Help with shop sound system.

[brokersteve]

We are building a 30x56 shop with a full second story. We are on a lake, and will have a decent back deck facing the water. I enjoy my music and mainly play Spotify or iTunes. I have a lot of 6" in ceiling speakers to use. I would like to setup for separate zones. 1 for out back, which may have 4-6 speakers. 1 zone for outside the front with two speakers, 1 zone for downstairs with maybe 6-8 speakers, and one upstairs with 6-8 speakers. It would be great if I could isolate even further to only play through my upstairs office speakers or bunkhouse speakers as well. I suppose another switch on that leg would do the trick. How would be the best way to set this system up so I can stream music through one or multiple zones? I have used a tuner in the past with a manual switch to turn on individual zones. I assume they have wireless switches now. How should I best setup, arrange and wire these zones through the tuner? I think I have found some WiFi tuners that would be better than Bluetooth. I would like to be able to switch inputs, zones, etc. from my phone anywhere on the property, ideally. Any suggestions? Thanks.
