Hi Dreynolds, I'm new to this forum and came here to post a question when I saw your profile. I looks like we're living parallel lives, lol I had all the same problems with my PB with upgrade pricing. I've had my share of nightmares with this project but I'm almost DONE and won't have to ever see his face anymore. His latest was he wants to give ma a bill for the bobcat to come and remove the extra dirt and roots that were removed from the dig. I just can't stand him!!!
I'm at the final step and my pool is similar to your but more narrow, I wanted to swim laps too

, mine is 10x35 with a 7x8 spa and 9x10 sunshelf. I also have 1300sq ft of ivory travertine and a dark pool finish. I went with a black glass tile for WL and spa. I'm almost there!!! I thought plaster was going in today but we are getting delayed once again, it's been raining too so..., I'm in Boca not far from you
Today's issue was he told me if I custom mix my color ( he doesn't want to do it) I'll lose the BD warranty. Well, I called sgm myself and I'm trying to find out because I now don't believe anything he says anymore. I'll try to post a picture soon when I figure out how it works.
I hope you're having a better day
Oh yeah and I wanted to add he was trying to charge me a huge premium for a darker color and said it was "more labor" so there's a premium for both the color plus the labor.
