The guy sounds like a complete cock...............I would tell him to not come back in my house!!!!.....Full Stop

What happens tomorrow when he gets a call off the police as your house has blown up and he is looking at a big stretch inside.............

As at the moment you have not paid him for the bathroom.......Tell him he has till the weekend to take his stuff back and you will get someone else in..............Thats what i would do TBH.....
