CGI Bathroom Remodeling: The San Jose Owner’s Guide
If you have a CGI bathroom and a part has failed, we stock and install CGI-compatible bathroom remodeling components in San Jose, with most full bathroom remodels running $10,620 – $33,040 depending on the scope, materials, and what’s behind the walls. The typical homeowner discovers a problem the same way every time: a fixture stops draining, a vanity door sags, or water starts showing up where it shouldn’t be. Trevor Nash and our Penhallow Remodeling San Jose team handle these jobs weekly, and we’ll give you a written price before any work starts.

Which CGI Models This Applies To

CGI bathroom products span several series lines, and the compatibility gotcha most San Jose homeowners hit is this: CGI’s mid-2000s vanity and shower lines used slightly different rough-in dimensions than their current catalog. If you’re replacing a CGI vanity from that era, the drain rough-in may sit 1.5 inches further back than modern standard, which means a standard off-the-shelf vanity won’t fit without wall or floor work. We measure first and order to the actual opening, not the brochure.
For OEM versus aftermarket parts on CGI bathroom components: OEM cartridges, hinges, and drain assemblies are worth the extra cost when the fixture is under 10 years old and in good shape. Once a shower valve body or a vanity cabinet box has failed, a quality aftermarket replacement from a recognized brand like Kohler or Moen often outperforms the OEM part and carries its own warranty. We’ll tell you which route makes sense for your specific CGI model before you spend a dollar.
Styles & brands we work with







Signs Your CGI Bathroom Remodeling Is Failing
- Water staining or softness at the base of the vanity or shower curb. This usually means the waterproofing membrane or the drain gasket has let go. By the time you see the stain, the substrate (the moisture-resistant layer behind your tile) is already wet. This one doesn’t fix itself.
- A shower valve that drips even when fully closed. The cartridge inside the CGI valve body has worn out. It’s a $40 – $120 part, but if you ignore it for six months, you’re replacing the valve body and the tile around it.
- Vanity door hinges that sag or strip out of the cabinet box. CGI’s older particleboard boxes don’t hold hinge screws well once they’ve been over-tightened. The fix is usually a hinge plate or a new cabinet box, not just a new screw.
- Grout that keeps cracking in the same lines. This points to movement in the subfloor or the shower pan, not the grout itself. Regrouting without addressing the movement is throwing money at a symptom.
- A bathroom exhaust fan that sounds louder than it used to. If it’s a CGI-installed fan, the bearing is going. A failing fan stops pulling moisture, and in San Jose’s cooler months, that moisture condenses and feeds mold in the wall cavity.
Replacement Cost & What’s Included

Here’s what we quote in San Jose, based on current labor and material costs:
- CGI vanity cabinet replacement: $945 – $3,540 installed, depending on width and whether we need to move plumbing
- CGI shower valve cartridge swap: $180 – $420 installed
- Full CGI bathroom remodel: $10,620 – $33,040, which covers demolition, waterproofing, tile or surround installation, fixtures, vanity, and finish work
- Small bathroom refresh (CGI fixtures, new vanity top, paint, hardware): $5,900 – $14,160
The range shifts based on what’s behind the walls. If the subfloor is solid and the plumbing rough-in matches, you’re at the low end. If we open the wall and find that failed waterproofing rotted the studs, the number moves. We write the price before we start, and if we find hidden damage, we stop and show you before any change order happens. Every CGI bathroom job carries our 365-Day Done Right Promise: if it fails inside a year, we come back and fix it at no charge, in writing.

You can safely inspect a CGI bathroom failure on your own: check under the vanity for water staining, run the shower and watch for drips at the valve, and push gently on the tile around the shower curb to feel for movement. That tells you what’s wrong. Fixing it is a different conversation. Shower valve cartridges mean shutting off water to the house and pulling a valve that’s been sitting in hard water since the day it was installed. Waterproofing failures mean demolition and rebuild, and a DIY patch job on a shower pan will leak again within a year and cost more to fix the second time. If you’re not sure what you’re looking at, call (669) 274-2362. We’ll tell you straight whether it’s a Saturday project or a contractor job, and there’s no charge for that conversation.
FAQs

In San Jose’s climate, expect 10 – 15 years from CGI shower valves and cartridges, 15 – 20 years from a properly waterproofed shower pan, and 20+ years from a vanity cabinet that hasn’t been exposed to water. Hard water shortens valve life. Coastal fog near the hills shortens everything that rusts.
A dripping cartridge can usually be repaired with a new cartridge. A failed shower pan or a rotted vanity cabinet box cannot be repaired in place; it must come out and be replaced. We’ll tell you which category yours falls into before quoting anything.
A cartridge swap takes about two hours including shutting down and re-pressurizing the water. A vanity replacement is one day. A full bathroom remodel runs two to four weeks, most of it spent waiting for thinset and waterproofing to cure properly. We give you a written schedule with the written price.
We stock common CGI-compatible valve cartridges, drain assemblies, and hinge hardware on our trucks. For full vanities, shower pans, and tile, we order from our San Jose suppliers with lead times of three to ten business days. We also work with KraftMaid, Cambria, and Silestone for countertops and cabinetry when a replacement makes more sense. Call (669) 274-2362 for an exact parts-and-labor quote; estimates are free.
