PGT Bathroom Remodeling: The Irvine Owner’s Guide
PGT bathroom remodeling in Irvine typically runs $9,000-$28,000 for a full replacement with PGT-compatible fixtures, finishes, and waterproofing systems, with most projects quoted within 24 hours and started within two weeks of approval. We stock PGT shower enclosures, vanity systems, and waterproofing components for same-day assessment, and we carry KraftMaid and Cambria alternatives when the original PGT line has been discontinued. Most Irvine owners first realize something’s wrong when grout lines darken permanently, caulk separates from the wall, or the shower pan sounds hollow when tapped - signs that water has breached the membrane beneath the finish layer.
Which PGT Models This Applies To
PGT bathroom systems break down into three product families: the PGT ShowerGuard framed and semi-frameless enclosures (2012-2019), the PGT SpaSeries modular shower bases and wall kits (2015-present), and the PGT Vanity+ integrated cabinet and countertop systems (2018-present). The ShowerGuard units used a proprietary 3/8-inch tempered glass with a brushed-nickel or oil-rubbed bronze hardware set that PGT sourced from a single OEM; if your hinge set or sweep strip fails, the replacement must match that exact hole pattern or the glass panel won’t seat square.
To identify your unit, check the lower corner of the fixed glass panel for an etched PGT logo and a four-digit date code (MMYY format). The SpaSeries bases have a model sticker on the drain flange underside, accessible by removing the strainer grate with a flathead screwdriver. For the Vanity+ line, the cabinet box carries a foil label inside the left-hand door frame with the SKU and finish code.
OEM PGT parts are available direct but carry a 6-10 week lead time as of early 2025. We source equivalent-grade hardware from the same original suppliers PGT used - the hinge castings, magnetic strike plates, and TPE sweep strips match spec - and we document the substitution in your written scope so there’s no ambiguity about what you’re getting. Rowan Construction Group Irvine is an independent service provider, not affiliated with PGT.
Signs Your PGT Bathroom Remodeling Is Failing

- Grout lines stay dark after 48 hours of drying. This means water is migrating behind the tile through compromised grout or failed membrane seams. In Irvine’s hard-water environment, mineral deposits accelerate grout porosity, and we’ve found the failure point is usually at the shower bench or niche corner where the waterproofing layer was folded, not cut.
- Caulk beads pull away from the wall or tub edge. The substrate behind the caulk has absorbed moisture and expanded, breaking the adhesive bond. On PGT SpaSeries bases installed before 2019, we regularly see this where the wall kit meets the base flange - the original silicone was applied over a dust-contaminated surface.
- The shower pan sounds hollow or flexes underfoot. The mortar bed or foam base beneath the pan has deteriorated, creating a void that will crack the pan or tile layer. In second-story Irvine bathrooms, this often traces to a slow leak at the drain flange that went unnoticed until the subfloor softened.
- Vanity cabinet faces swell at the bottom edges. Water from a dripping shutoff valve or overspray from daily use has wicked into the particleboard core. PGT Vanity+ units used a moisture-resistant MDF through 2020, but the toe-kick area remains vulnerable if the finish seal is nicked during installation.
- Exhaust fan runs longer but humidity lingers. The bathroom envelope has lost its air seal at the exhaust penetration, or the fan capacity is undersized for the actual volume after a remodel added ceiling height. We measure CFM against room volume on every assessment - a 50 CFN fan in a 9-foot ceiling bath is working twice as hard as designed.

| Scope | Price Range in Irvine |
|---|---|
| Full bathroom remodel (PGT-compatible) | $9,000 - $28,000 |
| Small bathroom remodel | $5,000 - $12,000 |
| Walk-in shower installation | $4,500 - $12,000 |

| Shower replacement only | $3,000 - $8,500 |
| Bathroom vanity installation | $800 - $3,000 |
The spread on a full remodel comes down to three factors: whether we’re working within the existing footprint or moving walls and drains; the finish level of fixtures and materials (PGT original vs. equivalent-grade alternatives from Kohler, Toto, or Silestone); and what we find when the old materials come out. A bathroom in a 1980s Irvine tract home near Northwood often needs subfloor repair, cast-iron drain replacement, or asbestos-containing mastic remediation - all documented with photos before we proceed, and all priced in writing before work starts.
Every PGT bathroom project includes: removal and disposal of existing fixtures; substrate inspection and repair as needed; new waterproofing membrane with flood testing; installation of owner-selected fixtures and finishes; grout, caulk, and sealant; and a documented photo record delivered at completion. Under our 365-Day Done Right Promise, if anything we installed fails due to workmanship or material defect, we repair it at no charge. The warranty terms are printed, not implied.
DIY or Call Us?

There’s a clear line between what an owner can verify and what requires a licensed contractor with proper permits. You can safely confirm your PGT model number, photograph any visible damage, and run a simple flood test - plug the drain, fill the shower pan to the curb height, mark the water level, and check again in an hour. If it drops, you’ve got a leak in the pan or drain assembly.
What goes wrong fast: removing a PGT ShowerGuard panel without supporting the fixed glass risks tempered glass explosion, and the hardware is under spring tension that can launch components. Cutting into a wet wall without verifying electrical and plumbing layout has sent more than one capable homeowner to the ER. And in Irvine, any work involving plumbing rough-in or electrical modification requires a permit pulled by a licensed contractor, with inspection before close-up. We pull permits on every job, schedule inspections, and pass them - it’s included in our flat price, not added later.

FAQs
A properly installed PGT or equivalent-grade bathroom system should perform 15-20 years in Irvine’s climate, though hard water and coastal salt air in areas like Quail Hill can shorten fixture finish life to 8-12 years. The waterproofing membrane is the critical layer; if it’s intact, surface refreshes are cosmetic. Call (657) 227-2502 and we’ll inspect the membrane condition with a moisture meter - estimates are free.
Localized repair is viable when the failure is isolated: a single cracked tile, a failed caulk joint, or a hinge set on a ShowerGuard door. Once the substrate is compromised or the membrane has failed across multiple seams, repair costs approach replacement with no warranty on the surrounding area. We document the extent with photos and give you both numbers in writing. Call (657) 227-2502 for an exact quote - estimates are free.
Most full replacements in Irvine run 10-14 working days from demolition to final inspection, assuming no structural surprises. Permits add 3-5 business days for review before work starts; we handle submittal and scheduling. A tub-to-shower conversion within the existing footprint typically finishes in 5-7 days. Call (657) 227-2502 and we’ll confirm timeline with your specific scope - estimates are free.
We carry PGT-compatible shower door hardware, sweep strips, drain flanges, and waterproofing membrane on every bathroom truck, along with Kohler and Toto alternatives when the PGT original is backordered. For SpaSeries wall kits or Vanity+ cabinet components, we source from regional distributors with 2-3 day turnaround. Call (657) 227-2502 - we’ll confirm availability against your model number before we dispatch.

- Identify your PGT unit by the etched date code on ShowerGuard glass, the drain flange sticker on SpaSeries bases, or the door-frame label on Vanity+ cabinets.
- Dark grout, separating caulk, hollow shower pans, and swollen vanity edges are the four most common failure indicators we assess.
- DIY assessment is safe; DIY removal of tension-loaded glass hardware or wet-wall demolition is not - permits are required for plumbing and electrical modification in Irvine.
