3. Submerged Fiber Optic “Starfield”

Bring the night sky into your pool. Fiber optic lighting creates tiny, pinprick points of light on the pool floor that shimmer like stars in the dark water.

How to make it: This is best installed during construction or renovation. Fiber optic cables are threaded through the pool shell. A central illuminator box is housed in a dry, ventilated area nearby.

Ingredients needed: Fiber optic harness, LED illuminator box, concrete waterproof conduit, professional-grade pool epoxy.
