I have a newly-installed shower that leaks like crazy. As soon as the water level exceeds the depth of the low-profile tray, I end up with water all over my bathroom floor.
Is this gap in the enclosure the culprit?:
... and if so, do I just need a generous squirt of sealant or is there a component which our builder forgot?
(I'm also looking at why our trap is draining so slowly but that's another topic).
