Sensory deprivation is pretty big now, especially due to its meditative effect.
But Im not paying $90 an hour to float in a pod. IMO you need to be doing more often than is feasibly affordable at that rate.
I did see the start up one which is basically a bath with a tent.
So now im wondering, why could you not just fill your bath with epsom salts, wear blacked out goggles and ear plugs?
Outside that does anyone know where you can buy a real pod in NZ?
