Are you thinking about adding a pool to your yard? If so, you likely know how confusing it can get with all the different options to choose from. What type of swimming pool should you choose? Should you get an in-ground or above-ground pool? Salt or chlorine? Fiberglass or concrete?

With so many different variables, doing some research and planning is a must. This is especially true if you want to save money on your pool.

To help you with that, here is a complete guide with the pros and cons of different pool designs, sanitation options, and materials. This will help you figure out which type of pool you should choose.

By the end, you’ll be ready to take the next step toward installing your dream pool.

Pool designs

First, let’s look at the different types of pool designs you can choose from. The best option for you will depend on your budget and the primary reasons you want a pool.

In-ground recreational pool

A recreational pool is the traditional pool type for backyards. The average cost of installation is $44,535, according to Home Advisor. These types of pools come in many shapes, from rectangular to free form to kidney-shaped, and beyond.

You can figure a base cost of about $50 per square foot for your pool design. The width and length typically range from 10′ by 20′ to 20′ by 40′, while the depth ranges from 3′ to 6′. In other words, there will be plenty of room for multiple people to swim and could be great for exercise as well.

Above-ground pool

This pool type can save you on the initial investment and maintenance, as it is installed above the ground instead of in the ground. According to Home Advisor, the average installation cost is just $1,653.

You purchase the pool and, typically, assemble it yourself. For accessibility, a ladder can be added or a deck can be built around the pool.

Lap pool

Lap pools are built specifically for exercise. They are usually at least 45′ long, 8′ wide, and 3 1/2′ deep. This allows enough space to comfortably swim laps without hitting the sides or the bottom.

According to Home Advisor’s figures, the cost would average around $63,000. So, lap pools aren’t necessarily a route to take to cut costs. However, they can be great if your primary goal is to get exercise.

Plunge pool

A plunge pool is a small, shallow, in-ground pool meant for cooling off, wading, and lounging. The typical size ranges from 5′ by 10′ to 10′ by 15′, and the depth is usually around 3.5′.

According to figures provided by Home Advisor, installing a plunge pool will cost around $17,500, on average. You may want to go this route if you are limited on space (or have a limited budget) and just want a pool you can dip into to cool off or relax.

Infinity edge pool

We’ve all seen and love this kind of pool. Infinity edge pools have one edge without a wall, where the water pours over into a catching basin. This creates the effect that the pool may go on forever.

This feature can be combined with any other type of pool and will add a 20% increase to your pool cost, according to Reef Tropical.

Natural pool

A natural swimming pool (NSP) uses biological processes to filter the water and requires no other sanitation system. These pools are split up into two parts: the swimming area and the regeneration area.

While the swimming pool can look like any other type of swimming pool, the regeneration area is where it differs. Water will flow through the area which contains specific filtration substrate and flora. The plants then compete for the nutrients that would typically feed algae, effectively cleaning the water.

Average estimated cost? According to Business Insider, it can range from $90,000 to $135,000 for installation.

Sanitation options

Once you’ve found a pool design you like, you’ll need a system to keep it clean (unless you opted for a self-sustaining natural pool). Chlorine is very effective at keeping pools sanitary and can be added directly or created with a salt water system.

No matter which option you choose, Shawn Waterman, pool builder says, “The balance of chemicals is always the key. With chlorine in the right balance, your pool will always be sanitary.”

Here’s a quick overview of each option.

Chlorine

Probably the most popular option, chlorine sanitation requires adding the chemical directly into the water. According to Fixr, it will cost between $300 to $800 per year in chemicals to maintain it.

Saltwater

A saltwater swimming pool is disinfected through electrolysis, which creates chlorine from salt. The water needs to contain about a tenth of the salinity that you find in the ocean. Fixr estimates the initial cost for a salt system installation to average about $1,500 (due to the salt water generator and installation), while yearly salt and chemical costs range from $70 to $100.

Pool material options

Lastly, you will need to choose the material you want your pool to be. This decision will impact your upfront costs, ongoing maintenance costs, how long your pool will last, how durable it will be, how difficult it will be to maintain, and if it is customizable in terms of shape and size. The most popular options are concrete, fiberglass, and vinyl.

Concrete

Custom Pool Buyers – Pool Builders Las Vegas estimates a concrete pool will cost between $50,000 to $100,000 to install and $27,400 to maintain over the first 10 years. This is the most expensive option, both upfront and over time.

However, it does offer high durability and the longest expected life. Furthermore, Waterman says, “I recommend concrete or Gunite because you can shape or design them any way you like.”

Fiberglass

CustomPoolBuyers.com estimates a fiberglass pool will cost from $45,000 to $85,000 to install. As for the maintenance, the 10-year costs are the lowest of the three pool types, totaling $3,750.

This is a good option if you can find a pool with the dimensions you want, if low maintenance is important to you, and if you want a quick installation.
