Single Bowl Kitchen Sinks: Complete 2026 UK Buying Guide

A single bowl kitchen sink remains one of the most practical choices for UK kitchens in 2026 — especially in the compact and mid-size layouts that make up most homes. A single, larger basin gives you more usable space for oversized pans and baking trays than a divided bowl, drains faster, and fits worktops where a double bowl simply won't. Below we look at five real single bowl sinks currently in stock at Ultra Bathroom, all from Ukinox, a specialist stainless steel sink manufacturer, and how to choose between them.

• Ukinox Micro Series ME 400 — 400×440mm, from £108, a practical inset option for standard 600mm base units.
• Ukinox Micro Series ME 340.340 — a compact 380×380mm square bowl from £77, well suited to utility rooms or small galley kitchens.

How to Choose the Right Single Bowl Sink

Start by measuring your base unit width and the cut-out already in your worktop, if you're replacing an existing sink — most single bowl sinks are designed to drop into a standard 600mm cabinet. Decide between undermount, which sits below a solid worktop for a cleaner look and easier cleaning, and inset (top-mount), which is quicker to fit and works with laminate worktops. Check whether you need a specific drainer position — the Micro Master range offers a left or right option, which matters if your sink sits next to a hob or window. Finally, polished stainless steel is easier to keep looking new day-to-day, while a heavier gauge steel resists dents better in a busy family kitchen.
