Whatever you order, make certain you have the instruction manual and all the parts before you rip out your old toilet. We got ours ripped out and found we didn't have two bolts. HomePerfect required that the manufacturer had to send THEM the part then they would send us the part. I ordered it through a supplier who is mailing it overnight. Needed just bolts, had to get a $15 kit, overnight mail, $44! Also the toilet was supposed to be a standard 12 inch size and turned out to be a new design that required new holes for the bolts.
