What each one is good at
Redwood Outdoors Barrel Outdoor Sauna (6-Person)
Strengths
- Thermowood resists rot and warping far better than untreated cedar
- Wood-fired option means no 240V circuit and no electrician bill
- Assembles in 4–6 hours with two people and no special tools
Compromises
- Barrel shape wastes headroom at the edges of the benches
- Heater is a separate line item on most configurations
- Needs a level pad; the barrel cradles concentrate load on two points
Sun Home Saunas Luminar Outdoor Infrared (2-Person)
Strengths
- Aluminum exterior is genuinely maintenance-free outdoors
- Full-spectrum infrared heats occupants in 10–15 minutes, not 45
- Optional integrated red light panel consolidates two devices
Compromises
- Infrared cannot produce löyly — no steam, no water on rocks
- Roughly 2x the price of a comparable thermowood traditional sauna
- 2-person cabin is genuinely 2 people, not 2 plus a guest
