Hot Tub Platform Build Questions
CanadianSpaTech:
Yeah that's a substantial slope. You want the load equally distributed across the entire frame work. Remember the foot well is the lowest point in the spa and will carry the most weight. I would add extra support in that area.

Thanks for that input! The builder friend came out again and I showed him your frame. We measured the slope and it actually only drops 8", so not nearly as significant as I thought, but still something to build around. We agreed that I should dig the high side (while maintaining a 1/4" - 1/2" slope for drainage), then build a frame similar to what you suggested, and use a significant amount of gravel to be the primary support. The need for extra support at the foot well explains why the frame in the photo has those center members. He thought the photo was a bit of an overbuild and that the gravel would do most of the work. What are your thoughts?
I really appreciate this input. As a first-time hot tub owner there is plenty to be worried about in this process!

I don't think it's an overbuild. What's a couple of extra 2x4's or 4x4's to ensure you don't have problems 6,8, 10, 20 years on. Think of standard deck construction using 2x8 on 16" center and the photo I provided is made of 2x4's and meant to sit on level ground but I defer to your "guy" as he is there and I'm just a guy on the interweb...lol. In the end a deck up to 2' off the ground should be able to support up to 100'/SF. Please post progress and completed project photos and perhaps help the next guy. Enjoy

My guy is a figure-it-out-as-you-go type and doesn't have any hot tub experience, so I think I'll take your advice! ;)
Good idea on taking photos and posting. I'll be sure to do that! I've become a huge convert to forums with all the DIY projects the Covid year has allowed for. I've always lurked but never posted until this year; however, I appreciate the pay-it forward ethic that keeps these things running, so taking and posting photos seems like the least I could do for your thoughtful input.

My build came out great using the suggested plan above. I'm happy to post photos and describe my process, but I can't figure out how to insert pictures. Would someone mind explaining the process?
