Finding the Right Under Sink Cabinet for Your UK Bathroom in 2026

By Joybuy Product Recommendation Officer Published: 07 June 2026

That awkward, unused space beneath the bathroom sink can quickly become a magnet for clutter. For many UK homes, especially those with traditional pedestal sinks, finding a practical storage solution feels like an impossible task. Bottles, cleaning supplies and spare loo rolls often end up piled on the floor or crowding the limited surface space.

This guide is designed to help you reclaim that area. We will walk through the key considerations for choosing an under sink cabinet that fits your space and needs. We will also highlight a couple of our recommended models that offer a straightforward solution to common bathroom storage problems.

How to Choose the Right Bathroom Storage Unit

Before adding any item to your basket, taking a moment to assess your needs can save you time and prevent a frustrating return. Here are a few practical points to consider.

1. Measure Your Space Accurately

The most critical step is measuring. A cabinet that doesn’t fit is of no use. Get a tape measure and note down these three key dimensions:

  • Available Width: The total space you have from side to side.
  • Available Depth: The space from the front of the sink's pedestal to the wall (or as far out as you want the cabinet to extend).
  • Pedestal and Pipework: Measure the width and depth of the pedestal itself. Most pedestal sink storage cabinet models feature a U-shaped cut-out at the back to accommodate this, but you must ensure the opening is large enough for your specific sink.

2. Match Storage Type to Your Items

Consider what you need to store. Are you battling a mountain of tall shampoo bottles and cleaning sprays, or is your main issue the clutter of smaller items like cotton pads and soaps?

  • Cabinets with Doors: These are ideal for hiding away less sightly items like cleaning products and extra loo rolls. Look for models with an adjustable internal shelf to accommodate items of varying heights.
  • Under Sink Storage with Drawers: Drawers are excellent for organising smaller toiletries and cosmetics, keeping them tidy and easily accessible.
  • A combination of both often provides the most flexible solution for a typical family bathroom.

3. Select Materials Suited for a Bathroom

The bathroom is a high-moisture environment, so material choice is important for longevity. Look for a freestanding bathroom cabinet made from materials like MDF (Medium Density Fibreboard) or particleboard with a water-resistant finish. These materials are durable, easy to clean and hold up well against the humidity, preventing swelling or warping over time. Also, check for safety features like an included anti-tip kit, which is essential for securing the unit to the wall.

Looking for a Different Style or a Complete Vanity Unit?

A freestanding under sink cabinet is a brilliant, cost-effective way to add storage without a full renovation. However, if you are planning a larger update or have a different type of sink, you might be interested in a fully integrated small bathroom vanity. These units combine a basin and storage into one seamless piece.

Frequently Asked Questions

1. How do I measure for an under sink cabinet? To ensure a good fit, measure the width of the available floor space, the depth from the wall to where you want the cabinet to sit and the height from the floor to the underside of your sink basin. Most importantly, measure the width and depth of the sink's pedestal to ensure the cabinet's U-shaped cut-out will fit around it.

2. Are under sink cabinets difficult to assemble? Most are designed for home assembly. The models we've highlighted, for example, come as flat-packs with numbered parts and detailed instructions. With basic tools and a little time, assembly is a manageable DIY project for one person.

3. Can you put any cabinet under a sink? No, you need a cabinet specifically designed for this purpose. A standard cabinet will not fit due to the plumbing and, in many cases, the pedestal. A proper pedestal sink storage cabinet has a U-shaped opening at the back to neatly slot around these obstructions, maximising the available storage space.
