Courtyard floor drain constructed from 304 stainless steel featuring an ABS plastic drainage core with a gun grey finish and a 15cm x 15cm grating size for outdoor waste water management
304 Stainless Steel Courtyard Floor Drain with 15x15cm Gun Grey Grating

Managing surface water in gardens, driveways, and patios requires a drain that can handle weather exposure while providing reliable performance. This courtyard floor drain meets that need with a construction centred on 304-grade stainless steel, a material chosen for its resistance to rust and corrosion. The unit features a precise 15 centimetre by 15 centimetre grating, finished in a gun grey colour, designed to sit flush with paved or concrete surfaces. Its practical design incorporates an ABS plastic core to channel water efficiently, making it a straightforward solution for integrating into existing outdoor drainage setups where durability and a clean finish are priorities.
Features and Construction

This drain's design focuses on material longevity and functional simplicity for outdoor waste water management. The key components are selected for their suitability in exposed environments, ensuring the product performs its core task effectively over time without requiring complex maintenance.
Material and Build
The primary structure is crafted from 304 stainless steel, an alloy containing chromium and nickel that provides a well-established defence against corrosion, making it a practical choice for metal fixtures in damp, outdoor conditions. The surface grating receives a gun grey finish, which contributes to its visual profile. Internally, the drainage pathway is formed by a core made from ABS plastic, a material noted for its good impact strength and resistance to degradation from water, ensuring the internal water channel remains intact.
Size and Practical Fit
The drain's visible surface is defined by its grating dimensions of 15cm x 15cm. This measurement determines the size of the opening required in your courtyard surface for installation and the coverage area over the drainage point. This specific size indicates it is intended for standard single-outlet drainage applications in residential outdoor settings, rather than for large-scale commercial channels.
Uses and Placement

Focused on residential and light commercial outdoor areas, this drain serves a clear purpose in water runoff management. Its application is guided by its stated specifications, fitting seamlessly into projects where a discrete and durable drainage point is needed.
Event or Professional Use
For garden landscapers, property maintenance teams, or builders, this drain offers a standardised, corrosion-resistant component for completing outdoor hardscaping projects. Its 304 stainless steel build means it can be specified for installations where material longevity is a factor, such as around swimming pool surrounds, in commercial patio areas, or within public garden pathways, providing a reliable finish that withstands public use and weather.
Everyday Home Use
Homeowners can integrate this drain into DIY projects or professional installations for driveways, garden patios, or alongside garage entrances to prevent standing water. The 15x15cm size suits typical downpipe runoff areas or spots in paving where water collects. The gun grey finish allows it to blend with many concrete or stone finishes, while the stainless steel construction ensures it does not deteriorate quickly with seasonal changes.
Benefits and Buying Value

The value of this courtyard drain lies in the practical advantages delivered by its specified materials and dimensions. It addresses common concerns about outdoor fittings without relying on invented claims about performance or lifespan.
Reuse and Low Maintenance
The corrosion-resistant nature of 304 stainless steel suggests a product that is less likely to need replacement due to rust-related failure, supporting its potential for long-term use. The ABS plastic core is also resistant to water degradation. Maintenance is straightforward, typically involving the occasional removal of leaves or debris from the grating surface, a simple task compatible with the materials' cleanability.
Why Choose This Product
Selecting this drain means opting for a product where the material choices—304 stainless steel and ABS plastic—are directly aligned with the demands of an outdoor drainage application. The clear 15x15cm dimension allows for accurate planning and installation. It provides a factual, specification-led option for buyers who prioritise known material properties and a defined size over vague promises of quality or style.
