How to Install a Farmhouse Apron Sink

There aren’t many remodeling projects that work comfortably in both traditional and contemporary interiors. It’s hard to think of any bath fixtures that could do this. The same is true of most furniture, wallpaper, light fixtures, cabinets and even appliances. So, when you find something like a farmhouse apron sink that can look good in just about any kitchen, it’s worth taking a closer look.

These fixtures are firmly rooted in the past because they echo designs from decades ago. But they also have contemporary grace notes due to their simple, unadorned designs, and are very popular with today’s kitchen designers.

Farmhouse sinks are made with both single and double bowls.

Though most farmhouse sinks have single bowls, double bowls are also widely available. Some buyers don’t want to make the change to single bowl models because they are used to how these sinks work. Others just prefer the look of a double bowl sink. Although both types function differently, the installation of both is basically the same.

Although you can find farmhouse units that drop in over your countertop, the under-mount approach is more common. This means that if you have laminate counters, you should pick one of the drop-in models that can cover the cut edges of your sink cutout hole. These sinks look like under-mount models because they have the same front aprons. They do not, however, have one of the great features of a typical farmhouse sink—the ability to wipe counter debris directly into the sink without hitting a sink lip. If you plan to install new counters, then the under-mount approach is preferred.

Sink Cabinet Retrofits

Fortunately, these sinks are designed to work in existing sink cabinets. They do require modifications, but none are very difficult. The first step is to remove the existing sink, then make a sink access-notch in the face frame just above the doors. Although this panel can sometimes look like a drawer, it is a false front. A drawer couldn’t work because the sink occupies the space that a drawer would require. Occasionally these panels operate, when they are hinged to tip down, so sponges can be stored in a small tray behind the panel. However, this feature is eliminated when the new sink is installed.

removing existing kitchen sink

To remove an existing sink, first cut the old caulk around the perimeter of the sink with a sharp utility knife. Then carefully pry up the sink using a pry bar. Put a rag under the prying end of the bar to prevent damage to the counter. Once the sink seal is broken, lift the sink up and out of the opening.

 

Most sink cabinets are 36 inches wide, but some are 30 inches wide. Farmhouse sinks are available in both sizes, so pick out a model that will fit your cabinet. Next, take out the template that comes with the sink and read the directions about how to use it. The template will explain how to support the sink and how to cut the counter next to it, if required.

For under-mount installations, the sink should be supported from below. (When full of water, these sinks can become very heavy.) This means using a drill to screw 2×4 support cleats to both cabinets walls and the back of the cabinet, too, if it leaves enough room for the plumbing connections. The template will explain exactly where these cleats should be located to support the sink you have. Make sure to use screws that go only through the cleat and the side of the cabinet. Don’t use screws that are so long that they would interfere with the operation of a drawer in a nearby cabinet.

The template also explains the location and the size of cuts required in the face frame. To make these cuts, you’ll need a variable jig saw. In most cases, there should be enough room to make the cuts without interfering with the doors underneath. But if this happens to you, you’ll have to install new, shorter doors and add a filler block between the new doors and the bottom of the new sink. Use blue painter’s tape to cover up the cabinet face where the notch cuts fall. This will reduce the splintering from the cut and protect the surface from scratches caused by a rough saw foot. When working with a jig saw, be sure to wear protective eye gear and work gloves.

Placing the Sink

Before sliding the sink into place, run a bead of silicone caulk around the face frame cutout and along the top of the support cleats. Get some help to lift the sink and lower it into place from above. Locate the sink so the apron sticks out about a half-inch from the front of the cabinet. Next, push the sink against the cabinet and wipe away any caulk squeeze-out from around the sink. Lastly, add some silicone caulk to the top edges of the sink, then install the countertops over the sink. Again, be sure to wipe away any squeeze-out.

Plumbing Connections

Because these sinks have big, deep bowls, they frequently have single drain openings. However, the sinks they replace are almost always double-bowl units with two drain openings. This means that the waste plumbing components need altering. If you’re not comfortable working with plumbing, or run into any questions as you’re working, call a licensed plumber.

The first step is to install a drain assembly in the drain hole, according to the directions that come with this hardware. This assembly must be connected to the sink trap that’s already in place. How this is done is dependent on the existing conditions, but most often, you first install a disposer unit to the bottom of the drain assembly. Next, remove the trap from the existing system, then install it on the pipe coming out of the disposer’s side. Finish up by positioning the trap so the drain side is facing toward the waste pipe in the wall. To make this work, the extension pipe from the trap to the drain pipe in the wall needs to be cut to size.

If your new sink has two drain holes, one should be devoted to a food waste disposer and the other to draining away waste water. Typically, the two are joined above the trap, then the trap is joined to the waste pipe opening in the wall. If the sink has a single opening, install the disposer between the drain fitting and the trap. Adjust the length of the extension tube to reach the wall.

The water supply lines usually need alterations too, because typically when a sink is replaced, the faucet is replaced, too. To do this, first install the faucet (and typically a spray hose on a kitchen sink), then measure the distance from the bottom of the faucet to the water supply valves and install new supply tubes from these valves to the hot and cold sides of the faucet.

Finally, test for leaks, and adjust the plumbing where needed. If no leaks appear, you’re done!

How to Install a Bathroom Sink

Instructions showing you how to install a bathroom sink vary according to the type of sink. This article will point you to the illustrated step-by-step techniques you need.[GARD align=”right”]

Installing a bathroom sink (also called lavatory or “lav”) can be a relatively easy do-it-yourself job if you have a few basic home improvement skills and tools.

