Sitz Bath Tub is a plastic tub that fits over the commode. Fill it with water, a saline solution or one of our proprietary sitz bath.It allows only the hips, buttocks and genitals to be soaked. Convenient and comfortable. Use it after surgery or childbirth or for haemorrhoids. Often better than soaking in a tub, because it allows the sitz bath blend to be concentrated on just the area to be treated.
