    Hi guys, just looking to double check my deck subframe, I’m planning to put a hot tub on it.

    Image attached.

    Screen Shot 2018-06-13 at 15.30.59.png

    The whole thing is constructed from 50x150mm treated timber and about 100mm off the ground.

    The red lines are the bearers 50mm x 150mm timbers spaced 1.6m apart resting on uprights (on concrete pads) space 1.3m apart

    The blue lines are the joists 50mm x 150mm on 400mm centres with a 1.3m span.

    Blue lines are connected to red with joist hangers.

    The top and bottom bearers (red lines) are against a wall so could also be ledger boards, would this be better?

    I'd add a red line incase you get a few fitties in the tub all at once :)

    Ha thanks Ian! So the spans of the joists would be reduced to around 1m instead of 1.3m

    Yes, it might be overkill with 6x2's but after I did mine I was gutted with a bit of spring in it and wished I'd have put more support under it.

    Yeah it makes sense, never know how heavy the hot tub could be!

    Do you think I should use the ledger boards on the far ends instead of posts?

    I would use posts and keep the walls clear.

    Have you got the capacity of your hot tub, amazing what they can weigh.

    1 cubic meter of water weighs a tonne and they'll be at least a couple in there!.

    Hot tub is 1.6x1.6m so the water weight will be about 2.5 tonnes plus the actual tub, so approaching 3 tonnes :eek:

    Plus the aforementioned fitties/fatties!

    That's also why I was considering placing the whole frame on the ground rather than using posts as it is a ground deck, I actually have to dig out the ground to use posts.
