While remodeling a bathroom recently I needed to install a
bathroom countertop sink. I used a self rimming drop-in bowl as they are the
easiest bathroom countertop sink to install.
Cut hole in the Bathroom Countertop Sink
I first needed to cut out a hole in the counter top for the
bowl to sit in.
The bathroom countertop sink bowl came with a template for making the hole. I just
found the center of the countertop and positioned the template such that it was
centered over my center mark on the countertop.

I then traced around the bathroom countertop sink template. I used a little tape to
hold the template down while I traced.
I then drilled a couple of 1/4” holes so that I had a place
to insert my jigsaw and begin cutting the countertop. I then cut out the hole in
the countertop.
After cutting the hole in the countertop, I next temporarily put the bathroom
countertop sink into the hole to see how it
fit. I then removed it to assemble the faucet and drain assemblies. You don’t
want to put the bathroom countertop sink in and then have to assemble the faucet assembly, unless of course
you like to contort yourself.

Installation of Bathroom Countertop Sink Drain and faucet assembly
Once I confirmed that the bathroom countertop sink bowl would fit properly in
the hole, I then assembled the drain assembly to the bowl. I first attached the
metal drain pipe with the gasket, washers and locknut to the drain hole in the
bottom of the bowl. Note that I used a little plumbing putty around the gasket
and washer to ensure a waterproof seal.
I then installed the faucet assembly and the hot and cold supply
lines to the bathroom countertop sink bowl, using the washers and nuts supplied.

Final installation Bathroom Countertop Sink Bowl into the Countertop
With this particular bathroom countertop sink bowl it was so heavy that all I
did was apply a bead of plumbers putty underneath the lip of the bowl prior to
placing the sink bowl in the sink. I did not use any other type of mounting
mechanism. For lighter bathroom countertop sink bowls, there are mounting clips that can be used to
securely snug the bowl to the countertop.
For a finishing touch I applied a white bead of silicon
caulk around the edge of the bathroom countertop sink bowl to get a waterproof seal.
Finally I connected the faucet supply hoses to the supply
lines that protruded out of the wall and into the vanity. I then turned the
supply valves on and I was in business.
