This post shows the five steps to install a small bar sink.  

Step 1: A bar sink is usually a drop down sink. The sink sits on top of a counter top with a hole for the sink area. Fig.1 Above right shows this faucet that was assembled into the bar sink prior to placing the sink into its new home. If the sink was assembled prior to installing the faucet use a basin wrench to tightened the brass water bolts to the water lines. If your are starting from scratch, there will be a sink template in the box. Use it the template and tape it to the area on the counter where the new sink will be placed. Now use the line to cut the edges of the sink. Once the hole is in the counter place the sink inside and follow the rest of the directions.

Step 2: Fig.2 shows the flexible water connectors for hot and cold water lines were used for this job.

Step 3: Fig.3 shows the hot and cold braided water fill lines into the faucet. This sink was secured with sink clamps, use a crescent wrench to secured the bolts underneath the sink area. The sink is secured with clear silicone between the bottom of the sink lip and the counter top.

Step 4: Fig.4 shows the braided water fill lines are screwed into the stop valves. One stop valve for hot and one for cold water lines.

Step 5: Fig.5 shows the last step is to hook up the ABS drain line to the sink tail pipe. Use ABS adhesive to secure the pipes together except the sink drop down (white) pipe. Tightened the P-trap with a Channellocks® pliers and then check for leaks. If you do replace the pipe ring seals and that should do the trick. If none, now is the time to enjoy your new bar sink.
