304 Stainless Steel Courtyard Floor Drain with 15x15cm Grating for Garden and Patio Water Runoff

Managing rainwater and surface runoff in paved outdoor areas requires a drain that can withstand constant exposure to the elements while effectively channelling water. This courtyard floor drain is constructed from 304 stainless steel, a material selected for its resistance to corrosion, making it a practical choice for gardens, patios, and pathways. The square 15cm by 15cm grating provides a sufficient opening for water to enter, and the unit includes an internal ABS plastic core. Finished in a gun grey colour, it is designed to integrate discreetly with concrete, stone, or composite landscaping materials. Supplied as a single unit, it offers a straightforward drainage solution for domestic outdoor spaces.
Features and Construction

The drain's design focuses on durability and functionality for external environments. Its construction combines metal and plastic components to handle water flow and resist weathering.
Material and Build
The primary material is 304 stainless steel, which provides a robust and rust-resistant frame for the drain body and grating. This grade of steel is commonly used in applications requiring good corrosion resistance, such as outdoor fixtures. Inside the assembly is an ABS plastic core. ABS (Acrylonitrile Butadiene Styrene) is a tough thermoplastic often used in piping and drainage systems due to its strength and impact resistance, helping to guide water efficiently through the drain.
Size and Practical Fit
The drain features a square grating measuring 15 centimetres on each side. This 15x15cm dimension determines the surface area open to water entry and should be considered when planning the cut-out in your patio slabs or courtyard paving. The overall profile depth or height of the unit is not specified, so checking the required installation depth for your specific setup is advised. The gun grey finish is intended to offer a neutral appearance that matches common grey concrete or stonework.
Uses and Placement

This drain is suited for various residential outdoor settings where effective water management is needed to prevent flooding or slippery surfaces.
Event or Professional Use
For garden landscapers or property maintenance professionals, this drain provides a standardised, durable component for installation in client patios, courtyard renovations, or pathway projects. Its stainless steel construction ensures it remains serviceable over time with minimal maintenance, which is a practical consideration for landscaped areas that need to retain their appearance and function.
Everyday Home Use
Homeowners can use this drain in DIY garden projects, such as installing a new paved seating area, creating a garden path, or improving drainage around a shed or garage. Its simple, single-unit supply means it can be incorporated into existing drainage runs or new installations where a point drain is required to collect surface water from a specific zone.
Benefits and Buying Value

The value of this product lies in its material choice and straightforward design for a specific outdoor application.
Reuse and Low Maintenance
The 304 stainless steel construction is chosen for its longevity in wet conditions, meaning the drain should not need frequent replacement due to rust. The ABS plastic core is also resistant to water degradation. Maintenance primarily involves keeping the grating clear of leaves and mud, which can be done with a brush or by hand, requiring no specialist cleaning agents or procedures.
Why Choose This Product
Select this courtyard floor drain if you need a corrosion-resistant, heavy-duty drainage point for an outdoor paved area. Its specified 304 stainless steel material and 15x15cm size offer clear parameters for planning. The inclusion of the ABS core is a stated feature that contributes to the drain's function.
