Depends a bit on how much heavy duty this sink will be doing. People used semigloss paint behind counters for ages with no problem (wipes down fine), but if you expect lots of splashing and buckets and so forth, then more protection might be merited. I'd let it go until you've lived with it a bit.

The electrical outlet could pose a problem to adding a 4” tall row of tile around the countertop as the electrical cover will extend below the outlet receptacles a bit. If you tile, be sure the tile height does not interfere with the electrical outlet, although it might not be too hard to raise on its own.

If you use your laundry sink like I use mine you will need more than a 3 -4 in backsplash. I use mine for dumping buckets, cleaning paint supplies, all the messy stuff. A solid one piece of laminate or equivalent attached to the wall from the sink to bottom of the cabinets works best.

I can't tell, but it looks like the hole for the faucet might be too far back for a 1.5" countertop material backsplash to fit. Use the tile suggestion made above. If it was me, I'd put hydroban or red guard, like in a shower, and to specs, before I tiled.

It's fine. Just live with it for a while and see how much you "splash" I have no back splash on my laundry room tub, have had for 9 years without any problems.

If you feel you need a backsplash, how about a simple, DIY tile job? Cheap and practical.

Are those quartz countertops? If you want backsplash, even only to be on a safe side, you can simplify things and use the same material for backsplash as you used for countertops. Quartz is water resistant and will look gorgeous.

Aqua............what do you think the thread was about? : ) That's what she asked. "Where's my matching "splash"? lol

I think some pretty tile would look a lot better than a 4" splash piece anyway. Find a pretty tile that coordinates and it will look lovely. I like a subway tile in the lightest colour of the veining from your counter quartz. Or a glass tile is nice too if you can find one that coordinates with your counters and your cupboard colours.

Thanks. I agree that tile would be nicer than the 4" of quartz (and we are doing exactly what you suggested in the kitchen - glass subway in a very pale grey/white). The issue is that this is the laundry room and I don't want to spend extra $$ if not necessary (including possible repairs down the road if we leave it with paint only). My question is whether water from the sink (or laundry pipes) will be a problem - potential leaks, mold, etc. which would have been prevented by a backsplash?

@ enduring you might be right. Here's an updated photo with the faucet installed. I can't tell from this whether there would be room for the thickness of the quartz backsplash. So, if we do NEED to add backsplash, it will likely need to be some cheap subway tile.

OP - as others have said, the risk level depends on how you use that sink. If it's for occasional handwashing, the risk is minimal; washing the dog in the sink raises the ante. Leaking pipes inside the wall would be a problem with or without the backsplash. In any case, I can't imagine that buying a box of inexpensive tile and hiring a handyman to install it if you can't do it yourself would be a big expense.

I would do subway tile there.

Side note, the 4” splash on your bathroom sink looks quite thick... how thick is that?

@CES DAS, Maybe the fabricator made a mistake on the templating and didn't cut the sink right, then there was no room for a splash. I'd check out this line of enquiry, cause they may need to be accountable. I'd want the 4" splash, then I wouldn't have to deal with the tile yet, or ever.

You don't have to necessarily do cheap, white subway tile. You barely have more than a few square feet. Is $50 in tile too much? Get something with a little color. Someone mentioned an aqua glass tile.

do a larger size like a 2x8 or 3x12. you won't need that many tiles.

She'd like to save money, remember??

Also, it's not really an easy DIY because you're going to need a lot of cuts to go around the plumbing box right behind the sink, let alone anything else.

Might not be a bad place for one of those white vinyl (?) sheets, sort of like a seamless shower material -- thin, easy to cut, cheap, easy to install and to remove later if needed. Could go just up to the cabinet level on the sink wall.

Nobody has mentioned, what to me, is the real elephant in the room. Why are the washer hookups behind the sink, instead of being behind the washer space, and below the top of the washer? THAT would drive me crazy!

If you can't find the backsplash in the contract, just pay for it and be done. I would want it. If you know the name of the countertop, you can go anywhere and get someone to put it it in.

acm,,,

So, if we do NEED to add backsplash, it will likely need to be some cheap subway tile.

the tiles I showed her are cheap. I asked if $50 for tile was doable. ( she would spend close to that amount for a brushes and a good mildew resistant paint) And those cheap white subway tiles can be had for as little as .18 each.

As for DIY, it's not difficult. the cuts can be done with a hand cutter, or they can rent a tile saw or even borrow one. My point is, it can be done for under $100. Cheaper if you find left over tiles on Craigslist or something. Cutting around the plumbing isn't a big deal. watch some tutorials, read a 'how to cut tile' post. Geez, as a homeowner it's in your best interest to learn how to DIY the simple things.

but hey, if she wants to get the backsplash piece from the countertop, or vinyl tiles, or even vinyl beadboard, whatever. I don't care, I was just showing her some other options.

walmart has these peel and stick metal tiles.

The shut of valves are located in a good spot. You want to be able to access them in a pinch. You don't want to have to move the washer to access them. The drain pipe from the washer will show too, but this is a functional laundry setup. Maybe if the room were larger it could have gone down the wall a bit with a larger cabinet and counter, to the right of the sink. We don't now that dimension. The w/d may need all that room to the right of the sink, so that valve is in a functional spot imho.

The countertop material would fit under that valve box nicely. Many good ideas about finishing the wall. I think you will want a finish in such a nice room.

I think the sink could have been mounted an inch or 1.5" forward from where it is, and you would have the room for a backsplash out of the counter material. It looks like the handle would hit the backsplash if one where placed in as it is currently.

Honestly, it's much ado about nothing ! She's not worried about the aesthetic aspect. The wall isn't going to get soaked! People do in fact.... even

wash walls! With water !!

oh well JMJ, then just paint the walls with a good satin or semi gloss and be done with it. geez,,,just trying to point out that it doesn't take a million dollars to tile a 12" high backsplash.

Put some silicone caulking in the joints and call it a day.

It's the heat , kids. It's the heat:)
