Hotel Amenity Bottles: 30 and 50 ml, and Why the Lock Matters More Than the Logo
By Joe Joo · 8PCK · Shantou · Updated 26 October 2026
Hotel amenities are bought by the thousand, refilled by housekeeping, and judged by whether they leak in a trolley. The bottle is commodity; the closure and the lock are the product.
Guest amenities run in 30 and 50 ml, in PET or HDPE, with a flip-top or a disc-top. The specifications are unforgiving: the same bottle is handled by staff, refilled or replaced daily, and stored in a trolley that moves.
This page covers the sizes, the closure that survives housekeeping, and the refill versus single-use decision that most groups are now making.
The free Bottle Spec Checker tests whether your neck fits the closure and whether the wall survives a pump stroke.

The Closure Decides the Complaint Rate
A guest amenity bottle is opened wet, in a shower, by someone who does not care about the pack. A flip-top with a shallow spigot leaks into a washbag; a disc-top with a valve does not.
Hotels also refill: a closure that is re-opened daily wears its thread within weeks. A slightly deeper thread costs nothing at mould stage and doubles the refill life.
Flip-Top
lowest unit cost and familiar; the spigot depth is the specification that matters.
Disc-Top With Valve
No flow until squeezed, which is what a shampoo or lotion needs in a bag.
Screw With Gasket
Most reliable in transit, least convenient in a shower.
Refillable Versus Single Use
A refillable amenity pack needs a thicker wall, a durable thread and a label that survives cleaning. It costs more per unit and less per stay, which is why groups with high occupancy moved first.
For a single-use programme, the pack is chosen for cost and recycled content rather than durability.
30 Or 50 ml
30 ml is the housekeeping standard for a one-night stay; 50 ml suits two-night and resort formats. The bottle is often the same mould family with a different fill.
Questions We Get on This
What size are hotel amenity bottles?
30 ml for a standard one-night set; 50 ml for two-night and resort formats.
Which closure survives housekeeping?
A disc-top with a silicone valve, or a flip-top with a deep spigot. Shallow flip-tops are the usual leak.
Can amenities be refilled?
Yes, with a thicker wall and a deeper thread; that is a different specification from single-use.
What is the MOQ?
1,000 pcs per colour; hotel programmes often order 10,000–50,000 pcs per SKU.
Is rPET available?
Yes, at 30 % or higher depending on grade; colour shift is the usual trade-off.
