You can build a plunge pool in an 8-by-8-foot space. Many plunge pools are about 8 to 12 feet wide, 2 to 24 feet long, and 4 to 8 feet deep. While these pools are smaller than your average swimming pool, you may want additional space for a deck or patio to surround the plunge pool.

Yes, pool pumps use a significant amount of electricity, making them one of the biggest energy consumers in a home. A pool pump can use up to three times as much electricity as a refrigerator. Typically, a residential pool pump consumes about 1 kilowatt-hour (kWh) for every hour it runs. Because pumps often need to run for about eight hours a day to properly filter the water, this can add up to an annual consumption of 3,000 to 5,000 kWh, which can cost between $480 and $800 per year based on average electricity rates.

The amount of electricity your pump uses depends on its size, energy efficiency, and daily run time. To lower your energy consumption, you can choose an energy-efficient or variable-speed pump, ensure it is correctly sized for your pool, and run it only for the minimum time required to keep the water clean.

If you put too much chlorine in your pool, it can make the pH level more acidic, creating a health risk. You might experience symptoms like nausea, dizziness, vomiting, skin rashes, and irritation in the eyes, nose, throat, and lungs. To lower the chlorine level, you can turn off your chlorinator or chlorine feeder, add more water to dilute the pool, or remove the cover to let sunlight naturally reduce the chlorine.

Your aboveground pool might technically be able to stand without water, but you shouldn't consider it stable. Aboveground pools need the weight of water to provide adequate stability and prevent the walls from collapsing in. Be sure to fill your pool with water as soon as possible after installation.
