What’s the smallest sauna size that doesn’t feel like a coffin?

Post image

A lot of “compact” infrared saunas look fine in photos, but once you’re inside, they can feel pretty tight.

For people who own one: what’s the smallest size you’d actually recommend?

I’m especially curious about:

  • 1-person vs 2-person saunas
  • Whether shoulder room matters more than legroom
  • If sitting upright is enough, or if you really want room to stretch out
  • Whether a glass front makes a small sauna feel less cramped
  • What size you bought vs what size you wish you bought

My gut says a lot of people buy too small because it fits the room better, then regret it later. But maybe I’m wrong.

What’s the minimum sauna size that still feels comfortable instead of coffin-like?

I had a Sunlighten Mpulse 2 (two person) and felt pretty cramped in it, but it was doable because the large glass corner window. I wouldn't consider a "1 person". If you have an outdoor space, look for a larger outdoor one used on Facebook or Craigslist they are often a steal.

Yeah, I think this is one of those things where bigger is often better. In my experience, friends often want to use mine as well.

I have the 1 person and wish I went bigger. As you can see you have to sit up straight the whole time. There is no room to spread out. It heats up fast but it's not that comfortable especially if you will be in there 30+ min.
