I have swimming pool on my back yard which is right hand side of main door, which I can not move.
What can I do to cure this problem?

You said the pool is in the back yard. Is the back door the one the family uses all the time? What you can do is to place a row of potted plants between the pool and the house. Nothing huge, just something to break up the line of sight.

I feel you. My friend has the same scenario and just wondering how to solve it. i think potted plants will make a difference. quick set pools are very flexible than pools.

Swimming pools should not have sharp corners, especially if the corner points back to the house
