Product Description

Product Overview:

The Bosch HSG958DB1A is a premium 60cm built-in combi steam oven from the Bosch Series 8 Accent Line collection, finished in black glass with a minimalist full-touch fascia. Combining conventional oven cooking with advanced steam functionality, it supports everything from roasting and baking through to sous-vide cooking, dough proving, reheating and healthy steam preparation.

Steam Function Plus enables steam cooking up to 120°C, helping retain moisture, texture and nutrients while accelerating cooking performance compared to conventional steam-only systems. Bosch’s 4D HotAir technology distributes heat evenly across multiple shelf levels, while PerfectBake Plus and PerfectRoast Plus use intelligent sensors to automatically regulate cooking performance and cooking duration.

The TFT Touch Display Pro with Digital Control Ring provides a full-surface interactive interface with guided operation and Home Connect integration for remote monitoring and control via compatible smart devices. EcoClean Direct cavity liners and HydroClean cleaning assistance reduce ongoing maintenance requirements, while SoftOpen and SoftClose door operation reinforces the premium fit and finish of the Accent Line range.
