Things i would do differently/wish i've done.
1. I took pictures of everything, all the plumbing/drains etc, but i failed to use a tape measure. There has been a few times i wish i knew exactly where everything was.
2. Larger Baja shelf/area
3. return jet near the "baja" shelf since its only on 6" of water it tends to over power, i wish it was angled toward the skimmer.
4. Separate control for skimmer/drain. Since all we get is small dirt, brushing it toward the drain would be great.
5. Extra drain on pavers, with some of the heavy rain it would be helpful. I may need to do this myself later.
6. Be a little more picky on the tile work, they did a good job over all but the 90degree cut could have been better.
