Generally, you do not need to drain your pool to convert it to a saltwater system. The main exception is if you have used an antibacterial agent containing polyhexamethylene biguanide to sanitize your pool, as these sanitation products do not mix well with saltwater systems. If this is the case, you will need to start fresh. You can either drain the pool or treat the existing water with a high dose of chlorine to remove the antibacterial agent. If you choose the chlorine treatment, wait several days to allow the chlorine to work before proceeding with the conversion. If you are unsure whether this applies to your pool, consult a pool technician.

Whether a natural pool is worth it depends on several factors because they cost more than traditional pools. Many people opt for natural pools because they enjoy swimming in natural bodies of water such as lakes. Also, if you're environmentally conscious, a natural pool is going to be a much more attractive option than a traditional pool.

Moreover, for people with chemical sensitivities, a natural pool is a great solution since the water doesn’t contain chlorine.

The depth of your pool depends on its intended use, the size of your lawn, and whether you opt for an in-ground or aboveground pool. Aboveground pools tend to be between four and six feet deep while in-ground pools range anywhere from three to eight feet. Permanent installations also have the option of shallow and deep ends.
