Hi,

My plumber tells me it's OK to take out any one floor joist, is this
true?

The floor right now is 16" on center, span 8'6" joists 2"x8".

He's removing an iron bath and fitting a shower and the drain lands in
a different place.

If I understand right he wants to cut out about 18" from the center of
one joist and add doubled 2"x8" braces before and after to the
neighbouring joists.
I'd have expected to double up the 2 neighbours but he says this isn't
needed. Possibly as it would be a pain in the ass to do as 2 water
pipes pass thru both which I assume would have to be cut and re
sweated.

Thanks

Nick..

On that small span I don't think doubling is necessary provided the headers
are properly supported with joist hangers at each end of the 16" run and for
the joist its self. It should look like # Well like a box.

Heck one picture 1000 words:

I have one in my house over a much larger span where the commode sits,
inspected and approved 1995 construction. The only thing I would do
different from the picture is to use joist hangers on all six ends. Here
they are only used for the joist and not the headers.
