Frequently Asked Questions

Q: How much should I spend on a sauna?

A: Budget $3,000-6,000 for a quality barrel sauna with heater. Under $2,000 usually means compromises on durability or features. Over $8,000 gets you premium/commercial-grade equipment.

Q: What features matter most?

A: Focus on: (1) Wood quality and thickness, (2) Heater size for your space, (3) Construction/assembly quality, (4) Warranty.

A: Consider: (1) How many people will use it simultaneously, (2) Available space, (3) Your body size. When in doubt, size up - you can't make a small unit bigger.
