Backyard Discovery Lennon Sauna – 2–4 vs 4–6 size dilemma

I’m planning to buy a Backyard Discovery Lennon cube sauna kit and put it in my detached double garage. The garage is heated (around 8–10°C in winter), so the sauna will be protected from the elements and should heat up faster in the winter.

It will mostly be just me using it 4–5 times per week. I live alone, though a friend might join occasionally. I’m a 5’7” female, so I’d like enough room to sit comfortably or stretch out without feeling cramped. That being said I’m only going to be in it about 20 minutes at a time anyways and don’t want to go overkill with price and size.

I keep going back and forth between the 2–4 person and the 4–6 person model.

Dimensions:

2–4 person Lennon: 69.5”W × 53.1”D × 78.3”H (interior: 66”W × 45”D × 72.2”H) 4–6 person Lennon: 69.5”W × 76.2”D × 78.3”H (interior: 66”W × 68.1”D × 72.2”H)

Both use the same 9 kW heater, but the larger unit costs about $1,000 more and obviously takes up more garage space.

Since it’ll mostly be a solo sauna, the smaller size seems logical. But I’m worried about buying the smaller one and wishing I had more space later.

For people who were choosing between sizes: • Did you go smaller and regret it, or was it perfect for mostly solo use? • If you went bigger, was the extra space worth it?

Would love to hear real-world experiences before I pull the trigger.
