The Cimarron skirted toilet bowl utilizes KOHLERs patented new ReadyLock™ installation system for easier, more intuitive installation. The skirted trapway installs to the floor flange and attaches to the toilet, eliminating the need to drill holes for a standard 12" rough in while offering the same secure installation as non-skirted toilets. Pair this bowl with the K-31615 or K-31615-RA tank for a complete Cimarron skirted toilet.
