Over the last decade, watershape designers and builders have been pushing the limits of what can be created with water. Even in cold climates, builders are incorporating features what were thought only to be possible in regions with warmer weather, where the limitations are fewer. Building pools in cold regions requires excessive engineering and solid construction techniques to be able to withstand the yearly onslaught of snow, ice, and frost. As the temperature drops, it is an inevitable fact that most pools, spas/hot tubs, and water features go through some sort of winterization or seasonal shutdown.
