The price to build a natural swimming pool depends largely on the builder. Some companies quote that a natural swimming pool is cheaper to build than a conventional swimming pool. Others quote that a natural swimming pool costs about ten percent more to build than a conventional swimming pool. Even if the natural swimming pool costs more to build, the maintenance costs of a natural swimming pool are much lower. So in the long term, a natural swimming pool is cheaper. Natural swimming pools require very little maintenance because the aquatic plants do most of the work. The only regular maintenance a natural swimming pool requires is the emptying of the filter which can fill with debris.
Natural swimming pools require less heating than conventional pools. The reason is because the regeneration area of the natural swimming pool is shallow. The shallow area of water rapidly heats in the sun and is dispersed throughout the pool by the filtration system. If more heating is desired, a solar heating system utilizing solar panels can be installed to heat the pool.
Conventional swimming pools can be converted into natural swimming pools. The costs associated with this can vary depending on the original pool and the desired outcome.
