How do you cut curves on marble tile? I have a rounded edge fire place to get a round.

Hi Roger,
Can you post a picture of what you mean, please? From your description, I'm thinking that you've got a hearth that has a curved edge? Is that correct? Or do you have an arched fireplace niche that you are installing tile into?

ok it looks alot like the tub image on the screen. I just need to know what kind of tool to use to cut a curved or rounded edge on marble.

Hi Roger, Welcome. :)

Convex cuts are easier than concave cuts. You make both on the wet saw by making a series of very short cuts for convex radii and notches into the tile for the concave. A grinder/-sander is a must.

What you are proposing is not exactly an entry level operation. Takes some years to get the hang of working with stone. ;)

Thanks for the help John. Most of the house is already tiled with in ceramic, but this will be the first stone tile Ive put in. Thanks again

My process for the pictured tub was as follows:
Lay up face tile to finished height.
Dry set deck tile with joints
trace radius on underside of tile with pencil; number pieces to keep them organized AND remind you which pieces to keep and what is the waste :D
using wet saw, cut down radius pieces just along the outside of the traced line
using a variable-speed grinder and polishing pads of progressively finer grit, shape and polish the radius; be very careful not to over polish and remove so much material that the piece no longer fits
install tile
smile :D
Best of luck,
PS: I've tried to polish curves like this in place but too often I've run the risk of damaging surrounding pieces and I prefer this method instead. And doing the polishing away from where you plan on working keeps your working area clean and relatively dustless.
