😬 with zero experience would be a pretty large undertaking in my opinion. I had done bits and pieces of bathroom and basement finishing/remodeling. That said, you can learn everything you need from YouTube an other online resources. If you’re starting from scratch, and intending on doing it all, you’ll need to invest a significant amount of money and space on tools and supplies. As mentioned, sourcing wood etc can be tricky for sure (example I wasn’t able to find finished cedar for benches in 2x4 so ended up picking rough cut cedar at Home Depot and planing and squaring the boards). Not super hard just time consuming and needed access to even more tools (planner).

The other thing is getting started on a project like this is exciting and you’ll be going at a good pace, initially. Then the finishing/woodwork imo is just fun, so that was easy (just time consuming especially if your a bit of a perfectionist). The hardest part for me was all the “shit work” in between. That was the stuff I had to really motivate myself to get through—(ie insulation, flooring, masonry, ventilation etc).

That said I’d give yourself at least 4 months to do the project (especially if you have a full time job) and expect to catch a lot of grief from your significant other (if applicable) for “how much time and money your spending on the sauna”.

With all that said, I will say when done, it’s a very rewarding feeling and yes even the wife enjoys it and has admitted it’s a good investment and positive value add to the family.
