I never heard about any kind of waiting areas though...apparently you go in, one side for male one side for female, then you hit the locker/cubbie area, then a shower station where you sit on a bucket and wash with a cloth, then hit the onsen....and I never asked but I assume the pattern goes in reverse once you're done lol
This is so cute!!! I love that idea. I know it's been recommended already but I think some actual planted bamboo would be cute. Maybe some lilies of the valley too? Just seems like a flower that could fit. I'd also say a bamboo bench or something, or a little floor lamp too so that it can be illuminated at night for nighttime dips!