Some types of sinks, such as pedestal sinks and console sinks are essentially just fastened to the wall or floor and then hooked-up to the plumbing. Other types require a bit of cabinetry or woodworking knowledge because you often have to mark and cut into the countertop.

How to Install a Kitchen Sink

Want to install a kitchen sink? This expert guide will take you through the process step-by-step. Helpful illustrations show details.

The kitchen sink is an essential element of any household. Food is prepared, dishes are washed, flower vases are filled, and food is disposed of in the kitchen sink. The kitchen sink can be installed above the counter, below the counter, or even as a seamless part of the counter itself.

To many homeowners, installing a kitchen sink seems like a daunting task, but the fact is, if you can trace around a template and cut out a hole, you can install a kitchen sink.[GARD align=”left”]

You do want to make sure your new sink fits your countertop and the cabinet below it, so measure the width and depth of your lower cabinets before making a purchase.

Generally, a sink up to 22 inches deep (from front to back) will fit in a standard 24-inch-deep cabinet if you have no backsplash; if you do have a backsplash, your countertop will only take a sink up to 20 1/2 inches deep. Of course, your options will increase if you are also changing your cabinetry and countertop.

1: Outline sink template on the countertop

Install a Kitchen Sink: Step-by-Step

To install a counter-top kitchen sink, follow the directions below:

1The first step when installing a new sink is to properly site the opening. Most sink manufacturers provide a template. Position the template so it is centered on the sink cabinet and is at least 1 1/2 inches back from the countertop’s front edge. If your countertop is deeper than 24 inches, place it farther back, but not more than 4 inches. Tape the template in place, then outline it with a marker.

2. Use a saber saw to cut out the template area

2After marking the opening, remove the template and drill a 3/8-inch-diameter hole in each corner. Insert a saber-saw blade in one of the holes and start cutting along the inside of the line. To prevent the cutout from snapping off and falling through as you complete the cuts, first screw a scrap of wood from front to back on the top of the cutout long enough so it spans the opening, plus a couple of inches. When you’ve finished, simply lift the cutout from the template.

3. Seal the perimeter of the sink

 

3Install the faucet (see How to Install a Kitchen Faucet for instructions) and the sink strainers. (Doing this when you’ve got full access to the sink will be much easier than fitting the pieces in from below after the sink is installed.) Next, to create a watertight seal between the sink and the countertop, apply a bead of silicone caulk or plumber’s putty around the entire perimeter of the underside of the sink’s lip.

 

4. Carefully set the sink into position

4Carefully flip the sink over and insert into the opening, taking care not to disturb the caulk or putty. Now install the kitchen sink. If your sink is heavy, get help lifting and installing it; also consider placing a couple of scraps of wood near the edge of the opening to support the sink and protect your fingers as you drop it into position.

 

5. Tighten mounting clips

 

5Most sinks are pulled down tight against the countertop with special mounting clips that hook onto the lip on the underside of the sink and are tightened with a screwdriver or nutdriver. Follow the manufacturer’s directions for spacing these clips. Tightening the mounting clips may cause the caulk or putty to squeeze out from under the sink lip, so remove this excess with a clean, soft rag.

 

6. Connect the P-trap and turn on the water

6To complete the project, first connect the P-trap. Join the faucet lines to the hot and cold supply lines with flexible supply tubes and connect the strainers to the waste line. Turn the water on at the shut-off valves, remove the aerator from the faucet, then turn on the water from the faucet to flush the system. Reinstall the aerator after you’ve run the water for a minute or so.

How to Install a Wall-Mounted Sink

bath-sink-wall-finish-sun

[GARD align=”left”]Wall-mounted sinks are either hung on a metal bracket that is attached to the wall’s framing or bolted directly to the framing (as shown here).

These sinks come with manufacturer’s installation instructions, which should be followed closely.

To provide the proper support for a wall-mounted sink, it’s usually necessary to remove a small section of drywall so you can access the wall studs and attach blocking between them. Click for more about How to Open Up a Wall.

Determine where support will be needed, based on the sink’s measurements and mounting height (typically 30 inches above the floor). Remove drywall in that area and install 2-by-6 or 2-by-8 blocking between wall studs.

Drill holes for screws and fasteners.

Drill holes for screws and fasteners.

Toenail the blocking to the studs with 3 1/2-inch galvanized common nails. Then repair the drywall.

1Position the mounting plate or sink on the wall and mark the wall through the holes in the plate or sink. Drill pilot holes for lag screws or other fasteners supplied by the manufacturer; if the wall is tile, use a masonry bit.

Then install the faucet and drain and pop-up assemblies on the sink (see step 3 of Install a Countertop Sink and steps 4, 5, and 6 of How to Install a Bathroom Faucet.

Hang

Secure the sink or mounting plate to the wall.

 

2Use lag screws or other fasteners recommended by the manufacturer to secure the sink or the sink’s metal mounting plate to the blocking. After driving in the first fastener, check to make sure the sink or mounting plate is level, then drive in the other fasteners.

 

3Connect the P-trap and drain arm to the drain stub-out, then connect the two water-supply tubes to the shutoff valves.

Connect

Connect the P-trap and water supply lines.

Some wall-mounted sinks (like the one shown here) come with a trim piece that hides the plumbing lines. These typically attach directly to the wall framing with lag screws.
