Rated 5.0 out of 5.0 by Great Seat Highline classic 2 piece toilet was just what I was looking for. Old toilet no longer flushed correctly and need something new and in black. This was just what I wanted. May 7, 2015
Rated 5.0 out of 5.0 by Sleek and functional This product is not only sleek and functional it is quiet when you flush it. It works perfectly in any bathroom space including small two piece bathrooms up to a full bath. We bought toliet for the color so that it matched our oak counter tops and black flooring but were pleasantly suprised by the quality and function.... No problems with this product since we intalled them. September 2, 2014
Rated 5.0 out of 5.0 by should highly recommend getting a new toilet seat with this purchase. should recommend purchasing a new elongated toilet seat at the same time. they are a different size than the one I currently have. this puts off the installation about a week and is an inconvenience. July 29, 2014
