The Siri and Google Assistant integration will roll out to existing smart showers this winter and spring respectively. You'll be able to turn your shower on and off, change the temp and activate your shower's presets using all three assistants.

In addition to the new voice options, Moen's debuting a new Matte Black finish for the U by Moen Smart Shower which will be offered alongside the existing Beige option. Moen's smart showers aren't cheap -- a four-outlet version costs $2,200 and a two-outlet shower is $1,160 -- so the extra finish is a smart addition that will allow the shower to blend in with more design choices.
