Struggling to determine the best swimming pool plant room size to meet your requirements?

Regardless of whether you’re searching for a general plant room size rule of thumb or more specific plant room size requirements, the engineering experts here at the Chemsol Group can help.

Below, we explain how to determine the best commercial or domestic swimming pool plant room size to meet your needs as well as the minimum dimensions for a pool plant room if you’re trying to save space.

How to determine what size a plant room should be

When it comes to ensuring your pool plant room can be easily serviced and maintained, it’s crucial that it meets all the necessary plant room size requirements. So, which factors influence the size of plant room you need? Our expert team explain below!

Size of the pool

The dimensions of the pool will naturally play a key role in determining the size of the plant room. This is because larger commercial pools will typically require more powerful (and therefore bigger) heat pumps and filtering equipment to keep the water at the right temperature and in good condition.

Size of the equipment

The plant room must also be large enough to comfortably house all the necessary equipment required to keep the pool or spa in good working order.

Depending on the type of heat pump required, there should be enough space around the equipment to ensure good airflow as this helps to prevent overheating and supports efficient operation.

Plus, if you want to add insulation to the room to reduce noise pollution or store personal protective equipment and pool cleaning chemicals in the plant room, this will also add to its overall size.


Should any of the pool filtration equipment stop working correctly, easy access to repair this equipment is essential. The engineer should be able to easily move around the equipment, ensuring they have a safe and sufficient working space.

Not only should the engineer be able to work safely in this space, but the height of the room and doors must also be designed and sized to allow for the easy replacement of filters and filter materials.

How small can a pool plant room be?

As mentioned above, the best swimming pool filtration plant room size is determined by a variety of factors. However, clear working space and airflow around the equipment is essential, so a pool plant room can only be as small as the equipment allows.

As smaller plant room equipment is needed for smaller pools, opting for a pool with more modest dimensions can therefore help to reduce the necessary swimming pool plant room size.
