While Goop's recommendation was actually to purchase a $16,500 floating tub, the idea of being trapped in a pitch-black pod while completely submerged in water sounds like a special kind of hell for me. I decided on the next best thing: a floatation tank at Brooklyn's Lift with higher ceilings and a little more legroom.
It was still dark and terrifying at first, but after 20 minutes (of the one-hour session), I nearly fell asleep from relaxation. Would I say the 1000 pounds of Epsom salt leave my hair and skin silky soft? Not really, but it was nice as hell giving my feet (and mind) a break for a fraction of the day.
