① Suitable for sealing and made of 100% food grade silicone: The bathtub stopper, crafted from silicone material, can seal sinks or bathtubs effectively with minimal leakage. It is made of 100% food grade silicone to help ensure the safety of children by avoiding exposure to harmful metals or plastics (BPA safe). It should be noted that it is only suitable for flat and smooth surfaces. ② Easy to use: Before filling the tub or sink with water, use the tub stopper to cover the drain hole, and remove it after use. This simple operation saves effort. Additionally, the suction cup design is convenient for storage when the tub stopper is not in use. ③ Long-lasting sealing: The shower bath drain stopper can maintain a seal throughout the night without significant water leakage. ④ Universal size: One size is designed to fit various applications, providing a secure and snug fit with good grip, suitable for use in kitchens, bathrooms, laundry rooms, utility rooms, and Jacuzzi tubs. ⑤ If you find it troublesome to deal with hard-to-pull plugs that easily get dirty, or if you are still using original metal stoppers or inexpensive plastic stoppers, you may consider replacing them with our WSZCML silicone bathtub stoppers. These stoppers are large, round, and flat, making them easier to work with different size holes in tubs, bathtubs, kitchen sinks, etc. As they are made of silicone, they are less likely to slip around compared to cheap plastic stoppers. The super slim and flat drain stopper design contributes to effective sealing with no leakage. They can cover the drain and stop all water flow easily, allowing you to use the water for your evening cleaning routine. They have good suction but are easy to remove; adults can lift them up by slipping a finger under the side, while it may be a bit more challenging for children. If you dislike unpleasant smells coming from the drain, our tub drain cover can cover the shower drain well when the shower is not in use to prevent such smells. It is also suitable for travel, especially when visiting foreign countries where sink stoppers often do not work well, making clothes washing difficult.
