CGI Bathroom Remodeling: The Fresno Owner’s Guide
CGI bathroom remodeling across Fresno typically runs $9,000 to $28,000 installed, depending on whether you’re refreshing a small hall bath or gutting a primary suite down to the studs. We stock CGI-compatible materials on our trucks and can usually start a bathroom remodel within two to three weeks of the written estimate. What most Fresno homeowners notice first isn’t a single failed part, it’s a series of small surrenders: grout that keeps cracking along the pan line, a CGI shower base that flexes underfoot, a valve that drips even after new cartridges, or tile that has gone from bright to permanently cloudy because the waterproofing behind it stopped doing its job years ago.
A bathroom doesn’t usually fail all at once. It fails in the places you can’t see until the smell or the stain shows up on the ceiling below. By the time a Fresno homeowner calls us about a CGI bathroom, they’ve usually already tried caulking it twice and watched the caulk fail twice. That’s not a caulk problem. That’s a substrate problem, and it needs a remodeler who understands how CGI products are built to be installed, not just patched.
Which CGI Models This Applies To
CGI makes shower pans, wall surrounds, and bathroom component systems that come in a few distinct product lines, and the compatibility details matter more than most homeowners expect. The older CGI acrylic and fiberglass pan lines use a specific drain assembly with a rubber compression gasket that sits inside a 2-inch schedule 40 ABS or PVC waste pipe. The newer solid-surface CGI bases often drain through a different collar altogether. If you have the original paperwork, the model number is usually printed on a sticker underneath the pan lip, behind the access panel, or on the inside of the vanity-side wall surround. If you don’t, we measure the drain offset, the curb height, and the flange depth before we order anything.
OEM CGI components are the safest match when you’re replacing a pan inside an existing surround, because third-party pans rarely line up with CGI’s specific flange geometry without a shim job that voids the waterproofing. For valve trim, showerheads, and non-structural trim pieces, quality aftermarket products from Kohler, Moen, and Grohe work well and often carry better finish warranties than OEM trim. The one place we won’t cut corners on a CGI bathroom remodel in Fresno is the waterproofing layer underneath. Our crews install Schluter Kerdi or equivalent sheet membranes on every wet wall, because Fresno’s hard water and dry summers will find any gap in a liquid-applied membrane within a few seasons.
One compatibility gotcha we run into often: CGI pans built before roughly 2012 used a slightly narrower threshold profile than current models. If you order a replacement door for an older pan, the sweep won’t seat correctly. We always measure the threshold width with a caliper before ordering glass. It’s a two-minute check that saves a two-week reorder.

Signs Your CGI Bathroom Remodeling Is Failing
- The shower pan flexes or squeaks when you step in. This means the mortar bed underneath has cracked or was never set correctly in the first place. Flex eventually opens hairline cracks in the pan flange and lets water into the subfloor. In Fresno’s dry climate the water evaporates fast, but the rot it leaves behind doesn’t care about the humidity level.
- Grout keeps cracking along the pan-to-wall transition. That joint moves every time the pan flexes, and no grout or caulk can outlast a moving substrate. The fix is to stabilize the pan, not to re-grout the same line a third time.
- The drain develops a slow, stubborn clog that snaking doesn’t fix. When the rubber compression gasket on an older CGI drain degrades, hair and soap get caught on the broken lip instead of passing through. It looks like a clog. It’s actually a failed gasket.
- You smell mustiness in the vanity or the wall behind the shower. Water is getting past the waterproofing layer and sitting inside the wall cavity. By the time you smell it, the paper on the drywall has already started to feed mold. This is the one we tell Fresno homeowners not to wait on.
- Tile in the lower third of the shower is permanently discolored or the grout stays dark after drying. That’s water wicking up from behind the tile, not surface staining. Sealing the grout will trap the moisture inside and make it worse. The waterproofing plane has failed and needs to be rebuilt.

AfterReplacement Cost & What’s Included
A full CGI bathroom remodel in Fresno sits in the $9,000 to $28,000 range, and where you land depends on three things: the size of the wet area, whether you’re moving plumbing, and what level of finish you want on the dry side. A standard 5×8 hall bath with a new CGI pan, surround, valve, and tile floor runs $9,000 to $14,000. A primary bath with a custom walk-in shower, freestanding tub, double vanity, and heated floor lands between $18,000 and $28,000. Every estimate from Elmstead Remodeling Fresno includes a written line-item price before any work starts, so you’ll see exactly what the pan costs, what the labor costs, and what the waterproofing costs. No allowances that drift. No change orders unless you ask for the change.
Every CGI bathroom remodel we do includes the demolition and disposal, the new pan and waterproofing, tile or surround installation, fixture installation, and a full clean-up with shoe covers and drop cloths on every visit. The work is backed by our 365-Day Done Right Promise, which means if something isn’t right after we leave, we come back and make it right. We also photograph the clean-up before the crew packs the truck, so you can see the house was left the way we promised.
DIY or Call Us?
There are things a Fresno homeowner can safely check before calling us. You can remove the drain cover and look for visible damage to the rubber gasket with a flashlight. You can watch the pan flex when you step in and compare it to how it felt when the bathroom was new. You can pull the escutcheon plate off the shower valve and look for signs of water staining inside the wall. Those checks tell you whether you have a real problem. They don’t fix it.
Where DIY goes wrong on a CGI bathroom is the waterproofing. Replacing a pan means cutting out the bottom row of tile, pulling the old pan, re-setting a new one in a fresh mortar bed, and rebuilding the waterproofing so it laps correctly onto the wall membrane. Get the lap order wrong and water runs behind the membrane instead of in front of it. Get the mortar bed too dry and the new pan cracks within a year. This is the work we’d rather do right the first time than come fix after a well-intentioned weekend. If you’re seeing any of the signs above, call us at (559) 540-8453 and we’ll give you a written estimate. You’ll know the price before anything comes off the truck.
FAQs
A properly installed CGI bathroom remodel should last 15 to 25 years in Fresno’s climate, with the waterproofing layer being the component that determines most of that lifespan. The original CGI pan itself can last decades if it stays rigid and the gasket is maintained. Fresno’s hard water shortens fixture finish life faster than the climate shortens the structure, so we usually recommend fixtures with PVD finishes that stand up to mineral buildup better than standard chrome.
Some components can, and some can’t. A leaking drain gasket, a failed valve cartridge, or cracked grout at the pan transition can often be repaired without a full remodel, usually for a few hundred dollars. But a flexing pan, failed waterproofing behind tile, or a cracked pan flange means the pan and lower wall assembly need to come out and be rebuilt. We’ll tell you which one you have during the estimate, not after we open the wall. Call (559) 540-8453 and we’ll take a look.
Most CGI bathroom remodels we complete in Fresno take two to four weeks from demolition to final walkthrough, depending on the size of the space and whether we’re moving plumbing. A straight pan and surround swap in a standard hall bath can be done in five to seven working days. We keep a project calendar that Graham Stein updates whenever something changes, so you’ll never wonder what day the tile crew is arriving. Quiet tools during family rest hours are part of how we schedule, and we ask before moving anything in the house.
We stock the common CGI replacement parts on our trucks: drain gaskets, pan shims, threshold sweeps, and valve cartridges for the most common CGI series. Specialty pans, custom surround sizes, and specific trim finishes usually need to be ordered from our supplier, which adds three to seven days to the timeline. We’ll tell you during the written estimate exactly what’s in stock and what needs to be ordered, so there are no surprises after the crew arrives. Elmstead Remodeling Fresno is an independent remodeling contractor and not affiliated with CGI, but we work with their components every week.
