Are you asking about the brand or the shape or function? The brand is of course the top ten brands. The shape is round and the function is high-tech. The point: look at its constituent materials. The common ones are ceramic cylinders, wooden barrels, cast iron cylinders, acrylic bathtubs, ABS bathtubs, recycled materials and pearlescent boards. Among them, acrylic bathtubs and pearlescent bathtubs have higher market share. Acrylic bathtubs are changeable in shape, light in weight, and have good thermal insulation effects, but have the disadvantages of low hardness and easy scratches on the surface; pearlescent bathtubs have a smooth surface and pearl-like luster, are durable, good in heat preservation, and easy to install in weight. Second point: the less noise the better. When purchasing, test which one is less noisy. The third point: compare and observe the smoothness and gloss of the surface of the bathtub to choose the bathtub.
