Do you have to use the curbs on these kits? Or can I cut my floor down to make it even? We just found out my wife has ALS and we need a roll in shower.

The curb-less shower kit is called the wedi Fundo Ligno. We carry that as well. It is not available in kit form, but if you tell us which size shower pan you need, we can provide a list of additional items to complete the shower.
