CGI Bathroom Remodeling: The Los Angeles Owner’s Guide
If you have a CGI bathroom and the original run is showing its age, Mason Remodeling Co Los Angeles handles the full replacement and remodel, with most complete CGI bathroom remodels in Los Angeles running $10,620 – $33,040 depending on size, waterproofing condition, and fixture selection. We are an independent contractor, not affiliated with CGI, but we work with CGI-compatible parts and materials every week across the city. Most owners discover the need when grout starts failing, the pan flexes underfoot, or a valve cartridge gives out and the replacement part is no longer on the shelf at the local supply house.
Which CGI Models This Applies To
CGI bathroom products span a few distinct eras, and the compatibility story changes depending on what you have. Early 2000s CGI tubs and shower pans were often acrylic over fiberglass with integrated flanges; mid-2010s and later units moved to solid-surface composites with different drain assemblies. Before any remodel or replacement, we look for the molded lot number on the underside of the pan or the backside of the tub apron. That number tells us which generation you have and whether the drain body is standard 2-inch ABS or the older 1.5-inch configuration.
For anyone pricing a repair versus a full remodel, the honest truth is this: CGI discontinued several older pan molds and trim kits, so the OEM part may simply not exist anymore. In those cases we recommend quality aftermarket equivalents that match the footprint and drain location, or a rebuilt pan set to the original dimensions. We also stock common replacement parts for other lines we service, including KraftMaid cabinetry, Cambria and Silestone surfaces. For CGI specifically, the compatibility gotcha is almost always the drain placement, not the pan size.

Signs Your CGI Bathroom Remodeling Is Failing
- Hairline cracks radiating from the drain. This is the classic failure point on older CGI acrylic pans. The factory drain is tightened from above, and years of foot traffic around the flange creates stress cracks that widen with every shower. Once water gets under the pan, the subfloor starts going.
- Soft spots or flexing underfoot. If the pan moves when you stand in it, the support mortar bed has probably separated or was never set correctly. Los Angeles homes on post-tension slabs still see this when the original install skipped the setting bed.
- Grout lines that stay dark after cleaning. Dark grout means water is penetrating and not drying out. In a CGI surround, that water is traveling behind the panel and down to the pan lip, which is exactly where mold and dry rot take hold in LA’s humid summer months.
- Failing valve cartridges and trim that no longer seats. CGI used a few different valve suppliers over the years. When the trim plate won’t sit flush or the handle has play, the part you need may be discontinued. We see this constantly on units from the 2008 – 2012 range.
- Visible rust or mineral staining at the drain collar. Los Angeles water is hard, and mineral buildup around the drain ring is normal but should clean off. Rust is different. Rust means the drain body or the screw posts underneath are corroding, and that is a water-damage warning, not a cleaning issue.

AfterReplacement Cost & What’s Included
A complete bathroom remodel in Los Angeles, including pulling the old CGI unit and rebuilding the wet area, runs $10,620 – $33,040. That range covers everything from a straightforward pan-and-surround swap up to a full gut with new waterproofing, tile, fixtures, and glass. The biggest cost drivers are whether the subfloor needs repair (very common once a CGI pan has been leaking), the waterproofing system you choose, and whether you’re moving any plumbing.
- Pan or tub replacement with surround: $5,900 – $14,160
- Full bathroom remodel, all fixtures: $10,620 – $33,040
- Walk-in shower conversion from tub: $5,310 – $14,160
- Shower replacement only: $3,540 – $10,030
Every Mason Remodeling Co Los Angeles project comes with a written price before any work starts. That is not a promotional offer; it is how we have run jobs since Isaac Pruett took over operations. Your quote lists parts, labor, and what we found during the inspection. No change orders unless you ask for something different after we start.
DIY or Call Us?
Some things you can check yourself: whether the drain collar spins freely, whether the pan flexes, whether the grout is intact. These are diagnosis steps, not repairs. What we advise against is attempting to pull a CGI pan or surround on your own. The drain assembly is often corroded to the point where removing it damages the subfloor opening, and once the pan is out, you are committed. We have fixed a fair number of DIY removals in Los Angeles where the homeowner ended up with a torn shower valve and a bathroom that was out of service for three weeks. If it is a cosmetic trim issue, replacement parts are cheap and we are happy to advise over the phone. If it is structural, call us at (213) 632-5711 and we will come look. The estimate is free.
FAQs
How long does a CGI bathroom unit last in Los Angeles?
A properly installed CGI pan and surround typically lasts 15 – 20 years in Los Angeles, but the pan usually fails before the surround because it takes the daily load and sits in water every day. If your unit is over 12 years old and shows drain-line cracks or flex, start planning for replacement rather than patching it.
Can a cracked CGI pan be repaired instead of replaced?
A surface crack can be epoxy-filled as a stopgap, but if the crack is near the drain or the pan flexes, it is not repairable. The pan’s structural integrity is already compromised. We will tell you which one you have after a 20-minute inspection. Call (213) 632-5711 to schedule it.
How long does it take to replace a CGI pan and surround?
In most Los Angeles homes, a pan and surround replacement takes two to three working days, plus 24 hours for the waterproofing to cure before tile goes in. A full bathroom remodel with a CGI tear-out typically runs three to five working days depending on flooring, glass, and finish selection.
Do you stock CGI-compatible parts on the truck?
We keep the most common drain assemblies, trim plates, and valve cartridges for CGI-era units on the trucks. If you need a discontinued OEM part, we will tell you honestly and recommend the aftermarket equivalent that matches. No one should pay OEM prices for a part that was discontinued for a reason.
If your CGI bathroom is failing, the cheapest fix is the one you do before the subfloor goes. Call Mason Remodeling Co Los Angeles at (213) 632-5711 for a free inspection and a written estimate. Know who’s coming, know what it costs, know it’s guaranteed – everything else is just noise.
