Oasis Float Spa, Seattle

Each of the six private rooms at Oasis Float Spa encompasses a changing area and shower stocked with robes and towels, as well as the main attraction: a modern float pod.

Full of thrice-filtered, purified saltwater, the pool buoys the client's body, letting them slip into a meditative state of relaxation. Helping that process along, the float pod has a hinged lid that closes during the session. While the lid can create an environment where light, sound, and other stimuli no longer burden the senses, it also features optional pinhead-sized lights that, once switched on, twinkle overhead like stars.
