10. Nautical Pilings
Driftwood can look quite satisfying, but if you're not close to the beach, you don't want to spend much money buying items at the mall. Instead of that, you can make the vibe of driftwood without much effort by searching and using some stiff plastic and cover them with some fancy contact paper that reflects grain.
Lash them along with some dried reeds or twine to keep them together and make them look much more genuine. The extraordinary thing about this "driftwood" is that it very well may be set anyplace around your pool house and still look great.
