When planning a remodel, choosing the right kitchen sink unit can transform both the look and function of your kitchen. With 20 years of expertise in the UK kitchen industry, we will explain what a sink unit includes, which styles to consider, and how to maximise the space beneath it.
What is a kitchen sink unit?
A kitchen sink unit refers to the sink itself along with the base cabinet that houses it. This part of the kitchen handles daily washing, rinsing and waste, while also providing storage. Choosing the right combination of sink and cabinet will improve workflow, hygiene and design consistency.

Why the sink unit matters in your layout
