I am DIYing a 1/2 bath in my farmhouse style home. I plan to make the vanity out of 3x6 rough sawn lumber in a post and beam style. I have an old butcher block style counter I intend to use for the countertop. I want to place a copper vessel sink on it. Question: How high should I make the vanity? I know that counter heights are around 28" for bathroom and 36" for Kitchen. I like kitchen height, so should I measure 36" inches from the rim of the vessel and make the vanity accordingly? I also intend to use a wall mounted bridge faucet. I have read that the faucet should be about 6" above the vessel rim, so I am ok there. But what kind of framing do I need in the wall to support this plumbing? If the plumbing is in the wall, what do I need for valves under the sink, or do I not need them? Are shutoff valves required by code? This bathroom has no windows, am I required to have a fan in the room? To finish, we also intend to put up a copper ceiling. Should look intersting when done!

I am hoping you bought another top mounted sink. If no one has told you, while you can trade an undermount for a top mount the reverse isn't true. This is true for a couple of reasons. Under-mounted sinks do not always have holes for faucets while top mounted sinks generally do. That means a top mounted sink is generally MUCH smaller from front to back. So, to replace a top mounted sink with an undermounted one would leave a empty strip where the faucets USED TO BE. The granite guys don't normally finish the edges of the sink cut out AND they can leave the cut out very rough. If the blanco were a little larger that the cut out, you could try to have the granite guys come back, tidy up the edge and polish it BEFORE you install the sink. If it is the top mounted version, take the blanco out of the box. There should be a template in there or stamped on the box. It should show the cutout and the actual top edge of the sink rim. Lay the cutout on top of the kohler - carefully aligning the two front corners of the template sink rim to your actual sink. Tape down gently - remembering you might need to remove the template completely intact. On one side, match the rear corner of the template rim to your Kohler - it should be the same. Unless the Blanco uses some arcane clip system, you should be ok if the BOWL is a little smaller, but not if the rim is materially different.

mike_lee- Are you saying that you're sure the hole for the sink is not in the center? The point vithdude was making is that, if the hole in the sink was larger than the drain tailpiece you mounted into it, you could have tightened down the basket strainer off-center. If, indeed you know that the hole in the sink is manufactured off-center, then nothing is wrong, other than that you are bothered by the slight mismatch of the grate with the drain. I doubt very much that your sink is any different from all the other ones of that model. That type of sink is typically formed by giant presses where the die shapes are fixed in place and do not depend on the skill of an operator to align anything. I think the tail is wagging the dog on this: you are concerned about a relatively minor asymmetry issue that you wouldn't likely have noticed if you hadn't decided to add the grate. I still don't see that this is worth any kind of radical tear-apart.

Yes, I will have the standard 1 and half inch overhang and I will use a standard one hole faucet in the center. I understand there's a half inch difference in the counters but my question is- should that half inch make it completely out of the question or should we find a way to make it work as is? That's why I was curious as to what everyone else's measurements were. These counter tops will be our only counter tops for a long long time, so I'm really worried about installing the 16 inch sink they're wanting- It's just so small and I'm so worried I'll absolutely hate it. I've never loved the idea of a stainless steal apron front either but if we went that direction, how are they usually mounted? Would we need to build some kind of brace inside the cabinet?
