Are you keeping these but need more? Even if youmanaged to find the same company and product number, they will not match.

^^^^This is an important question. It will be very difficult to "match" what you have. There are different grades of Carrara marble tile sold in the U.S. Most of the Carrara marble is C/D grade - there is C grade = quite a bit more expensive.

The two tile sizes that you need are not the most common sizes which will limit your options as to where to source the tile. I actually had 3x9 Bianco Carrara tile installed in my primary bathroom shower a few years ago - the tile was sourced from Ann Sacks (I think it was a custom sized order?)

My tile was fairly expensive - I also culled out pieces that I didn't want installed + organized that tile in the order I wanted it installed on the walls. The background of my tile was pretty white - a smaller amount of it was a light gray background. The veining was varied and looked quite a bit different than your Carrara tile. The veins were "crisper" = not smudged looking (and had a few different styles/patterns). Some tiles had more spots than vein lines - none of them were completely without veins.

My tile was real Carrara marble = source of origin was Italy. There is a lot of "Carrara" tile offered today that isn't from Italy (which means it isn't Carrara marble). I believe a lot of it is from China - and some from Turkey.

Below is an example of C/D Carrara tile from one vendor with a large C/D Carrara tile from a different vendor in the background:

Here are larger Carrara marble tiles - nice whiter background (I personally think that the veining isn't as pretty as on the tile I purchased - but that's also personal taste).

The next two photos show two different 3x9 Carrara tiles (the first one has beveled edges).

The veining will differ depending on where in the quarry the marble has been sourced.

Your tiles appear to be a lower quality of "Carrara" - I actually question whether it was sourced from Italy. However, if you like it, that's all that matters. However, if you are trying to "match" it, you may need to look at larger sizes from big box stores - and then have the tiles cut down to the size that you need. I think that you'll have a better chance of finding some tiles that will work + you can return whatever tile that you don't use.

You state that you are renovating the bathroom--what exactly are you doing? This will determine whether you need to totally replace your tiles or not. As danni and eld said, matching natural marble is exceedingly difficult.

Thanks everyone for the comments amd follow uo questions. i’m replacing the bathtub with a shower so I wont need to replace all the tile just a small ammount on the floor near the tub and on the wall where the fixtures are and where the tub is.

Thanks everyone for the helpful commenta and questions. i am replacing the bathtub in the bathroom with a shower. So I wont need to replace all the tile, just some on the floor and the wall where the tub’s footprint is

Got it--so what you need to do is bring home some marble tiles and compare them to what you already have. You may be able to get something that kind of matches, but there's no guarantee. The other option is to get something entirely different, something that contrasts with the existing marble, but works with it. Perhaps black marble, or a plain porcelain tile. If you're replacing the tub with a shower, all the floor and walls in the shower will need to be replaced. Maybe you can re-use some of the tiles that you already have elsewhere.

If you show a photo of your existing bathroom you might get more ideas.

This is my daughter’s bathroom. She wants a shower with a door to replace tje tub. Thank you again everyone!
