5 Things To Consider When Building An Indoor Pool

Having an indoor pool is a blessing as long as you can afford it. There are several advantages of building an indoor pool including privacy and enclosure. Plus, the outside weather does not disturb your swimming schedule. However, there are some important things to know before considering an indoor pool and consulting swimming pool builders.

Size, Shape, And Placement Of Pool

When it comes to building an indoor pool, consider the size, shape, and placement of the pool. You need to get them right. Most people ignore these factors and end up with complications down the road that only cost them additional expenses.

Based on the shape and size, you can build your pool using common pool materials (concrete, vinyl, fiberglass). Furthermore, you will need to find out if you already have an existing area to build the pool or if you will need to create one from zero.

This is important as the available space will decide the shape and size of your pool. So, if you are building an indoor pool, you will need to make sure that you have the appropriate dimensions to install one without any restrictions. Moreover, you will also need to think about the pool accessories and equipment.

Planning Permissions And Pool Regulations

Once you have decided on the size, shape, and placement of the pool, you have to move onto the permission and regulations phase. Some countries or states in particular have strict regulations governing the building of indoor pools.

The biggest risk with indoor pools is leakages. If a mishap were to take place, your neighbors along with the surroundings might be threatened as well. That said, before building an indoor pool, you will need to find out what the local laws have to say about indoor pools.

And since you will most probably be working with a contractor and an architect, they would make sure that your pool abides by the regulations. In some states, the regulations might not be that strict but if your pool has a specific design or features, etc. you still might need to get permission.

Structural Integrity And Waterproofing

As mentioned earlier, indoor swimming pools can be risky if they happen to leak. This means that your indoor pool should be properly waterproofed so that even if a leak were to take place, it does not affect the structural integrity of the house. Not only that, but leakages could also cause mold and mildew to grow.

For this reason alone, waterproofing alone can be the most expensive part of the process. However, without it, you will simply risk leakages in the future that will not only cost you money but also additional time and effort.

In addition to that, most contractors believe that waterproofed drywall is sufficient enough for indoor pools. But, others go for more rigorous options to ensure close to zero leakage probability.

Heating And Air Ventilation

Heating and air ventilation are two important factors that you need to keep in mind while building an indoor pool to control evaporation, as some laws regulate the air quality of indoor pools. While you may not have to worry about chlorine and pH levels since the water is not exposed to the sun but the operational costs of heating and ventilation hold a lot of significance.

For this, you will need to invest in a good quality dehumidifier for the room that can replace the humid air with fresh air. And as the humidity is reduced, the evaporation can be high that can only be controlled via temperature. Therefore, the heating and air ventilation equipment costs are additional and need consideration.

Cost And Construction

Finally, it comes down to the cost and construction. Building an indoor pool is a lot more than just the factors mentioned above. You will need to consult an expert who will utilize different techniques based on the soil’s structural strength, design, and quality.

On top of that, you will have accessories, design, features, equipment, insurance, and several other things lined up. When added up, the total cost could be high and therefore, it is better that you first get an estimate so that you are able to make an informed decision.


Building an indoor pool is surely an exciting process. But you need to keep the above-mentioned factors in mind to narrow down your options and make wise decisions. Plus, always focus on practicality rather than counting the features and hire qualified pool contractors Long Island. This is the only way to make your money worth it.
