By the way I'm not talking about the sink or the blue wall, just the area around the sink.

Thanks. I'm looking for a DIY solution. I'm renting and don't want to pour money into this since it's not mine. Having the landlord deal with this is not an option don't ask why. Hoping there's a pro on here who could point me in the right direction.

How about Plastidip? You could probably do the whole counter. I've never used it so have no experience with it.

That website does not exist.

The laminate counter has a hole in it that will only continue to deteriorate. It needs to be replaced. Will your landlord let you replace the counter and deduct the cost from your rent?

The landlord will let me do whatever I want but they won't pay for anything. I spent $1500 remodeling the bathroom and they paid me $200 for it... They won't pay anything for the kitchen, it's a long story we don't need to get into. Looking to spend $300-500 to fix this myself.

I was at HD this morning and was told that water will destroy laminate and that I need tile. I'll research this. It gets really wet in that area behind the sink.

It's a rent controlled building. I'm paying 1300/month for a huge 1 bedroom, I've been here 10 years. Market value 1800/month ( that's how much my new next door neighbors are paying ). The place is huge in an amazing neighborhood ( 4 million dollar houses a block away ) with a great view. Doesn't make sense to move unless I buy a house. The place is great, just that sink area is disgusting. The bathroom was horrific but I took care of that already.

The easiest way to fix that countertop is:

Replace it, that countertop had enough.

Why is there so much water accumulation there? Is anything leaking? What is this countertop made of?

A longer spout on the faucet might help. Not a cure. Look on the faucet to find the manufacturer and then search for a longer spout. Should be quite easy to change the spout.

Or find a vintage high back sink that is designed for wall mount faucets. However, trying to fit a pre-fab laminate counter to the sink would be a challenge and still not a good solution because of the particle board substrate used for the counters.

Given that you've lived there 10 years and don't have plans to move but still don't want to make a big investment. what I would do is get a new laminate counter, a new top mount stainless steel sink with an integrated faucet deck and a new deck mount faucet. (Will need to alter the plumbing but isn't a difficult job given the right tools and minimal DIY skill set.).

The Delta 'Classic' is a decent plain Jane faucet @ around $100. DIY is going to push this approach past $500. More if you have to get a plumber. So consider shopping around for a used sink and used (Delta) faucet. I like Delta because they're reliable, easily repaired and parts are readily available. I put a Delta Classic in my kitchen about 10 years ago (temporarily!) when a not very old American Standard faucet broke (the ceramic disc inside) and would have had to wait for parts. Still have the Delta (predictable) and haven't had to repair it.

Why would laminate get wet, if there are no leaks. Something has to be leaking. The laminate that was in this house when I bought it in 2009 had been installed in 1968, and was in pristine condition, just extremely ugly. I have had laminate countertops many times, and never had one get wet by the sink area. I dont know anyone else that has had that problem either, so there definitely has to be a leak somewhere. If the reason for the water isnt fixed, nothing will hold up in that area.

Well said cat_ky! I completely agree.

I was at HD this morning and was told that water will destroy laminate and that I need tile. I'll research this. It gets really wet in that area behind the sink.

I was assuming when you install a new countertop and remount the sink that you will fix the leak. If the leak isn't fixed, you'll have the same problem with tile.

Guys there is no leak. That sink is smaller than it appears in the photo. When I'm cooking or doing dishes the water splashes.

Someone on a different forum recommended I do this, can someone 2nd this?: Remove all the old rot, then get a can of auto-body filler ( BONDO), and form a new backsplash, and countertop.
Sand it smooth, and Krylon the thing.
Get a permission from the landlord, and go for it.

Otherwise, get a scratch and dent laminate countertop from a BOX store, and replace the countertop.
