Composite shims are definitely the way to go. Had a client last year who insisted on plastic shims to save a few bucks, and sure enough, got called back after about 8 months because the toilet started rocking slightly. Moisture and temp swings just warp those plastic ones too easily. Switched them out for composite, problem solved—haven't heard back since. Sometimes it's worth spending a little extra upfront to avoid callbacks later...
Composite shims sound good, but honestly, I've had decent luck with plastic ones—maybe I've just been lucky? I did my bathroom about two years ago, and it's still solid. That said, I did put a bead of silicone around the base after shimming, which probably helped keep moisture out. I'm usually pretty cautious about spending extra on stuff unless it's clearly worth it... but your experience does make me think twice. Next time around I'll probably give composite a shot just to be safe. Callbacks are definitely something I'd rather avoid, especially when it comes to plumbing stuff. Thanks for sharing your experience—good reminder that saving a few bucks isn't always worth the hassle later on.
"Callbacks are definitely something I'd rather avoid, especially when it comes to plumbing stuff."
Yeah, callbacks are the worst... learned that lesson the hard way. Plastic shims can hold up fine if you're careful with sealing, but I've seen them go brittle over time, especially in bathrooms with heavier moisture build-up or temperature swings. Composite might cost a bit more upfront, but honestly, the peace of mind alone makes them worth it—at least for me. Glad your setup's holding strong though; proper silicone sealing is probably saving you there.
Yeah, silicone sealing can definitely buy you some extra time, but I'm curious—have you noticed any difference in how quickly plastic vs composite shims wear down over time? I've seen plastic ones get brittle too, especially if there's direct sunlight or major temp swings involved. Composite usually seems sturdier, but I wonder if the cost difference really balances out in the long run. Either way, sounds like you've done a solid job getting it right this time around... gotta feel good about that.
Yeah, silicone sealing does help, but honestly, composite shims tend to hold up way better in my experience. Plastic ones definitely get brittle over time—especially in bathrooms with big temp swings or near windows with sunlight. I've replaced more cracked plastic shims than I can count, while the composites usually stay solid for years. Sure, composites cost a bit more upfront, but considering fewer callbacks and less hassle down the line, I think they're worth every penny. Glad you got your reno dialed in—nothing beats that feeling when it finally clicks into place.
