THE STEPS
UNDERMOUNT & TOPMOUNT
MORE ON FRONT 
The installation steps provided here address all 
three mounting techniques. The diagrams show that
undermounting oers three style choices, and 
usually includes the use of clips. Topmounting 
requires the use of silicone caulking. Vessels can
be mounted on the countertop or recessed into it. 
When vessels with rounded bottoms are mounted 
above the counter, a sink ring is typically installed 
below the basin in order to stabilize it.
VESSEL RECESSED
Using the template provided, measure and cut out 
the hole.
Determine the locations for the clip brackets around 
the perimeter of the sink. Pre-drill holes for the
clips.
With denatured alcohol, clean the surfaces of the 
sink and countertop which will meet.
Topmount: Apply a bead of silicone along underside 
of the sink rim or the top perimeter edge of the 
countertop opening. Undermount: Apply similarly on 
the top of sink rim or underside of countertop.
Topmount: Carefully align the sink over the 
countertop opening and lower into position, applying 
pressure to secure a seal of the silicone against the 
countertop. Undermount: Similarly align the sink 
under the countertop.
Re-check that the sink is evenly
aligned and level.
Attach and tighten the clip brackets. 
Remove excess sealant along edges with denatured 
alcohol. 
VESSEL ABOVE COUNTER
Measure and cut a hole in the countertop matching 
the diameter of the drain pipe.
If the bowl has a curved bottom, it will require a sink 
ring. Position the ring on the counter over the drain
hole, then rest the basin on the ring. If the bowl has 
a at bottom it can be rested directly on the counter.
Install the drain. 
Measure and cut a beveled hole in the 
countertop to the diameter necessary to hold 
the sink at the desired depth, not to exceed half 
of the bowl’s height.
Rest the basin in the hole.
Install the drain.
