A spa bath is a type of bathtub that uses jets or bubbles to create a massaging effect on your skin and muscles. The water in a spa bath is heated, often to high temperatures, which helps to soothe sore muscles and promote relaxation. Spa baths are commonly found in hotels, resorts, and luxury homes, and they can be designed for individual use or larger models that accommodate multiple people. The massaging action of the jets can help improve blood circulation, reduce stress and tension, and provide a sense of overall well-being.
