I got a house which was finished in 1895 and I am currently renovating the upstairs bathroom which up until the time I arrived used to have a heavy cast iron claw foot tub.

Anyway, I took up the old plank subfloor and the joists are exposed top and bottom, they are the usual hand cut true 2x8 used for everything in homes this old. Outwardly they looked ok but after dry fitting a new subfloor I notice two joists underneath where the tub used to be had a serious of sag in them.

I now plan to replace all the joists. Anyone familiar with the latest construction requirements for the minimum size floor joist needed to span 9.5 feet 16 inch on center?

btw the old tub is NOT going back. It was so heavy that we could not get it down stairs. I covered it with old tarp and took a 10 pound sledge and it shattered into pieces.
