TL;DR - The NEFF Slide & Hide B64CS71G0B is the most distinctive oven in this group: per Neff, the door slides under the oven body, and it costs EUR 1,689 on Neff's Irish site. The Siemens iQ700 studioLine HB776G1B1 is the cheap option at about EUR 860 at one German retailer. The Miele H 7264 BP is the priciest at roughly EUR 2,144 and adds a steam generator.

Three ovens set the reference points here. The NEFF N 90 B64CS71G0B (Slide&Hide, 71 L, EUR 1,689 on Neff Ireland), the Siemens iQ700 HB776G1B1 (pyrolytic, Home Connect, around EUR 860 at a German online shop) and the Miele H 7264 BP (76 L, steam generator, EUR 2,143.85 at one EU retailer). I haven't installed any of them, and I'm not going to pretend otherwise. What follows is what manufacturers and retailers publish, plus where the published numbers changed since this guide was first written.
What "Invisible" Actually Means
So what does invisible mean when an appliance brand uses the term? Three distinct things, which is where the confusion starts.
Flush-mount build: the oven door sits level with surrounding cabinet doors, with no protruding frame or gap. The niche has to be cut accurately; the built-in models here list a 550mm niche depth.
Handleless design: no physical handle bar. The door opens via push-to-open, a j-pull edge, touchless opening on selected Siemens studioLine models, or, in NEFF's case, by sliding under the oven body entirely.
Panel-ready: a custom cabinet panel covers the oven door, making it visually identical to adjacent drawers. It's common for dishwashers and fridges. I couldn't find a mainstream oven at these prices that offers it.
Most products marketed as invisible ovens combine a flush frame with a handleless door, or lean on one of the two. At this price tier, the cabinetry around the oven does most of the disappearing.
NEFF Slide & Hide
The NEFF Slide & Hide has the one genuinely distinctive mechanism in this category. According to Neff, the door slides underneath the oven rather than swinging outward, so it "disappears entirely with a single move."
The B64CS71G0B sits in Neff's top N 90 series. Hughes lists it with a 71-litre cavity, CircoTherm, pyrolytic cleaning, Vario Steam, Air Fry, Wi-Fi and a TFT touch display. Its price has moved: an earlier version of this guide put it at EUR 1,200-1,400, but Neff Ireland lists it at EUR 1,689. The same page shows N 70 Slide&Hide models from EUR 1,309 to EUR 1,489 (for example B54CR31N0B and B54CR71G0B) for a cheaper way into the mechanism. The 13-function count quoted before isn't on any spec page I could open, so it's gone.
Measure before you order. Retailers list a niche of 600 x 600 x 550mm, and the oven measures 595 x 596 x 548mm. That's a standard-size niche. An earlier version claimed the mechanism needs an extra 100mm of depth. I couldn't confirm that, and the figures above point the other way. The installation manual for your model is the final word.
Siemens studioLine
Siemens studioLine is a design line. Siemens' own page describes black glass and blackSteel design elements, and lists touchless door opening on selected models. It doesn't describe a zero-gap frame or say the ovens are handleless, and I found no source for the earlier claim that the carcass must be built to special studioLine dimensions. The HB776G1B1 measures 595 x 594 x 548mm, which is again a standard built-in size.
Prices are very different from what this guide used to say. A German retailer lists the pyrolytic HB776G1B1 at EUR 860 with a five-year warranty (a retailer figure; check who backs it). Siemens' Austrian product page confirms pyrolytic plus hydrolytic cleaning, Home Connect and airFry, and marks steam technology as not applicable. The steam-equipped studioLine compact ovens are a different category: Mykitchens lists two at EUR 2,341 and EUR 2,736.
Worth it? As a standard 60cm oven at a low price, yes. As an invisible one, the honest answer is that the cabinetry does the work. If you want the oven itself to look different, the NEFF is the one that changes the picture.
Miele Generation 7000
Miele's H 7264 BP has a 76-litre cavity, pyrolytic cleaning and an integrated steam generator with a 0.3L tank, according to one EU retailer's spec listing. It has a SoftOpen/SoftClose door and Miele@home connectivity. The niche is listed at 590-595 x 560-568 x 550mm. Its PureLine finish comes with a floating handle, so it is not truly handleless.
The retailer's price is EUR 2,143.85, so it costs about EUR 455 more than the Neff and roughly EUR 1,280 more than the Siemens. Is that premium worth paying? The measurable extras are the larger cavity and the steam generator. Durability is what people usually pay Miele for, and I can't give you a number. Which? surveyed 3,616 built-in ovens in July 2025 and includes Miele, Neff, Siemens and Bosch, but the reliability results are for members only. Older text here said Miele "leads consistently" and runs 15-20 years without fault. I can't source either statement, so both are out. What Which? does publish is warranty length: Neff gives 2 years on parts and labour.
The Cabinet Work Nobody Budgets
Here's the part invisible oven guides skip: the oven is only part of the cost.
Full integration means surrounding unit doors matched in height and depth to the oven front, carcasses cut to the oven's housing dimensions, and handleless mechanisms (push-to-open or j-pull hinges) on adjacent units for visual continuity. In a new kitchen build, a designer factors this in from the start. In an existing kitchen, it's additional carpentry.
An earlier version of this guide put that at EUR 300-800. I couldn't find a published benchmark to support the range, so ask your fitter for a written quote and treat it as a separate line in the budget. A flush oven set into mismatched surrounding units doesn't read as invisible.
Comparing the models
| NEFF Slide & Hide B64CS71G0B | Siemens iQ700 studioLine HB776G1B1 | Miele H 7264 BP Generation 7000 | |
|---|---|---|---|
| Price found | EUR 1,689 (Neff Ireland) | about EUR 860 (one German shop) | EUR 2,143.85 (one EU retailer) |
| Door | Slides under the oven | Not described as handleless | Floating PureLine handle, SoftOpen/SoftClose |
| Steam | Vario Steam (Hughes) | None listed | Integrated steam generator |
| Niche depth | 550mm | Body 548mm | 550mm |
| Cleaning | Pyrolytic | Pyrolytic and hydrolytic | Pyrolytic |
Buy the NEFF Slide & Hide if the sliding door is the point and you can live with EUR 1,689. Choose the Siemens if you want a connected, pyrolytic oven for roughly half that and you'll do the visual work with cabinetry. Go with the Miele if a steam generator and a bigger cavity matter to you. And if even the Siemens price makes you wince, our OZ60 Pro oven review covers a EUR 600-850 pyrolytic built-in that skips the flush-mount theatrics but keeps the cooking substance.
Don't spend EUR 1,700 on a flush oven and fit it into mismatched cabinetry. The integration is the product. The oven is the appliance inside it.
The same logic runs the other way on the worktop. A flush oven buys you a clean wall and then a row of gadgets undoes it, which is the quiet argument for something like the Monsieur Cuisine Smart B1: Lidl lists it as a 23-in-1 machine, in a kitchen where every visible object was a decision.
