Acrylic sinks are often preferred for bathroom sinks particularly when the sink will be mounted under a solid surface counter or bathroom vanity top.

Undermount sink solid surface countertop.

The edge lip of the sink is mounted below a solid surface countertop so the sink effectively hangs underneath the counter as opposed to sitting on top of it. Glue the metal sink mounting brackets to the underside of the top and clamp the bowl in place. Creates a continuous flow from countertop into sink. Additionally the seam between the sink and the top is bacteria stain and water resistant because it is a hardened resin like the rest of the non porous sink and countertop.

Follow the steps above but in place of the solid surface adhesive use 100 silicone often labeled silicone sealant or silicone caulk and metal sink mounting brackets. Granite and quartz sinks can be top mounted dropped in or undermounted with most counter surface materials. The edge of the countertop along the sink cutout is entirely exposed. The first step to installing a solid surface undermount sink is to turn the solid surface sheet upside down and locate the place where the sink is to be placed.

An undermount sink does have a rim but the rim is not visible because it rests up against the bottom of the counter. For this reason undermount sinks generally must be used with solid countertop materials such as solid surface natural stone or quartz.
