I have the Kohler Underscore bathtub (K-20201-LA-0 ) and am looking for a sliding door that will fit. I like the design of the Levity Plus door (K-702420-L-2MB). However, it requires a minimum flat of 3" and the bathtub has 2.75".

I have had mixed info from Kohler, one representative told me it would work but with an overhang. Another told me it won't work because of stability issues.

I was wondering if anyone:

1. Had recommendations for a sliding door that would work for the bathtub.

2. Is familiar with the Underscore and Levity and knows if the overhang would cause any issues (apart from cosmetic)?

Thanks!
