The verdict
Redwood Outdoors Extra-Wide Barrel Sauna (6-Person) takes the higher score here. Solves the one real complaint about barrels. The wider diameter buys back the headroom and lets two people lie down on the upper bench.
It is also the cheaper of the two by $4,100, which makes this an unusually easy call. The case for the Sun Home Saunas Luminar Outdoor Infrared (2-Person) rests on what it does differently, not on value: The only outdoor cabin here that needs no staining, sealing or cover, ever. You pay roughly double a thermowood barrel for that, plus infrared instead of steam.
Put plainly — unless one of the Luminar Outdoor Infrared (2-Person)'s specific strengths below is the thing you are buying for, take the Extra-Wide Barrel Sauna (6-Person) and put the $4,100 toward installation, which is the line item most first-time buyers underestimate.
What each one is good at

- Noticeably better heat stratification than the narrow barrel
Compromises
- $1,200 premium over the standard 6-person barrel
- Larger volume needs a bigger heater, pushing electrical cost up

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
