O' Great Plumbing Sages:
I'm about to install a new floor in my Mom's bathroom. Removing the old sheet vinyl will be near impossible, so we are going to install new underlayment and Durastone tile; this will raise the new floor about 1/2" above the top surface of the existing cast iron toilet flange. My uncle tells me this could cause the toilet to leak (even if I use a wax ring with a flange).
Is there such a thing as a "toilet flange extender"? If so, can they be installed on top of an existing cast iron flange?
