    Flawlessly crafted from one solid material accommodating both deck and wall-mounted taps.

    The modular award-winning Monolith M Series is a solid surface sink. With a continuous trough and a shallow rear deck, it’s ideal for either wall-mounted or deck-mounted fixtures.  The minimalist basin accommodates one to multiple user stations within the integrated enclosure. The seamless angled basin leads to a discreet water channel along the rear face. Incorporating a perfectly proportioned drainage hole, while the tight radius corners complement the outer face of the sink.

    Usually, a monolith is just one solid piece of stone. We’ve added a few finishing touches.

    Key features

    Fast installation
    The modular steel bracket system is fixed to the wall. The basin then slides in and is held via an incredibly strong tab and bolt method.  This vastly speeds up the installation and reduces installation costs.

    Minimal maintenance
    The solid-surface material will not break down due to moisture, humidity or temperature changes in the washroom, which reduces repairs and maintenance.

    10-year warranty
    The quality of our craftsmanship, the simplicity of the system and the durability of our materials give us the confidence to offer a 10-years warranty on the Monolith System.

    A winner in the DBA Design Effectiveness Awards in the Product category.

    We don’t use materials that will warp or rot, avoiding both short and long-term issues with installations. The Monolith system is fabricated from 100% solid-surface material, supported by a proprietary modular steel bracket system.

    Large colour choice
    The Monolith is crafted from solid surface material, with over 100 finishes available from multiple solid-surface brands.

    Compliant drainage
    The Monolith system uses a slimline removable plastic drainage funnel for ease of maintenance and routine cleaning, ensuring it is fully Part H compliant.

    The original
    Developed, tested, iterated and proven for nearly a decade, the Monolith System was the first visually minimal, solid-surface basin of its kind.

    Complete customisation
    The Monolith is able to be customised to suit any washroom by accommodating multiple users in a variety of colourways shapes and sizes.


    The Monolith has been redeveloped, rebranded and refined, resulting in a hand-washing experience with nothing superfluous and nothing missing.

    How it works
    The modular units in the Monolith can be configured to suit the individual requirements of any project, specified in modules and built in one piece.

    Meet the makers
    A skilled team of production experts and master craftsmen are behind the creation of each unit in the Monolith Basin System.


    The Monolith Basin System can be quickly and easily installed by one trade with no on-site joinery.

    Step 1
    Align and fix brackets to the wall.

    Step 2
    Align the Monolith and secure with bolts.

    Step 3
    Connect pipework to the drainage funnel.


    Service and maintenance

    One of the benefits of installing the Monolith Basin System is the minimal maintenance required. The homogenous nature of solid-surface material allows any scuffs or scratches to simply be sanded out and should the basin ever get damaged; it can be repaired easily and quickly, making it look as good as new. For general cleaning, a product like Bar Keepers Friend works well to keep your Monolith system in top condition.
