HUNDREDS OF SUCTION CUPS!! Our antibacterial bath and shower mats feature 324 Gorilla Grip suction cups that help hold in place on smooth, clean surfaces. This bath mat is a great choice for the home, gym, spa and more! Not for use on newly refinished surfaces. | LARGER SIZE and FEATURES HOLES: Our extra large and generously sized mat is 35 x 16 inch and provides excellent coverage. Many other mats are smaller leaving areas of your tub exposed. And while other mats are solid creating a moist underside (which can accelerate mold growth), our mat features small holes throughout to allow water to circulate. | /!\ WARNING: Prevent Falls: Secure suction cups before each use. Mat will only attach to clean, smooth surface. Not for use on textured, tiled, or non-smooth surfaces. Do not use bath oils – may cause slipping. | ANTI-BACTERIAL: Antibacterial and Mildew Resistant, BPA Free, Non-Toxic, Phthalate free, Latex Free, No Toxic Smell. Plus, all of our mats come with a 10-Year No Questions Asked Warranty. If you are at all unsatisfied with your product, please contact us (through Amazon if past the standard return window) and we will be happy to assist you. At the end of the day we want our customers to be happy! | EASY CLEAN: Our mat is machine-washable to uphold its fresh appearance. We highly recommend that you wash your mat prior to use. Wash in your washing machine on cold with gentle detergent (no bleach) and air dry. Rinse and dry your mat periodically to remove oily and slippery buildup that may occur from various soaps and hair products. Should you encounter a strong odor when the package is first opened, we recommend allowing the mat to air out in a well ventilated area for 24 hours before use.
