Thank you for your question on the Delta Laurel 60" x 32" Bathtub Wall Set and I am happy to help you today. Unfortunately, we do not offer a trim kit for this model and cannot recommend cutting this unit down as modifying the wall surround will void the warranty for the surround. In order to install this unit properly, the walls and sub-floor must be solid, plumb, and square.
Since the tub is not currently level, we would recommend removing the tub and setting it into a thin set mortar bed, then to install the walls to avoid any damage that may occur from installing the wall on the non-level tub.
I hope this information is helpful and please feel free to email or give us a call at 800-355-2721 if we can help with absolutely anything further!
