What is in the box
- HoMedics SaunaZen: sauna tent, steamer tank, hose and a folding chair.
- SaunaBox SmartSteam Pro: steam unit with tubing, fiberglass frame, insulated cover, chair, floor mat, carrying case and towel.
- SaunaBox SmartSteam XL: the same steam unit with two chairs and a larger tent.
Size and where it goes
The SaunaZen measures about 35 x 35 x 58 inches outside, per one retailer's listing. Steam tents need a floor that can handle a little moisture, near a standard outlet. A tiled room, a basement or a garage works better than carpet. Run the session with good airflow in the room.
Running cost
One retailer lists the HoMedics steam unit at 1,000 watts. At 18.2 cents per kWh that is about $0.18 per hour. The purchase price is the number that matters.
How to choose
- Heat: if you want a hotter session, look at the listed steam temperature first. Here it ranges from 115°F to over 130°F.
- Tank size: a bigger tank means fewer refills mid-session.
- Seats: only the SmartSteam XL is built for two.
- Warranty: check what the seller offers, since one-year coverage is common at this price.
