Nice set-up Clean heart. Along the line of your thinking with the tote. May I suggest a plastic mortar pan? You can get them at any box hardware store for half the price of the totes. A tote the size you have is about 12-15 bucks. The mortar pans are thicker in materials, the height is less (making it easier to get in and out) more durable IMO and doubles as a sink or clothes washer tub if need be. From the looks of it, you could incorporate the mortar pan in the system you have. <br><br>You can find the mortar pans where the concrete bags are in the hardware store. I bought mine for less than $10. They have two sizes, I opted for the smaller.
