I am estimating a small bathroom remodel in a house and it currently has a 48"x36" shower. Is there any way you can get a bathtub that is only 48x36? If so any suggestions as to where? We would still install tile surrounds for a shower, but would give them an option of having a bath for kids, as they are currently all taking showers because the house has no bathtubs. Any help would be appreciated!!
