Our verdict, if you don’t read another word: the Ubbi steel diaper pail is a 5 out of 5, and it is the one we would buy if we were only ever buying one. This Ubbi diaper pail review comes down to two facts. The body is powder-coated steel, so it does not soak up smell the way plastic does, and it takes the ordinary 13 gallon kitchen bags already under your sink. What it asks in return is a free hand to work the lid.

We own three pails, and this page is the Ubbi on its own. All three sit side by side in our best diaper pail roundup, and the Ubbi against its usual rival is in Ubbi vs Diaper Genie. We review it as gear, the way we review everything here. A diaper pail is a convenience, not a necessity, and nothing on this page is health advice.

What the Ubbi is, and what comes in the box

5 / 5our rating

The list is short. A powder-coated steel body, steel on the inside as well as the outside, so it is not a plastic tub with a metal skin. A sliding hatch on top with a rubber gasket under it. Room for a standard 13 gallon kitchen bag. It comes in a handful of colors, and ours is the blue one.

What is missing from that list matters just as much. There is no refill cartridge, no carbon filter to swap, no bag format you can only buy from one company. Most pails are sold as a system, a container plus a consumable you keep buying. With the Ubbi you buy the container and that is it, which is why we think of it as a diaper pail with the subscription taken out.

Living with the sliding lid

Using it is three movements. Slide the hatch open, drop the diaper through, slide it shut. There is no pedal, no clamshell and no twist, so there is very little in the mechanism that can wear out or jam, and the part that does move is easy to reach and wipe.

What that simplicity costs you is a hand. The hatch needs one, and the moment you are using a pail is usually the moment you have a baby on your other arm, and a foot pedal really is easier. Of the three pails we own, the Ubbi is the one that asks the most of you at drop-in.

There is also a small puff when the hatch opens. It is brief, gone in a second or two, and it comes from an opening that sits flush with the top, with no inner door behind it. Also, the slide gets a little sticky if the rim is dirty. A quick wipe of the track fixes it every time, and the stickiness is a useful reminder that the track wants cleaning.

What we like

  • Powder-coated steel inside and out, so the body does not take on odor
  • Runs on any 13 gallon kitchen bag, with no cartridges or filters to rebuy
  • A plain sliding hatch with very little to break
  • Small enough to live in the nursery itself
  • Looks like a small steel bin, not baby equipment

What we don't

  • The hatch needs a free hand, and you often do not have one
  • A short puff of smell escapes at the moment a diaper goes in
  • The slide turns sticky when the rim gets dirty, until you wipe it
  • Lifting the lid to change the bag can let out a strong smell
  • Costs more up front than a plastic pail

How many diapers it holds, in practice

Ours takes about 45 to 50 diapers before the bag comes out. With a daily count that goes up and down, that is roughly five or six days, and standing in the corner of the nursery it comes up to about knee height.

That is smaller than a cartridge pail like the Genie, which is rated for far more per refill. We have stopped thinking of that as a drawback. What decides when a pail should be emptied is how much smell you are willing to keep in a room with a sleeping baby, and a bag that goes out every five or six days never sits long enough to become a problem. A bigger pail makes it easy to leave the bag in for longer than you should.

Emptying is as plain as the rest of it. Lift the lid, tie the kitchen bag, and it leaves the house with the rest of the trash. You don’t have to reload a cartridge or buy anything proprietary first.

Why the steel matters more than any feature

Most diaper pail marketing is about seals and filters. Where the Ubbi pulls ahead is the material, and you only notice that over months.

Ordinary plastic is slightly porous, and every scuff from a year of opening and closing gives smell somewhere to settle. After long enough, the odor is in the plastic itself, and cleaning knocks it back without getting rid of it. Powder-coated steel is sealed, so when you wipe it down, it comes clean.

For something that will hold dirty diapers for two or three years, and often longer if a second child comes along, that is the property that decides whether the pail becomes a smell of its own. It is also why we rate this a 5 and the plastic Genie a 4.5. With plastic, how the pail smells in year two is a guess. With steel, we are fairly sure.

The bag question is really the cost question

We never list prices on this site, but we can tell you how the money is structured, and with pails that structure is most of the decision.

A cartridge pail is cheap to buy and expensive to keep, because the proprietary refills keep coming for as long as you are in diapers. The Ubbi turns that around. You pay more once, and after that it runs on standard 13 gallon kitchen bags, the same ones the rest of the house uses. You can buy them wherever they are cheapest and switch brands whenever you like.

Across one child that is a couple of years of not buying refills. Across two it is several, and the pail is still the same pail.

