Heated towel rails are a bathroom accessory that keeps towels warm and dry while adding a touch of luxury and style to your bathroom. They come in various sizes, styles, and finishes, and can be either electric or hydronic. Electric heated towel rails are powered by electricity, while hydronic ones are connected to the hot water system in your home. Compared to traditional towel racks and radiators, heated towel rails are more efficient at drying and warming towels, and can also provide gentle heating to the bathroom.
