Aircraft
After takeoff the Flight Attendant called the cockpit to inform us that there was smoke coming from the lavatory. The Captain immediately [advised ATC] and asked to return for landing. We then received an EICAS message and warning stating that we had Lav smoke; we then complied with the checklist items. We were given instruction by ATC to turn right to the airport and I executed a Visual Approach. I landed flaps 45 and brought the aircraft to a complete stop. The Flight Attendant stated she would like to evacuate and the captain gave the order to evacuate and we followed the evacuation checklist that is placarded.
After takeoff the Flight Attendant called the cockpit and informed us that there was smoke in the cabin I immediately [advised ATC] and asked to return for landing. We got an EICAS Lav smoke message shortly after the call. We came to a complete stop on the runway allowing emergency equipment enough space to approach the aircraft and did our checklist and ground evacuation.
