Hello! Right after our gunite crew left today, I went out and immediately noticed that the tanning ledge looked too shallow. It was supposed to be 15" and is 12". The project manager came right out and said this was a case of first impression for him. He is calling his manager. What are my remedies at this point? We were very specific about what depth of water we wanted and even built an extra step to achieve it (unsightly, but necessary). Thanks for your insights!
