After a disaster with a shower spider I desperately needed an alternative. When I found this works tub ring. The installation was really simple (three holes must be drilled), I worried only the correct plugs for my drywall. And that's about it. The shower curtain should have 16 loops. Then one has a really great shower. My recommendation: Shower Curtain 180 x 240 cm for mounting on a bath, proper screws and dowels, measure, drill and - showers :-).
