Inevitable movement in the toilet and floor beneath the toilet will always cause a wax seal to leak. Heat, deep flanges, & larger flange sizes are also common issues.

The innovative, patented, waxless Sani Seal has corrected all the 100+ year old short-comings of the wax seal - in one easy to install piece.

Sani Seal will even hold the bolts straight up while you set the toilet.
