A: Oh boy Bill, I don't know where to start. First, thanks for reading my column, and I hope you still like me after you read my response.

Now for the tough love. Stop what you're doing right now before you get yourself and your kitchen into a lot of trouble!

I believe you have not done enough research on your kitchen project to attempt it yourself. I say this because your question states that you want to use marble "floor" tiles for your "counter" and that you want to install an "under" mount sink on "top" of your marble tiles. I could be wrong but it sounds like you may be confused about the entire job.

Most floor tiles, especially marble, may not be suitable for countertop use because of staining issues. Always check with the manufacturer of the floor tiles to see if it's recommended for countertop use.

In many cases the warranties may be voided if the tiles are used on any other surface but a floor. So, the first thing you need to do is make sure you have the right product for the job. Also, check with the manufacturer about countertop sealers that are compatible with your type of stone.

Now for the under-mount sink. It's called an under-mount because it's installed under the counter, not on top of the counter. Under-mount sinks can be attached to solid stone surface countertops before the countertop is put into place, or the sink can be built into the cabinet base and then the counter material is placed on top of the sink.

Either way, this is usually a job for the pros since the sink is not simply placed into a hole like a standard "drop in" style sink.

Don't forget, once the sink is installed then you need to hook up the faucet, drains, disposer, soap dispenser, basket strainer and dishwasher to complete the job. That involves a whole other set of rules.

My advice is to consult a local licensed contractor to help you out with this kitchen remodeling job before you cook your goose!
