If you truly want a home wet bar, there needs to be a sink installed. Otherwise what you have could be called a bar or just a liquor cabinet. Having a sink completes the setup. It allows you to do all of your cleanup right there without having to take any dishes, bar mats, glasses or other bar accessories up to the kitchen for washing. Once your bar is in place and the water line and drain pipe have been extended to reach the wet bar, you can proceed with the sink installation. If you have not decided where exactly to install the sink, perhaps the position of the water lines can help to make up your mind. The flexible stainless steel hot and cold water hoses running from the line to the sink can reach, but it’s helpful if the sink is as close to the lines as possible.
Step 1: Draw Line for the Sink
Once you have decided where to install the sink, lay out the template provided with the sink. Most new sinks will come with a layout guide. If you purchased the sink used or it has no template, measure the dimensions of the outer rim of the sink. Take your straight edge and make the appropriate marks on the counter with those dimensions. It is very important that you decrease the size of the box by between ½ inch and ¾ inch on all sides. If you neglect to do this, the sink may slip right through the hole when you install it. A template will factor this in.
Step 2: Drill Hole to Get Started
Affix the paddle bit to your power drill and make a hole in one corner of the traced box. When drilling, position the bit so the end of the hole closest to the line touches it but does not go over it.
Step 3: Cut Out the Hole
At the other three corners of the drawn box, curve the lines to reflect the shape of the sink when it is set in. A curved line is easier to cut with a jigsaw. Insert the jigsaw blade into the hole you drilled and move along the line. Don’t go too fast, but be confident with the tool. You want to stay right on the line. When you reach a curved corner, slow down to stay with the line. You can always stop mid cut and start up again to get a better angle on the cut.
Step 4: Test it Out
Lower the sink into the hole to make sure the rim is supported by the countertop.
Step 5: Drain Flange
Before setting the sink into place and sealing it you want to install the drain flange. This allows to work in an upright position and not have to crawl underneath in the cramped space below the sink. You need plumber’s putty to seal the drain flange into place in the hole at the bottom of the sink. After rolling out the putty and applying it to the underside of the drain flange, press it firmly into position.
Step 6: Drain Gaskets
Now turn the sink over. Install the gaskets that come with the sink over the drain stem. Follow the manufacturer’s directions so you do them in the correct order. On top of the gaskets goes the drain stem cover followed by the locking ring. With the channel locks, tighten the ring until excess plumber’s putty oozes out. Wiping away the remnants, a water-tight seal has bee formed.
Step 7: Faucet
The faucet installation is much the same. Apply plumber’s putty around the lip and slide the stem into the designated hole on the sink. On the underside, affix the washer and nut and tighten it with your adjustable jaw wrench.
Step 8: Install the Sink
Finally it is time to seal the sink into place. On the topside of the counter around the edge of the hole, squeeze out a continuous bead of caulk sealant. Lower the sink into the hole and align its edges with the sealant. Set it down into the caulk and press down on all sides of the sink to affix it into place.
After the sealant sets up, you can wipe away the excess. Check the seal for any inconsistencies. When it looks good, you can hook up the water lines and use your wet bar sink for the first time.
