Every countertop oven strikes the same deal with you: hand over a chunk of counter, permanently, and you’ll get crispy fries whenever you want them. The Ninja Flip tries to renegotiate. You cook, then you fold the whole oven up against the backsplash, and Ninja rates the result at 50% less space.
Ninja’s pitch is “extra-large capacity without sacrificing counter space,” and that’s the kind of promise that lives or dies on a tape measure. So the dimensions are the most important numbers on the page. They’re also where things get strange.
Ninja’s SP151 product page lists exactly one set of dimensions and never says whether they describe the oven cooking or the oven folded. On the same page, it promises the Flip bakes a 12-inch pizza. The width it lists is 10.2 inches. A 12-inch pizza doesn’t fit in a 10.2-inch box (that’s not an opinion, that’s geometry), so at least one of those figures isn’t the cooking footprint. The page doesn’t say which.
TL;DR — Should the Flip Get Your Counter?
- What it is: an 1,800-watt, eight-function toaster oven and air fryer that folds up against your backsplash when dinner’s done. Ninja’s own store lists it at $249.99 (checked September 18, 2026), and Amazon’s price may differ from that.
- It isn’t new, and that’s good news: 4.4 stars across 2,026 Amazon ratings and #3 in Toaster Ovens (Amazon, September 18, 2026). You’re not the test group.
- The eight functions, exactly: air fry, roast, broil, bake, pizza, toast, bagel, dehydrate. No reheat, no keep-warm, no proof mode, whatever the Amazon listing’s one-line blurb says.
- The catch: Ninja’s one dimension row can’t all be the cooking footprint, its product page gives no interior volume or flip clearance, and the spec table’s only word on cleanup is a product-level “Dishwasher Safe: No,” nothing per accessory.
Counter space is the whole pitch here. This is the listing to price-check against Ninja’s $249.99

The Oven That Folds Up and Gets Out of the Way
The trick is as simple as it sounds, and Ninja can’t quite decide how to phrase it. The product description says you can “flip it up against your backsplash when not in use so you can save 50% more space on your countertop.” The feature bullet says the oven “takes up 50% less space.” One number, two phrasings, both Ninja’s.
Here’s what the pitch skips: the Flip folds up where it cooks, so it never really gets put away. It just stands up. That means it lives wherever the outlet is, and the cord is 32 inches, feeding 1,800 watts at 120 volts and 15 amps. If the only free outlet is across the counter from the space you cleared, this isn’t the oven for that corner. At 19.84 lbs, you wouldn’t want to haul it to a cabinet nightly anyway; sparing you that trip is the fold’s whole job. For what that draw adds to a power bill, our guide to what kitchen appliances cost to run does the arithmetic.
The heating hardware is what Ninja calls OvenCrisp Technology: “Infrared heating & circulating air combine for even cooking.” Here’s the odd part. Three of the punchiest numbers for this oven appear in the Amazon listing’s bullets but not on Ninja’s own SP151 product page: “6 infrared heating elements enable a temperature range of 85-450F,” “80% more energy efficient than a traditional full-size oven,” and “50% faster cooking and crisping vs a traditional oven.” They sit on a retailer page, and Ninja’s own page doesn’t repeat them.
Eight Functions, and the One the Amazon Listing Adds
Ninja publishes the list outright, worded the same on its own page and in the Amazon bullet: “Air fry, Roast, Broil, Bake, Pizza, Toast, Bagel, Dehydrate.” Three of them earn a sentence:
- Air fry: Ninja claims “up to 75% less fat than traditional frying methods,” and the Amazon version shows its work: “Tested against hand-cut, deep-fried French fries.” That’s Ninja’s comparison against a deep fryer, not against the oven you already own.
- Pizza: the function that sells the oven, rated for a 12-incher.
- Dehydrate: the eighth name on the list, and a name is all you get. Ninja’s product page gives no preheat time and no per-function cook times, for this setting or any other. The only clock on Ninja’s page is a marketing line: “Family-sized meals that feed up to 4 people in just 20 minutes.”
