Sturdy, durable, practical, and stylish - the Grohe K400 composite sink with user-friendly 1.5 bowls meets all these criteria. The 1.5 bowl sink with a draining board for installation on the countertop (116 x 50 cm) has the advantage of being usable from both sides. It is made from 80% quartz, 20% acrylic resin, and hardening composite material, making it resistant to stains, scratches, heat, and dents. The main bowl has a generous interior depth of 20.5 cm. The seamlessly cast flawless surface is easy to clean, low-maintenance, and 100% food hygienic. The elegant, contemporary surface in Granite Black does not react to UV light and retains its deep color even after years of use. Thanks to Grohe Whisper technology, the composite construction is extremely quiet under running water. The automatic waste water drain features a stylish round actuator and is operated by a remote control. The drain is operated from the outside, eliminating the need to reach into dirty wastewater to pull the plug. The Grohe QuickFix system has 2 pre-punched holes, making installation quick and straightforward. This sink can also be upgraded with an intelligent Grohe actuator.
