Going to set tub on mortar bed. Looked around on board and decided to use the Quickrete Sand/Topping Mix as suggested. Will use the pile method.

The question I have is how much should I mix up for a 60" x 30" tub? Can I mix in a 5 gal bucket by hand? I've only ever mixed cement in a wheelbarrow, and don't really want to drag that into the bathroom

Thanks for the help?
