What is a Flush Mount Farmhouse Sink?

A flush mount farmhouse sink, also known as an apron front sink, is a type of sink that sits level with your countertop. This design not only gives your kitchen a seamless look but also makes cleaning a breeze as crumbs can be swept directly into the sink. Plus, with its deep basin, you’ll have plenty of room for washing large pots and pans.

Types of Farmhouse Sinks

Farmhouse sinks come in various styles, each with its unique installation process. Let’s take a look at the three main types:

Drop-in Farmhouse Sinks

Drop-in farmhouse sinks, also known as top-mount or self-rimming sinks, are designed to sit on top of the countertop. The sink’s rim, which extends over the countertop, supports its weight. This type of sink is relatively easy to install and doesn’t require internal support within the cabinet.

Undermount Farmhouse Sinks

Unlike drop-in sinks, under-mount farmhouse sinks are installed beneath the countertop, providing a sleek and seamless look. However, they require additional support due to their weight, especially when filled with dishes or water.

Flush-mount Farmhouse Sinks

Flush-mount farmhouse sinks are installed so that the sink’s front edge is flush with the countertop. This type of installation requires precise measurements and cutting of the countertop, but the result is a clean, streamlined look that many homeowners love.

Can You Install a Farmhouse Sink on an Existing Countertop?

Yes, you can install a farmhouse sink in an existing countertop, but it requires careful planning, precise measurements, and some carpentry skills. The process involves cutting out a portion of the countertop and potentially modifying the cabinet below to accommodate the sink’s size and weight.

Things to Consider Before Installing a Farmhouse Sink

Before you dive into the installation process, there are a few factors you need to consider:

Weight of the Sink

Farmhouse sinks are typically heavier than standard sinks, especially those made from fireclay or cast iron. Your existing countertop and cabinet must be able to support this weight. In some cases, you may need to reinforce your cabinet for added support.


Accurate measurements are crucial when installing a farmhouse sink. You’ll need to measure not only the sink but also your cabinet and countertop to ensure a proper fit. Remember, it’s always better to measure twice and cut once!

Step-by-Step Guide to Installing a Flush Mount Farmhouse Sink

Now that we’ve covered the basics, let’s dive into the step-by-step process of installing a flush-mount farmhouse sink.

Preparing for Installation

Before you start, gather all the necessary tools and materials. You’ll need a jigsaw or circular saw to cut the countertop, a drill for creating pilot holes, a level to ensure the sink is straight, and silicone sealant to create a watertight seal around the sink.

Cutting the Countertop

After marking the cut lines on your countertop, carefully cut along these lines with your saw. Remember to protect your eyes with safety goggles and keep your hands steady to avoid any mishaps.

Installing the Sink

Once the countertop is cut, you can place the sink into the opening. Make sure it fits snugly and sits level with the countertop. Then, connect the plumbing, ensuring all connections are tight to prevent leaks.

Post-Installation Steps

After the sink is installed, apply a bead of silicone sealant around the edges to create a watertight seal. Then, check for any issues such as leaks or misalignment.

Installing a Farmhouse Sink in Different Types of Countertops

The installation process can vary depending on the type of countertop you have. Let’s explore how to install a farmhouse sink with granite and laminate countertops.

Installation in Granite Countertops

Granite countertops are durable and can support the weight of a farmhouse sink. However, cutting granite requires special tools and skills. It’s often best to hire a professional to avoid damaging this expensive material.

Installation in Laminate Countertops

Laminate countertops are more forgiving when it comes to cutting, but they’re also less durable than granite. You’ll need to be extra careful to avoid chipping or cracking the laminate during installation.

Cost of Installing a Farmhouse Sink

The cost of installing a farmhouse sink can vary widely, depending on the type of sink, the modifications needed, and whether you hire a professional or do it yourself. On average, you can expect to spend between $400 and $1,000 for the sink and installation.

Common Challenges and Solutions When Installing a Farmhouse Sink

Installing a farmhouse sink can come with its share of challenges. Here are some common issues and how to solve them:

  • Misalignment: If the sink is not level, it can lead to drainage issues. Use a level during installation to ensure the sink is straight.
  • Leaks: Leaks can occur if the plumbing connections are not tight. Double-check all connections and use the plumber’s tape for a watertight seal.
  • Damage to Countertop: Cutting the countertop can lead to chips or cracks, especially with delicate materials like granite or laminate. Use a sharp, high-quality saw and cut slowly and carefully.


Installing a flush-mount farmhouse sink can be a challenging yet rewarding DIY project. With careful planning, precise measurements, and a bit of elbow grease, you can transform your kitchen with this charming and functional feature.
