- Odor and insect proof design: The sink drain pipe uses an anti-odor core that automatically closes to prevent odors or pests from entering the room, helping keep the bathroom fresh. - Drain connector: Flexible drain hose can be installed on the bottom or side of the sink, offering multiple drainage options. It fits with dividers, drawers, wall drains, or floor drains. - Easy installation: No special tools or skilled labor required. Manual installation is straightforward. It fits sink holes with a diameter of 40 mm to 50 mm and is suitable for both non-overflow and overflow basins. Use scenarios: - New bathroom sink installation with standard 40–50 mm holes and either overflow or non-overflow basins. - Retrofit in a vanity or cabinet where a divider or drawer sits behind the sink, allowing routing from the bottom or side without interference. - Rooms with various drainage layouts (wall drain, floor drain) where a flexible connection simplifies alignment and saves space.
