How to Build a Gunite Pool 

Step 1: Design the Pool

Every good pool always starts as a design on paper. As you are designing the pool, you need to be clear of how you will use it and where you will install it as this determines the shape, size, and depth.

Step 2: Identify the Location and Excavate

You should already have the pool location in mind long before you even start designing. Hence, once you have the design, you need to identify the location and starting digging up.

This step always starts with outlining the pool area to ensure you get things like the shape and size right as you excavate.

Depending on the size and depth, excavating the pool area can take anything from a few hours to a few days.

Step 3: Install Plumbing

After excavation, you need to install the plumbing system and other things like electric and gas lines, as these might be hard to set up once you have the frame in place. Plumbing for these pools typically uses PVC pipes.

Step 4: Setup the Rebar Frame

Once the plumbing and other supporting fixtures are in place, you can start the actual gunite pool construction process.

Here the first thing to do is install the rebar frame. The frame needs to cover the entire pool and should also have the correct shape.

A rebar frame forms the pool’s base and helps the gunite adhere well to create a solid pool structure.

Step 5: Install Gunite Structural Shell

With the frame in place, you can now spray the gunite. This step takes several hours, and good workmanship is vital here to ensure you get sturdy and long-lasting walls.

Also, it is vital to give the gunite enough time to cure. It takes around 24 hours to harden and up to 2 weeks to cure completely. You need to water the gunite up to thrice a day for about a week.

Step 6: Finish the Pool

The last step is to finish up the pool to get it ready for use. Here you should install all the plumbing equipment the pool needs, install tiles or any other finish you prefer, and fix the edge coping.

Once all this is done, you need to fill up the pool and add the necessary pool chemicals, and it will be ready to use.


Gunite swimming pools are highly durable and flexible as you can make them in any shape and size you want. Additionally, these swimming pools allow for greater customization when it comes to the finish options.

Although it might be a little more expensive to install and maintain, the pool is often worth every buck. If you take good care of it, you can be sure of enjoying it for many years to come.
