Hey everyone, I did some searching on this but couldn't really find any direction. Just looking for a proper way to add to the B measurement of the Coombs 9800 full sneak wall pedestal. The 8" A measurement is great but need more girth in the B measurement. 24" wont cut it. I apologize if there is a tutorial for this that I am missing, but like I said, just looking for some proper directions in adding to this B measurement while keeping everything looking anatomically correct. I appreciate any help!
