Instead of a normal shower, imagine standing up every morning inside of a storm cloud: The shower curtain bucking and bellowing in the wind; the air, hot and humid as a heavy mist envelopes you, washing away soapy suds. That's what it's like to use a Nebia, the shower system that's won over the biggest names in tech without a single "smart" feature. No sensors, no Bluetooth, no Wi-Fi, but it feels goddamn glorious.
