How to Secure a Wobbly Toilet with Shims · Step 1 of 5
In this video
Use pliers to tighten the nuts on both bolts. Tighten each side a little at a time to ensure even pressure. The toilet should be snug and not wobble. Be very careful not to over-tighten, as this could crack the porcelain base. Once secured, place the decorative plastic caps over the nuts. Reconnect the water supply line, turn the water on, and flush the toilet a few times to check for any leaks around the base.
Goal: Finalize the toilet installation
- Do not over-tighten the nuts. This is the most common cause of cracked toilet bases.

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.
