Tools & materials
- Flat screwdriver
- Adjustable wrench or socket
- Replacement seat bolts (optional, stay-tight style)
- Gloves
Step by step
- Step 1
Pop open the plastic caps at the back of the seat hinges to expose the bolt heads.
- Step 2
Center the seat on the bowl.
- Step 3
Hold the nut under the bowl with a wrench while you tighten the bolt from above with a screwdriver.
- Step 4
Tighten firmly but stop when snug. Overtightening can crack the porcelain.
- Step 5
If the bolts keep loosening, replace them with stay-tight or rubber-expansion bolts made for this problem.
