We are building a pool this summer and thought we had all of our decisions made...until we saw a photo of a pool with our 2nd choice tile (PB wanted us to have a 1st and 2nd choice to help avoid any delays) and decided that we didn't like it. Off to the PB we went last Saturday, and not only picked out a new 2nd choice, but we also made a new 1st choice. While there, the office manager mentioned that they were now offering a light gray tinted plaster, as she knew that I really want a deeper blue water than we will get with the white plaster that we had planned to use. It seems that they mix black into the marcite to achieve the color. She advised that the cost was small, but would have to get a quote. She called yesterday, and although our pool is going to be small, we are subject to the minimum charge of $900 for 450sf. In my mind, I was ready to say "do it" if she came back with a cost of up to $500. The price caught me off guard, and I just can't get the idea that it's "another $1,000" out of my head. I realize in the grand scheme of things, it's not much money, but it's more than I was expecting based on our conversation. We don't want to do a pebble finish, for a variety of reasons, with cost only being a small part of the decision, even though it's considerably more expensive.
So, now for my questions. I've read a bit about white vs. gray plaster on here already, but want to see if anyone has any new opinions or recent experience and/or suggestions. I'm also curious if anyone has any input on whether or not it has a great impact on the water temperature. We are in the Houston area...so it's hot and the water gets warm as well! The pool will get full sun most of the day, with shade starting to cover half of it in the late afternoon. Any input is welcome. Our layout is being done tomorrow and we are anxious to make this decision regarding the interior finish. Thanks!
