Found on craigslist for $50 almost a couple years ago, I knew this marble slab which had a former life as a table top would make a beautiful bathroom vanity top …. and then it sat in our basement for nearly two years until just recently.
Countless hours spent googling “how to cut marble slabs” and perusing DIY chat rooms didn’t reveal much about cutting marble (although there seemed to be a wealth of information on how to cut granite or cultured marble). I started to think that maybe this wasn’t a DIY project and called around to local countertop fabrication shops only to find out that what they wanted to cut it was nearly 6X the amount I paid for the marble or that they would only cut stone purchased from them directly - so back to the DIY route I went.
I figured if Michelangelo could carve David out of marble there had to be a way I could employ the modern technology at my disposal to shape my marble slab into a much less intricate vanity top. So here’s the process that worked for me and a few tips for other DIYers looking to take on something similar.
Step 1: Setup and Layout
Our setup consisted of a couple of sawhorses with some sandbags set on top and the marble slab balanced onto of the sandbags. The sandbags are there to absorb the vibrations of the cutting tools and avoid cracking. The layout was done with some basic measuring tools, a permanent marker, and painters tape. I made my cutting marks directly on the painters tape and left it on the marble as we cut it to help avoid chipping the edges.
Oh and for those of you who aren't familiar with how our vanity looked before this whole project started check out this post.
