1, safety first. Foot bath is a kind of electric appliance with mixed water and electricity. When it is electrified, the human body is in direct contact with the water in the basin, so safety naturally becomes the primary consideration when buying foot bath. At present, there are two kinds of foot baths that can be heated on the market: direct heating and indirect heating. The direct heating type has the potential safety hazard problem after the anti-leakage device is aged or damaged, so it is difficult to be foolproof. The indirect heating method is steam heating, which can ensure that the foot bath water does not contain any charged body and eliminate the hidden danger of electric leakage. Therefore, it is necessary to choose a foot bath heated by steam. Although the heating time is a little longer, it can ensure the safety of use to the greatest extent.

2. Pay attention to quality and function. We should choose products with good reputation, big brand, perfect service and stable quality. Choose a foot bath tub with complete functions, especially the function of decocting traditional Chinese medicine, because it can automatically generate foot bath liquid, greatly reducing the trouble of soaking feet and frying traditional Chinese medicine at ordinary times, and it can also be used for multiple purposes when heating air in winter with humidification function, which is more economical and practical.

3. Pay attention to convenience. In terms of capacity, the depth of the basin is different and the operation is different. If you choose a deep basin of 25-30 cm, you should pay attention to whether it has the drainage function of the deep basin, otherwise it will be very inconvenient to pour water. If it's for the elderly, try to use those with convenient operation and few control keys, and it's best to have automatic programming.
