Leaky Curbless Shower. Ideas?


I am about to work on a leaking curbless shower. It looks like it was improperly installed. The pan (under the grout) fills with water, and then overflows causing the baseboards to become slightly damp. I know the first answer is the pan was likely not installed correctly. Most possibly, the gradient isn't steep enough to allow sufficient water to drain out. Are there any other less labor intensive things that could be done in this case? I am trying to do this job as cheaply as possible. Could I build a curb right outside the glass door and directly at the lip of the pan? I would only need to remove a few tiles to do this.

Check the pitch, with "normal" tile 1/4" per foot is all that's needed. Pebbles need 3/8-1/2.

Odds are this is a capillary issue, they did not install a capillary break.

Thanks for the reply. I will check that. I can see a small portion of the pan once I removed the baseboard. It seems covered correctly by a PVC cover. From that vantage point, I can watch the water rise to the point of overflowing. It then runs, like a small river, in the channel once occupied by the baseboard - in between the tile and the bottom plate stud. It takes about 10 to 15 minutes of running the shower for the water to reach this point.

How is the water getting to the pan liner?---through the grout and/or tile.

If this is a mud pan, probably should have had a drain with weeps, if not, you need a capillary dam to prevent the water under the tile from leaving the pan.

I assume it is getting to the pan through the grout and tile. Could the drain also be leaking? It is the standing, center of the pan, style drain. The shower is built on a slab foundation house.

Who built the shower? Can you get any pics of the work in progress?

Yes, it's getting through the grout and tile.

Seeping between the tile and the drain, maybe.

If the water is on the liner, not under, I doubt a drain leak is causing this.

Take up the tile around the drain. Fix it so the pan-liner water can flow into the drain holes.

Just about the only way I know to fix something like that.

There’s my $3.50

If they put in a drain body with weeps. Have a feeling they didn't, with the liner above the pan, weeps are not be necessary. As described this is not a water in/water out system.
