How to Install a Horow Top Mount Sink: A Step-by-Step Guide

Installing a top mount sink can significantly enhance the functionality and aesthetic of your kitchen. Horow’s range of top mount sinks combines durability and style, making them an excellent choice for any home. Follow this step-by-step guide to install your Horow top mount sink with ease.


Before starting the installation process, gather all necessary tools and materials. You will need a jigsaw, a drill, a measuring tape, a pencil, silicone sealant, and plumber’s putty. Ensure your new Horow top mount sink fits the dimensions of your existing countertop cutout or prepare to create a new one.

Cutting the Countertop

Measure and Mark: Place the sink upside down on the countertop. Trace around the sink’s edge with a pencil to mark the cutting line. Measure inwards by about half an inch from this line to create a second line, which will be your cutting guide.

Drill Pilot Holes: At each corner of the inner line, drill a pilot hole. These holes will help you start the jigsaw blade.

Cut the Countertop: Using the jigsaw, carefully cut along the inner line. Make sure to cut slowly and steadily to avoid chipping the countertop material.

Attaching the Sink

Apply Sealant: Flip the sink upside down again and apply a continuous bead of silicone sealant around the underside of the sink’s lip.

Position the Sink: Lower the sink into the countertop cutout, ensuring it fits snugly. Press down firmly to create a watertight seal with the silicone.

Secure the Sink: From underneath the countertop, attach the provided mounting clips to secure the sink in place. Tighten the screws gradually to ensure even pressure around the sink’s perimeter.

Ensuring a Proper Seal

Apply Plumber’s Putty: Roll plumber’s putty into a thin rope and apply it around the drain opening. Press the drain flange into the putty and tighten the nut from beneath to create a waterproof seal.

Connect Plumbing: Reattach the plumbing connections, including the P-trap and water supply lines. Ensure all connections are tight to prevent leaks.


Installing a Horow top mount sink is a straightforward process that can transform your kitchen. By following these steps, you can achieve a professional installation that enhances both the functionality and look of your space. Horow’s top mount sinks offer durability and style, making them a valuable addition to any kitchen. Enjoy your new sink and the benefits it brings to your daily kitchen tasks.
