There's a 6" jog in the wall for a chase meaning a 31" vanity top has to be cut to fit. I'd like to put in a cultured marble top because they are easy. Whats the best way to cut the corner off a cultured marble top?

In your case I'd use a diamond wheel in my 4 1/2" grinder to cut it nice and clean on top first. Overcut the bottom to complete the job.

Exactly
Measure twice, mark yer line clearly with a sharp point sharpie, and make a test cut away from it to see how it cuts.
Score it well, then transer yer marks to the underside and complete yer cut. Be carefull to not pass yer cut lines.

Thanks again Ben,

Finally got to the vanity issue today. Very happy with how the grinder performed.

Lucky for me it wasn't a timed event cuz I took it real slow. Definitely an outside job with the dust.

Yeah it was pretty damn near perfect. Got very minor surface chips when I had to cut again after scribing the backsplash and corner to fit in the hole. Chips were easily covered with a bead of silicone.

I only got a chip when using the under side of the wheel against the finish side of the cut With the top side it didn't chip at all. The wheel wasn't brand new so that might be the reason

Maybe the wheel was running against the grain, is why it chipped ?
Dunno

Just for future reference since this job is already done...one common method used around here for cutting cultured marble is to use a blade turned backwards in a circular saw.
