Hi, I have recently (kind of) made a wash out booth. I have been at uni for 3 years and I am missing the resources! As I'm using A3 screens I made a fairly small temporary wash out booth by using an under bed plastic box and a plastic planter from WILKO. These slotted together perfectly with the under bed storage slotting inside the planter. It sits in at an angle which directs the water flow into the planter so I can empty this later. I could potentially drill holes into the bottom of the storage box so that it drains more efficiently.
I hope this gives you an idea on how to do something similar your self, I also watched a youtube video on how to make a washout booth which attached to a drainage system which looked much better than my makeshift one.
