What is the best tile to use on a concrete porch?

My large screen room off the back of my house is concrete floored and needs to be tiled as painting it every season and touch ups in between get tiring and expensive and never ending. It is attached to a pool so I need a tile that will definitely be a non-slip tile if wet. Some advertise that it is non-slip but aren't always as advertised. I have small grandchildren as well as older adults that would be at risk to fall. Thankyou@!!!
