Frequently Asked Questions

Q: Can these leveling shims be used under a toilet to stop rocking?

A: Yes! These plastic leveling shims are specifically designed for use under toilets to eliminate wobble and create a stable, level base. Simply slide one or more shims under the toilet base, trim to fit if needed, and press into place — no tools or adhesives required.

Q: How many shims can I stack together for a larger height adjustment?

A: The shims are fully stackable, so you can layer as many as needed to reach your desired height. Each shim measures 6.5 mm in height, so stacking multiple pieces gives you flexible, incremental adjustments for furniture, cabinets, or appliances on uneven surfaces.

Q: Can I cut the shims to fit in tight or awkward spaces?

A: Absolutely. The soft plastic material makes these shims easy to trim with scissors or a utility knife, allowing you to customize the shape and size to suit narrow gaps, odd angles, or compact areas under furniture and fixtures.
