job is done, we make it right.
DIY or Call Us?
There are things an owner can check without opening a wall: confirm the label on the Ameristar unit if you can reach it, note whether the drain is a standard 1-1/2 inch, and look for movement in the surround where it meets the tub deck. That information helps us give you a faster, more accurate quote over the phone.
But pulling an Ameristar tub or surround out is not a weekend project for a homeowner. The demolition alone involves a reciprocating saw next to copper supply lines, the tub is often set in mortar which means real weight, and if the drain assembly is original, it’s likely rotted at the coupling. I’ve fixed more than one DIY Ameristar removal where the owner cut through a supply line thinking it was a vent stack. The water damage from that mistake cost more than the entire re-tub would have, had we done it from the start. For a trap, a cart, and a couple of utility knives, you’re into a job that regularly takes our two-person crew two full days with proper tools and a truck outside.
Call us at (949) 850-9896 with the model info or just a photo of what you’re seeing. We’ll tell you over the phone whether it sounds like a full replacement, a surround-only fix, or something smaller, and we’ll give you an honest range before anyone schedules a visit.
FAQs
In our experience across Los Angeles, an Ameristar acrylic tub-shower unit lasts 12 to 18 years before the gel coat is visibly worn and water intrusion becomes a risk. Hard water shortens that lifespan, and homes with poor bathroom ventilation see failures closer to the 12-year mark.
Surface refinishing can buy you one to three years if the only issue is cosmetic wear on the acrylic. If the floor is soft, the surround is pulling loose, or there’s evidence of water behind the wall, a patch or a reglaze won’t fix the structural problem, and it may hide it just long enough for the subfloor damage to get worse. Call (949) 850-9896 and we’ll help you figure out which situation you’re in.
A straightforward tub-for-tub or tub-to-shower swap in Los Angeles usually takes three to five working days from demo to the photo of the cleaned-up finished bathroom. A full bathroom remodel that includes flooring, vanity, and lighting runs two to three weeks, depending on the scope on your written quote.
We don’t carry OEM Ameristar tubs or surrounds as stock, because the units vary enough by year and distributor that the wrong one is worse than none. What we do carry to every Los Angeles job is the full Schluter waterproofing line, common drain assemblies, and the fixtures from Kohler and Moen we install most often, along with the acrylic and composite options you’ll see named and priced on your quote before any work starts.
