Infinity pools are also known as infinity edge pools, vanishing edge pools, negative edge, zero edge, or disappearing edge. Infinity pools are always custom-built and should be designed to highlight a view. Done right, an infinity pool gives one an illusion of a sheet of water dropping off over the edge of the property, like a waterfall, although you can't see or hear falling water.

You may not have the budget or space that Celine Dion had to work with for her Florida swimming pool, but a glance at her compound gives you an idea of what family pools are all about: fun. Like a water park theme, only on a smaller scale, with fewer people. Awe-inspiring water features, elaborate slides, caves, tunnels, boulders and a general for-all-ages appeal is what recreational pools are all about. While they are often big enough, don't expect to work in some laps, at least while children are playing and splashing in one of these mini water parks. If you like to entertain, like noise, activity, and excitement, this may be the pool of your dreams—or at least your kids' dreams.

An indoor swimming pool is pretty straightforward—it's inside, under a roof and insulated by at least three walls. Indoor pools are usually simple, geometric shapes and are built for swimming or training throughout the year, especially in cold climates. The cost for indoor heating pools is lower than outdoor pools because the pool room is insulated and it's less likely that heat will escape, as it does outside.
