🔧 Understanding the Difference: Standard vs Upgraded System

At Custom Basins, every unit comes with hot and cold water as standard, but we also offer an upgraded system for clients who want greater flexibility and a more premium setup.

✅ Standard System (Included with All Units)

Our standard water system is efficient, reliable, and designed for plug-and-play convenience.

  • Uses our automatic water pump for smooth operation

  • Hot and cold water are delivered via a direct connection to a fast-heating tap

  • No need to select or install a separate mixer tap – everything is built-in and ready to use

  • Ideal for those looking for a quick, functional solution with minimal setup

  • Compatible only with the tap included (mixer taps are not compatible with this system)

🔧 Upgraded System (Optional Add-On)

Perfect for clients wanting a custom look or higher-spec components.

  • Also powered by our automatic water pump

  • Features separate cold and hot water feeds, heated using an instant water heater

  • Allows you to choose any mixer tap (compatible with your basin size)

  • Great for matching taps to interior themes – pick your preferred colour, shape, or finish

  • Offers more flexibility and a more refined user experience
