Joe obviously put in a lot of effort to create these plans. The level of detail is very helpful. He responds quickly to questions and his replies show that he has a lot of experience doing this. The project took me way longer than expected. Building something with so few right angles is time consuming (reminded me of building out my van), but I am very happy with the final product and the plans. This thing is very well insulated and all the parts I purchased from DIY Cold Plunge are functioning well. I installed the inline heater to continue plunging through the winter. I also modified a deck box with vents to protect the chiller. If I were to start over, I think I'd go with Joe's stock tank framing plans to reduce the number of cuts, work with square corners, and protect the chiller/heater since I have the room.
