A home sauna turns your bathroom or spare room into a quiet recovery spot. Once installed, you get a daily space to decompress that is ready whenever you need it.
The best time to buy is late winter when retailers clear out seasonal stock. Expect the installation process to take a few days once the unit arrives, so plan for some construction dust.
That 0% window is a deadline, not free money. If you have a balance remaining after 18 months, the bank will start charging interest on what you still owe.
