I was surprised it didn’t come with the toilet seat or cover since both were in the product photos. Good otherwise.

Very nice, but man, do you have to drop some coin for a black one. FYI, theres no seat! Youll have to dish out another Benjamin for that.

Good thing I have a good plumber - chain for valve too short to allow for tight seal, base bolts had to be sawed off so caps would fit.
