We LOVE this pool. The 10x30 is the perfect size. It fits on our patio so we can keep an eye on them from the living room and it's shallow enough that our 4 year old can easily stand in it even when full. We haven't gotten a ladder for it yet. Honestly having this pool is the only thing that keeps summers bearable. It's the only reason the kids will go outside when it's over 100 every day. They spend literal hours in it every day. We have a large sand filter that works great with it.
