CGI Bathroom Remodeling: The Houston Owner’s Guide
CGI bathroom remodeling in Houston typically costs between $9,000 and $28,000 installed, depending on the size of the bathroom, the extent of the work, and whether you’re replacing a failed component or doing a full tear-out. We stock and install CGI-compatible bathroom products including shower surrounds, tub surrounds, wall panels, and trim kits, and we can usually have a crew on-site within a few days of your first call. Most Houston homeowners discover a CGI component has failed in one of two ways: they notice water staining on the ceiling below the bathroom, or they spot cracking or separation at a seam in the surround itself.
If you’re reading this, you’ve probably already priced out patches, watched a few videos, and realized this is not a quick caulk job. You’re right. CGI bathroom systems fail in specific, predictable ways in Houston’s climate, and we’re going to walk you through exactly what to look for, what it costs, and when you should stop trying to fix it yourself. Elmstead Remodeling Houston is an independent remodeling contractor, not affiliated with CGI. We work with their products because we know how they hold up in Texas humidity and what it takes to replace them properly.
Which CGI Models This Applies To
CGI’s bathroom line includes acrylic and composite shower surrounds, tub surrounds, and full bath wall systems in a range of sizes and configurations. The compatibility gotcha most homeowners run into is this: CGI shower pans and wall surrounds are matched sets, and a pan from one series will not always accept the walls from another. The top flange on the pan locks into a specific channel in the wall panel, and if the two pieces are from different generations, the fit is off by a fraction of an inch. That small gap is where water gets behind the surround and rots the framing. We’ve pulled apart more than one Houston bathroom where the original installer “made it work” with a mismatched pair and a heavy bead of silicone. The fix is not more silicone. The fix is the right pan and wall kit together.
How to identify what you have: there’s a CGI label on the back of removable trim pieces and on the underside of the pan. If that label is gone, look for the drain hole configuration and the corner radius. Older CGI tub surrounds had a 3/8-inch corner radius; newer panels run 3/4-inch. Measure the width of the nailing flange too because that tells us which generation of wall panel we’re matching. For OEM versus aftermarket: CGI’s current warranty covers their own parts, and we default to OEM for anything visible. But for hidden components like drain assemblies and supply-line trim, quality aftermarket equivalents from Moen and Kohler are fully compatible and sometimes outlast the OEM by several years in Houston’s soft water.

Signs Your CGI Bathroom Remodeling Is Failing
- Water staining on the ceiling below the bathroom. This is the most common first sign and it means water is getting past the surround or the pan. In Houston, our humidity means that moisture doesn’t dry quickly, so staining can develop within weeks of a leak starting, not months.
- Soft spots in the drywall or baseboard near the shower. Water is wicking through a failed seam and saturating the wall cavity. You’ll usually see the baseboard paint bubbling before the drywall surface shows visible damage.
- Cracking at the pan-to-wall seam. CGI pans flex slightly with thermal changes, and Houston’s hot attic-driven temperature swings between air-conditioned interiors and unconditioned crawl spaces accelerate this. Once the original silicone breaks down, every shower sends water behind the wall.
- A hollow or spongy feel in the shower floor. The mortar bed under the pan has settled or never fully supported the pan from day one. CGI pans need full, even support and any void means the pan flexes with body weight, eventually failing at the drain.
- Mold smell that comes and goes. In Houston’s climate, a persistent musty odor from the bathroom usually means water has been accumulating in the wall cavity for months. By the time you can smell it, the framing will need repair.

AfterReplacement Cost & What’s Included
A CGI bathroom remodel in Houston runs $9,000 to $28,000 installed. A smaller guest bath with a tub-to-shower conversion lands on the lower end. A primary bathroom with a walk-in shower, new vanity, and floor tile will push toward the upper end. What drives the range: whether we’re replacing just the surround and pan or doing full wall and floor work, the condition of the subfloor and framing once the old unit is out, and your fixture choices from our named-brand partners like Kohler, Moen, and Grohe.
Every CGI replacement job from Elmstead Remodeling Houston starts with a written price before any work begins. That price includes demolition of the old surround, inspection and repair of any water-damaged framing, installation of the new CGI pan and wall system, trim, silicone, clean-up, and a photo of the finished job and the clean-up before the crew leaves. It also includes shoe covers and drop cloths on every visit, because we’re walking through your home and that matters. Our 365-Day Done Right Promise covers every completed project: if it’s not done right, we make it right.
DIY or Call Us?
There are honest DIY steps here. You can check the caulk lines and the tightness of your drain cover. You can look for visible cracking and feel for loose panels. What you should not do is cut into the wall or attempt to remove a CGI surround yourself. The panels are adhered to the framing, and pulling them without the right removal sequence tears the studs. That turns a $9,000 replacement into a $15,000 re-frame. There’s also the water shutoff plumbing behind the surround to redirect for the new valve, and that’s a licensed plumber’s scope in Houston.
If you’ve got a leak, the fastest way to stop the bleeding is to stop using the shower and call us. Graham Stein and the Elmstead team will assess what failed, tell you honestly what does and doesn’t need replacing, and put a written price in front of you before any work starts. You can reach us at (254) 272-5240.
FAQs
A properly installed CGI surround lasts 20 to 30 years in Houston, though the original silicone at the pan seam typically breaks down and needs replacement around the 8- to 10-year mark. The biggest lifespan variable in our climate is ventilation; bathrooms without a properly sized exhaust fan trap Houston’s humidity against the surround and the surrounding drywall, shortening everything by years. Call (254) 272-5240 if you want us to assess your current setup and tell you how much life it has left.
Yes, if the failure is limited to silicone breakdown or a loose trim piece, a repair is straightforward and costs a few hundred dollars. If the pan is flexing or the wall panels are cracked, repair is not worth it because water has already reached the framing and the fix is a full surround replacement rather than a patch. Call (254) 272-5240 and we’ll tell you honestly which situation you’re in before any work is scheduled.
A standard tub-to-shower CGI replacement takes 3 to 5 working days. A full primary bathroom remodel with tile, vanity, and floor work runs 2 to 3 weeks. We respect quiet hours for families with young children and pets, and the crew leaves drop cloths down until the last day.
We stock the common CGI-compatible parts on the truck: drain assemblies, trim kits, silicone-matched seam sealant, and the pan-to-wall fasteners that usually fail in Houston’s climate. For full surrounds and custom sizes, we order directly through our supply partners, and we handle the entire process so you never have to track down a part number. Call (254) 272-5240 for a free estimate, and we’ll have the right CGI parts matched to your bathroom before work begins.
