Made our material selections and signed our contract on Friday. We'll be using light walnut travertine for the decking and honey lueders limestone (very close in color to the light walnut travertine) with an eased edge for the coping. The plaster is called Crystal Sea Blue. It is the PB's line of pebble finish, similar to PebbleTec's PebbleSheen line. The base color is very close to the PebbleSheen Blue Surf, but I think the actual pebbles are lighter with fewer black pebbles. We will be using a 1x1 glass tile for the water line and spa spillover, and a two inch band on the sunshelf, steps, and benches. Here is a pic of the the tile (the sample is 1x2 but ours will be 1x1) next to a chip of the plaster. We have an updated design which adds about 120 sqft to the original design. I don't have a picture of it yet, but I'll post it when I do.
