Toilet on slab?
Posted by Jeff on November 20, 2001 at 17:38:13:
I'm adding a second bathroom on the ground floor of my house. The bath was roughed in
by the original builder (mid 70's) yet never completed.

The toilet flange is not flush with the concrete floor but instead sits about 1/2" below the
level of the floor. Adding to this gap, I was hoping to put an underlayment on top of the
concrete as well.

My question is ...

Is it possible / advisable to add a vertical extension to a closet bend? Or do I need to bust
up the concrete and raise the entire closet bent upward?

My instinct is to do the latter but I'm wondering what's standard practice.
