NEFF N90 Built-In Single Oven with Steam Function and Slide&Hide Door
An N90 Slide&Hide single oven with FullSteam and VarioSteam cooking, 22 functions and a 71-litre cavity, bringing bakery-style moisture control to a built-in oven.
The B64FS31G0B adds steam to everything the N90 single oven does well. Behind the Slide&Hide retracting door sits a 71-litre cavity with CircoTherm hot air and 22 functions, including FullSteam cooking and VarioSteam moisture assistance fed from a one-litre water tank. It suits cooks who bake bread, steam vegetables and fish, and want crackling roasts that stay juicy inside.
Steam is the difference-maker. VarioSteam adds bursts of moisture during conventional cooking, so bread develops a proper crust, pastry rises evenly and reheated food tastes fresh rather than dried out. FullSteam goes further, cooking delicate dishes gently in steam itself. Both run alongside CircoTherm, letting you combine dry heat and moisture the way professional kitchens do.
Ideal For
Steam in the early stages of baking gives bread an open crumb and a glossy, crackly crust, and keeps pastry and enriched doughs from drying before they rise fully.
FullSteam cooks vegetables and fish gently in moist heat, preserving texture and colour, while the Steam Boost function delivers moisture exactly when a dish needs it.
Combining CircoTherm hot air with added steam keeps joints and birds succulent inside while the exterior browns properly, with the Slide&Hide door making basting effortless.
Key Features
Cook entirely with steam or add moisture at intervals to conventional heat, fed by a one-litre water tank, with Steam Boost on demand.
A broad set of heating and steam functions covers everything from multi-level baking to gentle steam cooking and regeneration.
The fully retracting door slides beneath the cavity with Soft Open & Close, keeping access clear when you are working with hot, delicate bakes.
NEFF's hot-air system cooks evenly across up to four levels at once, so steam baking does not cost you capacity.
Pair the oven with the app over Wi-Fi for remote control and voice assistant support, including preheating before you reach the kitchen.
Rated A+ with 0.69 kWh forced-convection cycles, and EcoClean catalytic liners with hydrolytic cleaning keep maintenance light.
Why steam changes your baking
Professional bakeries inject steam into their ovens because moisture in the first minutes of a bake keeps the surface of the dough supple, letting the loaf expand fully before the crust sets. The B64FS31G0B brings that technique home. VarioSteam releases moisture at the intensity a recipe needs, while the one-litre tank feeds everything discreetly from inside the oven — no plumbing required. The result is bread with real crust, pastry with proper lift and bakes that look like they came from a shop.
Gentle heat for delicate food
FullSteam cooking treats fish, vegetables and grains the way a steamer does: moist, even heat that preserves structure, colour and nutrients rather than boiling them away. Steam Boost adds moisture on demand mid-cook, and steam regeneration revives leftovers so yesterday's dinner reheats without turning leathery. Because the steam functions share the same 71-litre cavity as the conventional modes, there is no separate compartment to manage — one oven simply behaves differently depending on what you are cooking.
The complete N90 experience
Steam aside, this is a proper flagship N90 oven. The Slide&Hide door retracts fully beneath the cavity so you can tend loaves and lift trays without leaning over hot glass. CircoTherm hot air cooks on up to four levels at once without flavours crossing, the Full Touch TFT display keeps its 22 functions organised and quick to reach, and Home Connect adds app and voice control over Wi-Fi. With catalytic EcoClean liners and hydrolytic cleaning, it stays presentable without much effort. For a kitchen that bakes seriously, it is the most versatile single oven in the range.

The Verdict
Strengths
- FullSteam and VarioSteam cooking with Steam Boost
- 22 functions spanning steam and conventional heat
- 71-litre cavity with CircoTherm multi-level cooking
- Slide&Hide fully retracting door
- Home Connect app and voice control
- One-litre water tank, no plumbing required
- A+ energy rating with 0.69 kWh convection cycles
Considerations
- The one-litre water tank needs refilling during longer steam sessions, and emptying and drying after use.
- Cleaning is catalytic and hydrolytic rather than a full pyrolytic self-clean cycle, so some hand-cleaning remains.
- It is a hardwired 3.6 kW appliance requiring installation by a qualified electrician, not a plug-in replacement.
