Do not treat “commercial-grade” as proof by itself. Ask the manufacturer to confirm—in writing—the expected daily use, commercial warranty, electrical specification, service coverage, and parts availability for your exact location.
One documented model to compare
The Clearlight Sanctuary Professional 2 belongs on a serious two-person shortlist because the manufacturer publishes useful physical and electrical specifications. It is an official-source comparison point, not a paid recommendation or a hands-on review.

Commercial infrared sauna buyer checklist
Real throughput
Expected sessions per day, users per session, reset time, booking rules, and supervised versus unsupervised use.
Commercial warranty
Coverage must apply to the actual setting. Ask what changes for a hotel, gym, studio, or short-term rental.
Electrical plan
Confirm voltage, amperage, plug or hardwire requirements, dedicated circuit, disconnect, and local inspection.
Cleaning & ventilation
Document cleaning intervals, approved products, drying time, room ventilation, flooring, and moisture management.
Parts & service
Ask who performs service, typical response time, parts stocked domestically, and the plan for business downtime.
Installed cost
Price the unit, freight, delivery path, assembly, electrical work, flooring, ventilation, permits, and maintenance.
Infrared cabin or a complete recovery room?
A two-person infrared cabin can fit a smaller studio or private training room. Hotels, retreats, high-end rentals, and larger gyms may instead need a complete sauna-and-plunge space with changing, guest flow, sanitation, and service access planned together.
For that larger project, use our commercial sauna and cold-plunge planning guide. It compares eight Sweaty Yeti layouts for 4–12 person sauna capacity, plunge, training, and changing-room use.
