We have a 45 year old concrete pool with fiberglass walls with original pool lights that no longer work (all screws corroded and could not get the cable out of the conduit). I considered keeping the lights, but came to the conclusion that after being in the house for over 15 years we only turned them on a handful of times. I am going to cover the pool Niche with some sort of circular plastic material and will glue and screw it into the niche. I found a local guy that can make me what ever i want and was wondering if anyone has a suggestion on material and thickness of it.
Thanks in advance,
