Sink Franke Sirius SID 110-50 Tectonite onyx — single-bowl built-in sink, Tectonite material

Franke Sirius SID 110-50 Tectonite onyx is a built-in single-bowl kitchen sink designed for standard countertop installation. The compact design in onyx finish is intended for small to medium kitchens where a streamlined sink footprint is required. Made from Tectonite, the surface is uniform and engineered for everyday dishwashing and food preparation tasks while maintaining a contemporary appearance.

Advantages

The Tectonite construction delivers impact resistance and a consistent surface texture that resists chipping and visible seams. The single-bowl layout optimizes usable basin space within a compact external dimension, simplifying installation and cleaning. The onyx finish provides a neutral, scratch-concealing appearance that integrates with a wide range of countertop materials and kitchen styles.

Suitable for

• Compact kitchens and small workspaces where countertop space is limited
• Households needing a durable, low-maintenance single-bowl sink
• Renovations requiring a standard built-in sink cutout
• Everyday dishwashing, produce washing, and basic food preparation

Key specifications

• Configuration: single-bowl built-in sink
• Material: Tectonite composite for a uniform surface and impact resistance
• Finish: onyx (dark, matte-like appearance)
• Installation type: standard countertop inset installation
• Design focus: compact dimensions for small to medium kitchens

How to use

Install the sink into a compatible countertop cutout following manufacturer guidance for inset mounting; ensure proper sealing between sink rim and countertop to prevent leaks. Use the single bowl for washing dishes, rinsing vegetables and fruits, and other typical kitchen tasks. Rinse the basin after use to remove food residues and allow drainage. Avoid exposing the surface to open flames and prolonged contact with extremely hot cookware to preserve the finish.

Usage recommendations

Clean regularly with a soft sponge and mild detergent; avoid abrasive pads or harsh chemicals. For best results, wipe dry after use to reduce watermarks and maintain the onyx appearance. Use sink accessories sized for single-bowl sinks—such as a drainer rack or silicone mat—to protect the surface and organize tasks.
