Make sure the surroundings of the sink are cooled  before mounting  the 

faucet  to the sink after drilling and remove all sharp edges. 

Step 3

Step 4

Determine desired  location  for  the faucet on your sink and place a 

piece of masking tape over where the hole is  to be drilled.  Mark the 

center of the hole on the tape.

Step 1

Using a variable speed drill set on the slowest speed, drill a 

1

/

8

“ pilot 

hole through both porcelain and metal casing of sink at the marked 

center of  the desired location. Use lubricating oil or liquid soap to keep 

the drill bit  cool (If drill bit gets hot it may cause the porcelain to crack 

or chip). 

Using a 1/2” Drill Bit, proceed to drill the larger hole.  Keep drill speed 

on  the  slowest speed and use lubricating oil or liquid soap to keep the 

hole saw cool during cutting.

Step 2

Drill a Hole for the Faucet in a Porcelain Sink

Punch a Hole for the Faucet in a Stainless Steel Sink   

Drill a 

¼

” pilot hole.  Use a 

1

/

2

” Hole Punch and an adjustable wrench 

to punch the hole in the sink. 

Step 5

The faucet can now be installed.

If  mounting faucet to a Stainless Steel Sink  you will need a 1/2” 
Hole Punch.   The  faucet opening should be centered between  the 
back splash and the edge of the sink, ideally on the same side as 
the vertical drain pipe.

Note:

Note:

Most sinks are pre drilled with 1 ½” or 1 ¼” diameter hole that you can use for your   
faucet. (If you are already using it for a sprayer or soap  dispenser, see step 1)

Porcelain sinks are extremely hard and can crack or chip easily.  
Use extreme caution when drilling.  Watts Premier accepts no responsibility for 
damage resulting from the installation of faucet.  
Diamond tip drill bit is recommended for drilling in porcelain.
