If I could go back and do this whole process again I would have bought a house that already had a pool..lol
If you dont like that beautiful tile you would have HATED the 1970s puke pink colored tile on the house that had a pool already. seriously tho, a filled pool with a full patio just looks good. Its why you never 'questioned anything at any of your friends houses.' You just sat back and admired the overall beauty. Now you are conciously scrutinizing the nitty gritty of your own build. After the fact you'll hardly notice at any given moment. Also, lots of folks end up hating what they have down the road and others end up loving something that they didn't at first. There is no promise you will continue to like/dislike what you have. You could spend all that money to change it and still end up unhappy later.
