1. The best way to put a Google Home smart speaker in your bathroom is to wall mount it well above the splash zone.
Once you do, however, here are some of the advantages to having a Google Home device in your bathroom:

​While getting ready at the beginning or end of the day, you can: Play music, get the weather report, hear the news or listen to podcasts. 
Set toothbrush timers ("OK, Google, set a timer for two minutes"), and not just for the kiddos -- two minutes of brushing is a lot, even for grown-ups. 
Timing your shower, either with a timer or alarm (or even just asking, "Hey, Google, what time is it?") so you're not late. 
Talk to others in your household by using the Broadcast feature. Say, "OK, Google, broadcast," followed by your announcement and every speaker in your house will play the message. Replies, however, will only go to the speaker you broadcast from.

• 2. Park Google Home where you park your car
  

  For example, with a Google Home speaker in the garage you can:

  Turn off any smart bulbs or other connected smart home devices before you leave (and on when you get home).
  Find out if it's going to rain while you're out and about (so you can grab an umbrella).
  If you have a smart garage controller, close your garage with your voice.
  Find out the traffic situation and drive time before you leave by asking, "Hey, Google, how long will it take me to get to [destination]."

  3. In my home office, it's like a smart second screen

I can play music, listen to podcasts or control my smart home without switching away from what I'm doing on my computer.
With music and podcasts, I can control the volume separately from my computer, so my notifications don't deafen me (or worse, go unheard).
The screen is absolutely gorgeous as a photo frame.
I like being able to glance over to see the time and outside temperature.

4. Get Google Home outdoors

A Google Home in your foyer means a speaker right near your front porch, where you can move it during weekends, holidays, get-togethers and special events. For example:

• Listen to music or podcasts while you tend to your front garden. 
  Play quiet, relaxing music for pedestrians walking past your home.
  When lockdown orders are lifted and we can visit each others' homes again, you can welcome guests to birthday parties with birthday songs, or graduation celebrations with marches like Pomp and Circumstance, or national holidays like Memorial Day and Fourth of July get-togethers with patriotic music.
