How we build a shower that stays dry
Almost every leaking shower we open in Naperville failed the same way, and the tile was never the cause. Water found a seam behind the wall, then spent a few quiet years soaking framing while the surface still looked fine. In the older homes near the historic district we find tile set right on drywall. In the newer subdivisions on the south side we pull out builder grade pans with a thin liner and a drain that nobody sealed. The early signs are easy to miss. A grout line goes dark in one corner, a bead of caulk keeps splitting, and the ceiling under a second floor bath picks up a faint ring.
So we work from the back forward. The old shower comes out to the studs, and any wood the water reached gets cut out and replaced before we build. The base goes in sloped to the drain, the walls get board made for wet areas, and every corner, seam, and fastener is sealed into one layer. We follow the membrane maker's method to the letter, since ANSI A118.10 is the standard the material is tested against. Then the pan gets a flood test. Water sits in it overnight and we read the mark in the morning. Only after that does a tile go on the wall.
- Waterproofing goes in as one connected layer, from the drain flange to the top of the wall.
- We flood test the pan overnight, so a leak shows up on our watch and not yours.
- The base gets a real slope, so water leaves instead of pooling along the curb.
- We map the layout first, so full tiles land at eye level and cuts fall in the corners.
- One crew runs demo, prep, tile, grout, and cleanup, so the job keeps moving every day.
Scope drives the schedule far more than square footage does. A tub surround in a Naperville ranch is usually a few days of work with drying time between steps. A shower with no curb, a bench, a niche, and a linear drain runs longer, because the base, the membrane, and the flood test each own a day. We will not rush a cure to hit a date on a calendar. Grout goes in once the mortar has set, and the glass goes last so nobody drills through fresh work. You get the real timeline up front, and a call from us the same day if something behind the wall changes it.
If your shower is leaking, or the tile has looked tired since the day you moved in, call us and tell us what you see. We will ask a few questions, walk the bathroom with you, and hand you a plain scope of the work. We are in Naperville every week, plus Lisle, Wheaton, Warrenville, Aurora, and Bolingbrook.
