Plunge pool designs are the ultimate in backyard upgrades. Plunge pool designs can be popular add-ons to gardens or backyards. They have been shown to be a highly beneficial form of sustainable landscape architecture as they are much less expensive to heat, cover, and care for than traditional swimming pools. A plunge pool is often incorporated into an existing landscape design as an in-ground basin, either with or without a man-made waterfall. The majority of man-made plunge pool designs are built under the same guidelines as home swimming pools. These rules ensure that building codes and sanitation requirements are met effectively. They also guarantee that safety precautions are in place for the secure utilization of the plunge pool.
