Swim Spa Buying Guide: What to Know Before You Buy

What Is a Swim Spa?

A swim spa is a hybrid between a warm-water spa and a swimming pool. It generates a continuous current that allows you to swim in place, while also offering seating and jets for relaxation and hydrotherapy.

Understanding Propulsion Systems

The most important decision when buying a swim spa is the propulsion system. There are two main types:

Jet-Driven Systems

Multiple powerful jets create a swim current. These are generally less expensive but can produce a turbulent, less consistent flow.

Propeller Systems

A large underwater propeller creates a wider, smoother, and more adjustable current. These systems—like those found in Endless Pools and certain Master Spas models—are preferred by serious swimmers.

Sizing and Space Requirements

Swim spas typically range from 12 to 21 feet in length. Measure not just the pad area, but also the access route for delivery. Most units require a crane or specialized trailer for placement.

Installation Basics

You'll need a solid, level pad (concrete, pavers, or reinforced deck), proper drainage, and a dedicated electrical circuit. Some models can be partially recessed or installed indoors.

Budget and Pricing

Entry-level swim spas start around $15,000, while premium models with advanced propulsion and dual zones can exceed $40,000. Don't forget to budget for delivery, electrical work, and ongoing maintenance.
