Honestly, you nailed it—water is sneaky, and a “small” crack can turn into a disaster way faster than most folks expect. I’ve seen people try every patch kit under the sun, and maybe it buys you a few weeks, but it’s never a real fix. Once moisture gets into particle board, it’s game over. I always tell people: if you’re seeing a crack, especially in a high-use area, replacement is the safest bet. It’s a pain up front, but way less painful than dealing with mold or a rotted vanity down the line. Epoxy’s fine for a chipped mug, not for something holding back gallons of water every day.
I get where you’re coming from, but I’ve actually had a patch kit hold up for almost a year on a bathroom sink. Maybe I just got lucky, or maybe it depends on the size and spot of the crack? Still, I wouldn’t trust it long-term, especially if there’s particle board underneath. Once that stuff gets wet, it’s toast. If you can swing the replacement now, probably saves a headache later.

Yeah, that's the kicker. Patch kits are fine for a quick fix or if the crack’s in a low-traffic spot, but once water hits particle board, you’re basically on borrowed time. I tried patching a laundry sink once—lasted maybe six months before I noticed swelling underneath. If it’s just cosmetic damage, maybe worth a shot, but structural? Wouldn’t risk it.
Yeah, totally get where you’re coming from. Once water finds its way in, especially with particle board, it’s a ticking clock. I’ve done the patch thing too—looked decent for a while, but didn’t hold up. If you’re just trying to buy some time, sure, but for anything you actually use every day, replacement’s the safer bet. Sometimes you just gotta bite the bullet and do it right.
Cracked Sink Dilemma: DIY Kit or Professional Fix?
Yeah, I’ve tried the patch kits too—looked fine for a couple months, then the swelling started and it was game over. Particle board just doesn’t forgive water, no matter how much you baby it. I get wanting to save a few bucks, but in my experience, you end up spending more in the long run if you keep patching. That said, if it’s a guest bath nobody uses, maybe you can squeeze a little more life out of it... but for kitchens or main baths, I just swap it out now. Learned that lesson the hard way after a tenant called about “mushrooms” under the sink. Not fun.
