🤔 Good idea or a waste of time…? Video Credit: @thewilleyway They’re using spray foam on the bottom of the tub to help hold the temperature longer. You can buy tubs with build in insulation but can also opt for cast iron that holds heat better than other materials. I’ve never seen this type of foam applied to a tub so if you have experience doing this please share how it turned out, was it worth it? I think a closed cell spray foam would be crazy effective but nowhere near as cheap. 🙋‍♂️ Want
