Actually, that is all there is to the wall. It only goes a portion of the way around the pool due to the lay of the land. In the picture above, it does kind of look unfinished but that is just because during the removal of the pool and deck, some of the top layer got bumped around and when that picture was taken, some of the stones had not yet been put back in place. I'll look and see if I have any other pictures that show it better. As far as cost, I have no idea. It was built years ago when my first pool was put up. Each piece is a separate block. They have a kind of lip on the bottom of each piece that catches on the one underneath so they can't slide or anything. You just stack them together. No mortar or anything. Easy to put up and pretty sturdy. Go to Lowe's or Home Depot or someplace and take a look at the blocks. I bet your hubby can do it. It is just stacking them. Nothing more than that.

Just to clarify --- my pool isn't dug in. There is a walk space between my pool and the retaining wall. I'll add some pictures to this thread this weekend to show you better. Check back on this thread.
