Safety Environmental Protection: Our anti-bacterial tub and shower mats are made of high quality, allergen-free vinyl. This bath mat is a great choice for homes, gyms, spas, etc. Durability and Drainage Holes: Our oversized pillow measures 100 x 40cm and provides excellent coverage. Many other rugs form the smallest starting area of the tub. While other rugs are very durable and produce a damp underside (which speeds up mold growth), our rugs have many small holes that allow water to circulate. Machine washable : Our durable rugs are machine washable and easy to maintain. Clean anytime, just throw the rug in the washing machine to enjoy the fresh look Satisfaction Guarantee: It is normal for the newly opened product to have a certain odor. Rest assured, put the mat in a ventilated place for a while, the smell will disappear or put it in the washing machine before use. Delivery quantity: one piece
