An Ubbi vs Dekor Plus diaper pail decision usually comes down to one question parents don’t ask until they’ve already bought one: do you want to save money on bags, or do you want to never touch the bag until it’s full? The two pails solve the same problem — containing diaper smell in a nursery — with almost opposite mechanisms.

Quick Verdict: Ubbi wins on long-term cost since it uses regular trash bags. Dekor Plus wins on not having to touch a diaper bag until it’s completely full, thanks to its continuous liner system.
Direct answer: In an Ubbi vs Dekor Plus diaper pail comparison, Ubbi uses standard 13-gallon trash bags, which can save upwards of $200 over the life of the pail compared to proprietary refills. Dekor Plus uses a continuous liner with a trap-door mechanism, letting you empty only what’s full rather than tossing a partially-used bag — but its refills are pricier and harder to find in stores.

The Real Difference: Bag System
This is the single biggest fork in the road for an Ubbi vs Dekor Plus diaper pail decision, and it shapes almost everything else about daily use.
Ubbi is built around standard 13-gallon trash bags — the same kind you’d use in a kitchen can. There’s no proprietary refill to run out of or reorder. Dekor Plus uses a continuous liner system: a tube of plastic (or a washable cloth liner, sold separately) that you feed diapers into, then snip and tie off at a child-proof cutter near the top whenever you want to empty it — even if it’s only half full.
That continuous-liner design means Dekor Plus lets you empty out just what’s accumulated, rather than committing to a whole bag at once. Ubbi’s tradeoff is that once a bag goes in, you’re using it until it’s full or you choose to swap it early and waste the remaining space.
Odor Control: Trap Door vs Airtight Steel
Dekor Plus uses a plastic trap door — you push the diaper through it, and the door swings back into place to block smell. Reviewers who’ve used it note that as the bag fills up, the diaper has to travel farther and requires more force to push through, and there’s a higher chance your hand brushes the pail’s interior near the end of a bag’s life.
Ubbi relies on an airtight steel body instead of a mechanical door. Steel doesn’t absorb odor the way plastic can over time, but several users report that opening the lid on a fairly full Ubbi releases a noticeable smell all at once, since there’s no trap door acting as a barrier between the diaper compartment and the room.
One real household comparison worth noting: a family using both pails at once ended up designating the Dekor Plus for wet-only diapers in a bedroom (easier, more frequent small swaps) and the Ubbi for soiled diapers in a garage specifically because opening it released a stronger smell than they wanted indoors. That’s a useful data point against treating either pail as uniformly “better” — the right fit can depend on where in the house it’s going and what kind of diapers it’s mainly handling.
The Long-Term Cost Math
Dekor Plus refills run roughly $7 per unit when bought in bulk online, and are harder to find in physical stores than Ubbi’s bags, which limits your options if you run out unexpectedly. Ubbi bags cost around $0.10 each since they’re just standard trash bags, which is where the “saves $200 over the life of the pail” claim commonly cited for Ubbi comes from.
Refill capacity claims are worth a grain of salt, though — different retailer listings for Dekor Plus refills report meaningfully different diaper-holding capacities for what appears to be similar packaging (some list around 1,160 newborn diapers per 2-pack, others list up to 3,600 per 6-pack from third-party refill makers). Actual capacity depends heavily on whether you’re disposing of small newborn diapers or bulkier toddler-size ones, so we’d treat any specific number as a rough guide rather than a guarantee for your situation.

|---|---|
| Uses regular trash bags — no proprietary refills to run out of or reorder | No trap door, so opening a fairly full pail can release odor all at once |

| Steel doesn’t absorb odor over time the way some plastics can |
Dekor Plus: Pros and Cons
| Pros | Cons |
|---|---|
| Continuous liner lets you empty only what’s accumulated, not a whole bag | Refills cost more per use and are harder to find in physical stores |

Ubbi vs Dekor Plus: Side-by-Side
| Factor | Ubbi | Dekor Plus |
|---|---|---|
| Material | Powder-coated steel | ABS plastic |
| Bag system | Standard 13-gallon trash bags | Proprietary continuous liner (disposable or washable cloth) |
| Odor mechanism | Airtight steel body, no trap door | Plastic trap door + rubber seals |
| Opening method | Lift lid, child lock available | Foot pedal, hands-free |
| Approx. cost per bag/refill | ~$0.10 (regular trash bag) | ~$7 (bulk online pricing) |
| Color options | 12 colors | A few colors (varies by retailer) |
Which One Should You Actually Buy
If minimizing ongoing cost matters most, Ubbi’s regular-trash-bag system is the more straightforward long-term choice — you’re not tied to a specific refill brand or price. If you’d rather empty small amounts frequently instead of committing to a full bag each time, or you want a hands-free foot-pedal lid, Dekor Plus’s continuous liner is built specifically for that. If odor containment on opening is your top concern, consider where in the house the pail will live — a hallway or nursery closet may matter more than which pail you pick.
Frequently Asked Questions
Do diaper pails actually contain smell better than a regular trash can?
Generally yes, since both the Ubbi and Dekor Plus are designed with sealing mechanisms a standard trash can lacks — airtight steel for the Ubbi, a trap door and rubber seals for the Dekor Plus. Neither eliminates odor entirely once diapers accumulate.
Can you use regular trash bags in a Dekor Plus?
No — the Dekor Plus is built around its own continuous liner system and does not accept standard trash bags the way the Ubbi does.
Which diaper pail is better for cloth diapers?
Both can work as a dry-pail holding area before laundering, though Ubbi’s simple bag-can design makes it easier to line with a waterproof cloth-diaper liner. The Dekor Plus also offers a washable cloth liner option specifically marketed for this use.
Final Verdict
Neither pail is a clear universal winner in an Ubbi vs Dekor Plus diaper pail decision — they optimize for different things. Ubbi is the simpler, cheaper-over-time option built around bags you already know how to buy. Dekor Plus trades a higher ongoing refill cost for a hands-free foot pedal and the flexibility to empty small amounts on your own schedule. Check current pricing on refills for your area before deciding, since availability affects the long-term cost math more than the sticker price does.
How We Researched This
Researched: This comparison draws on manufacturer specifications, retailer refill listings, and several published hands-on reviews and real-household comparisons of both pails. Refill capacity figures varied across sources, which is noted above rather than resolved with a single number, since actual capacity depends on diaper size and use pattern.
