SpaceTime Tanks

Space Time Tanks is fantastic! I was taken floating here for the first time on a date (best date ever). One hour in the sensory deprivation chamber left me feeling more refreshed than an entire night of sleep. In a world with so much clutter and noise, it's amazing to be able to just shut it all out and decompress in this way. My recommendations: pre-floating, don't consume too much caffeine and don't shave right before (or the salt may sting), and while in the tank, I recommend wearing the earplugs they provide...to prevent getting any water trapped in your ear! Their shampoo smells fantastic, the staff are super cool and mellow. I highly recommend this experience. Everyone I have taken to this place really gets something out of the experience. After floating, you may find yourself super hungry and your skin will feel amazing!
