Kohler's new line of smart light-infused bathroom fixtures is called the Veil Lighted Bathroom Collection. It includes an intelligent toilet, free-standing bath, lighted mirror, and lighted three-piece vanity, as well as smart lighting accessories like a remote and motion sensor. 

The lighting accenting the fixtures synchronizes and is fully customizable. You can adjust lighting effects through the Kohler Konnect app, via voice, with motion control or with a physical remote controller. The collection works with both Google Assistant and Amazon Alexa. Prices for the fixtures range from $199 for smart accessories like a motion sensor and remote to $4,849 for the free-standing bathtub. The line is scheduled for availability in the second quarter of this year.
