How to Secure a Wobbly Toilet with Shims · Step 1 of 5
In this video
The final step is to ensure the toilet is anchored securely. Using an appropriate wrench or socket, tighten the nuts on the closet bolts you located earlier. As you tighten, alternate between the left and right bolts to apply pressure evenly. The goal is to make them snug enough to hold the toilet firmly in place and compress the shims slightly. Be very careful not to overtighten, as applying too much force can easily crack the porcelain of the toilet base.
Goal: Secure the toilet firmly to the floor.
- Do not overtighten the nuts. Porcelain can crack under too much pressure.

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.
