In Reply to: Supporting a spa on a high deck Posted by: Cameron Huiting on May 13, 2000 at 13:33:56:
: I have a deck attached to my house which is built on a slight hill. One end of the deck is about 12 ft above the ground. I want to reinforce it to be able to support a 7' X 7' spa. I was thinking about using three 4 X 6 beams perpendicular to the joists under the spa. Supporting each of these beams would be two 6 X 6 posts mounted on piers. Will this work safely? My other option is to build stairs from the deck to the ground and installing the spa on the ground. Thanks
Cameron,
Use doubled 2x12's. Believe it or not, they will be much stronger than 4x6 beams.
You don't say what size your joists are, but if you use 2 doubled 2x12 beams under
the spot where the spa will go, you will be well supported with as little as 2x6 joists.
(since the spa is only 7x7, the joists will only be spanning 7 feet max)
Use the 6x6 posts, and brace them with diagonals one to the other with 2x4s.
Chris
