## Long description

QUADRON JOHNNY 90 Steingran is a single-bowl granite composite kitchen sink in black with integrated overflow and a dedicated drainer area. The bowl measures 39 x 50 x 20 cm, making it suitable for compact and standard kitchen layouts. The sink is designed for undermount or inset installation in countertops and is supplied with a stainless steel siphon to simplify connection to existing plumbing. The granite composite surface provides a matte finish that resists everyday wear and complements modern kitchen finishes.
Advantages
The granite composite construction ensures good resistance to scratches, heat and everyday impacts while maintaining a consistent appearance over time. Integrated overflow reduces the risk of accidental overfilling, and the included drainer area offers convenient space for drying dishes or preparing food. Compatibility with both undermount and inset installation provides flexibility for different countertop materials and installation preferences. The supplied stainless steel siphon allows for immediate installation without the need to purchase additional drainage components.
Suitable for
 Small and medium-sized kitchens where space efficiency is needed
 Everyday dishwashing and food preparation
 Renovation projects requiring undermount or inset sinks
 Kitchens with modern or dark-coloured worktops
Key specifications

How to use
Install the QUADRON JOHNNY 90 Steingran sink according to the countertop and cabinet layout, choosing either undermount or inset mounting. Connect the supplied stainless steel siphon to the household drainage following local plumbing codes. Use the drainer area for drying dishes and short-term food preparation; the integrated overflow will help prevent accidental overflows when the bowl is filling. Clean the granite composite surface with mild detergent and a soft cloth to maintain the matte finish and avoid abrasive cleaners or steel wool.
Usage recommendations
To prolong the appearance and performance of the granite composite surface, avoid leaving acidic substances or strongly pigmented liquids in the bowl for extended periods. Use silicone or rubber mats to protect the bottom from heavy pots and avoid dropping heavy objects directly into the sink. Periodic cleaning with non-abrasive cleaners and prompt rinsing after use will help keep the sink in good condition.
