When the body is in a hot tub, the increase in temperature causes blood vessels to dilate and blood flow to accelerate, which provides more oxygen and nutrients to skin cells, promoting cell regeneration and repair. At the same time, the enhanced blood circulation can accelerate the excretion of waste and toxins, further purifying the skin.

Improved blood circulation is one of the most significant benefits of outdoor hot bathtubs. When you soak in hot water, the skin and tissues of the body are heated by the warm water, and the blood vessels expand accordingly. This is medically known as vasodilation.

a 10-12 cm thick concrete slab with a steel mesh can safely carry a small outdoor hot bathtub (about 500-800 kg). For large outdoor hot bathtubs, it is recommended to increase the thickness of the concrete slab to 15-20 cm and use high-strength concrete (C30 or above) to ensure that it can safely and stably carry a total weight of 2000 kg or more.

The most direct and effective preventive measure is to seal all possible access points for mice. Mice can get in through extremely small gaps, so when installing or inspecting an outdoor hot bathtub, pay special attention to cracks around the tub, holes in pipes, and loose joints.

Terraces are often used to place lightweight furniture, flower pots or outdoor activities, but their load-bearing capacity is usually limited to about 200 to 500 kilograms per square meter. This load-bearing standard is suitable for ordinary living use, but it may be overwhelmed when faced with an outdoor hot tub filled with water.

Choosing to place the outdoor hot bathtub in the sun will undoubtedly allow the user of the bathtub to enjoy the warmth of natural light. But this choice is not only beneficial. Outdoor hot bathtubs exposed to the sun may face some challenges in different seasons and environments.
