Activity 1 Deep Swim Spa: Deeper Water for Year-Round Swimming in Houston

The Activity 1 Deep takes the compact Activity 1 footprint and adds depth, standing a full 60 inches tall so you can swim, float and recover in deeper, more supportive water. At 155 inches long, or nearly 13 feet, it still fits comfortably in a Houston backyard while giving you a more open-water feel. If you are weighing your options, the swim spa collection at Fonteyn Houston is a good place to start.

A deeper 13-foot swim spa

Extra depth changes the whole experience. With water reaching a full 60 inches, you get more buoyancy and a more natural swimming position, which many swimmers find easier on the joints. The multi-layer acrylic shell and durable synthetic support structure keep everything solid season after season.

Swim against the River Swim System

The River Swim System 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 hard training set, and simply keep swimming in place. The guide to the River Swim System explains exactly how it works.

Train with turbo swim jets

Five turbo swim jets and two floor swim jets, driven by a 3 HP pump, shape a steady, even current for swimming, aqua jogging and low-impact conditioning. Because you control the resistance, the Activity 1 Deep suits everyone from beginners to dedicated athletes. Explore the fitness collection to see how it fits an active lifestyle, and the overview of swim spa benefits for health, fitness and recovery covers what to expect.

Relax and recover after every swim

When training is done, three ergonomic seats and a full set of hydromassage jets go to work on tired muscles. Aqua rolling massage, soft-tissue massage, lumbar support and an aromatherapy system help ease tension in the neck, shoulders and lower back, so recovery is built right into your routine.

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 1 Deep holds its heat efficiently, so you can keep enjoying it 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.
