Bathroom Sink Splashing Problem

last year

Hello everyone, I'm having difficulty with the bathroom sinks in our new home and need some help. The water in our sinks splashes out of the bowl all over the counter stops, and even all the way up to our mirror on a few occasions. I've tried multiple solutions. The water pressure in the house is down to the safe minimum, I've adjusted the flow valves under the sinks to a minimum, and I've replaced the aerators in the faucets with the lowest flow I can find. Nothing seems to work. Since this is a new home, I'd like to avoid replacing our hardware (if that would even resolve the issue). Any ideas?

The facets are Moen brand if that helps.

"How wide are you opening the taps?" means how much water flow are you allowing?

How wide are you opening the taps? Posting a short video of what's going on might help.

They use a 16.5mm aerator if that helps. Smaller than standard size.

Thanks for the comment. So far the vanity itself, and even the sink, are posing no problem (keep your fingers crossed). More of a compatability issue between the Ikea sink and non-Ikea faucet. Lucky for me, I guess, I don't care that much about the faucet, so I'm just going to return the Kohler and buy an Ikea one. I do think Ikea should let consumers know that this is an issue.

I had the exact same problem. I picked out the vanity I wanted but did not think about the fact that it wasn't made to sit flush against the wall. I spent a month looking for something else, but in the end we decided to go with something shorter and have it not be against the wall. But we were going from 72" to 60" which is probably not workable in your mom's situation. I did find a lot of vanities that did have flat sides and could work in a corner, if you are willing to have the countertop fabricated. They just need to not have any trim detail on the top or bottom like the one you picked out does. I would just look at the ones without the pre-made tops. Because the pre-made top will still leave you with a slight gap because of the countertop overhang. This is an example: Avanity Modero which is sold everywhere, not just at Lowe's. The cabinet we ended up buying is an Avanity Madison which won't work for you, but I assume it is of similar quality. We are pretty happy with it. The drawers and doors have soft close but I do feel like the glides in my Ikea kitchen drawers are better quality. It is very pretty and I wanted a stained wood so I am really happy with our choice. If I had been willing to go with a painted finish, I think we might have stuck with the 72" Modero.

Bathroom back splash, or not?
Q
Comments (12)
I asked the same thing a few days ago because I don't like the look of the backsplash and don't want one and don't feel I'll need one (I never have water on the sink). A couple people told me to do the backsplash, one said I didn't need to.

But, before you even think of what is going to coat the wall behind the sink, make sure that you have a strong substrate behind the plaster to bolt the sink to. If you are putting it back in the exact smae space, are the holes where the old bolts went going to hold the new bolts now that they have been pulled out? Maybe not. You may want to cut out a section of the wall back to the studs and replace it with a 2 x 6 firmly screwed between the studs. Then put on the finish coats. You can screw right into that and be as solid as you need to be.

I believe it’s the angle of your faucet, it faces directly downward. If it had a slight angle it would reduce the splash. We had a similar problem when replacing our kitchen faucet. It is prone to splashing with even a relatively slow flow. Never been a problem with our other faucets.

Thanks JRB, any ideas how to change that?

jrb451-

I've got three 4 bathrooms and 4 different faucets. Three point directly downward; one has a slight angle; none splashes out of the sink.

It looks like a "Cia" model. Their parts list shows two different aerators. Might want to try the one different to yours.

Sinks and faucets should be pulled as far forward as possible to reduce splashing.

KUDZU, they are pretty closed. Only enough water flow to actually be able to use it. If that makes sense...

Wes- Is the splashback entirely a result of water splashing up from the sink when the water stream hits it, or is there possibly an issue with the aerator where some of the stream is spraying outwards from the faucet spout?

ah got your last comment. It's splashing with the tap wide open or partially open.

All of the water is coming from hitting the bottom of the sink and splashing back up out of it. I'll try to get a video of it.

Sink Video Here's a video of one of the sinks being used. Any tips based on this? Note that it spatters regardless of how open the water lines are underneath the sink or how open the taps are at the faucet.

Sinks with a curved bottom always splash…nothing is going to change that…the only solution is to replace it with a flat bottom sink..if cost is crucial…. a sink that size can be found economically anywhere

That's interesting, every sink I had growing up was curved or bowl shaped and never had that problem. Our kitchen sink also splashes up and it's flat...

I have a similar problem with my bathroom sink though if I don't turn the water up too high it does okay. I think it is the shape of our sinks and in your case, combined with the faucet. Does the faucet produce a strong, narrow stream of water? Would this faucet allow a swivel or flexible aerator to be attached to the end? Some cartridge models with the inner plastic parts won't (mine won't) but if it would, it might solve your problem.

Thanks Lisianthus, that is the next thing I was going to try--- a swivel aerator. Unfortunately, our faucet is very narrow and I can only find ones that fit regular sized faucets. I'm thinking we may just have to get new faucets.

That's really disappointing, Wes, and it is such a nice looking faucet.
