My new bathroom wash basin is too long and I like to cut 1-1/2" off
from both ends. If I use a circular saw, what type of saw (Numbers teeth)
should I use. I believe the basin is made of white "cement" and not
plastic
or fiberglass, with a thin top coat of transparent plastic.

Find out what it is really made from first. Wrong material and blade combo
can make a mess. In general, the more teeth the finer the cut.
