A bath mat is made specifically for preventing slips and wet floors in your bathroom. Bath mats are used right in front of your bathtub or shower to absorb water after you bathe. They are typically extra absorbent and offer non-skid features for safety.
As with the rest of your bathroom linens, your bath mat doesn't need to be a perfect match. Instead, consider the shades and patterns found in your towels, shower curtain, wall color, and other bathroom accents, and choose a hue that coordinates.
