Why Build Your Own Swim Spa?

  1. Major Cost Savings

A biggest reasons people choose to build their own swim spa is the significant cost reduction compared to prefabricated models. Commercial swim spas can cost anywhere from $15,000 to $50,000 or more, depending on size and features. Building your own swim spa, lets you cut costs dramatically. It’s not unusual to complete a swim spa project for as little as $5,000 to $10,000, or even less, depending on the materials and equipment you choose to incorporate.

By sourcing your own build materials and purchasing swim spa equipment directly from Custom Built Spas, you can eliminate retailer markups, expensive installation fees, and unnecessary features that add to the cost but not necessarily to the functionality.

  1. Full Customization

Pre-made swim spa models,  limit you to the manufacturer’s designs. The DIY swim spa lets you build to your own exact specifications. Want a longer or deeper swim area? Prefer a particular seating layout? Need extra powerful jets or a specific heating system? Taking the DIY approach lets you tailor every aspect of your swim spa to suit your needs. Whether it’s for relaxation, therapy, fitness, or a combination of all three, your in charge.

Some customization options include:

  • Size & Shape – Build as large or compact as your space allows.
  • Jet Configuration – Choose the swim-jet type and placement and you can add hydrotherapy jets for additional comfort.
  • Current System – Install a powerful swim jet system for resistance training or a system for causal swimming or exercise.
  • Heating & Filtration – Pick the best heating and filtration system for your climate and usage.
  • Lighting & Features – Add LED lighting, waterfalls, or even built-in seating for a personal touch, no rules.
  1. High-Quality Materials at a Fraction of the Cost

Quite often a commercial swim spa will be made with a lightweight acrylic shell or fiberglass shell, both can be prone to cracking or fading over time. Building your own, you gives you the option to select durable materials, such as concrete, or concrete block, ensuring longevity and added strength.

By using quality components from Custom Built Spas, you can build a swim spa that rivals or surpasses commercial models in durability and performance, all while staying within your budget.
