You may have seen them in magazines. You might have thought - dang, that looks cool and when I need to replace my regular old stupid toilet, I'm going to do something extraordinary.
Before you do it, call me. Call me and ask, "What was it like? For 3 weeks?" and I will tell you "Thank god we had a 2nd bathroom."
SQUARE TOILETS ARE CRAP! Seriously. There is a reason toilets are round. Don't argue, don't try to be "cool" or "fashionable". Just go with the usual thing because it is "standard" for a very good reason.*
*Your ass is round! All our asses are round!
