I am installing a granite vanity top with an undermounted sink in the
bathroom. The vendor said to attach the sink to the underside of the
granite top with adhesive glue. The instructions say to drill holes in the
granite and attach the sink with screws. I do not want to drill into the
granite and the adhesive method sounds like an accident waiting to happen.
Does anyone have any hands-on experience with this? thanks in advance.
all my underslung sinks are integral with the counter tops. Definitely glued
together I can see the seams. Your counter top should have some sub
structure like plywood to support the counter top. You could screw into the
Yeah, have had experience twice..Silestone countertops and stainless
undermount sink First one in old house, the countertop guys came in late on
a Friday, set the tops and the sink was "bonded" to the countertop and the
clamps were still attached. They said in 24 hours we could hook up the
plumbing. So 24 hours later we took off the clamps and I started to install
the ring that holds the garbage disposal. Was pushing on it to center it
and BOOM. the entire sink dropped out!!!! Being now Saturday and we were
way tired of not having a sink, we cleaned it up, put on silicone and built
a 2X4 structure under the sink to support it. Never had another problem.
Brand new house just completed this last november. Samn damn thing. Sink
was bonded same as before but we were "assured" that they use special glue.
Lasted about a week. Stainless undermount started to sag in the center so
we got busy with the boards again. At least this time it didn't fall out.
Point is, you may be okay with a small bathroom sink. Myself after having
this happen twice I would insist on some sort of support system or you may
find your sink down in your vanity one morning..
Just had Silestone counters and a Moen composite sink installed last
week. The sink was bounted on a 1x2 frame screwed into the cabinets
with the upper rim flush with the top of the cabinets. The rim of the
sink was loaded up with color matching silicone sealant and the
counters mounted on top.

Our countertop installer sandwiched the SS undermount sink between the
countertop and the plywood sub-base. Haven't seen a problem
