Can a Swim Spa Be Used as a Hot Tub?

Modern swim spas are designed to provide both exercise and relaxation in a single unit. Many models feature integrated seats with hydrotherapy jets so you can soak and unwind after your workout.

Swim spa vs hot‑tub functionality

A dedicated hot tub focuses on hydrotherapy. It is smaller, holds less water and contains multiple massage seats and jets that target different muscle groups. Water temperatures are typically maintained around 37–40 °C for deep relaxation.

Swim spas are larger because they include an open swim area. To provide hydrotherapy, manufacturers incorporate bench seating or lounger seats with jets at one end. Some premium models have dual‑zone designs with a separate hot‑tub compartment, allowing you to keep the swim area cooler (around 29–31 °C) for exercise and the spa side warmer for soaking.

Pros and cons of using a swim spa as a hot tub

  • Dual use: A swim spa gives you a place to swim and a place to relax without buying two separate units.
  • Water volume: Because a swim spa holds more water, it takes longer to heat and costs more to run than a standalone hot tub.
  • Seating comfort: Swim spas usually have fewer seats and jets than a dedicated hot tub, so the hydrotherapy experience may be less intense.
  • Flexibility: Dual‑zone models let you set different temperatures for swimming and soaking, maximising comfort.

When to choose a separate hot tub

If your primary goal is relaxation and socialising, a separate hot tub may be better because it offers more seating, more focused jets and lower running costs. However, if you want the versatility of swimming in place and enjoying a warm soak in one compact footprint, a swim spa with built‑in seating or a dual‑zone swim spa can meet both needs.
