Using old sewing machine as a table is nothing original:) I've seen this idea already many times in pubs & clubs, I have also my own table in a bedroom. But when I was arranging a bathroom I came up idea of using sewing maching elements there, and to be honest I haven't seen such solution ever before. One part of sewing machine is sustaining a top with a bathroom sink. The other part is used as a shelf. I think it's really nice and original:)
Have a nice day!
