How to Install a Copper Farmhouse Sink

Congratulations! You have purchased your genuine hand hammered artisan crafted SoLuna copper farmhouse sink and are now ready for the installation. There are a few considerations when installing your copper farm sink.

First and foremost, hand-crafted copper sinks can have slight variations in dimension. So you will want to make sure that you have your sink in hand prior to cutting existing cabinetry or counter-top – or finalizing your cabinet order if you are starting from scratch. Secondly, we only recommend an undermount installation for our SoLuna copper farmhouse or apron sinks, not a flush mount or built-up type installation. Here is what an under-mount installation looks like:

Step 1

Are you starting with new cabinets or retrofitting into an existing cabinet?  If you are building or remodeling a kitchen from the bottom up, you will be able to choose cabinets specifically made for apron sinks. They will have a cutout where the false drawer section below a sink would normally be. The cabinet manufacturer will be able to adapt to the exact dimensions of your copper farmhouse sink.  If you are retrofitting, you will simply need to cut out the false drawer section to the height of the apron.

Step 2

Make an exact template of the top of your copper sink in order to make a precise cutout of the counter material.  For an undermount installation, the cutout should be approximately 1/4 inch narrower than the sink width, side-to-side. The front-to-back measurement of the cutout is from the apron sides as the apron front will project out from the cabinet between 1” – 3” depending on the model (this information is on the product detail page).  The front-to-back cut-out of the countertop should accommodate this measurement, minus a 1/4 of an inch for overlap.

Step 3

If the cabinets are being special ordered using your dimensions, the cabinet maker will add supports inside the cabinet to support the sink at the right height (using your measurements).  If you are retrofitting an existing cabinet, it will be necessary to add these supports yourself.  Although our copper farm sinks are made from the thick 14-gauge copper, they are not as heavy as cast iron or stone sinks. However, you will want to keep in mind that you may be filling the sink with water for cleaning, so you will want to accommodate for the sink and water (usually a total of 200 – 250 lbs) of support.  This can be done with 2x4 supports on the back, front and sides of the cabinet.  The supports should be positioned so that when installed, the sink is flush and level with the top of the cabinet. Use shims, if needed, to level the sink.

Step 4

Seal around the gaps and overlaps with a clear silicone sealant. Wipe away any excess sealant.

Step 5

Install plumbing (drain flanges, drains, disposals and P-traps) and faucet according to instructions. For additional care and maintenance, please see our Copper Sink Maintenance Page!
