I am remodeling a first floor bathroom and the concrete for my shower drops down 3 inches from floor level. What kind of prep do I need before tiling the shower?
A contractor said all I need was sand mix to make the bed and didn't need a liner. I was thinking of applying RedGuard to the walls and floor. If I RegGuard on top the sand mix bed can I tile directly over that or do I need another layer of sand mix?

I would probably still put a liner in. It doesn't hurt to have, and a liner makes sure all the water goes where you want it to go. You can use RedGuard in place of a shower pan liner, but make sure you read the product instructions on how to achieve the correct thickness. I believe it's 2 coats of product to meet the requirements for a pan liner.
You can also mortar/tile directly over RedGuard (in fact, you have to - RedGuard is not meant to be left as a finished surface).
