I really need more of a common mans answer, not a technical load mathematics answer
so give me enough details to be comfortable but please don't make me do the math :)
well, they're roughly 13 feet
scissor truss design, 2 story colonial,
vaulted ceilings and such
near the middle of the house
so the house is split into two 13 foot halves essentially
probably, but not necessarily
the tub might be same length and depth
larger soaking tub type thing
yes, near the center load bearing wall
no, definitely pretty close together
not 26' for sure
you mean span
sorry, no I've been in there
I know they're split into two that overlap at the center load wall
each side has it's own independent 13' span floor joists
on the other side of the house there are no joists
there's already a tub there
so it would be just replacing it with larger one
and it is already near the load wall
what about the 20 people in my kitchen?
is that dangerous?
because how can people have parties??
if I do the math, that's literally like driving my suburban into the kitchen
close to 1.5 tons
So, assuming the weight were distributed evenly, it actually would hold the suburban
so....how large a tub can I fit upstairs then?
in terms of water volume weight
and of course, there's a person in the tub, so add 200
what you're telling me is....if I do the math
so if the tub is 5 x 4, e.g
20 sf x 40psf = 800lbs
why does joist position matter?
definitely 2x10 and definitely 16 oc
maybe less actually
I can't remember exactly
but I had the ceiling torn open at one point and they are definitely really close together
I ran a few wires
could barely fit my cordless drill between them
well, yes, I have
thank you very much
I have another option, but it will require some work. Either way is going to be a fair amount of work to get the numbers to check out on paper.
To add the joists, you'll have to cut the wires, pull them back and then add a junction box to reconnect everything. I know it's a pain, but we've had to do this before in residential applications.
Another option is to sister the existing joists with metal studs. This will make working around the existing wiring and plumbing much easier, but requires more engineering and detailing on my end. I can do this for an additional 40, if you're interested. Just let me know.
A couple hundred buck, tops........... if you do it yourself.
For a contractor - a few thousand.
