Ameristar Bathroom Remodeling: The Los Angeles Owner’s Guide

Ameristar bathroom remodeling in Los Angeles typically runs $10,620 to $33,040 installed, depending on the scope of the job and whether you’re replacing a single part or rebuilding the whole space. We carry Ameristar-compatible parts on our trucks most weeks and can usually match your failed component without waiting on a special order. Most homeowners discover a problem when a shower valve starts dripping behind the wall, a tub crack spreads across the apron, or a vanity door hinge finally pulls loose after years of hard water and valley heat.

The telltale sign is usually water where it shouldn’t be. Ameristar tubs and shower bases are solid products, but the seals around the drain assembly and the gaskets behind the valve plate wear out long before the porcelain or acrylic does. If you’ve got a musty smell in the bathroom or a soft spot in the subfloor near the tub, that part failed a while ago and you’re now dealing with the secondary damage. That’s the job we see most often in Los Angeles, and it’s one we’ve been fixing since Tom Barrett started this company in 1998.

Which Ameristar Models This Applies To

Ameristar manufactures a few different bathroom product lines, and parts are not always interchangeable across them. The two most common in Los Angeles homes are the standard builder-grade tub/shower combos (model numbers starting with AT or AS, usually stamped on the underside of the tub apron) and the slightly heavier Ameristar Elite series, which uses a thicker acrylic and a different drain shoe assembly. If you’re not sure which one you have, flip up the overflow plate and look for the model stamp on the back side of the tub wall. Two screws, one flashlight, and you’ll know in ninety seconds.

For most Ameristar bathroom parts, OEM is the right call when the part touches water. Generic aftermarket drain assemblies work, but the thread pitch on Ameristar drain shoes is slightly different from the big-box standard, and forcing a generic fitting can crack the tub basin. We’ve seen it. We stock OEM Ameristar drains, overflow plates, and valve trim kits, and we use quality aftermarket equivalents only for non-structural pieces like escutcheon rings and handle adapters. If it seals water, it comes from Ameristar or it doesn’t go in.

Signs Your Ameristar Bathroom Remodeling Is Failing

• Water staining on the ceiling below the bathroom. This almost always means the tub drain gasket has gone flat. The tub itself is fine, but the rubber ring that seals the drain to the basin has aged out. In Los Angeles, our dry air makes rubber brittle faster than coastal climates.
• A crack running across the tub floor or apron. Ameristar acrylic tubs can develop stress cracks if the mud bed underneath wasn’t set right at original install. Once the crack opens, water gets under the tub and rots the framing. This is a replacement, not a patch.
• Shower handle turns but no water or only cold water. The mixing valve cartridge has seized. Hard water in Los Angeles chews through Ameristar cartridges in six to eight years. Replacing the cartridge fixes it most of the time.
• Persistent mildew smell that comes back after cleaning. Water is pooling where it shouldn’t be, usually behind the valve plate or under the tub edge. The visible grout looks fine; the hidden gasket doesn’t.
• Vanity door won’t stay closed, or the hinge has pulled the screws out of the particleboard. Steam and humidity in small Los Angeles bathrooms swell the material over time. Once the screw holes strip, the door drops, and the fix involves more than tightening screws.

Replacement Cost & What’s Included

For Los Angeles homeowners, a full Ameristar bathroom remodel lands between $10,620 and $33,040. A smaller job, like swapping a tub for a walk-in shower or replacing a failed tub surround, runs closer to $5,900 to $14,160. Where you fall in that range depends on what’s behind the wall once we open it up, how far the water damage traveled, and whether you’re reusing the existing plumbing rough-in or moving fixtures.

Every estimate from Barrett & Sons is a line-item written quote. You’ll see the cost of the Ameristar parts, the labor, the tile, the trim, and the permit fees broken out separately. If we open the wall and find rot, you get a written change order with the new scope and the new price before we touch another stud. That’s how we’ve done it for 29 years, and it’s why people in Los Angeles call us back. Permits get pulled, inspections get signed, and the work carries our 90-Day Done Right Promise.

DIY or Call Us?

You can safely check a few things yourself: tighten the overflow plate screws, look for the model number, and run your hand along the tub apron for soft spots. That’s useful information to have before you call. What you should not do is pull the valve cartridge, cut into the wall behind the tub, or try to seal a crack with a tub repair kit from the hardware store. That last one’s a temporary band-aid on a structural problem, and it always fails. Water damage is not a DIY repair. By the time you can see it, the framing is already compromised, and a brother-in-law fix just means you pay for the mold remediation twice.

If the part failed and water’s involved, call a pro. Call Barrett & Sons at (877) 610-1318. Tom Barrett grew up in the San Fernando Valley and learned the trade at Los Angeles Trade-Technical College. He’ll be on your job, not just on the contract. We’ll do it right the first time, or we’ll come back and make it right.
