Building a Sauna and Plunge for Under $5,000 Total

Budget was the main constraint on this build from day one, so I went with the most affordable cabin sauna kit I could find plus a manual-fill plunge tub instead of anything with a chiller. Sharing one gravel base pad between both units instead of building two separate foundations saved a meaningful amount.

Proof that a real contrast setup doesn't require spending on the premium end of either category if you're willing to do the ice runs for the plunge side.
