Collection: 4 Person Saunas

A 4 person sauna gives a household or small group room to stretch out, lie down, or sit together without bumping knees. Most four-seat models land around 5 by 6 to 5 by 7 feet, fit a garage, basement, or covered patio, and come in infrared, traditional, and hybrid heat. Restore Suite offers financing and possible HSA/FSA reimbursement with a Letter of Medical Necessity.

How much space a 4 person sauna needs

Plan for an interior footprint near 5 by 6 feet at a minimum, with taller cabins reaching about 75 to 80 inches in height. Add a few inches of clearance behind and beside the cabin for airflow and assembly, and confirm the unit fits through your doors in its largest panel. If you are unsure how capacity maps to room size, our sauna sizing guide walks through bench length, seating, and lay-down room so you do not overbuy or undersize.

Electrical and heat type

Heat type drives the wiring. Many 4 person infrared cabins run on a standard dedicated 120V circuit, while larger infrared and most traditional four-person rooms need 240V because the heater draws more power. Infrared units in this size typically pull 3.0 to 4.8 kW, and a traditional room this size usually wants a 6 to 8 kW heater. Have an electrician confirm the circuit before delivery. Compare heat styles across our infrared saunas and traditional saunas collections.

Who should buy a 4 person sauna

Choose four-person capacity if you have a family, host friends, want to lie flat during a session, or simply value extra elbow room. If it is usually one or two people, a smaller cabin costs less to buy and run; see our 2 person saunas, 2 person infrared saunas and 3 person infrared saunas.

What a 4 person sauna costs to buy and run

Four-person saunas generally sell from about $3,000 to $7,000, within the broader $1,500 to $9,000-plus market for home saunas, depending on heat type, wood, and features. Running cost is modest: a typical home sauna this size costs roughly $25 to $50 per month with regular use, since heaters cycle rather than run flat out. At the 2025 US average residential rate near 17 cents per kilowatt-hour reported by the US Energy Information Administration, a 4 kW infrared session of 40 minutes costs under 50 cents.
