We just finished our install 2wks ago so here's my $0.02 regarding pool size. Get the largest pool you can afford that is scale appropriate for the property. We looked at going bigger but for our lot, the pool would've overwhelmed the space. I wanted to make sure we had room for adequate decking around the pool to walk around it and easily avoid the deck chairs. I also wanted to make sure that the pool wasn't pressed up against the privacy fence and the house out of necessity. There's a balance there that only you can determine. We were concerned that 36' wasn't quite long enough so we used a garden hose to layout the dimensions of the pool on our lawn. It seemed small but our neighbors had a 32' pool and quite honestly we thought that was large enough.
After the hole is dug the pool immediately looks bigger! I promise! 36' is a pretty good distance. Its not like you push off one side, do 3-4 swim strokes and glide into the far side. IMO, most non-pool people look at a 36' pool and go "Oooh, now that's a big pool!"
With respect to pool depth. A few points:
(Note - I've got 2 kids ages 9 & 7. The youngest is about 4'2" give or take. I'm 6'2" and my wife is 5'7")
- Many folks with young kids build a pool and go for the 3' shallow end. I take the view that kids don't stay short for long, so we built our shallow end 4' deep. I didn't realize this at the time but that measurement is taken from the midway point of the skimmer box. So it's probably closer to 3.75'. My daughter can easily stand and have the water level at the top of her shoulders. She's only gonna get taller.
- As a taller guy with kids that will presumably grow tall as well, I've never been a fan of the shallow end of pools. It's awkward kneeling/squatting down to get the water to a comfortable level. Personally it's not much fun hanging out in water that barely reaches your navel.
- If I had it to do all over and wanted a "play" or "sports" pool I would've gone 5.5', 7' middle, 4.5'.
- I didn't want a diving pool but we did want unlimited cannonball ability so our deep end is 7'. The kids can cannonball and not rebound off the bottom. I can tread water without touching or artificially pulling up my legs. When the kids
dive for toys they have to actually make an effort. No picking up toys with their toes. They'll probably grow gills by the end of this first summer.
- The 40' option was an additional $3k for us. If I had a bigger yard I'd like to think I would've gone for it. I don't know if anyone wishes they had a smaller pool but I know a few that wish there's was slightly larger.
