"Ended up using a thin shim underneath the pedestal base, and that did the trick."
Yeah, had a similar issue when I installed mine last summer. Floor looked fine at first glance, but turns out it dipped slightly near the wall. Used composite shims instead of wood—figured they'd hold up better against moisture. Been solid ever since.

Interesting you mention composite shims—I hadn't considered moisture issues initially. When I installed mine, I used wood shims and sealed around the base with silicone. It's held up fine, but now I'm wondering if composite would've been a smarter choice long-term...
Composite shims were a smart move—wish I'd thought of that before my wood ones turned into soggy little sponges. Silicone helps, but moisture always finds a way... Your future self will thank you.
"Silicone helps, but moisture always finds a way..."
Couldn't agree more—moisture is relentless. Composite shims are definitely the safer bet, especially with pedestal sinks where water inevitably splashes around. I'd also suggest double-checking your floor's stability before installing. Pedestal sinks can wobble if the flooring isn't perfectly level, and even slight movement can lead to leaks or cracked porcelain down the line. Better safe than sorry...a little extra prep now saves headaches later.
Composite shims are solid, but honestly, I've had decent luck with just silicone. Installed a pedestal sink in my mom's bathroom about two years ago—floor wasn't perfectly level either. Used a generous bead of silicone around the base, cleaned it up nice, and it's held steady ever since. No wobble, no cracks yet...maybe I just got lucky, but silicone alone can hold up fine if you're careful with the install.
