Floor Load questions

I have a floor framed with double 2x12s spaced 16" o.c. with a 3/4" TG plywood deck nailed and glued. Joist span is 14'. Will this setup support 50 lbs per square foot load?

I don't know what species

of material you are using but a SYP 2 x 12 #2 will span about 18' @16" o/c. I think the double 2 x 12 is over kill.

What about to support a large whirlpool tub full of water?

not a problem

water in a tub is a temporary or live load. This should be covered in 40 psf LL in your design.

even if your tub exceeds this design load wood is great at carrying larger loads for a short amount of time

You've got like a L/1200 floor there, don't see you ever having any problems, even if you put down marble tile & a hot tub full of water on top of it!

Yep, that's a serious floor. 2x10s are usually spanning 15 ft 10 in, so to use 2x12s doubled is a solid floor.


2x8s are good to about 12 ft 10 in or so.

Depending on code, a 2x12 is good for 17' 10" or 19' 11".


If the subflooring is glued and nailed, it will most likely feel like a slab.
