Kohler Corbelle™ 1.28 GPF Water Efficient Elongated Two-Piece toilet (Seat Not Included) & Reviews

The Corbelle™'s two-piece toilet delivers powerful, clean swirl-style flushing in a sleek skirted design. Kohler's most complete flush ever, revolution 360 swirl flushing technology keeps your bowl cleaner longer than a conventional flush. Installation is easy with the DryLock™ system: the skirted trap-way installs to the floor flange and attaches to the toilet, eliminating the need to drill holes while offering the same secure installation as non-skirted toilets. This WaterSense®-labeled high-efficiency toilet brings you annual water savings.

Finish:White

Inspected toilet and everything was fine until after install and we heard leaking. Installers took out the toilet and found an area that was patched and cracked.I’m now left to work with Kohler to try to remedy the situation. Going to be a hard sell as Wayfair is obviously responsible here regardless of whether it was 30 days or 45 days past delivery.
