The Bambino Plus is the machine I see most often when someone walks up to our counter holding a phone photo of their kitchen. Small machine, nice shots, and a ring of coffee grounds around it by the end of the first week. That's usually when the search for Breville Bambino Plus accessories starts. Good news first. Breville already puts a fair amount in the box, so you don't need a cart full of gear. You need two or three tools that fix the specific thing annoying you, in sizes that actually fit a 54 mm Breville portafilter. This is what you already own, what fits, what I'd buy first, and what I'd leave on the shelf.
The short version
- In the box: a 54 mm tamper, the Razor dosing tool, a 480 ml (16 fl oz) milk jug, single- and dual-wall baskets in 1 and 2 cup sizes, a cleaning tool and a cleaning disc.
- Sizing: tampers and puck screens around 53 to 53.3 mm; dosing cups and funnels made for Breville 54 mm portafilters, not generic 54 mm.
- Buy first: a WDT tool and a spring-loaded tamper. Then a dosing cup and a knock box if mess is the problem.
- Don't replace the milk jug if you use auto-frothing. Breville's manual says the supplied jug has to sit on the temperature sensor.
What comes with the Breville Bambino Plus?
Before you buy anything, open the box again and lay it all out. Breville lists a 54 mm tamper, the Razor precision dosing tool, a 16 fl oz (480 ml) stainless steel milk jug, single-wall and dual-wall filter baskets in 1 cup and 2 cup sizes, a steam wand cleaning tool and a cleaning disc. The US manual also pictures a starter pack of cleaning tablets and descaling powder, though what's in the box can vary by country and retailer.
A word on the Razor, because nobody explains it. It's a trimming tool, not a tamper. You tamp, then twist the Razor across the rim to shave the puck down to Breville's preferred height. Once you start weighing your dose on a scale, you'll find you barely need it. I tell people to keep it in the drawer rather than toss it, because it's handy when you change beans and lose track of the dose.
The baskets matter more than people think. The manual rates the 2 cup basket for 16 to 19 g of coffee and the 1 cup for 8 to 11 g, and Breville builds its recipe around an 18 g dose. If you grind fresh on a real espresso grinder, use the single-wall baskets. The dual-wall ones are pressurized and forgiving, which is great for pre-ground coffee but hides the effect of every puck-prep tool in this article. If you're not sure which you have in the portafilter, our guide to pressurized vs non-pressurized baskets shows how to tell them apart.
What size accessories fit the Bambino Plus?
Sizing is where people get caught out. The Bambino Plus uses a 54 mm portafilter, but 54 mm is the outside of the basket, not the inside. Tools that go into the basket, like tampers and puck screens, are made a touch smaller, usually 53 to 53.3 mm, so they slide in without scraping. Tools that sit on top, like dosing cups and funnels, have to match the shape of Breville's rim, so look for listings that name Breville or Sage 54 mm portafilters rather than a bare "54 mm".
Bottomless portafilters are the trickiest. The locking lugs have to match the group head, and a listing that only names the Barista Express may or may not be checked on the Bambino Plus. If BES500 isn't on the compatibility list, ask the seller before you order. Our espresso tamper size guide has a measuring trick if you want to check your own basket with a ruler.
| Accessory | Size to look for | What to check |
|---|---|---|
| Tamper | 53 to 53.3 mm base | Slides into the 2 cup basket with no scraping at the wall |
| Puck screen | About 53 mm | Room above the puck at your normal dose |
| Dosing cup or funnel | Made for Breville/Sage 54 mm | Seats on the rim without rocking |
| Bottomless portafilter | 54 mm Breville fit | BES500 named on the listing |
| Knock box | Opening that takes a 54 mm portafilter | Footprint beside the machine |
Which Bambino Plus accessories are worth buying first?
A WDT tool and a spring-loaded tamper
If your shots run fast one morning and slow the next with the same beans, puck prep is the usual suspect. Two things go wrong. Grounds come out of the grinder in little clumps, and the stock tamper is easy to tilt a degree or two, so one side of the puck ends up denser than the other. Water finds the easy side and you get sour, thin shots.
A WDT tool, which is just a few thin needles, breaks the clumps up in about ten seconds of stirring. A spring-loaded tamper with a collar rests on the basket rim and presses straight down to the same depth every time, so you stop thinking about angle. On a small counter I like the 53 mm 2-in-1 espresso tamper and WDT tool because the needles store magnetically in the tamper body. One tool, one spot on the counter. Its listing names the Bambino and Barista Express baskets specifically. If you already own a WDT tool, a plain spring-loaded espresso tamper in 53 mm does the tamping half for a dollar less.
Don't buy the tamper for force, by the way. Breville's manual suggests about 30 to 40 lb and then says the pressure matters less than doing it the same way every time. We went through the published tamping tests in how hard to tamp espresso. Short answer: consistency wins.
A dosing cup, if your grinder sprays
Grinding straight into the Bambino Plus basket works, but most home grinders throw grounds past the rim, and then stirring with WDT flicks more out. A 54 mm dosing cup made for Breville portafilters solves both: grind into the cup, weigh it, stir in the cup if you like, then press the portafilter against it and flip. If you're torn between a cup and a magnetic funnel, dosing cup vs funnel walks through which suits which grinder.
