We tiled our bathroom. I think that you absolutely have to have a backer board. I hope that construction person checks back in but I really don't think you can tile directly on concrete. Think temp differentials, give, and IMPOSSIBLE to remove if you (or anyone else) ever wanted to redo. Don't be the one the next homeowner is banging their head about! But really good demo job! Can't wait to see it progress!
