Bottle Bumper dimensionsUpdated 3 days ago
TL;DR: Bottle Bumpers are moulded to the base of the Atomiser Spray Bottle and Foaming Spray Bottle. They are soft food-grade silicone that stretches over the base for a snug grip, with no adhesive. Fit on other brands of bottle is not guaranteed, since the bumpers are designed around the specific base shape of Koh’s spray bottles.
What size are Bottle Bumpers, and what do they fit?
Bottle Bumpers are not sold to a stated measurement. They are moulded to the base shape of Koh’s two spray bottles, so the size you need is decided by the bottle, not by a number. One size fits both.
✓ Atomiser Spray Bottle
Translucent white trigger, sprays a fine mist from any angle. Designed for Universal Cleaner. The bumper stretches to grip the base.
✓ Foaming Spray Bottle
Green trigger, foams on contact. Designed for Koh’s foaming formulas. The bumper stretches over the base for a snug grip, exactly as it does on the Atomiser.
How does a Bottle Bumper fit the bottle?
✓ A stretch fit, no adhesive
The bumper is soft food-grade silicone moulded to the base shape of the Atomiser and Foaming Spray Bottle. Dry the bottle, stretch the bumper over the base, and work it up until it sits flush. It grips firmly with no adhesive. A little soapy water helps it slide on if it feels tight, and warming it briefly under hot, not boiling, tap water restores the stretch if it feels loose. Full method in how do I use Bottle Bumpers.
Will Bottle Bumpers fit bottles that are not Koh’s?
⚠ Fit on non-Koh bottles is not guaranteed
Bumpers are designed around the specific base shape of the Atomiser and Foaming Spray Bottle. On a third-party bottle with a similar base, a bumper may stretch to fit, but grip and stability are not guaranteed and it may slide or feel loose. For a reliable fit, pair them with Koh’s own spray bottles.
Do the different colours fit differently?
✓ Same shape, different job
Yellow, blue, green and purple are the same shape and the same soft food-grade silicone, so any colour physically fits either bottle. The colour exists to tell you which cleaner is inside: yellow for kitchen, blue for bathroom, green for universal, purple for stain remover. See how do I tell my bottles apart.
All four colours in one pack. Soft food-grade silicone with an anti-static oil finish, sized to Koh’s spray bottles.
One of the two bottles the bumpers are moulded around. Pairs with Universal Cleaner and the green bumper.
