Cast Iron Clawfoot Tub weight concerns


I want to put a cast iron tub in the second floor of a 1903 Victorian. The joists are 2x10, 16oc. I think they span 16 feet but I am sistering them to span the length of the bathroom which is 5 feet. This will make for 5 2x10's spanning 5 feet.

A clawfoot weighs about 300, plus a human and water, for a total of upwards of 700 pounds. Will the joists be able to carry the load?

Kind of defeats the purpose of an advice forum, no?

My question isn't only about the load capacity of said joists, but a more nuanced interest in whether the rim upon which they will be resting might be impacted as well as surrounding structural components I may not even know about or know enough about to consider.

Check for excessive structural deflection with the weight of one or two people in place of the tub. Scale up to the tub weight for whatever deflection you measure. The scaled-up value should probably be less than 1/4".

I'm still trying to figure how to sister a 16' span down to 5', without closer bearing. Could anyone explain that to me? Be safe, GBAR

Sounds like he only sistered four of the 16' joists for a width of 5 feet.

If the span is 16', by looking at the ceiling of the room size downstairs, the bath 5' lands somewhere in that span.

To just add a sister joist next to a longer joist, you're just adding more weight.

The span has not changed any, unless you add a closer bearing point.

The good news is the old joists are a full 2"x10", real measurement. With today's joist that size, is rated at 40# live load, 10# dead load times 16' = 800# per square foot. Minus any walls, other fixtures, or adjoining room weight (dressers, beds, etc.)

Be safe, GBAR
