Hi all. I'm remodeliing the bathrooom of a home constructed in the early 1960s and would like to install a 60" cast iron tub (Kohler Villager) in a space that seems to be just barely 60". This room appears to have been redone at least once as the current tub is fiberglass and the sub-floor (seen from underneath) clearly has been cut/patched. Anyway, the room is barely 60" wide, tubs are 60" and I'm hunting for the insight of pros to fit a tub into this spot. Any help is appreciated.
