On a reposition flight from ZZZ to ZZZ1 at level off the Lav Smoke warning went off while we leveled at 6;000 feet for the really short flight to ZZZ1. Captain walked back to the lav to observe a light blue haze in the lav and the last three seat rows. There was also an electrical burning smell. The First Officer was the Pilot Flying; we switched; he was fairly new and did a great job. I then instructed him to do the Lav smoke QRH; while I advised ATC and took the radios. He pulled the respective circuit breakers and completed the checklist and then got ATIS; Landing Data; and set us up for a runway change while I flew the plane direct to ZZZ1 after advising ATC. We landed and ARFF (Airport Rescue and Firefighting) got on but no smoke was observed. I attempted to call Maintenance Control and got a message that all controllers were busy and to 'Call Back Later'. We walked into the Maintenance hanger and the awesome ZZZ1 maintenance team told me they would take care of it. Unseen threat of Lav Smoke. A few navigational errors were made and trapped. It gets really busy and when you smell electrical smoke your adrenaline starts to kick in and muscle memory takes over. I'm actually surprised that we got all the checklists ran. We did a great job dividing and concurring.Not much I can do; but my question to management is what is the company doing to be proactive and predictive with some of our own airplanes? Do we have the staffing to do the best job and is our SMS system doing its thing? I'm starting to get really scared out here flying the line. There's only so much we can control; but it feels as if we are all about spin and less about running an effective risk based airline. I might be back; I take the same aircraft to ZZZ2 and back today! I just hope Maintenance Control picks up when I call.
EMB-145 Captain reported smoke in the lavatory during flight that resulted in a diversion.
