Going to take a dip in a pool can be a completely different experience when you keep it natural.  Check out this design and see if you think it's something you would be down for.

Keeping cool this summer has been pretty easy so far. Really no days so far that were much over 95. For this area that seems pretty mild. If you did want to take a dip and cool off, what about doing in the natural. Now don't leave your trunks at home, this pool is natural because it's all about plants an animals making it sustainable.

Not only is it eco-friendly it's better for your skin and body as a whole. So as long as you don't mind swimming with tadpoles up your nose, this might just be something for you. I really don't see how jumping into a pool with wood walls submerged just out of sight would be safe though.
