My porcelain kitchen sink somehow got a slight depression in it, causing water to pool in a roughly 7" x 7" area. I'm considering replacing the sink to solve this, but I'm hoping there's instead a cheap, quick hack I can do on the current sink. I don't really care about aesthetics, and I use a sink grid in case that makes a difference. I was thinking I could fill in the depression with some kind of waterproof substance that can adhere to porcelain.
EDIT
Using a level app, I confirmed that the sink is itself perfectly level. The depression rises upwards towards the drain at an angle of about 0.5°, while the non-indented side slopes downwards towards the drain at an angle of 1°.
Here are pictures showing the water pooling. In the second picture you can actually see a dark part of the reflection curving upwards from the bottom, cutting across the lighter reflection to its right. That's the edge of the depression.
Best Answer
Sure, you could fill it with an epoxy, or you could tile it.
Note: Only since you don't care about aesthetics, since I suspect either will look awful in short order, if not right out of the gate. My mind's eye makes a beautiful tile sink bottom (like a shower floor) but the real world experience part of my mind doubts that the detailing at the edges could look good, not to mention mold potential.
Additional Note: First check if you may have a "lifetime warranty" or other applicable warranty on the sink, since some makers do have that sort of policy, but it's out the window if you attempt to fix it yourself, normally.
