I don't do that many, but I am looking into using the ready to go fountain basins over liners for future installs. The ones I have done in the past are not that big. A 40-48" basin would work nicely. And honestly a 36" would probably work. But since I haven't seen them in person, I don't want to spend hundreds on something that turns out to be a flimsy piece of crap...plus shipping. If you have any recommendations on ones that you have used, please post it.
