Drainage Grooves in Granite
Posted in Answers to Granite Questions..., Installation Issues, Other Topics on November 30th, 2007I recall discussing drainage grooves in the
granite to drain into the side of an undermount sink, at my first meeting with the fabricator. Now, at fabrication, he tells me they can not do this.
Frankly, I would have picked a different countertop material if he had made this clear when I was choosing granite over other options. I am quite sure we discussed this on our first run though, and before I got deeper into the process of picking the slabs and etc. Similarly, I have full bullnose on most countertops in my house. At the same early meeting, I asked for the same edge on the granite, but a 1/2 bullnose ended up in the bid. The edge detail is fairly easy to change, but this issue of the grooves is more difficult.Am I asking for a truly non-standard item, or is this fabricator just not familiar with the process and unwilling to add a new service “just” for me?
I like the fabricator very much. He & his staff have been very helpful, but this has kinda set things back. We did discuss a lot of issues at that first meeting, but this has been on my list of basic wants for this kitchen upgrade for so long, that I am really surprised he could have missed it.
What should I expect?
Am I stuck with an ugly drainboard on the countertop, on top of my beautiful granite?

Hello Eileen,
I must admit this is the first time I have been asked about this so I appreciate the interesting new issue you are facing. I am sorry for your trouble but the request you are asking of the granite provider is not very normal.
What you are describing is doable but extremely difficult and requires the right CNC machinery to perform the grooving and polishing work accurately. If the fabricator does not have a CNC machine with the right tooling, then it can not be done without an incredible amount of saw and hand work. In addition the polishing of the groves would be extremely time-consuming.
Most likely, you would not be happy with the result in the long run. The grooves would be prime mildew catchers and hard to keep clean. I can see your point that if you don’t have a dishwasher, you are stuck with a tile drying rack but that is what is most common.
Again, it can be done but it is expensive and there is that mildew issue that I mentioned. You could research other granite companies in your area to see what they can do. A list is available on www.GraniteStock.com.
Regarding the bullnose issue, fabricators rarely charge more for a full 1.5″ bullnose over a 1/2″ bullnose. It sounds like there was just a verbal mix-up and I hope you are being treated fairly about this.
I am very sorry about the late reply. Please send any follow-up questions that I can help you with.
