Almost heaven barrel 4 person or 2?

Hello,

For anyone who owns the 4 person barrel sauna from Costco, can you please share whether this has any issues getting to 180 temp? I’m in mild California climate.

I’m debating between the 2 person and 4, and my biggest concern is whether the 6kw harvia is enough for the 4 person to get to temp in a reasonable amount of time (~45m).

Unfortunately the elecrician already wired a 10gauge conduit so can’t upgrade to 8kw heater

Thank you!
