Sauna and Cold Plunge Capacity Sizing for Hospitality

🔥 Sauna Seating Guidelines

Ideal Ratio: 1 sauna seat per 3–5 guests

• Minimum: 1 seat per 5 guests (if use is staggered or not central to the experience)

• Optimal: 1 seat per 3 guests (for premium/wellness-centered operations)

Example:

• 15 guests → 3–5 sauna seats

• 30 guests → 6–10 sauna seats

Factors Affecting Sauna Sizing:

• Turnover rate (e.g. 15–20 min typical stay per guest)

• Group behavior (do they come in couples? solo?)

• Luxury level (premium guests may expect less crowding)

• Operating hours (more hours = more staggered use possible)

❄️ Cold Plunge Guidelines

Cold plunge turnover is typically faster than sauna use. Most guests spend 30 seconds to 3 minutes in a plunge. A single plunge can accommodate 1-2 people and can be cycled every 1-5 minutes. Additional units are primarily for shared cold plunging experiences.
