CGI Bathroom Remodeling: The Redwood City Owner’s Guide
CGI bathroom remodeling in Redwood City typically runs $9,000-$28,000 installed, depending on whether we’re refreshing fixtures in a hall bath or reconfiguring a master with moving drains and custom tile. We stock CGI-compatible vanities, shower enclosures, and hardware series on our trucks, and most Redwood City replacements start within two weeks of the written quote. Most owners realize something’s wrong when water stains appear on the ceiling below, caulk lines separate from the wall, or a vanity door won’t square up anymore - signs that the original install is failing at the seams, not the parts themselves.
Which CGI Models This Applies To
CGI (California Glass & Interiors) built its reputation on frameless shower enclosures, mirrored vanity systems, and aluminum-framed bath hardware sold through regional distributors from the 1990s through the mid-2010s. We regularly see their Series 100 and Series 200 shower door hardware in Redwood City homes built during the 2003-2010 boom, particularly in the Stambaugh-Heller neighborhood and the Redwood Shores townhome clusters where builders spec’d CGI for cost control on volume jobs.
To identify your CGI part, check the hinge edge of shower doors for a stamped “CGI” and a two-digit series number. Vanity mirror clips typically carry a small oval logo on the backplate. The critical compatibility gotcha: CGI used two different wall jamb profiles - a 3/4-inch return and a 1-inch return - and mixing them causes doors to bind within six months. We carry both on the truck. For hardware, we source OEM-grade stainless replacements from CRL and Prime-Line that match CGI’s original hole spacing. For glass, we measure on-site and order tempered from our San Jose fabricator; CGI’s original supplier closed in 2019, so “OEM glass” no longer exists, but the spec is straightforward: 3/8-inch minimum thickness, polished edges, ANSI Z97.1 certification.
Signs Your CGI Bathroom Remodeling Is Failing

- Shower door sagging or dragging. The bottom pivot pin wears oval in its nylon bushing, usually after 8-12 years of hard water exposure in Redwood City’s mineral-heavy supply. The door catches the threshold, and owners compensate by lifting - which bends the header rail.
- Mirror blackening at edges or clips pulling from drywall. CGI’s original mastic-backed clips lose adhesion in bathrooms without exhaust fans, common in pre-2010 Redwood City builds. The mirror shifts, stress-cracks form, and eventually the clip tears through the paper face of 1/2-inch drywall.
- Water pooling outside the shower curb. The vinyl sweep on CGI’s frameless doors stiffens and cracks after 5-7 years of UV and chlorine exposure. Once the seal gap exceeds 1/8 inch, water tracks along the tile and finds the subfloor seam.
- Vanity drawer fronts delaminating or hardware holes stripped. CGI’s imported MDF-core vanities swell at the sink cutout from repeated splash-over, then the hinge screws lose purchase in particleboard. We see this most in second baths where kids use the sink.
- Grout cracking in a straight line near the shower enclosure. This indicates the CGI pan or curb has deflected - often from inadequate mortar bed support during original install - and the tile layer is moving independently of the substrate.

AfterReplacement Cost & What’s Included
A full CGI bathroom remodel in Redwood City runs $9,000-$28,000, with small bath refreshes at the lower end and master reconfigurations with moving plumbing at the upper. Here’s how that breaks:
| Component | Typical Range |
|---|---|
| CGI-compatible shower enclosure (frameless, 3/8″ glass) | $2,800-$5,500 |
| Vanity replacement with stone top | $1,800-$4,200 |
| Fixture set (valve, trim, toilet, two faucets) | $1,200-$3,500 |
| Tile floor and shower surround | $2,500-$8,000 |
| Labor, demo, haul-away, permits | $2,700-$6,800 |
What drives the range: whether we keep the existing layout (saves $2,000-$4,000 in plumbing), the tile grade selected, and whether the subfloor needs repair after we pull the old enclosure. Under Clause 1 of The Haven Standard, you get the full written price before anyone picks up a tool. Every CGI replacement carries our 365-Day Done Right Promise, and the photo record - every stage, every problem found, every fix applied - is included, not an upgrade.
DIY or Call Us?

There’s a safe middle ground here. An owner can check the pivot pin wear with a flashlight, confirm the sweep gap with a feeler gauge, and photograph any mirror clip looseness for our review. What we don’t recommend: removing a CGI frameless door solo. The panels weigh 80-120 pounds of unprotected tempered glass, and the header rail is spring-loaded into the wall jambs - release it wrong and the glass drops edge-first onto tile. We’ve replaced three homeowner-dropped panels in Redwood City in the past two years. Vanity demo runs into the same risk: electrical at the light bar, supply lines seized since 2005, and the sink trap that crumbles when twisted. If you’re handy, send us photos and we’ll tell you what’s safe to prep. For the rest, call (650) 560-7228 and we’ll schedule a walk-through with a written quote.
FAQs
A properly installed CGI-compatible remodel lasts 15-20 years in Redwood City’s climate, though exhaust fan quality matters more than most owners realize. The marine layer moisture and hard water accelerate hardware corrosion if humidity sits above 60 percent. Call (650) 560-7228 for an exact quote on your space - estimates are free.
Individual parts - pivot pins, sweeps, magnetic seals - can be swapped if the glass is intact and the header rail isn’t bent. Once the rail deflects or the glass is chipped, repair costs approach replacement and we recommend the full enclosure. Call (650) 560-7228 for an exact quote - estimates are free.
Most CGI bathroom replacements in Redwood City take 5-8 working days from demo to final, assuming no subfloor repair or plumbing relocation. Custom glass adds 7-10 days for fabrication. We don’t start demo until the glass is in hand, so there’s no dry-living gap. Call (650) 560-7228 to schedule your timeline.
We carry CGI-compatible hardware, sweeps, and pivot assemblies on every Redwood City truck. Glass is measured to spec and ordered from our San Jose fabricator; vanity and enclosure frames come from our San Carlos supplier. We don’t stock OEM CGI parts because the company no longer manufactures them, but our replacements match or exceed the original spec. Call (650) 560-7228 to confirm availability for your model.
