Welcome to the Forum!

That is such a broad question that iI doubt many will chime in. It's a very subjective thing - some folks prefer a concrete pool, others a liner - some like sand filters, others won't have anything but a cartridge filter...

Perhaps we could help if you'd set up a few things you really want out of the pool and tell us how you think you'll use it - if you did this and bumped the post on Tues. night - I could probably give you some input on Wed. (my next day off)
