Activity 2 Swim Spa: Year-Round Swimming and Recovery for Your Texas Backyard

The Activity 2 gives you the best of two worlds in one footprint: a generous swim zone for exercise and an inviting seating area for relaxation. At 18 feet long and holding roughly 3,302 gallons, it offers real room to move while still fitting comfortably in a Houston backyard. If you are still comparing models, the swim spa collection at Fonteyn Houston is a good place to start.

An 18-foot swim spa made for swimming

At the heart of the Activity 2 is the River Swim System, which produces a smooth, adjustable current that flows the length of the swim zone. You set the speed to match your level, from an easy warm-up to a demanding workout, and simply keep swimming in place. Want to see how the current works? The guide to the River Swim System explains it in plain terms.

Train against an adjustable current

Five turbo swim jets and two floor swim jets shape a steady, even flow that suits swimming, aqua jogging and low-impact conditioning. Because you control the resistance, the same spa works for a first-timer and a serious swimmer. Many owners rely on it for fitness and rehabilitation alike, and the overview of swim spa benefits for health, fitness and recovery covers what to expect.

Relax and recover after every session

When the swim is done, you move to the seating area, where three ergonomic seats and a full set of hydromassage jets go to work on tired muscles. Targeted massage helps ease tension in the neck, shoulders and lower back, so the Activity 2 supports both the effort and the recovery in a single spa.

Made for year-round use in Houston

Texas weather invites outdoor swimming for much of the year, and energy-efficient Hybrid Heating™ keeps the water at a comfortable temperature whenever you want it. Combined with triple-layer insulation and an insulated, maintenance-free cabinet, the Activity 2 holds its heat efficiently, so you can keep enjoying it year round, from a hot Houston summer to a cool winter evening.

Clean water with less effort

An ozone-based water care system works quietly in the background to keep the water fresh and clear, which means fewer chemicals and less hands-on upkeep for you. A digital touch panel puts temperature, jets and lighting within easy reach, so day-to-day use stays simple.

Comfort, lighting and sound

A StarBrite interior LED lighting system sets the mood for an evening swim, while the built-in audio and WiFi-ready controls let you enjoy your music and manage the spa with ease. Every detail is designed to make time in the Activity 2 feel effortless.
