My shower (over the bath) is driving me mad. We have a dribble from under the shower door. We have one of the removeable seals on the bottom. But no matter how many times I take it off, and jam it as close as possible to the wall end there is always a tiny gap letting water out. Do any of you wonderful people have a trick to stop the water getting out? Is there a door seal design that works miracles? Is there a contraption you can add? Thanks