A knock box, if the bin is across the kitchen
Banging a hot portafilter on the edge of a kitchen bin cracks bins and dents portafilters. Our 450 ml espresso knock box is small, about 110 by 100 mm on the counter, with a rubber-coated bar and a non-slip base. It holds roughly 8 to 10 pucks, which is a few days of doubles for most households. It's been one of our best sellers this past month, which tells you how many people are knocking pucks into the bin. If you're on the fence, do you need an espresso knock box is honest about when a bin works fine.
A puck screen, only after you check headspace
A 53 mm dual-layer puck screen sits on top of the tamped coffee and keeps the shower screen cleaner. It's a nice-to-have, not a fix. The catch on the Bambino Plus is headspace: at 18 g or more in the 2 cup basket, a 0.8 mm screen can bring the puck close to the shower screen. Try this before you rely on it: prep a normal dose with the screen on top, lock the portafilter in without brewing, then pull it out. If the shower screen screw left a dent in the mesh, you're too full. Our puck screen size and headspace guide covers the fixes.
Bambino Plus accessories compared
If you only have budget for one thing this month, this is the order I'd go in for most people pulling single-wall shots with a separate grinder.
| Accessory | Problem it solves | Priority | Yozcoffee option |
|---|---|---|---|
| WDT + spring tamper in one | Clumps and tilted tamps | Buy first | 2-in-1 tamper & WDT, 53 mm |
| Spring-loaded tamper | Uneven tamps (if you own WDT already) | Buy first | Spring-loaded tamper, 53 mm |
| Dosing cup | Grounds sprayed past the rim | Second | 54 mm dosing cup |
| Knock box | Mess and dented portafilters | Second | Knock box 450 ml |
| Puck screen | Dirty shower screen | Optional | Puck screen 53 mm |
Which accessories can you skip?
A second milk jug is the classic wasted purchase. The Bambino Plus froths automatically by reading temperature through a sensor under the jug, and Breville's manual says the jug must rest on that sensor and that you should only use the supplied jug for frothing. The same manual warns that other containers may lead to dangerous conditions, so this isn't one to experiment with. Keep the one you have. If you steam manually and want a smaller jug for one flat white, that's your call, but it isn't an upgrade.
Also skip extra cleaning discs (you already have one), replacement pressurized baskets, and any bottomless portafilter that doesn't name the BES500. And if you're still on the dual-wall basket with pre-ground coffee, hold off on WDT and puck screens entirely. Spend the money on a grinder first. Owners of the bigger sibling will find a similar list in our Breville Barista Express accessories guide.
What does a good Bambino Plus routine look like?
Here's the routine I'd show a new owner at the counter. It takes about a minute once your hands learn it.
- Weigh 18 g of beans and grind into the dosing cup. Note the grind setting.
- Stir for about ten seconds with the WDT needles, reaching the bottom of the cup.
- Flip into the single-wall 2 cup basket, then tap the portafilter once on the mat to settle the bed.
- Tamp until the spring stops, keeping the collar flat on the rim. No twisting. The most common mistake I see here is leaving a dosing funnel on the basket, which holds the collar off the rim and gives you a shallow, tilted tamp.
- Lock in and brew, aiming for roughly 36 g out. Knock the puck out as soon as you've had the coffee, before it dries on the basket.

What size tamper fits the Breville Bambino Plus?
A 53 to 53.3 mm tamper. The portafilter is 54 mm on the outside, but the basket is slightly narrower inside, so a 54 mm tamper won't go in cleanly.
Does the Bambino Plus come with a tamper?
Yes. Breville includes a 54 mm tamper, plus the Razor dosing tool, a 480 ml milk jug, four filter baskets and cleaning tools. Most owners upgrade it for consistency, not because it doesn't work.
What size puck screen fits the Bambino Plus?
Around 53 mm. Check headspace first: with 18 g or more in the 2 cup basket, a screen can leave too little room. Lock the prepared portafilter in without brewing; if the shower screen leaves a dent in the mesh, drop the dose half a gram.
Can I use a different milk pitcher with the Bambino Plus?
Not for auto-frothing. Breville says the supplied jug must sit on the temperature sensor and should be the only jug used for frothing. Keep the original for auto mode.
Do I need a knock box for the Bambino Plus?
You don't need one, but it stops you banging the portafilter on the bin. A small box with a rubber-coated bar fits beside the machine and holds a few days of pucks.
Do Breville Barista Express accessories fit the Bambino Plus?
Most puck prep tools do, because both use 54 mm portafilters and baskets. Bottomless portafilters are the exception: check that the listing names the BES500 before ordering.
Before you order
Pull three shots this week with what came in the box and write down what bugs you. Shots that change day to day point to a tamper and WDT. Grounds on the counter point to a dosing cup. A cracked bin points to a knock box. Buy for the note you wrote, in 53 mm or Breville 54 mm, and leave the milk jug alone.