There’s no reheat, no keep-warm and no proof setting in Ninja’s eight. The listing’s one-line Item Highlight, also tacked onto the listing title, reads “Air fry, bake, broil, toast, bagel, dehydrate, reheat, 1800W, Flip up & away, XL capacity.” It adds “reheat” and leaves out roast and pizza. Ninja’s page and the “About this item” bullet on Amazon’s own listing agree perfectly. The blurb is the outlier, and it’s the line a hurried shopper reads first. If you’re buying the Flip for a reheat button, Ninja’s own function list doesn’t have one.
Capacity comes in food rather than volume: up to 4 lbs of ingredients, that 12-inch pizza, and, in the Amazon bullet, 6 slices of bread or 6 chicken breasts. Ninja prints no quarts, no cubic feet and no interior cavity dimensions on its product page. So whether your favorite quarter-sheet pan fits is a question that page leaves to you. Still deciding between formats? Our air fryer vs. toaster oven vs. microwave breakdown is the better place to start.
The Dimension Row That Could Cost You a Cabinet
Ninja’s full line reads “19.13 in L x 10.2 in W x 18.43 in H.” No label says flat or folded, and you’ve already seen why the 10.2 and the 12-inch pizza can’t both describe the oven in cooking position. The fix is boring, and it works: take all three numbers to the tape measure, not just the one you assume is the footprint.
Amazon’s version is worse, and a calculator shows why. Its catalogue lists the same oven at 17.01″D x 15.75″W x 7.68″H, a 10.75-inch disagreement about height between the company that built it and the store that sells it. Then it prints “Capacity 17.01 cubic inches.” Multiply Amazon’s own three dimensions and you get roughly 2,058 cubic inches of exterior. The 17.01 cubic inches is under 1% of that box, and a cavity that size couldn’t hold the 12-inch pizza the same listing promises. The same 17.01 shows up in both fields, which looks like a data-entry slip, though Amazon doesn’t say so. Plan your gap off Ninja’s figures and treat Amazon’s table as unverified.
What Ninja’s product page doesn’t quantify is the room the flip itself needs. One Amazon reviewer put the risk in a single line: it’s “a great space saver if you have the cabinet height to flip it.” Ninja’s owner’s guide might carry the number. Its support article for the guide says plainly, “This supports the SP151,” but the PDF opens through a script link with no direct file address, so its contents aren’t quoted here. If there are upper cabinets over the spot you’ve picked, look up before you fold up.
The $249.99 Oven and Its $69.96 Parts Bin
The $249.99 is only the first number. Ninja sells every accessory in the box as a separate part, priced right on the SP151 product page: the wire rack at $18.99, the sheet pan and the air fry basket at $19.99 each, and the crumb tray at $10.99. Replace all four and you’ve spent $69.96, about 28% of the oven itself.
Cleanup gets one flat answer in Ninja’s spec table: “Dishwasher Safe: No.” That’s a product-level line, sitting in the same table as the weight and the cord length, and the page gives nothing per accessory. One Amazon reviewer says “Only the basket is dishwasher safe, trays have to be washed by hand,” which is one customer’s report, not a spec. The care section of the owner’s guide is the place to settle it before the box arrives.
There’s one more Flip-specific part on Ninja’s page, and it isn’t in the box: the Ninja Flip Broil Rack, model 636SH151, $18.99. That’s the whole entry. A name, a model number and a price, with nothing on what it does, where it sits or whether the broil setting needs it. If broiling is high on your list, ask Ninja support before you check out.
Who Should Buy the Flip, and Who Should Buy a Flat Oven
Buy it if your counter is the bottleneck
This is the entire case for the product, and it’s a strong one when it applies: a full eight-function oven that stands up out of the way when you’re done. The track record backs it up, with 4.4 stars across 2,026 ratings and “8K+ bought in past month” (Amazon, September 18, 2026). Ninja’s own store shows “5 out of 5 Customer Rating,” which is lovely, and also Ninja’s own store. The 2,026 is the number to trust.
Skip it if you need a number Ninja’s page doesn’t print
Skip it if you plan your pans around interior volume, because Ninja’s product page doesn’t give one. Skip it if noise matters: there’s no decibel figure on Ninja’s product page. And skip it if you need to know how many rack positions there are before you pay, since that isn’t on the product page either.
