The new house has a shower in one of the bathrooms, enclosed by walls. In plan it looks like a square with one corner cut off, one of the two long sides of the square being open to the bathroom.
Because of the awkward shape, the current owners have custom-built a shower "tray" by tiling the base as well as the walls. There's some evidence of leakage where the grout has lifted out and the public swimming baths look doesn't really appeal to us in the first place. Subsequent repairs and attempts at regrouting have left the whole thing looking rather a mess, so we're thinking of replacing at least the base of the shower.
The first option that comes to mind is to install a quadrant-shaped acrylic shower tray with the corner where the two long sides of the base meet and the curved side towards the "cut off" corner, but I'm not yet convinced that this will be a big improvement in terms of stopping leaks because there will still be a reasonable area of horizontal tiling. A square or rectangular tray would be too small to fit into the space.
My other idea was to line the entire base and part way up the wall with the material used for wet rooms, butting up to the bottom row of tiles on the walls, or perhaps even running up behind them. The downside of this approach is that I have no experience whatsoever of using the material in question. I don't even know what it's called.
Does the second method sound viable? If so, where should I be looking for the wet-room material and what is it like to fit?
Are there any other options (short of ripping out the bathroom and starting again, which is in the five-year plan :) that I should consider so that the shower is at least pleasant enough for guests to feel that they might actually get clean in it?
