How to Install Undermount Kitchen Sink

Undoubtedly, improper installation of your undermount kitchen sinks cannot be underrated. Surely, a poorly installed system can even affect the best quality countertop in your kitchen. With that, we shall learn how you install a undermount kitchen sink in this article. Prominently, Kitchen sinks are quite heavy to install straight to the concrete. Therefore, a clear arrangement has to be made.

The installation scheme

It is essential to install an undermount kitchen sink prior to setting down the countertop slabs. Usually, after establishing the countertop slabs, you will not be in a position to fix the sink. Consequently, you will not suitably seal between the underside of the countertop and the sink.

Install the sink supports

Basically, there are three methods you can use to install sink supports.

The 3 kinds of sink support for your kitchen

If you have a concrete countertop, ensure that the concrete does not bear the pressure of the sink. Rather, establish support using the plywood and the cabinet frame. Conveniently, these two will help to withstand the weight of your kitchen sink.

The commercial Bracket

The first sort of support is the commercial sink bracket marketed by the various granite supply firms. Typically, the commercial Bracket is made to be fixed onto the kitchen's cabinet frame. Carefully, follow the manufacturer's directions to ensure everything is perfect.

The custom Wood Frame

The second sort of support is a created wood frame that attaches to the walls of the kitchen cabinet. In this case, the frame supports or holds the sink by its flanges. Conveniently, leave some wiggle area between the cradle and the sink bowl. This is for the sake of aligning the sink with your countertop opening.

The custom Plywood Shelf

Another kind of support is a layer of the 0.75 inches plywood shelf. Suitably, trim this to fit in the cabinet. Normally, the plywood has an opening cut into it that your undermount sink falls into. Actually, the opening in the plywood needs to be large enough to permit the sink to be moved. The sink must align with the opening in the countertop. Seldom, it is helpful to rout a rout around over along the inner edge of the slot.

Additionally, it is necessary to cut openings for all the faucet and plumbing attachments that attach to the countertop. Always, the opening in the plywood needs to be large. Preferably, it should be large enough to permit tools to access the plumbing and faucet hardware.

Fix the sink onto the support frame of your cabinet

Always, be careful while fixing the sink onto the support frame of the cabinet. Actually, there have been some cases that people end up injuring themselves as they do this.  

Apply a reasonable bead of caulk about the top of the flange of the sink.

Install the adjoining countertop slabs above the sink.

Properly sandwich it between the cabinet frame and the countertop.

What is the importance of caulking as a process of how to install undermount kitchen sink?

Most importantly, create a watertight fastener between the sink and the base of the countertop. Even as you apply the silicone caulk right along the flange, ensure that you do it with care. Always, it should be adequate to form a watertight seal. However, it should not be too much that it becomes untidy.

Remember, bare concrete will always react with silicone to give a dirty-looking, oatmeal-like density. Consequently, this will flow out of the sink connection points. Accordingly, you should seal the base of your sink openings. This is important so that the sealed concrete only touches the silicone.

This way, the installation process will take short time as much as possible. If possible, you can do some basic things by yourself as you wait for your plumber. These may include dusting the base of the stone top and assembling the necessary tools and equipment.
