Shower Leaking Where the Door Meets the Corner Panel
When a door closes against a panel at a 90° corner, the seal on that panel edge is what keeps water in. When it wears out or is missing, water sprays right through.
The fix
- Swing door closing against a 90° panel: a strike seal on the panel edge, like CRL P090SJ for 3/8" glass. Its vinyl insert gives the door something soft to close against.
- Fin-style corner seal: a clear U with a 90° fin, like CRL PC1090 (3/8"), also used on some sliding systems.
Check the bottom corner too
Water often escapes at the very bottom corner, past the end of the bottom seal. Make sure the bottom seal like CRL P990WS runs the full width of the door, and that the base of the fixed panel is sealed with silicone.
