Subject: Need Help finding a bath tub that's less than 59" in le

This forum has been incredibly useful to me in the past but this is my first post here!
My husband and I are trying to finish our small cabin, and don't have enough room for a standard sized bath tub. I have searched quite a bit, but have not had much luck. Can anyone give us names of manufacturers that make smaller sized tubs? Any help would be greatly appreciated.

And maybe consider looking for stuff intended for RV's, you could probably find something that would work there too.
