I recently installed an Eleganza Shower Base and Wall Set in an upstairs bathroom. There was a leak at the drain. Subsequently I discovered there was a missing joist under the shower base subfloor resulting in a span of approximately 15-16 inches of unsupported subfloor, other than the 1/4" underlay on top of the subfloor. The drain was found to be loose, despite my securing it using hammer and screwdriver. The base was attached to wall studs with roofing nails, as per instructions. The shower drain was typical 2" ABS low profile. The weights of the homeowners and son are between 130-260 lbs. Could the levering effect loosen the drain to cause the leak?
