CGI Bathroom Remodeling: The Los Angeles Owner’s Guide
Mason Remodeling handles CGI bathroom remodeling across Los Angeles at an installed price range of $10,620 to $33,040. That range covers everything from a full gut-out rebuild with a new shower system to a complete master bath transformation using CGI’s compatible fixture and surface lines. Most Los Angeles homeowners discover they need this level of work when a shower pan cracks, a vanity frame has swollen past saving, or the existing tile substrate behind the wall has finally let moisture through to the studs.
CGI isn’t a plumbing or fixture manufacturer. It’s a cabinetry and storage line, and over the past several years we’ve seen a steady stream of Los Angeles bathrooms where CGI cabinet boxes or vanity bases were installed against poorly waterproofed walls or floors. The cabinet fails first, but by the time you see it, the water damage behind and beneath it has usually gone further. That’s why a CGI bathroom job in Los Angeles is rarely a simple cabinet swap. It’s often a rebuild of the wet zone around it.
If you’re standing in a bathroom with swollen CGI cabinet bases, doors that no longer seat, or a vanity that has begun pulling away from the wall, call (803) 680-2547. We’ll give you a written price before any work starts, and you’ll know exactly who is walking through your door.
Which CGI Models This Applies To
CGI’s cabinet and vanity program was built for production homes and mid-range remodels, which means most of what we see in Los Angeles comes from two or three cabinet series that were installed in volume ten to fifteen years ago. The critical detail with CGI is the box construction. Many CGI lines use particleboard or medium-density fiberboard cores with a vinyl or thermofoil wrap. They are dimensionally stable when dry. They fail fast when wet.
We install and rebuild around all CGI bathroom vanities, linen cabinets, and storage towers. When you have an existing CGI piece that needs to be matched, we look for the manufacturer label inside the cabinet door or on the side of the drawer box. That label will give you the series, color code, and door profile. If the label is gone, we measure the drawer face thickness, the door overlay, and the interior depth. CGI bathroom vanities typically run 18 to 21 inches deep, which is shallower than a standard kitchen cabinet and one of the reasons off-the-shelf replacement doors rarely fit.
One compatibility gotcha we see regularly in Los Angeles: CGI bathroom vanity widths often come in odd increments like 31 or 37 inches, sized to fit production home rough openings. You cannot drop a stock 30-inch vanity into a 31-inch CGI opening without modifying the wall or adding a filler that looks wrong. We either reface to the original CGI door profile or rebuild the cabinet opening to a clean standard dimension. That decision affects cost and timeline, and it’s one of the first things we resolve on a site visit.
Mason Remodeling is an independent contractor. We are not affiliated with CGI or any cabinet manufacturer. We also work with KraftMaid, Cambria, and Silestone lines, which matters when you want a bathroom that mixes a CGI storage piece with a Cambria quartz top or a Silestone sill.

Signs Your CGI Bathroom Remodeling Is Failing
- Swollen or darkened cabinet bases near the floor. This is the number one call we get in Los Angeles. Water from shower overspray or a slow toilet leak wicks into the particleboard core. Once the box swells, the door gaps shift and the cabinet cannot be saved with paint or patches. The subfloor often needs drying or repair at the same time.
- Vanity doors that no longer close square or rub at the corners. Moisture has changed the cabinet’s geometry, or the wall behind it has moved. In older Los Angeles homes with lath-and-plaster walls, we sometimes find the cabinet was hung on a wall that was already out of plumb and shimmed badly. The fix is a re-hang or full replacement.
- Thermofoil peeling at edges or drawer fronts. CGI’s wrapped doors delaminate once heat and humidity get behind the vinyl layer. Los Angeles bathrooms without proper ventilation push enough moisture into the room to start this process within a few years. Peeling cannot be glued back cleanly. The doors get refaced or replaced.
- White residue or softening at the toe kick. You are looking at mineral staining from standing water. The cabinet base is compromised, and there is a good chance the drywall behind it is holding moisture too. This is the failing part we tell Los Angeles homeowners to address now rather than after mold spreads to the wall cavity.
- A vanity pulling away from the wall, especially around a sink cutout. Water has reached the wall anchors or the cabinet back itself. When the sink is heavy and the box fails, you get sag at the front edge. That is a structural failure, not a cosmetic one, and it’s the point where a full bathroom remodel becomes cheaper than repeated spot repairs.

AfterReplacement Cost & What’s Included
In Los Angeles, a complete bathroom remodel tied to a failed CGI cabinet runs $10,620 to $33,040. The lower end covers a small bathroom with a new vanity, new flooring, a toilet, and new plumbing trim. The upper end includes a full gut-out of the wet zone, waterproofing, a new shower system, custom tile, a larger CGI or equivalent cabinet layout, and updated electrical. If the job stays focused on cabinet replacement only, it falls inside the bathroom vanity installation range of $945 to $3,540, but most CGI failures in Los Angeles are not cabinet-only jobs once we open the wall.
What drives the price: whether the shower or tub surround gets rebuilt, whether the subfloor needs replacement, how far the water has traveled, and whether plumbing or electrical work requires a permit. With CGI specifically, refacing existing cabinet boxes is often cheaper than full replacement, but only when the boxes are dry and square.
Every proposal from Mason Remodeling includes a written, line-item price before any work starts. No verbal estimate that grows at the end. The crew arrives with name and photo sent in advance, in clean uniform, with a photo ID badge at the door. That is the Threshold Standard, and it applies on every job. The completed work is covered by our 365-Day Done Right Promise: if it isn’t right within a year of completion, we fix it at no cost to you.
DIY or Call Us?
You can safely unload the vanity, shut off the angle stops, and pull the drawers to see how far the swelling goes. You cannot safely assess the wall cavity behind it. The dangerous part of a CGI bathroom failure is what you cannot see: wet electrical boxes, softened subfloor under a heavy toilet, or mold inside a wall that has been damp for months. If any of that is present, a tile saw and a good attitude are not going to fix it.
We see the same pattern across Los Angeles: a homeowner opens the wall on a Saturday, finds a plumbing leak or an electrical splice that was never to code, and calls us Monday morning with a bigger problem and a smaller budget. The cheapest fix today is the one that actually stops the water and rebuilds the wet zone correctly. Know who’s coming, know what it costs, know it’s backed up – everything else is just noise. Call (803) 680-2547 and we will send someone who treats your bathroom, and your home, with the care it deserves.
FAQs
In a properly ventilated Los Angeles bathroom, a CGI vanity with a particleboard core typically lasts 10 to 15 years before moisture begins to degrade the box. In bathrooms with poor exhaust or a family of four showering daily, that lifespan can drop to 7 or 8 years. Call (803) 680-2547 and we will assess whether yours is worth saving or ready for replacement.
No, not once the particleboard has swollen. Swollen particleboard has lost its structural integrity and cannot be sanded, clamped, or dried back into shape. The surrounding framing and wall cavity often need targeted repair at the same time, which is exactly what we inspect before giving you a written price.
A focused vanity and flooring replacement typically takes 3 to 5 working days. A full bathroom gut-out with shower rebuild usually runs 2 to 3 weeks depending on permit timing and tile work. We give you a written schedule with your written price, so you know both numbers before you sign anything.
We do not stock CGI brand cabinet boxes or doors, because most failed CGI pieces are not worth re-creating with the same particleboard construction. We keep demolition, waterproofing, and plumbing repair materials on the truck so a first visit can often stop active damage the same day. For replacement fixtures and cabinetry, we order specification-grade products and give you the lead time in writing before work begins. Call (803) 680-2547 for a free estimate.
