Cutting a hole in tile

Hi All, shower head pipe will fall in the center of a tile, what would be the best way to drill a hole?

With a tile drill bit. Go larger than you need so if your placement is slightly off it won't matter. The escutcheon plate will hide it.

Get a glass or ceramic drill bit. Using a center punch tap slightly to provide a starter point for the drill. Use a bit of water to cool drill as you drill hole. You can buy a diamond edged hole saw for the same purpose.

I use this one, similar to the one Norm mentioned. It gives a reservoir to hold water while you drill to keep the heat down. QEP 1-3/8 in. Diamond Hole Saw with Water Delivering System-10569Q - The Home Depot

The sticky pads stick to the tile and to the blue guide, which keeps the water in contact with the bit. It all peels off and you got a perfect hole with no burns.

What kind of tile?

Ceramic, a carbide hole saw will zip right through, porcelain will cut but it's a little harder, a diamond hole saw will work great.

Either one is not terribly expensive assuming a one time inexpensive 1" size.

Depends on what type of tile you have. Others have given options. But this goes further to the actual planning stages of the tile install. I always plan my tile so that all elements from diverter valve, to tub spout to hand held adapter so that everything falls on a grout line so there is no cutting in the middle of a tile.

Problem is with today's lust for large format tiles. Leaves little to work with as far as planning.

As an aside, I disagree with Norms suggestion to hit it with a center punch to start your pilot hole. Just asking for a cracked tile. I use a very small glass bit to start the hole and progressively get bigger. No chance of cracking a tile.

if using a glass or ceramic drill bit, without a slight tap from a punch to get past the glaze, your drill will wander all over the place. I never had cracked tile from that procedure. A very slight tap is all it takes to assure a precise location to start the drill. I've used this procedure on new and existing tiled walls and never a failure.

You will note that I said "glass bit" the smallest one I have I believe is 1/8" and is shaped like an arrow head. It does not wander when you start it, it bites immediately and begins to do its job. Would you also recommend hitting a piece of glass mosaic with a center punch? Tile, in and of itself, is pretty fragile until it is embedded in a layer of thinset.

I'm glad the procedure worked for your bathroom remodel, I just don't think it is a good recommendation to use a center punch for others who may be using a softer ceramic or like I said, glass tile.

Just goes to show there is no single "right" answer to any question, what works for one may not work for the other.
