Building an indoor pool can be a costly investment in any property, whether it’s a home, a business, or a fitness facility. Humidity control is an essential part of that investment. An effective indoor pool dehumidifier system maintains a comfortable pool environment and extends the longevity of your facility by controlling moisture.

High-quality dehumidifier systems can be costly, but going with the most affordable option can be even more so in the long term. Buying underperforming components can mean even greater maintenance and replacement costs down the line – not to mention the threat to your guest’s health and comfort posed by excess moisture in your pool facility.

This breakdown of costs associated with building a new indoor pool dehumidifier system provides a rough idea of what to expect. Keep in mind, each project is different and will require varying levels of investment.

Components of Indoor Pool Dehumidifier Systems

Indoor pool dehumidification systems consist of several components working together to manage humidity. These are the tools that any effective system should have.

1. Dehumidification Unit
2. Air Handling Unit (AHU)
3. Ventilation
4. Sensors and Controls

Installation and labor costs – as well as ongoing maintenance costs – are also important to keep in mind when estimating a system’s total price tag. Again, some projects may have other costs that come into play, especially if you’re building a new facility or need to make extensive modifications to an existing one. But these components form the basis of most indoor pool dehumidification projects.

Indoor Pool Dehumidification System Cost Breakdown

Note: The price ranges listed below are rough estimates of costs and should not be taken as a quote or exact cost range. Each indoor pool dehumidification project is unique, with many distinguishing factors that influence pricing. Your project may fall above or below the listed ranges in total costs. 

1. Dehumidification Unit

The dehumidification unit is the heart of the system. It extracts moisture from the air and maintains the desired humidity levels. The cost of these units varies widely based on their capacity, efficiency, and brand.

• Small Residential Units: $2,000 – $6,000
• Medium Commercial Units: $10,000 – $30,000
• Large Commercial Units: $40,000 – $100,000+

Residential units are typically less expensive, as they are designed for smaller spaces. Commercial and industrial units, on the other hand, are more robust and capable of handling larger volumes of air.

2. Air Handling Unit (AHU)

The AHU is responsible for distributing the conditioned air throughout the indoor pool area. It includes fans, filters, and heat exchangers. The cost of an AHU depends on its size and complexity.

• Residential AHU: $1,500 – $5,000
• Commercial AHU: $5,000 – $15,000
• Large Commercial AHU: $20,000 – $50,000

The AHU must be adequately sized to ensure efficient air distribution, which directly impacts the effectiveness of the dehumidification process.

3. Ductwork and Vents

Ductwork and vents are essential for directing the dehumidified air to various parts of the indoor pool area. The cost depends on the length and complexity of the ductwork required.

• Residential Ductwork: $1,000 – $3,000
• Commercial Ductwork: $5,000 – $20,000
• Large Commercial Ductwork: $25,000 – $50,000

Properly designed and installed ductwork ensures uniform air distribution and prevents any areas from becoming overly humid.

4. Sensors and Controls

Sensors and control systems are vital for maintaining the desired humidity levels. These components monitor the environment and adjust the dehumidification process as needed.

• Basic Control Systems: $500 – $2,000
• Advanced Control Systems: $3,000 – $10,000

Advanced systems offer more precise control and can be integrated with other building management systems for better efficiency.

5. Installation and Labor Costs

The cost of installation and labor varies depending on the complexity of the system and the region. This includes the cost of hiring HVAC professionals to install the dehumidification unit, AHU, ductwork, and control systems.

• Residential Installation: $2,000 – $5,000
• Commercial Installation: $10,000 – $30,000
• Large Commercial Installation: $40,000 – $100,000

Professional installation ensures that the system operates efficiently and reduces the risk of future problems.

6. Maintenance and Operating Costs

Ongoing maintenance and operating costs are essential to consider. Regular maintenance ensures the system continues to function efficiently and prolongs its lifespan.

• Annual Maintenance: $500 – $2,000
• Energy Costs: Varies based on usage and energy rates

Energy-efficient systems may have higher upfront costs but can save money in the long run by reducing operating expenses.

Total Cost Estimation

Combining the costs of all components and considering the variations based on residential, commercial, or industrial settings, the total cost of building a new indoor pool dehumidifier system can range significantly:

• Residential Systems: $7,000 – $20,000
• Commercial Systems: $30,000 – $80,000
• Industrial Systems: $150,000 – $300,000+

Make the Investment in Dehumidification

Investing in a high-quality dehumidifier system for an indoor pool is essential for maintaining a comfortable and safe environment. While the initial costs can be substantial, the long-term benefits of protecting the building structure, preventing mold growth, and ensuring the comfort of pool users make it money well spent.
