How do you attach an undermount bathroom sink to granite?
For most bathroom undermount sinks, all that is needed to mount the sink to the granite is a silicone adhesive. Squeeze a very thin line around the sink cutout on the underside of the granite. The weight of the sink will compress the adhesive slightly, making it spread out, so a thin line is all that is needed.
What adhesive is used for undermount sink?

Do you need clips for undermount sinks?
Do not worry! It is possible to install undermount sink without clips or mounting hardware. When you are missing the clips to install your sink, you can avoid drilling the hardware mounting holes in your granite. In that case, you can use silicone adhesive and epoxy to install the sink on your kitchen countertop.
Is Silicone enough to hold an undermount sink?
Most undermount sink manufacturers recommend that you use pure, 100-percent silicone sealant for undermount sink installation. Silicone sealants are designed for resilient flexibility and have good adhesive properties. If an ordinary caulk was used to seal the sink, it likely will fail quickly.
