Carpets are great home/bathroom essentials because:
They offer a cushion underfoot that makes for comfy walking, especially when barefoot.
They are used for cleaning your feet before entering the house or rooms.
They help you dry your feet fast.
They help you prevent slipping when your feet are wet. This type has a pathway-design for added slip-resistance.
They make coming out of a steamy shower onto the bathroom floor less jarring than stepping onto a cold tile or stone floor.