Keeping it clean

The places grime collects are the sliding track and the rubber seal under the lid, and five minutes with a damp cloth on those two keeps the hatch moving freely. The steel inside wipes back to clean with ordinary soapy water.

Two things to avoid. Skip scouring pads and harsh abrasives, because the powder coat is what keeps the steel sealed and a scratch in it undoes the point of owning a steel pail. And let it dry fully before a new bag goes in, since trapped damp is what makes any pail smell musty. Our full routine, for this pail and for plastic ones, is in how to clean a diaper pail.

Where it lives in our house

Size decided this more than anything else. The Ubbi is the smallest of our three pails, so it is the one standing in the nursery, in the corner near the changing area. The Diaper Genie started beside the cot and moved to just outside the room because it took more floor than we wanted there, and the Dekor lives in the washroom.

If you only have room for one pail and it has to be in the nursery, that footprint is a real argument. A bigger pail you have to put outside the room is one you will walk to less often, and the diapers end up sitting in the room somewhere else. It also helps that the Ubbi looks like a small steel bin rather than a piece of baby equipment, and in a room you walk into every day, that counts for something.

After the diapers

Most pails are finished the day potty training is. A cartridge pail without its cartridges is an awkward plastic tube, and it usually goes out with the trash.

The Ubbi keeps going. Take the diaper years out of it and you have a clean steel bin with a lid, which will serve in a bathroom, a laundry room or a garage for a long time, and it holds its value well enough to pass on. At the very end of its life it is steel, which recycles.

Who should buy it, and who should not

Buy it if you want to buy one pail and be done, if you expect a second child, or if the idea of a refill subscription annoys you on principle. It also suits a small nursery, since it is the pail that fits in the room, and anyone trying to cut down on single-use plastic, since it adds no product stream of its own.

Buy something else in three cases. If you want to use a pail with both hands full, the Diaper Dekor EKO Classic has the pedal and is the value pick in our house. If the moment of drop-in is what you care about most, say the pail sits right beside where you sleep, the Diaper Genie Complete seals better at that exact second, as long as you budget for its refills. And if money is tight, a lidded can emptied daily does the same job for nothing, which we argue in baby items you don’t need.

The bottom line

A 5 out of 5, though it takes a while to see why. On the first day it is not impressive: a lid you slide by hand and a puff of smell when you do. The case for it builds over months, as the steel stays neutral, the bags cost what bags cost, and the pail looks set to outlast the diapers.

That rating is our judgment, not a score from a table. If a foot pedal matters more to you than what the pail smells like in year two, weigh it that way and the Dekor comes out ahead, which is why both are 5s in our best diaper pail roundup. Ubbi also makes a plastic caddy for the changing table, which we use daily and cover in our Ubbi diaper caddy review.

Frequently asked questions

Is the Ubbi diaper pail worth it?

We rate it 5 out of 5, and it is the pail we would pick if we were only ever going to buy one. It costs more on the day than a plastic pail, then asks for nothing else, because it takes ordinary 13 gallon kitchen bags. The steel body is the other half of the case: it does not soak up smell the way plastic does, so the pail itself stays neutral for as long as you are in diapers.

What bags does the Ubbi diaper pail use?

Any standard 13 gallon kitchen trash bag. There is no refill cartridge and no filter to replace, so the running cost is whatever you already pay for kitchen bags, and you can switch brands whenever you like. That is the main reason people choose it over a cartridge pail.

Does the Ubbi diaper pail smell?

Less than a plastic pail, with one caveat. The sliding hatch lets a small puff out at the moment a diaper goes in, and it clears within a second or two. Between changes the lid and its rubber seal keep the smell inside, and because the body is powder-coated steel, the pail does not slowly take on an odor of its own the way a plastic one can. The caveat is emptying it: lift the whole lid to change the bag and the smell can be strong, more so the longer the diapers have been in there, so emptying it often makes the biggest difference.

How often do you empty an Ubbi diaper pail?

Ours holds about 45 to 50 diapers before we take the bag out, which works out to roughly five or six days, since the daily count moves around. It is a smaller pail than the Diaper Genie, so you empty it more often, which is no bad thing: a bag that leaves every week is a bag that never sits long enough to turn.

Is the Ubbi diaper pail hands-free?

No. The lid is a hatch you slide open by hand, drop the diaper through, and slide shut. It is simple and there is very little to break, but it does need a free hand, which is its one real weakness. If a foot pedal matters more to you than a steel body, the Diaper Dekor EKO Classic is the pedal pail we own and rate.
