Dustbin Size Chart: 7L vs 9L vs 15L Sensor Dustbin Sizes in cm

Choosing the right sensor dustbin size depends on your room, family size, and daily waste volume. InstaCuppa offers three sizes — 7L, 9L, and 15L — each built for a different use. Pick too small and you empty it twice a day. Pick too large and it wastes floor space. This guide breaks down exactly which size fits which room so you buy the right one the first time.

Dustbin Size Chart: How Big Are the 7L, 9L and 15L Sizes in cm?

A 7 litre dustbin from InstaCuppa is 30 cm tall, 24 cm wide and 13.5 cm deep. The 9L floor bin is 32 cm tall and 22 cm wide. The 15L is the bigger size of the same floor bin. Its size in cm is not printed on the listing, so check the pack.

InstaCuppa makes a 7L cabinet bin, a 9L automatic floor bin, and a 15L automatic floor bin. Each one suits a different space. The sizes below come from the listing images on each product page, read on 22 October 2026. The 7L image calls its depth "length". Prices are the store prices on the same day.

So how big is 7 litres? The 7L bin is about as tall as a 30 cm school ruler. It hangs on a door or wall and sticks out only 13.5 cm. The 9L bin is just 2 cm taller, but it stands on the floor. The 15L holds 6 litres more than the 9L. For what each price gets you, see our sensor dustbin price guide.

Dustbin kitne size ke hote hain? (What sizes do these dustbins come in?)

InstaCuppa sensor dustbin 7, 9 aur 15 litre mein aate hain. 7 litre wala 30 cm uncha hai. 9 litre wala 32 cm uncha hai. In English: our sensor dustbins come in 7, 9 and 15 litres. The 7 litre bin is 30 cm tall, and the 9 litre bin is 32 cm tall.

The table below compares the features of all three sizes.

All three sizes open with a touchless infrared sensor and shut with a soft-close lid. The 9L and 15L are the same floor bin in two sizes. They are rated IPX5 and run on two AA batteries. IPX5 means "Water projected by a nozzle (6.3 mm) against enclosure from any direction shall have no harmful effects", as the IP code definition puts it. So splashes are fine, but do not dip the lid in water. The 7L cabinet bin uses three AA batteries, as its listing image shows. Its listing does not state a water rating.

When Should You Choose the 7L Cabinet Bin?

Pick the 7L when you need a hidden, space-saving bin for bathrooms, bedrooms, or small offices.

The InstaCuppa Smart Sensor Cabinet Bin 7L (Rs 1,599) hangs inside a cabinet door with its hanger, or on a wall with its self-adhesive hook. No drilling is needed. Inside a cabinet door, it stays out of sight. It was sold out on 22 October 2026. Until it is back, the InstaCuppa Hanging Trash Can 9L (Rs 899, in stock) hangs on a cabinet door the same way. That bin has a manual flip and slide lid, not a sensor.

This size works best for rooms with light, dry waste. Bathrooms produce cotton pads, tissue, floss, and small packaging. Bedrooms collect tissues, wrappers, and hair ties. An under-desk setup handles paper scraps and sticky notes. For one or two people, 7 litres of this light waste often lasts a day or two.

The cabinet bin is also ideal for Indian bathrooms where floor space is tight. Many Indian bathrooms are small. A floor bin takes up space and gets splashed during showers. A wall-mounted sensor bin stays off the floor, and at 13.5 cm deep it sits close to the wall.

When Should You Choose the 9L Automatic Dustbin?

Pick the 9L for daily-use rooms like the kitchen, nursery, or office where waste is moderate.

The InstaCuppa Automatic Dustbin 9L (Rs 1,399, list price Rs 1,499) sits on the floor and opens with a hand wave. It stands 32 cm tall and 22 cm wide. It is the most flexible size in the range. It works as a kitchen bin for a couple or small family. In a nursery, it can take the day's used diapers if you empty it daily. It also fits beside a desk in a small office.

