This toilet was a spectacular pain in the ass to install. We special-ordered it in October, the first three arrived broken. With deep February came the arrival of the 4th unit. I didn’t notice that the bottom of the casting had a crown in it until after I smooshed it down on the wax ring. I thought the ring had slipped and was interfering with the seating, but no. After a trip to town for a new ring and fussing over a million graduated shims to secure it, it’s finally stable enough not to wobble, weep at the seal, or crack outright. Me I’ll worry about later. Generally I enjoy setting a toilet- it’s at once easy and oddly satisfying- but this experience may be permanent.
