Not sure I totally agree with the idea that patching is always just a “band-aid.” Sometimes a quick fix actually does the trick, at least for a good while. I mean, yeah, tracking down the source is ideal, but when you’re staring at water pooling under your sink at 11pm, you’re not exactly in detective mode.
Had a weird one recently—my sink ended up off-center after I tried to fix a small leak. Turns out, the previous owner must’ve just slapped some caulk around the base and called it a day. I get that’s not a permanent solution, but honestly, if it holds for a year or two, is it really that bad? Or am I just setting myself up for more headaches down the line?
And about the condensation thing...I never even thought of that until I saw water on the floor and immediately assumed the worst. How do you even tell the difference right away? Sometimes it feels like you need a PhD just to keep a bathroom running.
Had a similar situation once where a “quick fix” was holding up better than expected, but when I finally pulled the sink to check, the wood underneath was already starting to rot. Sometimes those band-aid solutions can buy you time, but they also hide bigger issues that just get nastier over time. As for condensation vs. a leak—if it’s dripping steadily, that’s a leak. If it’s just damp or you see beads forming on cold pipes, probably condensation. I usually run a paper towel along the pipes to check. Not foolproof, but it helps before tearing everything apart.

That paper towel trick is underrated—works way better than just eyeballing it. If you do find rot under the sink, I’d suggest pulling out any damaged wood and swapping in something like reclaimed cedar or bamboo ply. Both are pretty resistant to moisture and a lot more eco-friendly than treated lumber. Also, if you’re re-centering the sink, maybe look at using low-VOC adhesives and sealants. Makes a difference in air quality, especially in small bathrooms.
That’s a solid approach. I like this bit:

Just a heads up—cedar’s great for moisture, but double-check for splinters if you’re cutting it yourself. I learned that the hard way. Also, low-VOC adhesives are smart, especially if you’ve got kids or pets around. Good call on not just eyeballing for leaks... I’ve missed stuff before and paid for it later.
Funny you mention splinters—last time I tried to cut cedar for a shelf, I ended up picking tiny shards out of my palm for days. Gloves are a must, even if you think you’re just making a quick cut. I’ve never tried bamboo ply under a sink, but I’m curious if it holds up as well as cedar over time. Anyone ever had it warp or swell?
On the adhesives, I used to just grab whatever was on sale, but after my dog started licking the cabinet doors (don’t ask), I switched to low-VOC stuff. The smell is way less intense, too.
One thing I’d add: after you swap out the wood, run a bead of silicone around the edges. It’s not pretty, but it keeps water from sneaking in. I learned that after a slow leak turned my new plywood into a science experiment. Live and learn, right?
