I had a very tight space to fit this particular sauna into, but with only a little squeezing, everything fit together, snapped together, hooked together, and it fits perfectly with even a little room to spare! It even slides just enough that if I have to get to the plug/GFI, I can without any trouble. It looks wonderful in the space, isn't out of place, and is aesthetically the "right fit."
I've had this for 2 weeks now, and I use it after every workout (4-5 times a week). I am so glad it's the kind of IR sauna that includes heat; sweat and warmth is an integral part of the benefit I'm after, not just the IR waves. It warms up quickly, and includes enough space inside for me to sit comfortably in several different positions in order to get various legs, shoulders, and hips near the heat/IR emitters. The stereo, while BT-enabled, isn't the highest-end device, but it plays music and helps set a relaxing mood even if it's not a hi-fi stereo (that it's really just an after-market car stereo both makes sense - those can handle high temps! - and is just a little funny to me...in a good way.
I absolutely recommend buying 2 of the ergonomic backrests. No matter how you put those in the cabin, they don't touch the emitters and they keep your body parts from hitting the emitters too; like when I sit sideways, one keeps my back off the sensitive panels and the other keeps my leg or knee from hitting the panels too. More, they keep your skin from hitting the wood slats that hold the panels in place, which themselves get *hot hot hot* to the touch.
This sauna has been, so far, worth every penny. I use it, my sons (both athletes in school) use it, my wife uses it...pretty much everyone but my cat! And he's curious about it (but I don't think kitties should use saunas). Fits tight spaces and still has enough room in the cabin that all 6-ish feet of me fits fine and comfortably for all the benefits that heat and IR can give!
