This is the type of stuff I have always tried to convince upper-management to do. You should always try to make something better if it's design can improve with little cost difference.

The only thing that I think was a mistake, they did not do this in 5 gallons, but 3.5. As a previous tile-setter, you learn to measure by the 5 gallon and to replace that could make a better design, but smaller size not a replacement to all.
