What Makes a SwimEx Fiberglass Swim Spa Different?

Why Choose a Fiberglass Swim Spa?
Not all swim spas are created equal—and the construction method makes a big difference in performance, maintenance, and long-term value.
Fiberglass swim spas offer a unique combination of durability and thermal efficiency. Unlike porous materials, fiberglass is smooth, non-absorbent, and resistant to algae, mold, and staining. It retains heat well and requires less maintenance over time—making it an ideal choice for both home and professional use.
Here’s how fiberglass compares to other common pool construction types:
- Concrete: Strong and highly customizable, but expensive to install and maintain. Its porous surface requires regular cleaning and sealing.
- Vinyl-lined: Lower upfront cost and easier installation, but vinyl is prone to punctures and tears—resulting in recurring liner replacements. Mold and mildew can develop between the liner and the steel pool walls.
- Acrylic: Sleek and good at retaining heat, but vulnerable to stress cracks and often requires added structural support.
- Metal: Durable and fully customizable, but can corrode over time in warm, chlorinated environments.

Unique fiberglass swim spa construction
SwimEx pools are constructed with a state-of-the-art fiberglass technique similar to high-performance luxury yachts and aircraft. Layers of fiberglass, resin, and gel coat enclose a balsa wood core. There is fiberglass on each side of a balsa wood core, creating an insulated “sandwich” that forms a virtually indestructible shell.
SwimEx pools have a small footprint. They pack a powerful punch in as little as 200 square feet of space and fit virtually anywhere. They range in size from 7′6″ to 11′5″ wide (2.29m to 3.47m) and 13′6″ to 22′ long (4.11m to 6.7m). Plunge pools come in five standard sizes or can be custom built up to 45′ long and 6′ deep.
Balsa wood core
SwimEx pools have a strong balsa wood core for superior shell strength, between layers of fiberglass and resin. As our pools are free-standing and self-supporting, this extra insulated layer helps to maintain temperatures efficiently.
Gel coat surface
Fiberglass pools have no liners. This means you never have to worry about tearing a vinyl liner or the cost of replacing one. The smooth surface doesn’t need replacing and acts as a barrier against moisture absorption and algae growth. It cleans quickly, and is extremely easy to maintain.
SwimEx pool warranty
- 10 years on the structural integrity of the unit.
- 5 years on the gel coat surface and propulsion unit (paddlewheel or propeller).
- 2 years on the motor.
