The life expectancy of a stock tank pool depends on the level of maintenance that you put into it, but it typically lasts for 10 years or more with regular maintenance and repairs. Regularly testing the water and adjusting the chemical levels, using a chlorine float instead of tablets that can end up on the floor of the pool, lining the pool, cleaning the stock tank, and managing any rust immediately will help extend the life of the pool.

Because they are smaller than an average-sized swimming pool, building a plunge pool is less costly than a traditional pool. In-ground swimming pools cost about $67,000, while plunge pools cost around $20,000. You won’t have as much room to swim in, but the smaller size means you spend less on land excavation, materials, and hourly labor rates.

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.

An above-ground pool with a deck can increase your home's value by as much as 4% to 7%, but it depends on your local climate, potential buyers, and the size and condition of your pool. Some buyers see a pool as a liability instead of a luxury, especially if it's at the end of its life span. In general, it's best to add a pool and deck to your property if it will bring you enjoyment—not because it raises the value of your home.
