Rubbermaid stock tank as duck "pond." Use a 1-1/4" male threaded adapter on the 1-1/4" threaded drain, along with a length of 1-1/4" PVC pipe and a 1-1/4" ball valve to drain.


The idea of using a stock-watering tank for a DIY hot tub project has been around for a long time, but all of the ones I’d seen were pretty unattractive. I wanted a setup that was nice-looking, easy to use and economical. My hot tub dreams came together when I discovered a wood-fired spa stove made in Japan by a company called Chofu and imported by Island Hot Tub Co. Depending on how the soaking area is customized, the setup I’ve designed can cost less than $1,000.
