Installing your new bar sink can be fairly simple or very elaborate. It all has to do with the type of sink you purchase. If you decided to add a drop-in type sink, as long as you already have the right sized hole in the countertop, the installation is pretty simple. If you have decided on an under-mount sink, installation can be a lot trickier.
With a top-mount sink, you need a hole in the counter that the sink will drop into. This type of sink has a flange, or lip, that runs all the way around the sink and sits on top of the countertop. Because this flange overhangs the counter, the edge of the hole does not have to be finished. In fact, if the hole is ragged, no one will ever know as long as you use a top-mount sink. The sink is then fastened from below the counter with screws and small plates that hold the sink in place.
Another way to secure the sink is to use epoxy. A bead of epoxy is placed around the underside of the sink’s lip. You can also place a bead of epoxy around the edge of the sink hole. Drop the sink in the hole and make sure you have a flush seam all the way around. If part of the sink is not flush, use the brackets under the counter to pull it down and secure it. If you do have a flush seam, it means you have a very smooth and level counter surface. If this is the case, you can use just epoxy to mount the sink and may not need any screws and brackets underneath. In either case, be sure to allow the epoxy to dry for the amount of time shown on the packaging. Do not touch the sink at all during this period.
In the case of an under-mount bar sink, the job is definitely more complicated. In fact, in most cases, you will want to have a professional install your under-mount sink. If you happen to have a hole prepared in your counter matching the specifications of your sink, you can attempt the job yourself. The actual mounting of the sink is not the hard part. The difficult part is usually making and finishing the sink hole. Since the sink mounts under the cabinet, there is no flange showing on the counter. This means the countertop has to have a rounded and finished edge leading down to the sink. This is where you are very likely to need a professional.
If you happen to already have a prepared hole for your under-mount bar sink, you can install the sink yourself as long as you are a little handy. When replacing your countertop along with adding a sink, the best way to install the sink is to do it before the countertop is installed. You can epoxy the sink to the counter while the counter is upside down. After the sink has dried, you can then install the counter with the sink already attached.
If your counter is attached, you have gravity working against you. You will need to epoxy the sink and clamp it in place so the epoxy can dry. The most important part of this process is to let the epoxy dry at least as long as the manufacturer recommends. You can’t go wrong by making the epoxy dry for a longer period, but you WILL get in trouble if you do not let the epoxy set for at least the proper amount of time. The result can be a sink that feels secure but fails under the load of water and dishes. That is not a pretty sight, so be sure to let the epoxy dry.
If you handle the sink installation process correctly, you will have accomplished a couple of things. First, you will have saved money by installing your bar sink yourself. Secondly, when your guests compliment your bar sink area, you will have the satisfaction of knowing and bragging that you did it yourself!
