hot tub Support Question


I'm putting a hot tub on a separate deck that is 8'x5'6 on 4-12" round concrete pillars that are 42" deep. I have 2 sets of 2 2x12 beams with 2x10 joist &16" centers. The pillars are 7' apart and was told they should be 4' apart. Should I add some more pillars in the center? (total weight is about 1 2898lb.)

hot tub Support Question


how high above the ground will your deck be for the hot tub, and what is the weight of the hot tub with water?

The total weight you posted must have a typo in it, try it again.

As to design, the prescriptive residential deck code does not cover spas on the deck, so the design of the deck framing is usually provided either by an engineer, the manufacturer of the spa, or by an experienced deck designer. The calculations normally are submitted to the building inspector when you pull your deck permit. I do not recommend using an internet chat forum for critical design issues such as framing for a heavy structure on a raised deck that falls outside standard code, I suggest you start by talking to your building inspector to see what they think.
