The flange (?) underneath the toilet I removed (photo attached) doesn't look anything like anything I could find in current or archived posts. I'm not even sure it's a proper flange or flange extension -- there are no slots for bolts and the existing bolts fit into small notches in the outer edge and are locked in place by cement that underlies the tile flooring. The tile was cut out around the flange -- the surface of the tile is 1/2 inch above the flange. The previous toilet was held down by a super-thick wax ring and lots of very good caulk. I'm hesitant to install my new Toto Drake the same way, but I don't know if I can even find a proper extension or whatever it is that I need to do the job correctly. Should I abandon my ambition of doing this job myself and call a plumber to modify or replace the flange and install my toilet? (Everything had been going so well...!)
Thanks in advance for any advice!
