Both discreet and striking, this sink has real feeling.

The Monolith is a modular solid surface trough sink designed for use with wall-mounted fixtures. The minimalist basin accommodates from one to many user stations within the integrated enclosure. The angled basin leads to a discreet channel along the rear face and incorporates the drainage hole, while tight radius corners complement the outer face of the sink.

Optional pipeskirts can be specified, with two designs (squared or angled) available in stainless steel, black, or white powder coat. Configure your Monolith using the drop-down menus on this page. Optional side caps for pipeskirts can be specified where necessary.

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

Key features

Fast installation
As there is no timber framework required, the Monolith System can be fitted by one trade, namely the M & E contractor, rather than requiring joinery. This speeds up 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 gives us the confidence to offer a 10-year warranty on the Monolith System.

Award winning
Bronze winner in the 2014 DBA Design Effectiveness Awards in the Product category.

Unlike many solid-surface basins that are backed with an MDF or plywood substrate and supported with a timber framework, the Monolith system is fabricated from 100% solid-surface material, supported by a proprietary steel bracket system, making it impossible to rot or break down.

Large colour choice
The Monolith System is crafted from HI-MACS® or CORIAN®, the two market leaders in solid surface material. Available in 100s colours. Other solid-surface materials are also available.

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.


In a collaboration with Factory Design, the Monolith Basin System 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 Basin System can be configured to suit the individual requirements of any project. Specified in modules, 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.

Specify your basin system

Outside of the washroom a monolith normally means something that is slow or unwilling to change. However, our Monolith is easily customisable to suit the needs of your project and we designed this system to make your vision easy to achieve. We offer two types of Monolith modules: standard basins and customised basins.

Standard basin

All standard sizes are available for immediate download. Just select the required size to download a specification pack including CAD, parametric revit models and a datasheet.

Customised basins

For custom sizes and additional modules, click any options you are interested in, include desired sizes in the form and our dedicated planners will create you a project-specific model within two working days. For inspiration, view our product gallery at the top of the page.


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.



Our Monolith Basin System is infinitely configurable. The flexibility of our solid-surface material, its ability to be seamlessly jointed and the modularly designed units allows the specifier thousands of possibilities to meet the needs of their project.

From a single-user basin through to L-shaped basins with coved corners, bin chutes and more, our versatile system can adapt to your requirements: colour samples, full-basin cut-throughs and even a full mock-up service are available to help ensure your project achieves the best result.

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.
