We had a custom shower installed that does not seem to drain correctly (The water is puddling around all the sides). Unfortunately the work was not guaranteed so we cannot get it repaired (for free at least). There do not appear to be any leaks around the basin but it having the water sitting there does not settle well.

Is there anything that can be done, short of ripping the floor tile out, to fix the problem.

Is it OK to live with the problem or are we just inviting trouble down the road.
