Sauna for Hotels and Spas: A Guide for Hospitality Operators

Sauna for Hotels and Spas: A Guide for Hospitality Operators

Wellness amenities have gone from nice-to-have to expected. Guests actively search for hotels and spas with sauna facilities, and properties without them lose bookings to competitors who offer them. The good news for operators: saunas are relatively inexpensive to install and maintain compared to other amenities, and they deliver strong returns through higher room rates, increased spa revenue, and better guest satisfaction scores.

This guide covers what hospitality operators need to know about adding a sauna to their property.

Why Guests Expect Saunas

Wellness tourism is one of the fastest-growing segments of the hospitality industry. Guests increasingly prioritize health and recovery experiences during travel. A sauna offers:

• A premium experience. Sauna access elevates the perceived quality of a property. It's a tangible amenity guests can see, touch, and use - unlike abstract claims about "luxury."
• Longer stays. Guests who use wellness amenities tend to stay longer and spend more on-property.
• Higher review scores. Properties with wellness facilities consistently score higher on review platforms. Sauna is frequently mentioned positively in guest reviews.
• A reason to return. A great sauna experience creates emotional loyalty that drives repeat bookings.

Types of Sauna for Commercial Hospitality

Traditional Finnish Sauna

The gold standard for hotels and spas. High heat (170-195F), the option for steam (loyly), and a universally recognized format. This is what most guests picture when they think "sauna." The higher operating temperature delivers the most impactful experience and works for the widest range of guest preferences.

Infrared Sauna

A good complement to a traditional sauna, not a replacement. Lower temperatures (120-150F) appeal to guests who find traditional saunas too intense. Infrared saunas are also more compact, heat faster, and can be offered as private-use rooms for premium pricing.

Steam Room

High humidity, lower temperature (110-120F). A different experience that complements dry saunas. Requires more extensive waterproofing and drainage but rounds out a full spa offering. Many properties offer both dry sauna and steam room.

Sizing for Commercial Use

Commercial sizing is driven by expected concurrent users during peak periods:

Plan for peak occupancy. An undersized sauna during busy periods creates guest frustration and negative reviews. It's better to oversize slightly than to have guests waiting in line.

Installation Requirements

Electrical

Commercial saunas require substantial electrical infrastructure. A large 10+ person sauna may need a 12-18 kW heater drawing 50-75 amps at 240V. Multiple saunas or a sauna-plus-steam setup can require significant panel capacity. Engage an electrical engineer early in the planning process.

Ventilation

Commercial installations need robust ventilation to manage heat and moisture load in the surrounding areas. This includes dedicated HVAC for the sauna area, exhaust systems for the sauna room, and adequate fresh air supply. Consult with an HVAC engineer who has spa or wellness facility experience.

Drainage

Floor drains in and around the sauna are essential for commercial use. Water from cleaning, steam, and guest traffic needs to exit efficiently. Floors should slope toward drains at 1/4 inch per foot minimum.

Building Codes

Commercial sauna installations are subject to local building codes, health department regulations, and fire codes. Requirements vary by jurisdiction but commonly include:

• Emergency shut-off accessible from outside the sauna
• Maximum temperature limiters
• Timer controls that prevent unattended operation
• Adequate egress (exit door dimensions and swing direction)
• Non-combustible materials within specified clearances
• Health department approval for public-use facilities

Guest Experience Design

The Journey

Great spa design creates a journey, not just a room with heat. Consider the full guest experience:

1. Changing area: Clean, well-appointed, with robes and towels provided
2. Pre-sauna shower: Required for hygiene. Post clear signage.
3. Sauna session: The main event. Proper lighting, comfortable benches, quality materials.
4. Cool-down area: A cold plunge, cold shower, or cooling lounge adjacent to the sauna. The transition between hot and cold is a highlight of the experience.
5. Relaxation lounge: Comfortable seating, water service, quiet atmosphere. Where guests decompress after their session.

Pairing with Cold Plunge

A cold plunge next to the sauna creates a contrast therapy experience that significantly elevates the guest experience. This combination is increasingly expected at quality spas and is a major differentiator at the hotel level. The hot-cold combination is more memorable and impactful than either alone.

Ambiance

• Warm, indirect lighting (no harsh fluorescents)
• Quality wood that looks and smells premium (cedar is the standard)
• Tempered glass elements for a modern, open feel
• Subtle scent options (eucalyptus or birch)
• Minimal signage - clean and uncluttered

Operations and Maintenance

• Cleaning schedule: Full bench wipe-down between each usage period. Deep cleaning daily. Monthly inspection of heater, rocks, and ventilation.
• Towel and robe service: Provide clean towels for each guest. Budget for high-volume laundry.
• Monitoring: Staff should check sauna temperature and condition multiple times daily. Automated temperature monitoring systems are available for larger installations.
• Rock replacement: Sauna rocks degrade with repeated heating cycles. Inspect quarterly and replace annually or as needed.
• Guest guidelines: Clear, tasteful signage covering time limits, hydration, and when to exit. Provide guidelines in multiple languages for international properties.

ROI for Hotel and Spa Operators

• Room rate premium: Properties with wellness amenities can command $20-50+ higher ADR (average daily rate)
• Spa revenue: Sauna access as an add-on service at $25-50 per visit for non-spa guests
• Package bundling: Include sauna access in wellness packages at premium pricing
• Occupancy lift: Wellness amenities improve occupancy by attracting a growing segment of health-conscious travelers
