What things are made out of rock in a bathroom?

In a bathroom, common items made out of rock include granite or marble countertops, which provide a durable and aesthetically pleasing surface. Stone tiles, such as slate or limestone, are often used for flooring or wall surfaces. Additionally, some sinks and bathtubs are crafted from natural stone for a luxurious look. These materials not only enhance the bathroom's decor but also offer resilience against moisture and wear.
