Discussions on Kohler here (you can do a search on themenu bar above) seem to indicate that Kohler is a design of the moment. It might be hard to find parts after awhile, or if you do, you will have trouble finding them locally and have to order them. Also, if the part is not in stock, they'll not make it a priority to get it. I ordered a shower door from them and it took 6-months to deliver - that's with the distributor calling them every couple of weeks trying to find out where it was and getting new, ignored, shipping dates. Do a search, read what others have said, and some of the pros will have their own comments, both good and bad.
