- Used wooden supports plenty of times, moisture's usually not a huge issue if you seal or paint properly.
- Warping can happen though, especially if ventilation under the sink isn't great...seen it once or twice.
- Good airflow and sealing usually keeps things solid long-term.
"Warping can happen though, especially if ventilation under the sink isn't great...seen it once or twice."
Yeah, learned that lesson the hard way myself. Thought I'd sealed everything perfectly, but after about a year, noticed a slight warp starting. Turned out my ventilation was pretty much nonexistent—rookie mistake, I know. Ended up adding a couple of discreet vent holes at the back and haven't had issues since. Definitely agree that good airflow makes all the difference long-term. Live and learn, right?
Interesting points here, but honestly, I've seen plenty of kitchens with minimal ventilation under the sink that never had warping issues. I think a lot depends on the materials you're using and how they're treated beforehand. A few years back, I worked on a kitchen remodel where the homeowner insisted on a solid wood cabinet base beneath the sink—beautiful oak, sealed meticulously. Ventilation was pretty much zero because they didn't want any visible holes or gaps. Fast forward three years later...still no warping or moisture damage at all.

I mean, airflow certainly helps, but I'd argue that proper sealing and choosing moisture-resistant materials can sometimes be just as important (or even more so). Maybe it's a combination of factors—material quality, sealing technique, and humidity levels in your home—that determines whether you'll see warping or not. Either way, it's always good to hear different experiences...keeps things interesting.
Yeah, I think you're onto something there. I've had a similar experience myself. When we redid our kitchen about five years ago, I was pretty worried about moisture issues under the sink because I'd heard all these horror stories about warping and mold. We ended up going with plywood cabinets, but I spent a ton of time sealing everything up tight—probably went a bit overboard, honestly. Ventilation wasn't really a priority for us either, mostly because I didn't want to compromise the look with extra holes or vents.
Fast forward to now, and we've had zero issues. No warping, no mold, nothing. And trust me, our sink area sees plenty of action—kids splashing water everywhere, occasional leaks from the plumbing (fixed quickly, thankfully), and all the usual kitchen chaos. So yeah, airflow is helpful, but I think you're right that material choice and sealing are just as critical. Maybe even more so in some cases.
I guess it really comes down to how thorough you are with prep and sealing, plus the quality of materials you pick. If you're careful about those things, you can probably get away with minimal ventilation without running into trouble. But hey, every kitchen is different, right? It's always interesting to hear how other people's setups hold up over time.
"I guess it really comes down to how thorough you are with prep and sealing, plus the quality of materials you pick."
Totally agree with this. I've seen kitchens with almost no ventilation hold up great because the homeowner was meticulous about sealing edges and joints. One thing I'd add—don't underestimate the power of a good waterproof liner under the sink. Saved my bacon more than once when a pipe decided to spring a leak overnight...
