At Watchman Pools, we can design spas for various activities, from relaxing soaks to invigorating hydrotherapy sessions.

 One of the greatest advantages of concrete spa pools is their customisability. Since we build them from scratch, you have complete control over the spa’s size, shape, depth, and features. This design freedom means you can also add unique features, like massage jets, air blowers, or other spa accessories. Our custom spa builders can add unique design elements, such as built-in seating, waterfalls, or lighting, to achieve the desired look and feel. Choose tiles, stone, or plaster finishes to match your home’s design.

Concrete spa pools are also known for their durability and longevity. The reinforced concrete shell is robust and resistant to damage from weather, chemicals, and wear and tear. With proper maintenance and care, a well-built concrete spa can last for decades, making it a smart investment for homeowners.

Here are some common questions we get asked. If you have a specific question please get in touch!

What are the rules and regulations for concrete spa pools?

In New Zealand, spa pools are classified as small, heated pools. They do not need to be registered with any authorities if they meet the following criteria:

  • The water’s surface area is 5 square metres or less.
  • The spa pool is 760mm above the surrounding ground or decking.
  • The spa pool has no steps.
  • There’s a 1200mm clear zone around the spa.
  • There’s a compliant, lockable spa pool cover.


If your design ideas do not meet these criteria, we will discuss the relevant rules and regulations for your project.

How much does a custom concrete spa pool cost to install?

The price of your custom spa pool will depend on a few factors, including the size, number of seats, jets, and water features. Plus, don’t forget to consider additional costs, such as the spa pool’s cover and any landscaping work that needs to be completed in the surrounding area.

How much does it cost to run a spa pool?

On average, the monthly operating costs for a spa pool in New Zealand can range from $20 to $60 or more. The ongoing costs of a spa pool include the following expenses:

  • Water, chemicals, and test kits 
  • Energy and heating costs 
  • Maintenance, repair, and part replacement costs. 
  • Insurance costs
  • Usage patterns

What are the maintenance requirements for a spa pool?

Maintaining a spa pool involves similar steps to caring for any other type of pool. To maintain your spa pool and keep it working at its best, here are the typical maintenance steps.

  • Regularly test and balance the water chemistry to keep it safe and clean.
  • Clean or replace filters as needed to ensure proper water circulation.
  • Routinely inspect the spa’s equipment—pumps and heaters—to catch any issues early.
  • Clean the spa’s surfaces and empty the skimmer and pump baskets to prevent debris build-up.
  • Cover the spa when not in use to reduce heat loss and prevent debris from entering.

Can a spa pool be integrated with an existing swimming pool or landscape?

Yes! We can integrate spa pools with an existing swimming pool if the landscape and pool design allow for it. Bring our team your project ideas, and we will discuss your options based on your requirements and existing pool and landscape.
