Is this for salt water or fresh water?

For 4' high, you will need 4 sheets of plywood. The bottom and two long sides will all be full sheets, and you could cut another sheet to make the ends.
At 4' high there will be alot of water pressure, 1/2" ply might be strong enough, as long as you had plenty of studs spaced like 12"-16" on center. Not just at the corners. I also think you should go with the pond liner. Especially if you decide to do some plumbing, there all sorts of special bulkheads, and such, made to work with the pond liners. So all and all, I think your initial cost may more than double.

I only wish I had a basement! I’ve thought lots about having some sort of lookdown saltwater tank if I had. My thoughts were more on the lines of somehow bonding together a few circular tubs in a three sided clover shape or something, then throwing a liner inside it all to keep it water tight.
