Perfect Compatibility: The sink strainer features a new small diameter design (30mm), suitable for most sink holes ranging from 34mm to 40mm (depth: approximately 50mm). Internal Anti-Clogging Basket: Unlike standard stoppers, the upgraded sink drain stopper includes an internal anti-clogging basket that collects hair and prevents blockages. High-Quality and Durable Material: Our bathroom sink stopper is constructed from thick, crack-resistant stainless steel and brass for enhanced durability, a smooth finish, and long-term performance without cracking or leaking. One-Click Quick Drainage: The sink drain stopper has a sleek spherical design with excellent resilience, allowing for quick sealing and one-touch drainage. The thick silicone seal helps prevent sewer odors, maintaining fresh air in your home. Easy Installation: Tool-free setup makes it simple for anyone to install the pop-up drain. With a straightforward design, simply remove the old drain and insert the new unit to complete installation.
