Two Room Set...

You can use them anywhere you have a Wi-Fi signal.

Hi @Petezep.

Welcome to the Sonos community and thanks for reaching out to us.

I agree with @Airgetlam and just a little information to add, as long as you have WiFi signal on the location, you may choose whether to create a stereo pair of 2 of the same model and kind of Sonos speaker or you may use them as individual Sonos Wifi music speaker depending on your choice or preference. The functionalities and versatility of the Sonos system would totally depend on the Sonos Product you are planning to buy. Please feel free to visit our website to be able to see all available products, functionalities, limitations, and specifications of each Sonos device. 

Please let us know if you still have further questions or concerns. We are always here to help.

Thanks,
