400 mm Vanity Unit – Compact, Self-Contained & Ready to Use

The 400 mm unit is our most space-saving solution, perfect for tight areas where functionality can’t be compromised. With a sleek & colourful matte finish and a compact footprint, it still offers a practical basin and generous 5L water containers for both hot and cold water use.

Hot and cold water come as standard - no upgrades required to get started. These units come as standard with our upgraded system and mixer tap pictured.

How the non-plumbed system works

Fresh water is stored in a clean-water container. The automatic pump draws water through the selected heating/tap system to provide running water at the basin. Used water drains into a separate waste-water container, which is removed and emptied appropriately. The non-plumbed configuration does not require a permanent mains-water feed or fixed waste connection.

Power

The electrical requirements depend on the selected Standard, Upgraded or Sensor configuration. Heating components are high-load appliances, so use the stated product specification and make sure the socket, circuit and protective devices are suitable. If you are unsure, have the proposed supply checked by a competent electrician before use. Do not assume that every socket or circuit is suitable simply because a UK plug is fitted.

Water capacity & use

Container size and quantity vary by product. Runtime per fill depends on the selected container capacity, water flow and how the unit is used, so we do not quote a fixed number of handwashes per fill. Refill the clean-water container and empty the waste container as required.
