Loose Or Rocking Toilet Seat

What's happening?

A toilet seat is held by two bolts down through holes in the back of the pan, and there is almost nothing to grip. On the older pattern the bolt passes right through and is held by a wing nut underneath; on the modern top-fix pattern an expanding plug is pushed into the hole from above and the bolt pulls it tight from the top. Both fail the same way — a nylon nut goes brittle, a washer perishes, or the expanding plug has never gripped in a hole that is slightly too big for it. Because the seat is at the back of the pan and every sit levers it forward, an almost-tight fixing works itself loose within days, however hard it was tightened.

What usually causes it?

• Nylon nuts or washers perished and no longer holding tension
• A top-fix expanding plug that does not grip in a hole slightly too large for it
• The rubber or plastic seat pads worn away, so the seat rocks on the china
• Fixings not designed for the pan's hole spacing or hole size
• The bolts overtightened at some point and the threads stripped or the plastic cracked
• A hinge post cracked at its base, so the seat moves however tight the fixing
• Cleaning products degrading the plastic fixings over time

When should you call a handyman?

Call a handyman when the hinge posts or the seat itself have cracked, when the pan's hole spacing does not match any standard kit, when a soft-close seat has failed, or when you would rather someone else worked under the pan in a tight cloakroom. It takes minutes and it is a common thing to add to a list of small jobs.

What will the handyman actually do?

• Remove the seat and assess whether the fixings, the pads, the hinges or the seat have failed
• Fit a complete replacement fixing kit matched to the pan's hole type and spacing
• Replace worn seat pads so the seat beds evenly on the china
• Fit a new seat where hinges or the lid have cracked, matched to the pan shape
• Tighten to hand-tight without over-stressing the china, and check the seat under load
