This is Blum's solution for creating proper storage in the awkward space beneath your sink. The banio system converts a standard LEGRABOX drawer into a functional under-sink drawer by using an H-shaped frame that works around your plumbing.
Where It Fits
The system is designed specifically for sink base units where you want to reclaim the space that pipes and waste connections normally make unusable. It works with LEGRABOX M, K, or C height drawers, so it fits into most contemporary kitchen designs where soft-close drawer storage is preferred over traditional cupboard doors.
How It Works
The white H-frame sits inside your drawer and creates a clean opening that accommodates the sink's pipework. You cut the frame to the exact size needed for your particular sink and plumbing layout. The frame conceals the cut edges of the drawer back, giving you a finished appearance even where material has been removed. The drawer still operates normally on its LEGRABOX runners, but now it can slide out fully despite the pipes.
Why It Matters
The space under your sink typically becomes a cluttered void where cleaning products get pushed to the back and forgotten. With this system, you get a proper drawer that pulls out completely, making everything visible and accessible. This is particularly valuable in smaller kitchens where every bit of storage space counts.
Design Consideration
This works well when you want the visual consistency of drawers throughout your base units, rather than having doors only at the sink. However, it does require careful measurement and cutting during installation. The system has specific size limitations, accommodating void widths from 99mm to 435mm, so it won't work with every sink and plumbing configuration.
Build Quality
The frame is made to work with 16mm MFC drawer backs and bases, which is standard for most quality kitchen construction. It comes with Blum's lifetime guarantee, reflecting their confidence in the mechanism. The white finish matches most contemporary kitchen interiors.
Options
The system can be cut in 16mm increments up to a maximum void of 435mm wide. It accommodates various depths from 48mm to 283mm and drawer back heights from 63mm to 148mm when including the cut bracket. This flexibility means it can work with most common sink and plumbing arrangements.
Closing Guidance
Consider this if you're planning LEGRABOX drawers throughout your kitchen and want to maintain that consistency at the sink base. It requires precise measurement and installation, so factor this into your project planning. The investment makes sense if accessible under-sink storage will genuinely improve how you use your kitchen daily.
