How to Install a Apron Sink?

An apron-front sink brings a striking aesthetic and functional upgrade to your kitchen. With its exposed front panel and large basin, it enables closer access and often accommodates large cookware easily. Below is a comprehensive walk-through of how to install one in a kitchen cabinet environment.

1. Planning and Preparation

Before starting the physical installation, carry out the following tasks:

• Measure the cabinet opening: note the width, depth and height of the base cabinet where the sink will sit. Some Apron Sinks demand a cabinet that is wider or deeper than standard.

• Verify the sink’s weight and support needs: Many apron-front sinks (especially those made of fireclay, cast iron or stone) are significantly heavier than typical drop-in models and will require additional framing support.

• Inspect the space for plumbing clearance: Check supply lines, drain trap, disposal, and ensure the apron front of the sink will not obstruct cabinet doors or drawers.

• Choose your sink and supplier: For example, AMEIAO offers a wide range of Kitchen Sinks, including apron-front models, providing high-end hardware solutions.

• Gather tools and materials: At minimum you’ll need a level, tape measure, drill, jigsaw or oscillating saw, 2×4 lumber for support framing, shims, sealant (silicone) and plumber’s putty.

2. Remove the Old Sink and Countertop (if applicable)

Remove the existing sink and possibly the countertop to make way for the new installation:

• Shut off the water supply under the sink (both hot and cold) and disconnect the water lines.

• Remove the drain assembly and P-trap, capturing any residual water in a bucket.

• Remove the screws and adhesive securing the countertop to the cabinets if the countertop must be removed.

• Clear out the base cabinet (drawers, doors off if needed) so you have full access to the interior.

3. Build the Supporting Frame

Because the front of the sink will extend beyond the cabinet face and the sink may be heavy, you need a robust support structure. In brief:

• Construct horizontal ledger boards (e.g., 2×4) along the sides and back of the cabinet opening, at the correct height so the top of the sink will sit flush (or just under) the countertop.

• Install vertical braces if required to carry the load, especially for heavy sinks.

• Verify the support frame is level and stable.

• Ensure the width of the cabinet interior is appropriate to the sink width noted in manufacturer specs. For many models the cabinet interior width should exceed the sink width by about 3″ (7.6 cm).

4. Modify the Cabinet Front / Cutout for Apron

The characteristic apron front will extend past the cabinet face, so you may need to modify the cabinet opening:

• Remove any false drawer front beneath the sink cabinet; these are often not needed once the apron replaces them.

• Mark the cutout where the sink apron will be visible. A template may help with accuracy.

• Use a jigsaw or oscillating saw (with masking tape on the face to prevent splintering) and cut the panel to match the apron height plus a small clearance (e.g., ⅛″ or so) to allow sealant.

• Sand any rough edges and ensure the modified opening is clean and ready.

5. Position and Install the Sink

With support and cabinet front prepared, set the sink:

• Dry fit the sink into the framing to ensure everything aligns: apron front, basin position, plumbing clearance.

• Check that the top edge of the sink is flush or just under the countertop level (depending on your installation preference). Use a level and adjust with shims if needed.

• Apply a bead of silicone sealant around the top rim of the sink (where it contacts the countertop or cabinet framing) as required.

• Set the sink into position and press firmly; remove excess sealant immediately.

• Anchor the sink if the manufacturer requires fasteners, though many apron models simply rest on the internal frame.

6. Install Countertop and Finish Cabinet Front

After the sink is set, proceed with countertop and cabinet finishing:

• If countertop was removed, reinstall or replace the countertop now, ensuring the sink rim is sealed and integrated.

• Apply sealant around the perimeter of the sink rim at the countertop interface to prevent water seepage.

• Re-install or modify cabinet doors/trim around the new opening to align with the sink’s apron aesthetic. Trimming or replacing the drawer front may be necessary.

• Clean all surfaces, wipe away sealant residue, and allow curing time as recommended.

7. Reconnect Plumbing and Final Checks

Finish the plumbing steps and ensure the installation is watertight and secure:

• Reconnect water supply lines, drain trap, garbage disposal (if applicable) following local plumbing codes.

• Apply plumber’s putty around the basket strainer or flange before tightening; hand tighten nuts—over-tightening may crack certain sink materials.

• Turn on water, check for leaks at all connections, and inspect cabinet interior for any signs of dripping.

• Confirm the sink is level, stable, and the apron front aligns flush with the cabinet face or design reveal as intended.

Conclusion

Installing an apron-front sink enhances both the visual appeal and practicality of a kitchen.
