Absolutely. I found options ranging from about $150 portable sauna tents to $7,000+ premium wood saunas. The big decision is whether you want traditional high-heat sauna, infrared, or a portable steam sauna.
Home Depot — probably the easiest place to start. They currently have dozens of indoor infrared saunas, including 1-person models around $1,200–$2,000.
Costco — a particularly good option if you're a member. Their current selection includes Dynamic infrared and Almost Heaven traditional/steam saunas, roughly $1,900–$7,500+.
Almost Heaven — worth looking at if you want a higher-quality traditional sauna. They sell both traditional and infrared models directly; their current infrared lineup starts around $6,000.
Sam's Club — currently has the Backyard Discovery Rylan 1-person around $2,000.
Amazon / major online retailers — best for inexpensive portable or entry-level units; current options can be under $600.
These are portable tent-style units, rather than the wooden sauna cabins. They're inexpensive and easy to store, but they don't give you the same experience as a traditional sauna.
What I'd recommend
If you're looking for a real at-home sauna that you'll use for years, I'd target a 1–2 person infrared wood cabin around $1,200–$2,500. There are some particularly interesting values right now: Home Depot has a Dynamic 1-person at about $1,415 and a Backyard Discovery Rylan around $1,799–$1,999.
If you tell me your budget (e.g. <$1,000, $1–2k, $2–3k, $5k+) and whether you want infrared vs. traditional sauna, I can narrow it down to the 3–5 best models to buy right now, including which ones are actually worth the money.
You can buy an at-home sauna directly from specialty dealers like Almost Heaven Saunas and Sun Valley Saunas , or through major home retailers such as Costco, The Home Depot , and Amazon.
