Excellent option for a 14" rough in on a Kohler toilet. (If you have a model that fits this type of Mount)

Used this item to bring a Kohler Gleam toilet closer to the wall behind it. Worked like a charm.

No need to special order a 14" toilet. This adapter is easy to use and worked well.

Kohler makes quality products. Unfortunately this one was miss labeled... it was not the size listed.

Product is genuine Kohler part, but price is ridiculous for and injection molded unit. Extremely expensive for no good reason. Only purchased it because I was in a bind to install a toilet and plumbing supply did not have in stock and was 3 months out for ordering because of phony supply shortage created by, do we know?

When I order my Valiant 14in rough in toilet, they sent me a Valiant 12in rough in toilet. Ordered the, KOHLER K-5381-NA Rough-In Full Skirt Trap and Attachment System, 14-Inch, after checking with Koehler. They said it would work for the Valiant toilet. I had the Valiant toilet professionally installed using this 14in rough in. Worked great!
