Before doing that you could see if floor and decor or a local countertop dealer has something that might be a close match to your top. Strange that they don't offer a matching backsplash.

Is this the actual top on the vanity AND your flooring?

Not loving that, sorry.

What are the other elements in the bath aside from the flooring? What is the extent of changes you are making?

Show the entirety of the existing bath?

Thank you!

I wouldn't go through all the trouble and expense of renovating the powder room and leave that floor. Perhaps you could persuade him. The floor tile really doesn't work at all with the vanity and marble top.

Jan and Diana - Thank you for taking the time to share your comments. I am disappointed that you didn't answer my question regarding the potential use of base molding for a backsplash. Instead, I will answer your questions.

As I mentioned, this is a powder bath. The toilet and the flooring (also in our kitchen and laundry room) will remain. The banjo counter, builder-basic mirror, and pickled oak vanity will not. Plumbing issues in the wall will be corrected, and we have additional tile to install in the space where the old vanity was.

The picture of the new vanity orginally posted is the one that was on the showroom floor with clearly a Carrera marble top. I used it to show the color of the wood against my tile floor. I chose the Eternal Marfil counter option. The combination of white washed walnut and Eternal Marfil was the only vanity I could find that would compliment my flooring, given today's world of white or gray vanities with marble tops. See photo below for a better representation. Doing something custom is not in the budget. Walls and baseboard and window sill will be painted some shade of ivory/beige, similar to SW Patience or Divine White. Color will be added in through art, which is TBD.

Now that you know the back story, what suggestions might you have for a backsplash? Would the base molding idea that I originally posted work? Or are there other options that I should consider? I am not looking for a busy tile. The floor has enough pattern for such a small area.

I look forward to your thoughts.

Everyone is so stunned by the flooring combined with that vanity they didn't get to your question.

NO, YOU DO NOT USE WOOD BASE MOLDING AS A BACKSPLASH UNLESS YOU ARE A SHOEMAKER!

Take the time to do this right or don't do the project. Think all the decisions through before you start.

If that floor stays, that is not the right vanity for your room. Consider a walnut-finish vanity to contrast the floor. The vanity selected is designed to be placed away from the wall, not up against it. Is that what you want? If not then select a vanity with a base that can be placed against the wall.

See below. Vanities with legs are held away from the wall.

BTW the use of mosaic tile on the back wall becomes the backsplash for the marble top.

You're rather asking the impossible way ?

Buy a vanity with NO provided top. Have a Corian top made in a soft white......plain, like Corian "Vanilla the original Dupont and under mount the sink of your choice in white vitreous china, American Standard.

Doing that WILL get you the matched backsplash.

Sometimes the urge to retain a surface, save money ( which we all understand ) just hangs up the process, and ultimately costs more than biting a bullet, and getting a better result for long term happiness.

One decision, always begets another: )

You paid 2769.00 for this vanity, and probably for a few hundred more? Could have done custom everything.

A Black vanity, a deep green vanity!! a warm toned grass cloth wallpaper on the walls.... a Simple white ,plain top in a remnant....and add your art. I'd paint the trim white to pick up top, toilet counter. Fresher too: )

WITH WHITE TOP, art.....no worry on nail holes....they disappear,

I believe the OP is talking about ceramic base molding as that is what the examples posted are -

Still will look like a miss.....: ))

It appears that eternal marfil quartz is a Silestone product. I’d look for a silestone dealer and see if you can have one fabricated.

"Everyone is so stunned by the flooring combined with that vanity they didn't get to your question."

"NO, YOU DO NOT USE WOOD BASE MOLDING AS A BACKSPLASH UNLESS YOU ARE A SHOEMAKER!"

BeverlyFLADeziner that base is TILE Base, not wood. So stunned to not read either, lol.

So to address your question, no I wouldn’t use a tile base molding for a backsplash. I agree that the vanity in no way works with the floor. The colors are off and don’t work together. Do as Jan suggested and get a painted vanity . Then get a Corian top and matching backsplash.

Take a happy pill millworkman we all read quickly sometimes even you. IMO it will look exactly what it is base on a wall for backsplash there have to be large format tiles that could work
