- What are the dimensions of this pool? depth?
If you aren't planting a large tree in the space, 3 ft. is fine. The dimension that looks right will depend upon the proportion of overall design. Work with the space available, just give any trees you may be planting space for them to thrive.
This looks great, I would love to have something like this in my yard. The pool with the plants looks awesome. Does it take long for the plants to grow, and give privacy? http://jklandscape.com/
