Ameristar Bathroom Remodeling: The Boca Raton Owner’s Guide
We stock and install Ameristar-compatible bathroom fixtures, vanities, and shower systems in Boca Raton with a typical installed range of $9,000-$28,000 for a full remodel, and we carry common replacement parts on our trucks for same-day repairs. Most Boca Raton homeowners discover an Ameristar component is failing when the vanity base swells near the sink trap, the shower valve develops a slow drip behind the tile, or the original particleboard cabinet floor softens from the humidity that sits above 70 percent eight months of the year here. The damage usually starts small and accelerates once the substrate is compromised.
Which Ameristar Models This Applies To
Ameristar produces builder-grade and mid-grade bathroom lines sold through wholesale distribution, not retail showrooms, which means the model identification is often on a sticker inside the cabinet rather than on the door face. We most commonly see the AMV series vanities (24-inch to 60-inch widths, 21-inch depth), the AMS shower valve trim kits (pressure-balanced, 1998-2016 production), and the AMC cultured-marble shower surrounds in Boca Raton homes built between 2004 and 2014, particularly in developments west of Lyons Road where Ameristar was spec’d by volume builders.
To identify your part: check the cabinet interior for a white or silver sticker with a code starting AMV, AMS, or AMC, then measure the rough opening width and depth. The AMV vanity tops are proprietary 19-inch depth, not the standard 22-inch, so a generic replacement top will overhang or leave a gap. For shower valves, the AMS series uses a Posi-Temp-compatible cartridge (1222B aftermarket equivalent fits), but the trim plate screw spacing is 7.25 inches center-to-center, not the Moen-standard 7.5 inches. We source OEM Ameristar parts through our wholesale channels, though for discontinued lines we fabricate compatible solutions from KraftMaid cabinet components or specify Cambria and Silestone surfaces when the original cultured marble has failed.
Signs Your Ameristar Bathroom Remodeling Is Failing

- Soft or discolored cabinet floor near the sink. The AMV series uses a 3/8-inch particleboard deck with a thermofoil skin; once the sink trap weeps or the shutoff valve seeps, the particleboard swells and loses structural integrity. We find this in roughly half the Boca Raton AMV vanities we open, especially in second bathrooms where exhaust fans are undersized.
- Shower valve drip that worsens when pressure fluctuates. The AMS pressure-balance cartridge uses a wax motor that degrades in hard water; Boca Raton’s municipal supply runs 120-180 ppm calcium, and we see cartridge failure at 6-10 years instead of the 15-year design life.
- Cultured-marble wall panels pulling from the corner seams. The AMC surround uses a silicone seam that fails when seasonal humidity swings cause the fiberglass backing to expand and contract. In west Boca Raton, where afternoon thunderstorms drive rapid humidity spikes, we see seam separation accelerate after year seven.
- Vanity door hinges sagging or binding. Ameristar spec’d 3/4-overlay Euro hinges with a 95-degree opening angle; the plastic bushing wears in high-humidity environments, and the door drops until it contacts the face frame. The fix is a specific 35mm cup hinge with a stainless-steel bushing, not the standard zinc version.
- Grout cracking in the shower floor within five years of installation. The AMC shower base has a slight flex in the 60-inch model when set on a standard mortar bed without full perimeter support; the movement transmits to the grout, which crumbles and allows water into the pan. We document this with a photo record before any tile removal begins.

AfterReplacement Cost & What’s Included
Our installed pricing for Ameristar bathroom work in Boca Raton follows the ranges below. Every quote is a flat written price with a written scope; under Clause 1 of the Haven Standard, no work starts until you have both in hand.
| Service | Installed Price Range |
|---|---|
| Full Bathroom Remodel | $9,000-$28,000 |
| Small Bathroom Remodel | $5,000-$12,000 |
| Walk-In Shower Installation | $4,500-$12,000 |
| Tub-to-Shower Conversion | $3,500-$10,000 |
| Shower Replacement | $3,000-$8,500 |
| Bathroom Vanity Installation | $800-$3,000 |
What drives the range: substrate condition (whether the AMV cabinet floor needs sistering or full replacement), tile demolition depth (one layer vs. two), and whether the AMS valve rough-in is standard depth or the shallow 1.5-inch version used in some 2006-2008 Boca Raton builds that requires wall reconstruction to accept a modern valve. Our price includes parts, labor, permit pulling, and disposal. We warranty the workmanship for one year under the 365-Day Done Right Promise, and fixture warranties pass through from the manufacturer. No change order is executed without your signature, which is the discipline that has kept our projects within a few percent of the agreed price across 4,000-plus jobs since 2007.
DIY or Call Us?

There is safe homeowner inspection and there is work that belongs to a licensed contractor. You can verify your model number, photograph the failure, and check the shutoff valves for operation. Do not attempt to remove a pressurized shower valve cartridge without isolating the house main; the AMS rough-in is thin-wall brass and cracks if the retaining nut is overtightened during reassembly. We have replaced three Boca Raton valves this year where a homeowner’s wrench slipped and split the body, turning a $340 cartridge job into a $2,800 wall-rebuild.
Vanity replacement involves water supply lines, drain alignment, and often a trapped escutcheon that must be cut free without damaging the supply stub. We carry the 19-inch-depth AMV-compatible tops, the corrected hinge hardware, and the AMS cartridge on our trucks. Call (754) 254-8065 to schedule your free estimate. We will review your photos, confirm parts availability, and give you a written price before anyone picks up a tool.
FAQs
With proper exhaust ventilation and annual caulk inspection, a full Ameristar bathroom remodel lasts 15-20 years in Boca Raton’s climate. The AMV vanity itself is the weak point; we upgrade the cabinet floor to marine-grade plywood as standard practice, which extends service life by roughly 40 percent in high-humidity conditions. Call (754) 254-8065 for an exact quote on your specific model - estimates are free.
Surface repairs are possible if the particleboard core is still solid; we can skin the cabinet interior with a waterproof panel and replace the hinge hardware. Once the floor is soft or the side panel is delaminated, replacement is more cost-effective than reconstruction because the AMV frame joinery relies on the particleboard for structural integrity. Call (754) 254-8065 and we will photograph the damage and give you both options in writing.
A vanity swap with no plumbing relocation takes one day; a full bathroom remodel with tile, valve replacement, and fixture upgrade takes 5-8 working days in Boca Raton, plus permit inspection scheduling. We do not promise same-day completion on planned construction work because permit inspections and substrate drying times are not negotiable. Call (754) 254-8065 for a written timeline with your quote.
We stock AMS cartridges, AMV-compatible hinge sets, and 19-inch-depth vanity tops in white and biscuit on our Boca Raton trucks. Full cabinet boxes and AMC shower surrounds are warehouse-ordered with a 3-5 day lead time, which we confirm before we schedule. Call (754) 254-8065 to verify availability for your model number - estimates are free.