One field to treat with care while you shop: the Amazon listing’s “Special Feature” tag includes “Automatic Shut-Off.” Ninja’s own product page doesn’t mention auto shut-off one way or the other, so check the owner’s guide before you count on it.
What to look at instead
If the fold isn’t the point for you, compare the Flip against a regular air fryer toaster oven first: our Cuisinart TOA-70 review is the one we’d open, and the air fryer toaster oven combo roundup covers the wider field. If air frying is the real draw and the oven is optional, a standalone air fryer is the other road; start with our Ninja Foodi DZ302 review. And if $249.99 is more than you meant to spend, our list of the best toaster ovens under $100 is the reality check.

Does the Flip Fit Your Kitchen? The Quick Check
Here’s the Flip against the situations that actually decide it:
| If your kitchen… | What the published numbers say | Flip? |
|---|---|---|
| is short on counter space | Folds up against the backsplash; Ninja claims 50% less space | Yes ✅ |
| cooks for four on weeknights | Up to 4 lbs of ingredients or a 12-inch pizza; “family-sized meals that feed up to 4” | Yes ✅ |
| has its only free outlet across the counter | A 32-inch cord | No ❌ |
| runs on a reheat button | Eight functions, none of them reheat or keep-warm | No ❌ |
| puts everything in the dishwasher | “Dishwasher Safe: No” in Ninja’s spec table, nothing per accessory | Check the owner’s guide first ⚠️ |
| Worth $249.99? | 4.4 stars on 2,026 Amazon ratings; one-year limited warranty | Yes, if the fold solves a real problem ✅ |
The Verdict: One Great Trick, One Number You Can’t Read
The Flip is an easy recommendation for one kind of kitchen and a shrug for every other. If the counter’s the problem, this oven is built around exactly that complaint, and at $249.99, with a one-year limited warranty and 2,026 ratings behind it, you aren’t gambling on a first run.
What holds it back isn’t a flaw in the oven. It’s four lines missing from Ninja’s product page: interior volume, noise, the clearance the flip needs, and which state that one dimension row describes. You’re buying a footprint claim you can’t fully check against the maker’s own product page, which is an odd spot for a product whose whole pitch is footprint.
So do the things that protect you. Measure against Ninja’s numbers, not Amazon’s. Look up at the cabinets before you look at the price. Then check the live Amazon price against Ninja’s $249.99, fold it up, and take your counter back.
Ninja Flip SP151 FAQ
How many watts is the Ninja Flip SP151?
1,800 watts, at 120 volts and 15 amps, per Ninja’s spec table. Ninja lists its peak wattage as the same 1,800.
Does the Ninja Flip have a reheat setting?
No. Ninja’s eight functions are air fry, roast, broil, bake, pizza, toast, bagel and dehydrate. The Amazon listing’s one-line Item Highlight says “reheat” anyway; Ninja’s own list doesn’t.
How big is the Ninja Flip inside?
Ninja’s product page gives no interior volume or cavity dimensions, only food: up to 4 lbs of ingredients or a 12-inch pizza. Ignore Amazon’s “17.01 cubic inches” field.
Are the Ninja Flip trays dishwasher safe?
Ninja’s spec table says “Dishwasher Safe: No” for the product as a whole and gives nothing per accessory. One Amazon reviewer reports the basket is dishwasher safe and the trays aren’t; check the care section of the owner’s guide. Replacements run from $10.99 for the crumb tray to $19.99 for the sheet pan or air fry basket.
How much space does the Ninja Flip need?
Ninja lists 19.13 x 10.2 x 18.43 in without saying whether that’s the oven flat or folded, and Amazon lists a conflicting 17.01 x 15.75 x 7.68 in. Measure against Ninja’s figures. Ninja’s product page gives no flip-clearance number, so check the height under any upper cabinets too.
Specs, prices and quotes: SharkNinja’s SP151 product page (store price checked September 18, 2026), Ninja’s SP150 Series owner’s guide article, and Amazon’s B0D1CXL52G listing and reviews (ratings, rank and “bought” figures as captured September 18, 2026). Correction: an earlier version said Ninja hadn’t published a full SP151 spec sheet. It has, and this version is built on it.
