Oldcastle Bathroom Remodeling: The West Palm Beach Owner’s Guide

Oldcastle bathroom remodeling in West Palm Beach typically runs $9,000-$28,000 for a full replacement, with most projects quoted within 24 hours and started within two weeks of signed agreement. We stock and install Oldcastle-compatible shower enclosures, vanity systems, and waterproofing components, sourced through our network of fifty-plus vetted material brands. Most West Palm Beach homeowners first notice trouble when grout lines crack after summer humidity cycles, or when the shower pan membrane fails and water stains appear on the ceiling below.

Which Oldcastle Models This Applies To

Oldcastle manufactured bathroom products under several series names between the late 1990s and roughly 2018, when they shifted focus to their core building materials division. The most common lines we encounter in West Palm Beach homes are the Oldcastle Bath Solutions framed shower enclosures (model prefix OBS-2000 through OBS-4500), the solid-surface vanity tops sold through regional distributors in the mid-2000s, and the waterproofing membrane systems branded for commercial-to-residential conversion.

To identify your exact model, check the aluminum frame extrusion for a stamped code near the bottom hinge, or the vanity underside for a paper label with a lot number starting with OC or OBS. The shower enclosures used a proprietary 5/16-inch glass thickness in the OBS-3000 series, while the OBS-4000 upgraded to 3/8-inch - a critical difference when ordering replacement hardware, as the hinge bore spacing changed by 3/4 inch. We source OEM-tracked hardware where available, but for discontinued lines we spec equivalent-grade components from our KraftMaid and Kohler supply channels, documented in your written quote so you know exactly what arrives.

Signs Your Oldcastle Bathroom Remodeling Is Failing

• Grout cracking along shower corners or floor joints. In West Palm Beach, the daily humidity swing from 90% morning air to 72°F conditioned interiors stresses cementitious grout. Oldcastle’s original spec called for sanded grout without polymer additive, which we’ve found crumbles faster here than in drier climates. The underlying cause is usually movement at the pan-to-wall joint as the house settles on Florida’s sandy substrate.
• Soft drywall or bubbling paint on the ceiling beneath the bathroom. This indicates the shower pan membrane has breached. Oldcastle’s bonded membrane systems from the 2000s used a PVC composite that degrades with repeated chlorine exposure; we see this most often in second bathrooms where teenage swimmers rinse off.
• Vanity top staining or surface crazing (fine spiderweb cracks). The solid-surface material Oldcastle sourced was an acrylic-modified polyester that yellows under UV if the bathroom window faces west, as many do in Flamingo Park and El Cid neighborhoods. Crazing happens when thermal expansion exceeds the material’s flexibility.
• Door sweep dragging or frame misalignment. The OBS-series enclosures used a nylon-bottom sweep with a 5-year typical lifespan in hard water; West Palm Beach’s municipal water runs 120-180 ppm calcium, which crystallizes in the sweep channel and jams the door.
• Musty odor persistent after cleaning. This points to water trapped behind the tile or surround, often from failed caulk at the fixture penetrations. Oldcastle’s original silicone spec was neutral-cure, which bonds poorly to the porcelain-coated steel tubs common in 2004-2012 construction.

Replacement Cost & What’s Included

Full Oldcastle bathroom remodeling in West Palm Beach runs $9,000-$28,000, with small bathroom projects starting at $5,000-$12,000. The table below breaks out what drives that range.

Every quote from Rowan Construction Group West Palm Beach is a flat written price with line-item scope, delivered before any work starts - Clause 1 of The Haven Standard. The price includes demolition to studs where needed, new waterproofing membrane (we use liquid-applied systems with fabric reinforcement, not sheet goods), installation, and finishing. Our 365-Day Done Right Promise covers the workmanship; manufacturer warranties on materials like Kohler fixtures or Cambria tops transfer directly to you. No change proceeds without a signed change order, which is why our projects finish within a few percent of the agreed number.

DIY or Call Us?

There’s honest work a homeowner can do before calling. Check the shower door sweep for calcium buildup - soak it in white vinegar and see if the door moves freely. Verify whether the musty smell correlates with shower use versus general humidity; a dehumidifier test for 48 hours will tell you. Measure your glass thickness with a caliper if you’re ordering replacement hardware yourself.

Where DIY goes wrong is anything involving the waterproofing layer. Removing tile to access a failed membrane means disturbing the vapor barrier, and reapplying liquid membrane requires a 72-hour cure window with controlled humidity - nearly impossible in an active West Palm Beach household in July. We’ve been called to three jobs this year where the homeowner’s membrane application looked correct but failed the flood test because the substrate moisture content was too high at application. The rework cost more than our original quote would have.
