Take a look at Sonos.
You can use a Sonos ConnectAmp for each room with ceiling speakers. Each room will be a separate zone that you can control with the free Sonos app. Not cheap but does a lot more than just bluetooth streaming. Your phone, tablet and computer is a remote.
They also make wireless speakers. You can use them as mono or stereo or stereo plus wireless subwoofer. Can be set up for surround sound too,
Very flexible and easy to set up and use.
Accesses streaming sources, internet radio, and music files on your network.
