Are you tired of the same old rectangular pool design? Do you want a pool that not only stands the test of time but also makes a statement? The choice between gunite and concrete pools is more than a decision. It’s a poolside revolution waiting to happen.

Gunite and concrete are the top choices for in-ground pools, competing for the best swimming experience. Both offer durability and luxury at a price worth diving into. But let’s not dive in yet. These pool materials have some vital, game-changing differences you need to consider.

In this article, we’ll take a close look into this showdown. It’s not a choice between pools. It’s a choice between elegance and endurance. Let’s dive deep into the concrete vs gunite pool debate – a clash of notable materials in pool construction.

Gunite Vs. Concrete: Which Is Best For Your Pool?

Pool installation consists of many steps. It includes digging, installation of plumbing lines, steel reinforcement, installation of electrical cords, and city inspections. Afterward, concrete application, curing, decking, tiling, and coping will follow. Lastly is finishing the interior.

For concrete application, this is where your team would lay concrete to the steel reinforcement. There are two ways to perform it, one via pouring and one through spraying via a hose. Gunite belongs to the latter.

What Is A Concrete Pool?

A concrete pool is the most common type in most houses. Constructing one utilizes concrete, which is a mix of water, cement, sand, and a coarse kind of aggregate. The aggregates are materials comprising small particles, usually small pulverized stones or gravel. When constructing, workers pour concrete into a steel form and then add finishing plaster or tiles.

Concrete pools are very durable and customizable. They allow homeowners to craft unique shapes and depths that suit their style and needs. The downside of having one is it can take several weeks to build. Concrete pools also demand regular maintenance to preserve their pristine condition.
