I set up my ‘multi-room’ on Tuesday, I suppose you could call it faff, or half a days work.
Under my TV I have an old knackered laptop running Spotify premium, which is controlled through my tablet/phone with the Spotimote app. Its also plugged into the TV so I can use an old wireless keyboard with trackball if I want to browse Spotify for new music, but normally I use it with no display.
The laptop is plugged into an old Hifi (soon to be replaced with an old NAD amp) which in turn is plugged into a 8 way speaker switch. For now the switch is wired to pairs of Hifi speakers in the living room and bedroom, and to some ceiling speakers in the Kitchen.
Future expansion will be a stereo input speaker in the bathroom, and eventually ceiling speakers in the dining room.
I’m amazed that turning on additional sets of speakers doesn’t affect the volume, I had assumed it would get quieter each time I turned on a set.

Love it, and as a bonus, I can use the the laptop for youtube on the TV but with the decent speakers 🙂
Cost was under £100 as I only needed to buy the switch, one set of speakers and 100m of half decent speaker wire. (I think it is 16 or 18 gauge) Also my wiring wasn’t too difficult as I’m in a bungalow so loft can be used for all rooms.
