Installing a Double Bowl Sink is one of the most rewarding upgrades for any kitchen, combining functionality with modern design. A proper setup ensures efficient drainage, balanced water flow, and long-term leak-free performance. As a trusted manufacturer and wholesale supplier, LANSIDA provides high-quality stainless steel sinks and accessories that make installation faster, cleaner, and more reliable.

Understanding Double Bowl Sink Structure

A double bowl sink features two separate basins, allowing multitasking such as washing and rinsing simultaneously. Most units come with:

LANSIDA’s sinks are designed with precision-formed edges, uniform thickness, and anti-condensation coatings, ensuring both aesthetics and performance meet international standards.

Step-by-Step Installation Process

1. Prepare the Sink Area

Before installation, ensure that the countertop cut-out matches the sink dimensions. LANSIDA’s double bowl sinks are precisely manufactured, reducing on-site trimming and guaranteeing a snug fit. Clean the area to remove dust or debris.

2. Mount the Sink

Apply a waterproof sealant along the countertop edge. Lower the sink carefully, ensuring both bowls are aligned evenly. Secure it with mounting clips provided in the package. LANSIDA’s sinks feature pre-drilled mounting points, simplifying this process for both under-mount and top-mount models.

3. Install Drain Assemblies

Insert the strainers into both bowls and tighten the gaskets underneath. Use plumber’s putty to create a watertight seal. LANSIDA provides high-precision drain fittings that connect seamlessly to standard plumbing systems.

4. Connect the P-Trap and Waste Line

Join both drain outlets using a Y-connector or double-bowl P-trap kit. Adjust the alignment to ensure smooth water flow. Tighten all slip nuts without over-torquing. This ensures balanced drainage between the two bowls.

5. Test for Leaks

Once all parts are connected, run water into both bowls. Check every joint for drips. If any appear, re-seal with Teflon tape or re-tighten the fittings. LANSIDA’s sinks, when properly installed, maintain leak-free performance for years under normal household use.

Professional Tips for Reliable Installation

• Always use 304 or 316 stainless steel sinks for better corrosion resistance.

• Apply anti-mold sealant to prevent moisture damage around the countertop.

• Keep the drain lines short to improve water discharge efficiency.

• Regularly inspect the P-trap to prevent odor or clogging.
