Welcome to TFP!
Houston is a good location to give people in the rest of the country an idea where Huntsville is. (btw, I love the rolling hills up there!.) But to people living in the many suberbs in and around Houston, you're a good ways off to try to compare pool prices. You're about an hour and a half drive from here. It sounds like a good bid compared to my area in Cypress considering the equipment you listed, dimensions, and pool features. Is the spa in the diagrams included in the cost? Are the 'Pentair color LED lights' and '250 Watt Pentair electric pool lights' you later mentioned the same thing? If not, get the LED color lights. I really like your design - good job on the shelf and benches! It looks like you're going to have a nice amount of decking, and I love the terraced levels.
Is this the bid you have narrowed down to, or the only bid you have so far? You'll get a better comparison of prices in your area with 3-4 bids, but I'm not sure how many PB's are in the Huntsville area.
I agree with Yippee - ditch the Polaris cleaner and booster pump. I love my robot cleaner. She does a fabulous job of cleaning the floor, walls, and waterline tile. For me the other benefit is that the robot is not in the water all the time. It annoys me to have that floating line in my way when swimming. I have heard of others who are like PoolingAround and prefer having their cleaner in the pool all the time. So a cleaner is another choice based on personal opinion.
Glad you convinced your wife to get a pool!!! Since you've been lurking for many years, I'm guessing you've also read TFP's method of water maintenance. When your wife sees how easy it is to have the prettiest crystal clear water (and the safest), she will LOVE having the pool!!! I never imagined it would be so easy.
When you get a chance, post pictures of your backyard where your pool will be going in! The more info you can give us, the more we can give you our opinions! (if you want them - Lol!!!)
Take care,
Suz
