How to Replace Toilet Seat Bumpers

Quick answer: toilet seat bumpers are the small rubber pads under the seat and lid that cushion them when they close. If yours are worn or missing and the seat rattles, shifts or bangs, check the underside of the seat first. If it has bumper slots, press slot-in replacements into the slots, like the toilet seat and lid bumper set (6 pieces) (4 seat bumpers and 2 round lid bumpers). If there are no slots, or the original slotted bumpers are missing and a stick-on fix is easier, clean and dry the seat and press on self-adhesive bumpers such as the stick-on toilet seat bumpers (4-pack).

Both types are in Toilet Seat & Lid Bumpers, part of the Bathroom Fixes & Accessories range.

Slot-in or stick-on: which toilet seat bumpers do you need?

The seat and lid have bumper slots: toilet seat and lid bumper set (6 pieces). Six white rubber pieces, made up of 4 seat bumpers and 2 round lid bumpers, that press into the slots under the seat and lid. They are for replacing worn or missing bumpers, cushioning the seat and lid, and reducing rattling, and they fit most seats with bumper slots.
There are no slots, or a stick-on fix is easier: stick-on toilet seat bumpers (4-pack). A pack of 4 self-adhesive bumpers, each about 4.5 × 2 cm (1.77 × 0.79 in). They stick under the seat, lift it slightly and help stop it sliding and slamming. They suit a seat that shifts or bangs, or one whose original slotted bumpers are missing.

Step-by-step: replacing slot-in seat and lid bumpers

Lift the seat and lid and look underneath for the slots that hold the bumpers.
Remove the worn bumpers from the slots under the seat and the lid.
Press in the new bumpers. The set has four seat bumpers for the underside of the seat and two round lid bumpers for the underside of the lid.
Check each one sits flush. If a bumper feels loose, reseat it so its shoulder sits flush with the underside of the seat or lid.
Close the seat and lid to check they sit evenly.

Step-by-step: fitting stick-on toilet seat bumpers

Clean and dry the underside of the seat where the bumpers will go. The adhesive needs a clean, dry surface.
Plan the positions. Place the four bumpers where they will cushion the seat and help reduce the gap, spaced so the seat sits evenly.
Peel and press. Peel the backing off each bumper and press it firmly in place.
Lower the seat and check that it sits evenly and no longer slides or bangs.

Tips

Use slot-in bumpers when your seat has slots, and stick-on bumpers when it does not or the slots are damaged.
Bumpers cushion and steady the seat. If the whole seat moves at the hinges, check the hinge fixings as well.
The slot-in set is white, so it blends in on a white seat.

Frequently asked questions

What are toilet seat bumpers?

They are small rubber pads under the toilet seat and lid. They cushion the seat and lid when they close, so they rattle and bang less.

How do I know if my toilet seat has bumper slots?

Lift the seat and lid and look underneath. If the old bumpers pressed into slots, or you can see empty slots, use slot-in bumpers such as the 6-piece seat and lid set, which fits most seats with bumper slots.

Can I use stick-on bumpers if the original bumpers are missing?

Yes. Self-adhesive bumpers are useful when the original slotted bumpers are missing or a stick-on fix is easier. Clean and dry the underside of the seat, peel the backing and press them on.

How many bumpers come in each pack?

The slot-in set has 6 pieces: 4 seat bumpers and 2 round lid bumpers. The stick-on pack has 4 bumpers, each about 4.5 × 2 cm (1.77 × 0.79 in).

Will new bumpers stop a toilet seat from sliding?

The stick-on bumpers lift the seat slightly and help stop it sliding and slamming. Slot-in bumpers cushion the seat and lid and reduce rattling.
