In nature, a plunge pool is created at the base of a waterfall by the erosional force of falling water.  These pools are formed by its natural source but can also be a man-made option.  These pools are commonly found in gardens and are smaller in diameter when compared to the pool you’re used to seeing.

These pools are built with the same specifications and codes as a regular pool, but unlike a regular swimming pool, it isn’t designed for recreational use or exercise.  Rather, it’s more for lounging around to keep cool or enjoy a glass of wine.

A plunge pool will often be recommended if you have limited space or you don’t want your pool taking up the entire backyard.  This miniature pool, while often confused with a kiddie pool, really isn’t.  It will still function as a regular pool, using the same components, and can look just as great if done right.

How much does a plunge pool cost?

Plunge pool overview

Plunge pools, on average, will use up to 80 percent less water when compared to the traditional pools found in a backyard.  The same can be said with the variable speed pump as it will have less water to pump, effectively using 80 percent less in energy consumption.  While small, they still function like a pool and will have a pool pump, filters, seats, stairs and/or ladders.

A plunge pool can come in a variety of shapes, sizes and styles, and similar to a hot tub, it can also include seats, jets, small/large water features and so much more.  While most contractors will have designs you can choose from, you can create your own “vision” as well.  If you can think of it or even see a picture of a pool online, then it can be built if you find the right professional.

What are the extra costs?

The prices mentioned above will only include the costs of the pool and will not include the surroundings once the pool is complete.  Landscaping, patio furniture and even a concrete patio all need to be factored in, and the costs can greatly depend on what you want to do once the pool has been installed.

Adding premium add-ons, such as a water feature, can increase the costs, depending on what you’re looking to add.  Some even opt to connect a hot tub to the pool.

A plunge pool can be heated, and depending on the size of the pool and where you live, installing a pool heater will depend on the option you choose.  Some choose to have it heated by gas, whereas others install solar panels. However, due to its size, it can cost up to 80 percent less than that of a conventional pool, saving you a quite a bit of money.

Since it functions as a regular pool, you need to factor in the weekly maintenance such as adding chlorine.  Hiring a professional can cost around $80 per month, but if you were to do it on your own, it could be half this amount

Tips to know:

A plunge pool, while it takes up less space, can get cramped when two or more people are mingling around.  If you plan on having parties or plan on having more than two in the pool at once, you may want to consider a larger size.

If you plan on laps, it can be done; however, it will be much shorter than the regulation rates.  A diving board will not be an option.
