I like the design of the "craigslist" washer pits. The closest thing to "real" washers pitched on dirt. If the pits were to get a lot of use, I would use metal pipe, 3 1/2" OD. I would also make the a little shallower so that you wouldn't have to carry around so much dirt.
I have two 6" lengths of 3 1/2" OD metal pipe pieces. When we go camping or to a party, I just drive the pieces in the ground 21' apart and dig the dirt out of the holes. Pretty fast and simple washer "court".

The top of the board with the hole is a seperate piece and sits on the bottom frame.
