epoxyed undermount sinks

[fauxthis08]

I have 2 undermount sinks that have been installed with epoxy to granite countertops ,and want to change these out without destroying the granite tops any ideas?

I believe you would need a diamond blade cutter and run it under the counter and at the top rim of the sink, using a vertical 3 3/4" cutter.

if the sink is cast iron would you still reccomend this approach?and thank you for the reply thats a great idea

You are not cutting the cast iron, you are cutting directly between the granite and the cast iron. You just want a smooth surface cut so you can attach a new sink, correct? Keep in mind that most granite counters also drill holes under the counter and hold the sink with expanding lead plugs. Does your existing sink have these plugs?

I dont think so these are only 12 inch vanity sinks and I dont recall seeing anything like that,Thanks again

Many sinks are simply set on a plywood base, then the granite is layed on top, with silicone in the gap between the sinks and the counter. Please confirm so I don't offer incorrect information.

thanks again for your input,The granite tops are set onto the cabinets without plywood,and are defenitely not fastened with silicone.I think your Idea is great and will proceed.I do enough tile work that I am very comfortable with this tool.

hey ,here are the pictures of the epoxyied under mount sinks that I was able to cut out.Your advice was perfect 10 minutes apiece with a 4.25 dry diamond blade and a few gentle taps with a hammer on my putty knife and those babies were out of there.The sinks turned out to be porcelin which made it that much easier didnt lose more than a 1/16 of granite anywhere. thanks again for the advice
