Ameristar Bathroom Remodeling: The Riverside Owner’s Guide
Ameristar bathroom remodeling in Riverside typically runs between $9,000 and $28,000 installed, depending on the size of the bath, the fixtures you choose, and what’s hiding behind the walls once we open them up. We stock and install a full range of Ameristar-compatible tubs, surrounds, and wall systems, and we can usually have your remodel scheduled within two to three weeks of the written estimate. Most Riverside homeowners call us after they notice a crack in the tub shell, a soft spot in the surround, or water staining on the ceiling below the bathroom.
Ameristar products are solid, but nothing lasts forever, especially in Riverside’s hard water and temperature swings. Older Ameristar tubs and surrounds from the early 2000s were built with thinner acrylic than current production, which means hairline cracks and flexing are more common in homes around the Arlington and Canyon Crest neighborhoods than people expect. We’re an independent service provider, not affiliated with Ameristar, but we work with their components every week and know the product line well.
Which Ameristar Models This Applies To
Ameristar’s tub and surround lines share enough DNA that most Riverside homes fall into one of three groups: the original builder-grade two-piece tub-shower, the mid-grade one-piece surround with the molded shelves, and the higher-end Ameristar Elite series with the deeper soaking tub. The quickest way to identify what you have is to check the back side of the apron (the front face of the tub) for a stamped model number, usually starting with a letter code like AS or AE. If you can’t find it there, look under the overflow plate. That’s the little chrome disc below the faucet with two screws; the model tag is often tucked behind it.
Here’s the compatibility gotcha that trips up a lot of homeowners: Ameristar changed their drain position on several models around 2015. If your tub is older than that, you can’t simply drop in a new Ameristar tub of the same “size” without reworking the drain rough-in. That’s a $400 to $900 line item on its own. We always verify the drain center measurement before we order anything, because a return trip to the supply house is exactly the kind of thing we don’t want on a Riverside job. OEM Ameristar parts are what we recommend for tubs and surrounds still under warranty; for older units where warranty has lapsed, there are quality aftermarket surrounds that hold up just as well and cost 20 to 30 percent less.
Styles & brands we work with
Signs Your Ameristar Bathroom Remodeling Is Failing
- Hairline cracks in the tub floor or sidewalls. This usually means the original installer didn’t set the tub in a proper mortar bed, so the acrylic is flexing under weight. The crack will keep growing until the tub is reset or replaced.
- Bouncy or “spongy” feeling when you stand in the tub. Same story: missing or settled mortar base. Every bath we redo in Riverside gets a full mortar bed, regardless of what was there before.
- Water stains on the ceiling below the bathroom. This is the one that makes people flinch, and it should. It usually points to a failing drain gasket or a hairline crack at the tub-to-drain connection, not the tub itself. The good news is that’s often a repair, not a replacement.
- Peeling or bubbling surround panels. Moisture has gotten behind the surround, which means the adhesive or the backer board has failed. Once you see bubbles, the wall cavity is already wet and the problem is bigger than the panel.
- Mold or mildew that keeps coming back along the tub edge. In Riverside’s dry air, recurring mold at the tub line is a sign that water is wicking behind the surround. No amount of caulk fixes that from the outside.

AfterReplacement Cost & What’s Included
Ameristar bathroom remodeling in Riverside runs $9,000 to $28,000 installed, as we mentioned up top. The spread is wide for a reason. Here’s the line-by-line breakdown:
- Basic tub-and-surround swap: $9,000 to $13,000. Existing drain position works, minimal drywall repair, standard Ameristar tub and surround.
- Mid-range remodel with new valve, fixtures, and tile accents: $14,000 to $18,000. This is the most common Riverside job: tub or walk-in shower, new mixing valve, porcelain tile or solid-surface surround, new trim kit.
- Full gut remodel with layout changes: $19,000 to $28,000. Moving the drain, re-framing, walk-in shower conversion, built-in niche, heated floor, custom glass.
Every estimate includes a written line-item price before any work starts, labor and materials separated, so you know exactly what the number covers. The penalty for a change order mid-job is zero, because our price doesn’t change once we’ve agreed to it. We pull permits when the scope calls for it, and every Riverside remodel carries our 365-Day Done Right Promise: if something we installed fails inside the first year, we come back and make it right at no charge, in writing.
DIY or Call Us?
Ameristar tub and surround work is not a weekend project. The tub alone can weigh 120 pounds, and maneuvering it through a Riverside hallway without damaging the shell takes two people who have done it before. A full tub replacement also means pulling the drain, dealing with the waste-and-overflow assembly, and often cutting into the wall to get the old unit out. The only things we’d suggest a homeowner do themselves are the simple checks: turn the water supply off and on at the stops to confirm they still work, look for visible water stains around the base of the tub, and snap a photo of the stamped model number under the apron so you have it when you call us.
The safety concern here is straightforward: an improperly set tub flexes, the flex cracks the shell, and the crack lets water into the framing where you can’t see it. That’s how a $900 tub swap becomes a $6,000 rot repair. If you’re seeing any of the signs above, call (341) 895-1170 and we’ll take a look. The estimate is free, and we’ll tell you honestly whether you need a full remodel or a targeted repair.
FAQs
An Ameristar tub with a proper mortar bed underneath it should last 15 to 20 years in Riverside. Without the mortar bed, we see failures at 8 to 12 years. Hard water shortens the finish life either way, which is why we recommend sealing the surround joints with 100% silicone every couple of years. Call (341) 895-1170 if you want us to inspect yours and tell you what’s left in it.
It depends on where the damage is. Small scratches and chips in the acrylic can be buffed and filled with a color-matched repair kit. Cracks in the tub floor cannot be reliably repaired, because the flex that caused them is still there underneath. We’ll always tell you if a repair will hold before we suggest pulling the whole unit. Call (341) 895-1170 for an honest assessment.
A tub-and-surround swap usually takes 3 to 5 working days from demo to final caulk. A full gut remodel with tile and glass runs 2 to 4 weeks depending on scope and material lead times. We give you a written schedule with your written price, and the arrival window is in there too. Call (341) 895-1170 to get your timeline.
We keep common Ameristar drain assemblies, overflow plates, and trim kits on the truck. Full tubs and surrounds are ordered per job so you get the right model and size, and the order is confirmed by your written estimate before we schedule the work. If you need extras like a matching shelf or grab bar, call (341) 895-1170 and we’ll check our inventory or get it on the next truck.
We also work with other trade brands including KraftMaid, Cambria, and Silestone when the project calls for it.
Give you a number before we pick up a tool. That’s just how this works. Trevor Nash’s approach to estimating comes from the trade program at Los Angeles Trade-Technical College, where he learned early that a good remodel starts with knowing exactly what you’re walking into before you swing a hammer. His crew has spent years on Riverside projects, including older homes in the Arlington neighborhood where what’s behind the walls is rarely what the last contractor left behind.
If your Ameristar tub or surround is showing its age, call (341) 895-1170 to schedule your free written estimate. A real person answers the phone, the price goes on paper, and if it’s not done right inside a year, we come back and fix it.
