Insert Toilet Shims — Identify Gaps for Shims
Part of project
How to Secure a Wobbly Toilet with Shims · Step 2 of 5
In this video
Firmly slide the tapered plastic shims into the gaps you identified under the toilet base. Insert them from different sides as needed until the toilet feels completely stable and no longer rocks or wobbles. If the toilet rocks side-to-side, place shims on the left and right. If it rocks front-to-back, place shims at the front and back.

FAQs
How do I know if my wobbly toilet needs shims or a more serious repair?
Shims are ideal for minor rocking caused by uneven flooring or a slight gap at the base. If the wobbling is significant, accompanied by leaks, or if the toilet moves freely from the floor, you might have loose flange bolts, a damaged wax ring, or a compromised subfloor, which requires more extensive repair than just shims.
Is this project truly 'beginner' level, and can it realistically be completed in 2 hours?
Yes, securing a wobbly toilet with shims is a beginner-friendly DIY task. Most of the time is spent diagnosing, inserting shims, and applying caulk. With the recommended tools and materials, a novice can typically complete it within the estimated 2 hours, assuming no unexpected issues like a broken flange.
Do I need to buy all the specific tools listed, or are there acceptable alternatives?
While the listed tools like a utility knife and adjustable wrench are highly recommended for efficiency and safety, some generic equivalents can work. For example, a basic screwdriver set can replace the specialized flathead, and any sharp utility knife will trim shims. However, a good caulk gun is essential for a clean, professional finish.
What are the most common mistakes to avoid when shimming a toilet, and how do I prevent them?
A common mistake is overtightening closet bolts, which can crack the toilet base. Another is not checking all sides for gaps, leading to uneven shimming. Prevent this by gently hand-tightening bolts first, then incrementally shimming around the entire base until the toilet is stable, ensuring even contact.
