I was shopping in Lowes tonight for a basic toilet to replace an old
one we have in a rental. The original one in the rental is 10" rough
when I measured from the flange studs to the wall. Lowes only sells
12" rough-in in stock, however the toilets they had on display I
measured just for curiousity, and most actually measured about 10"
from the flange holes to the back of the tank. So I'm just wondering
why they do this?
