The first time we used our shower, I was getting leaking under the glass panel on the side of the shower enclosure facing the toilet. So, I re-caulked with clear silicone tub and tile caulk on both sides of the glass panel. We also bought a squeegee which we use when done with a shower to remove the water from the glass panels. (This also helps keep the shower clean.) Finally, we also try not to step near the edges of the shower pan. So, far it has worked, but we've only used our shower a handful of times since I re-caulked. It remains to be seen if this is a long-term fix.
