Answer 2

Answer: Limestone floor tiles

Natural limestone is a terrific material because of its inexpensive cost and vast range of natural colors. Limestone may take on a wide range of colors due to the minerals it contains. The unique grain patterns and textures of limestone are best seen when the stone is cut with a chisel or a straight edge. If laid and maintained correctly, limestone tiles in the kitchen or bathroom might be a stunning aesthetic element. If paved walkways and landscape features are required, they can be built at the organization's expense. The best place to get cheap limestone floor tiles is at Buytilesandmore.com.
