Definitely agree—caulk’s not gonna fix a sink that’s on the move. I’ve had vanities shift just from someone leaning on them too hard. If the brackets or wall anchors aren’t solid, you’re just asking for trouble down the line. Eco caulks have gotten better, but I still keep a tube of the old-school stuff around for anything that really needs to last. And yeah, those gaps are like black holes for random junk... found a Lego under mine last time.
Yeah, you nailed it—if the sink’s shifting, caulk is just a Band-Aid. I’ve had to redo more than a few jobs where someone thought a fat bead of silicone would hold everything together. It’s always the mounting hardware that tells the real story. I do like some of the new eco caulks for touch-ups, but for anything load-bearing or high-traffic, I’m with you—old-school all the way. And those gaps... I once pulled out a Hot Wheels car and half a crayon from under a client’s vanity. Never fails to surprise me what ends up down there.
