Last year in Tucson, my 54 x 22 quartz vanity remnant (no splashes) was $625 for fabrication and install by a local fabricator. One kitchen designer quoted $750 for a vanity remnant. That was about 18 months ago, so figure an annual price increase and the S.F. premium and that will give you an idea. Or not.

Home Depot online has a countertop estimator that's sort of fun to use to get an idea of pricing. Plug in a S.F. HD location and it may give you a better idea. https://hdapps.homedepot.com/CtopEstimator/pages/index.html#/

Do you have the remnant or will use one the fabricator has? That could affect pricing, too.

Holy cow! I feel your pain. I mean, I really feel your pain! I had a 23" x 100" remnant from my kitchen install that I was going to use part of for a desktop in a bedroom and a small counter in my laundry room. Then the GC, who took forever to get things done on the entire project, drug his feet again by several months getting the laundry cabs installed and getting the supports in for the desk. I did check once at the fabricators to make sure they still had my piece. A month later, when I went back to get a quote for the fabrication and install of the piece, they told me they inadvertently threw my piece away when they were cleaning up their remnant area. I suspect they either sold it or broke it. Anyway, I'm now out a remnant piece for my desk and laundry room. They offered to let me have my choice of another piece, but there were no pieces that would work.

So I thought, OK, I'll just get it from HD and take a chance they can install it to my liking (nice tight fit, etc.) (Using the calculator, I thought I could get exactly what I wanted at HD for about $650.) Well, it turns out that HD sells only a minimum of 25 square feet or $1300 worth of counter. My little 12 square feet would cost $1300! So that HD calculator is good only if you're thinking of more than 25 square feet!

I guess I will have to run around to some stone yards in the heat this summer and see if I can find a remnant that will do. Now you have me wondering what the fabrication cost will be if I start from scratch! I thought I would deal with someone other than the guys who "lost" my remnant, but I may have to check back in there just so I can play on the guilt factor to keep the cost down as much as possible! They had quoted something like $500 to fabricate and install the desktop late last year. Sigh.

Do you know why this is? Your little vanity top is almost as much template, paperwork, loading, and driving as a 60SF kitchen. When I fabricated, I hated single vanity tops; they were too small to make any money on with the same level of risk.

Who are you buying the remnant from? If you are walking into a fabricator with a remnant that you picked up elsewhere it will be quite expensive as to the fact that he ain't making money in the slab and he is assuming all the risk should he mess it up.

I turned a free island into a vanity for a customer recently. She probably could have bought something new and had a selection for what it cost her.
