If I remember correctly they are 27 x 19.75 x 6

When you build the top for the tub on your rack the measurement would be 28" x 19 7/8".

Trust me when I say that you want these SNUG!

In fact, if you're building more than one you should buy a miter saw to cut everything perfectly. You will be happy that you did.
