In a traditional swimming pool, swimming relies on the length of the pool to complete the back-and-forth motion; in a swim spa tub, swimming relies on resisting the water current. When the water flow speed and the swimmer's speed are balanced, the user can swim continuously in a fixed position.

In most cases, this is perfectly normal. A swim spa tub is essentially an open water system, especially when installed outdoors, where the water surface is directly exposed to the air. As long as the water surface is exposed, evaporation is inevitable.

Yes, a swim spa tub can absolutely function as a hot tub. A swim spa tub is an integrated spa device that typically possesses the following core features: • Large water volume • Constant temperature heating system • Powerful water flow system • Water circulation and filtration system etc.

Although a luxury swim spa tub requires a significant initial investment in purchase and installation, the largest long-term expenses are typically water and electricity bills—in other words, operating costs.

• Compared to a regular bathtub, maintenance costs are certainly higher due to the need for electricity, water quality maintenance, and consumable replacement. • Compared to a traditional swimming pool, a swim spa's maintenance costs are actually lower because the water volume is smaller and easier to maintain.

Typically 2.5 to 4 meters long, they are not suitable for long-distance freestyle swimming but are suitable for short-distance swimming or stationary swimming training. They are moderately deep (1.2 to 1.5 meters), sufficient for floating, leg kicking, and arm stroke training, but not for large-scale water sports.
