CGI Bathroom Remodeling: The San Francisco Owner’s Guide
We stock and install CGI-compatible bathroom remodeling components throughout San Francisco, with a typical installed project running $10,620 to $33,040 depending on scope, materials, and what’s behind the existing walls. Most owners discover their CGI bathroom parts have failed when tile starts separating at the seams, water pools where it never used to, or the shower pan flexes underfoot. The failure usually traces back to one preventable issue: water intrusion that sat too long against the substrate.
Our trucks carry the common CGI-compatible trim, pan, and rough-in hardware, so we can often start same week. Call (831) 610-5598 with your model spec, and we’ll pull the part before we even arrive.
Which CGI Models This Applies To
CGI has manufactured bathroom components across several lines over the years, and not every part swaps cleanly between them. The biggest gotcha in San Francisco is the older 1.6-gallon-per-flush era CGI rough-in valves, which used a different cartridge depth than the current low-flow models. Measure from the finished wall to the center of the existing valve body – if you’re under 2-1/8 inches, you’re on the older spec and need the adapter kit. Don’t assume the new cartridge drops in.
We ask every homeowner for the same three things before we touch a CGI bathroom job: the model label under the tank lid or behind the escutcheon plate, a photo of the existing rough-in, and the wall depth. That tells us whether we’re doing a direct OEM swap or a field-fitted retrofit. We use CGI OEM parts where they’re still manufactured, and quality aftermarket equivalents where the OEM line has been discontinued. Names we also keep in regular stock for adjacent work: KraftMaid for vanities, Cambria and Silestone for solid-surface tops.

Signs Your CGI Bathroom Remodeling Is Failing
- Tile grout cracking in a diagonal line from the valve body: usually means the CGI rough-in has shifted slightly and the tile assembly is taking stress it wasn’t designed to carry.
- Water staining on the ceiling below the bathroom: the pan gasket or drain flange has failed, and water is following the framing. In San Francisco’s fog-heavy Outer Sunset, this moves slowly and quietly until it doesn’t.
- Shower temperature swings when someone flushes a toilet: the pressure-balancing cartridge is worn. This is a 45-minute swap with the right CGI part, not a full remodel signal by itself.
- Caulk pulling away repeatedly at the pan-to-wall joint: the pan is flexing. That’s a structural warning sign, not a recaulking job.
- A hollow sound when you tap the lower wall tile: the backer board behind the enclosure has gotten wet and is decomposing. The visible tile is the last thing to tell you.

AfterReplacement Cost & What’s Included
Here’s how our San Francisco pricing breaks down for CGI bathroom remodeling work:
- Full bathroom remodel (CGI-compatible fixtures, pan, surround): $10,620 – $33,040
- Small bathroom remodel (toilet, vanity, CGI-compatible fixture replacement): $5,900 – $14,160
- Walk-in shower installation with CGI-compatible pan and valve: $5,310 – $14,160
- Shower replacement only (CGI pan, drain, cartridge): $3,540 – $10,030
Every estimate includes parts, labor, haul-away, and the written guarantee. We don’t do open-ended time-and-materials on this work. Before anything starts, you get a line-item scope with the part numbers, brand names, and a firm number. If we hit a hidden condition inside the wall – and in old San Francisco homes, that’s more common than not – we stop, show you what we found, and hand you a written price for the add-on before we proceed. No surprises at close-out. That’s the whole point.
DIY or Call Us?
You can safely check three things without calling anyone: the model label under the CGI tank lid, the shut-off angle stops at the wall (turn them a quarter turn to confirm they hold), and whether the pan surface feels spongy when you kneel on it. Those answers tell us a lot over the phone.
What you should not do is open the rough-in valve body yourself, especially in an older CGI install where the cartridge retaining clip has likely corroded into place. Break that clip, and you’re cutting into the wall to replace the entire valve assembly. That’s a $1,500 mistake made for the lack of a $45 retaining clip and the right extraction tool. If the finish trim is pitted or the valve is older than 15 years, let us do it. Call (831) 610-5598 and we’ll tell you straight what you’re looking at over the phone.
FAQs
CGI bathroom components typically last 15 to 20 years in San Francisco conditions, assuming the original install was done to spec. The variable is moisture exposure on the coast – in the Outer Sunset and Richmond districts, we see pan gaskets fail 3 to 5 years sooner than in the Mission or Noe Valley because of persistent humidity and micro-fog against exterior walls. A properly sealed and vented enclosure extends the life meaningfully.
CGI shower pans can be re-sealed in some cases, but the honest answer is that a pan that flexes or has visible stress cracks at the drain flange should be replaced. Sealing it buys a few months. Replacing it buys you the next 15 years. We’ll tell you which route is actually worth your money on the phone.
A straight CGI pan or cartridge replacement usually takes one day on site. A full CGI-compatible bathroom remodel runs 7 to 14 days depending on whether we’re moving plumbing, rebuilding substrate, or just setting new fixtures on sound framing. You’ll get a written timeline with your estimate, and it won’t drift.
We stock the common CGI cartridges, gaskets, and drain assemblies on our trucks. Rare or model-specific CGI trim pieces may be a two-day order. Tell us the model label over the phone – (831) 610-5598 – and we’ll tell you whether the part’s in the truck or incoming, before you schedule anything.
