The Irvine two-piece chair height toilet delivers powerful swirl-style flushing in a contemporary skirted design. The clean and minimalistic profile flows seamlessly from tank to bowl, creating one of the most unique designs on the market. 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 ReadyLock system: the skirted trapway 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.
