You can use the square edge but have the edges ”eased” so they’re not so sharp.

We have not used bull nose coping since the late 90's.

I feel it's outdated for one. Secondly, in the freeze thaw locations, moisture will follow the contour of the "nose" and land on the tile. If there any slight gaps on the tile or grout, moisture can in, freeze, and loosen the tile or even the setting bed for the coping.

A square edge allows water to travel straight down. It's a much more classic, modern look in my opinion.

We install a lot of natural stone coping, namely Indiana Limestone or Bluestone, with a squared edge. Sometimes Travertine.

After setting the material, we go back with a sander and remove the sharp edge. This makes it's more comfortable to sit on the pool's edge without scraping the back of your knees.

Sometimes we have given the edge a "pencil" edge or an "eased" edge. It's not quite a bull nose, but more rounded than an eased edge.

For your pool, I would use long slabs - 6'-8'. Not 2' stones. The longer stones have less joints and are not busy like 2' stones.

14" width also (front to back measurement) as opposed to typical 12". There's an appreciable difference in the look of a 14" width over 12".

Our minimum widths for our projects are 14" and the stones are 2" thick.

I appreciate it! That’s exactly what I was looking for!

Great. Post pics of completed project.
