The outside is specifically camouflaged so as to not draw too much neighborhood attention to it. the spa across 12th street with it's huge store front spa was not the image they were going for. When renovating the interior they could have easily spruced up the outside. Besides, it's not the Jersey Shore, no need for any outside showers to rinse the feet.
I'm just glad I don't use a wheel chair, that ramp must be a bitch for anyone that needs one. I just wish the railing was a little higher, seems a little easy to fall over if you somehow trip going up.
