Verdict: is the Almost Heaven Salem worth it?
Yes, if you want a real Finnish-style sauna for one or two people and have room outdoors. The Salem is a compact 6 × 4 ft cedar barrel with a 6 kW electric heater and a rock tray you can throw water on — traditional convection heat, not infrared. At $4,485 list ($4,036.50 on sale on the official site in October 2026, heater included) it is the cheapest traditional sauna in our reviews. Skip it if you need room for more than two, want a wood-burning stove, or cannot run a 240 V circuit to the spot.

Traditional vs infrared: which do you want?
A traditional sauna heats the air (typically about 80–100 °C) and the stones; you control humidity with water. Infrared cabins run much cooler air (roughly 45–65 °C) and warm the body with radiant panels. Traditional heat feels more intense and is what the long-running Finnish studies measured; infrared is gentler, installs more easily indoors and suits people who dislike hot air. Neither is better for everyone — but if your reason for buying is the research, traditional is the closer match.
What the evidence actually shows
The best-known study is Laukkanen and colleagues, JAMA Internal Medicine 2015 (doi: 10.1001/jamainternmed.2014.8187). It followed 2,315 middle-aged Finnish men for about 20 years. Men who used a sauna 4–7 times a week had markedly lower rates of fatal cardiovascular disease and all-cause death than once-a-week users, and longer sessions were associated with lower risk too. Two honest caveats: it is observational, so it shows an association rather than proof that sauna causes the benefit, and it studied men using traditional Finnish saunas. It does not show that any particular product, including this one, will change your health.
The real total cost
The sticker price includes the sauna and heater, but plan for:
- Electrician: the heater must be hard-wired to a dedicated 240 V / 30 A circuit, plus a 110 V supply for lighting. Cost depends on the distance from your panel and local rates — get a quote before you order.
- Base: a level, solid surface such as a concrete pad, pavers or a deck.
- Permits: electrical work and outdoor structures are regulated locally — check with your town or HOA.
- Assembly: it arrives as a DIY kit; plan a day with a helper or pay an installer.
- Running costs: electricity for a 6 kW heater during warm-up and sessions, plus occasional stone and wood care.

Who should buy it — and who should skip
Buy it if you want authentic hot-air sauna with steam, you are one or two people, you have an outdoor spot and a reachable 240 V supply, and you would rather spend on the sauna than on a brand premium.
Skip it if you need four or more seats (look at larger barrels), want a wood-burning stove, need an indoor unit, or find high heat uncomfortable — then an infrared sauna may suit you better.
