Hi L.! WOW I am so envious! I would love a beach entry pool!!! :-) I have a built in pool. Just a regular diving pool that's around 20 thousand gallons. When we remodel (when we get that chance), I want to make it a beach entry. I love my diving bored. That is so much fun! I've been in a pool with pebble tec inside it and I love it. Mine is only that plain ol' plaster stuff. Just the regular design. "BORING"...LOL
I do have to let you know that a year ago, my husband and I finally decided to invest in a pool "vacuum" to help keep the pool clean. We aren't able to be out there every day to sweep and net the pool, so we got one of those and we LOVE IT! It really is worth the money! So this is one of the things I would suggest investing in to help with the maintenance of your pool. :-)
I saw on "Landscapers Design" a pool kind of like what you're describing, and OH WOW...how gorgeous it was! They had a rock waterfall and there was a slide built into it. So beautiful!
If you can afford a heater for your pool, get one. :-) They are costly. A co worker of mine had a solar powered heater, and it worked well for him, but not sure how it did in the winter months. If you're here in Arizona, and you want to swim in the winter months as well, I would invest in a non solar heater. I would love to get one myself.
If you live in the Peoria area here in Arizona, let me know. We have a great Pool Maintenance man that we use all the time to come out to fix things and advise us on stuff about our pool. We've been using him for just about five years now.
Have fun this summer! :-)
