I have an old house, circa 1775. I had a claw foot tub downstairs. Had to take it out and replace with washer and dryer. Want to put said claw foot tub in upstairs bathroom which currently has an old decrepit stand up shower. I have two little kids who miss their tubbies! My concern is floor support. This old house has NO floor joists between first and second floor. It's just a subfloor spread across exposed beams. The Sheetrock of my first floor ceiling is screwed right to the subfloor. Subfloor is an inch of some old wood (still in good solid condition) and an inch of hardwood floor. It seems solid, however the space for the tub would be right between two of the beams. No way to straddle it across a beam. The beams have 43 inches between them. Do you think it will hold the heavy iron tub plus water plus a person???
