Is there anyway you can put a undermount sink in with tile??? Going to use 3/4 inch plywood and 1/4 inch backer board then tile. Everyone says no but there has to be a way. I think my biggest concern would be seeing the board around the sink. I dont think they make a sink that 100% square on the corners to where i could tile the the sides to you wouldnt see the boards.

any ideas??? Reason wanting to use undermount sink like the look plus easier to clean counter tops into the sink with out the sink ridge being there

thanks

oh also want the granite look too cheap to use solid granite

I don't have the expertise, but I would suggest that if you are going to do it, use cement board instead of plywood in the area right around the sink. Might need to do 1/4 and 1/2 inch to match the thickness though.

Horse you mount the sink between the backerboard and the tile . You will want to use a tile saw in order to trim the tile to fit nice around the edge of the sink.

Horse the undermount sink has a lip on it that sits on top of the backerbard and under the tile . I have even seen it done this way under full slabs. Check out www.diynetwork.com they have some decent videos and pics . I slipped on your heat strips will let you know monday :D . The duct on the other hand is a little trickier depending on what you want.

I have seen the 12"x12" granite tile that has the rounded edge. The edge is approx 1 1/2" thick and the tile is about 1/2" to 3/4" thick. Not sure where they got it from though.

What about 4 pieces of 1" wide X length of sink hole to form the sink opening. The granite has to be the same thickness as the backer board.

When the counter top is installed , all you should see is solid granite in the opening. You will have to epoxy the 4 strips to the counter top. The sink will also hold the 4 pieces , but the epoxy will hold.

I don't know what is hard about it....it's done all the time....it was the only mistake we made in our kitchen.....using a drop in sink vs undermount....

I assume you already have the sink.....as you will notice you have a fairly wide lip around it......and it should have holes in it.

If you put the sink on top of the backer board, then you won't have a good porous surface for the tile mud to stick to.

The second problem is that the lip will cause a slight rise in the tile because of the thickness of the lip. Unless you use a lot of mud, the rise will be obvious.

May I suggest attaching the sink to the 'bottom' of the plywood? Use plenty of screws. If you are worried about the strength....sandwhich another piece of plywood between the lip and bottom piece of plywood.

On the top side you are going to need a bull nose type of tile anyway to finish off the edge....tile with a 1" edge is common...which is about the space you have to fill (3/4" plywood + 1/4" backerboard)

Here's the link if that is the look you want.

You may also consider whether nosing is available for the tile you have (or want).

We bought a bunch of these along with our granite tile, but have since decided to go with a slab install instead.