For a family of 2-3 people, the 9L handles a full day of mixed waste — vegetable peels, tea bags, packaging, and tissues. You empty it once at the end of the day. It sits next to the kitchen counter without blocking cabinet doors or walkways.

The 9L is also a good size as a gift. At Rs 1,399, it is useful and easy on the budget. It makes a practical housewarming or baby shower gift, since every home needs a bin.

When Should You Choose the 15L Automatic Dustbin?

Pick the 15L for the main kitchen bin in a family of 4 or more, or for high-traffic office common areas.

The InstaCuppa Automatic Dustbin 15L (Rs 1,599) is built for heavy daily use. A family of four to six that cooks at home fills a bin fast with vegetable peels, cooked food scraps and packaging. The 15L bin gives this waste more room, so one empty a day is usually enough.

In offices, the 15L works well in the pantry or common kitchen area where many people share the space. It handles lunch packaging, tea cups, and food waste without overflowing before end of day.

The extra Rs 200 over the 9L (Rs 1,599 vs Rs 1,399 on 22 October 2026) gets you 6 more litres. That is two-thirds more space. If you are between sizes and your kitchen serves a joint family or heavy cooking happens daily, go with 15L. Under-sizing means you empty twice a day or the bin overflows — both are frustrating.

How Do You Decide Based on Family Size?

Use this simple rule: 7L for 1-2 people, 9L for 2-3, and 15L for 4 or more.

A single person or couple makes a small amount of waste each day. The 7L handles this for the bathroom and bedroom. The 9L handles it for the kitchen. A family of 3-4 makes more waste every day. The 9L works if you empty it once a day. A family of 4+ or a joint family with 5-6 members should go straight to 15L for the kitchen and use 7L or 9L bins in other rooms.

Many families use two or three bins across the home. A common setup is one 15L in the kitchen, one 7L in the master bathroom, and one 9L in the nursery or bedroom. This covers all waste points without cluttering any single room.

Does Room Size Affect Which Dustbin to Choose?

Yes — smaller rooms need the compact 7L, while kitchens and large rooms handle the 9L or 15L easily.

Indian apartments often have compact rooms. A studio or 1BHK has limited kitchen space. The 9L bin fits beside the counter without blocking movement. In a 2BHK or 3BHK, the main kitchen usually has enough space for the 15L. Place it near the sink or prep area where most waste is generated.

For very small bathrooms, the wall-mounted 7L is the most practical option. Floor bins in tiny bathrooms get kicked, splashed, and are hard to clean around. The cabinet mount lifts the bin off the floor completely. For a full guide on bathroom dustbin options, see our best dustbin for bathroom article.

Can You Use Multiple Sensor Dustbins at Home?

Yes — most Indian homes benefit from 2-3 bins placed in different rooms for maximum hygiene.

A single bin for the entire home means carrying waste from the bathroom to the kitchen. That is messy, inconvenient, and spreads germs. Instead, set up a bin where waste is actually produced. The most popular home setup is: one 15L in the kitchen for cooking waste, one 7L in the master bathroom for personal care waste, and one 9L in the bedroom or nursery for tissues and light waste.

At 22 October 2026 prices, all three bins cost Rs 1,599 (15L) + Rs 1,599 (7L) + Rs 1,399 (9L) = Rs 4,597. The 7L was sold out on that date. That covers your entire home with touchless, hygienic waste disposal in every room. Each bin runs on its own AA batteries and needs no wiring or plumbing.

What Happens If You Pick the Wrong Size?

A bin that is too small overflows by evening. A bin that is too large wastes space and money.

The most common mistake is buying a 7L bin for the kitchen. It fills up by lunchtime in a family of 3, especially during heavy cooking days. You end up piling waste on top or placing it beside the bin — defeating the purpose. On the other hand, a 15L in a bathroom costs Rs 200 more than the 9L, and the bin sits half-empty on the floor. A wall-mounted 7L would keep that floor clear. Match the size to the room and family, and you will be happy with the purchase for years.
