I finished building the cedar hot tub around mid-April and here is the video: https://youtu.be/WlVN8s-Uvi8
Time to build the tub: About 2 weeks
Plumbing, electrical, misc: About 2 more weeks (mostly waiting for parts to arrive)
Cost: $4000 total—Clear, vertical grain cedar wood: $1800; Misc wood for benches: $200; Spa pack 240V Balboa: $1000; Plumbing parts, GFCI breaker, filter: $500; Misc: $500. (Not included: Electrician to install 240V service to lower deck.)
This was one of the most enjoyable projects I’ve worked on. Cedar is nice to work with, soft to cut. Though I tried to be exact with the angles and the cutting, the wood was still quite forgiving and the tub did swell up as promised. No leaks now.
Plumbing and electrical gave me a lot of anxiety because it was relatively new territory for me, but I hooked up the wires the way I thought they should go, and cemented the PVC pipes and plumbing parts according to my best guess, and when I turned it on expecting an explosion, everything worked as it should.
There’s a lot of information on the Internet about how to build a hot tub or how to hook up a spa pack, but it’s scattered and sometimes conflicting. I hope this video helps you with your project.
