A friend is remodeling his bathroom. He has one of those cultured marble
vanity tops which still looks like new. The bottom of it is stamped
2008. so its 10 years old. He was going to throw it in the trash, but I
measured it and it will fit the vanity cabinet in my bathroom, except
it's about 5" too long. I told him I'll take it off his hands.

I have been wanting to replace my counter top anyhow, because it's
formica on plywood and the formica is coming loose and buckling.

So my friend pulled it off his counter and when he set it down against
the floor, the corner of the backsplash cracked off. It's a clean crack,
so I could epoxy it back on and it would probably not even be noticable.

However, that top is still too long, and I dont intend to replace the
cabinet. The cabinet on my friends vanity is junk, particle board and is
falling apart at it's base. Even if he did have a good cabinet, it would
be too close to my toilet. I need to stick to the size I have now.

So, I'm wondering if I can saw off that cultured marble top? Not only
will it fit my cabinet, but I'll be sawing off that cracked corner.
Since my counter top is in a corner, the sawed off part will be against
the wall, so it wont be seen. A little tub caulk will conceal any
imperfections in my cut if I dont get it precise.

Yea, my sink wont be exactly centered, but I'm not too worried about
that.

Anyhow, has anyone ever cut one of them? Do I use a concrete blade in my
circular saw, or what? (I'll have to cut it from the bottom side because
of the backsplash. I am a little concerned about it cracking off
irregularly when I get near the end of the cut, because that corner
cracked from just bumping against a wooden floor, so that material has
to be fairly weak. (Does that stuff get weak and brittle from time?).

I'm willing to try cutting it. If it breaks I am not out any money. But
I'd like to learn the best way to cut it, and with any luck, it will
work out for me. -Thanks-

You might be able to do it with an abrasive masonry blade but I know a
diamond blade works. Clamp a board on it as a guide and go slow.
