Speaker in my toilet

I would like to have a speaker in my toilet that automatically plays music or sounds when someone enters! I use sonos speakers around the rest of the house however even their cheapest speaker is too much money for this purpose! Is there a small cheap and ideally battery powered speaker that would do the job? One of those small battery powered bluetooth speakers would be ideal but not sure if compatable through smartthings or even connected to alexa. Any suggestions?

Yup, follow this post.

This has all the info you need including speakers, connecting to smartthings and the apps/devices you have to install.

You can get a cheap android phone and use Lanouncer for android and if the phone speaker is not enough then phone jack or Bluetooth to a speaker.
