Usually, round bathroom sinks are available with the standard size: 42 cm diameter, 15 cm height and 20 kg weight. The aftercare includes two steps: first, a treatment with a professional solution that will prevent limescale deposits and second the daily maintenance. For the second step we recommend LTP Stone Wash, professional detergent that will not attack or remove the sealant applied on the natural stone surface. Keep in mind: You can combine round natural stone bathroom sinks with a bathroom countertop from similar material, cut-to-size for your needs.
