The sandstone washbasin in the bathroom gives a luxurious and elegant feel. This doughnut version made of green sandstone is a delight to the eyes with a smooth polished sink inside and out. To keep your wash basin looking good, we recommend cleaning it once a week with acid-free soap and a soft cloth. This prevents limescale and keeps your sandstone sink looking good for a long time. We also recommend that you remove coarse stains, such as a drop of toothpaste, right away before you have time to leave a stain on your sandstone washbasin. You can also dip your sink with wax once a year, especially with natural stone. Make sure the sink is dry before dipping.
