This is a plaster pool. Unfortunately, it is unlikely you will achieve the same effect with vinyl.

I have a cement pond that I would like to have look like this color. Is there a color I could add to a light brown to improve the looks? It currently just looks muddy. For our next home, I woul like one just like this. Is there something specific I should ask for as far as color and texture? Thanks!

How wide is the coping? 12 or 24”?
