Choosing Floor Box Finishes: Brass, Bronze and Stainless Steel for Design-Led Interiors

When specifying floor boxes for a design-led interior, the finish is one of the few details that gets touched, seen up close and lived with every day. Get it wrong and a beautifully specified floor is undermined by a mismatched flap and handle. Get it right, and the finish quietly reinforces the material palette the architect or interior designer has spent months curating. In this article, we compare brass floor boxes and stainless steel floor boxes to help you choose the right finish for your next project.

For anyone specifying power, data or AV access in a residential or hospitality scheme, the choice usually comes down to two families of finish: warm metals such as brass and bronze, and cool metals such as stainless steel. Both are available as standard across our range, and the choice can carry a design scheme in very different directions.

Why floor box finish matters more than you’d think

Our floor boxes are designed so that as little as 10% of the metal lid is visible once installed, keeping the floor covering itself as the focal point of the room. That sounds like a reason not to worry too much about finish. In practice, it’s the opposite. When so little metal is on show, the small amount that is visible has to work harder, and it sits directly alongside other architectural hardware, including:

• Door/window furniture
• Wall switches
• Lighting hardware
• Curtain poles

Any inconsistency between the floor box finish and this surrounding hardware is immediately obvious, in a way that a larger surface area would forgive. This is why we treat finish selection as a genuine part of the specification conversation rather than an afterthought, and why architects and interior designers are increasingly treating floor boxes as another piece of architectural hardware to be coordinated, not a purely functional fitting to be hidden.

Brass floor boxes: warmth and character that ages well

Brass has had a long run as the default warm metal in high-end interiors, and current design commentary suggests it isn’t going anywhere, even as cooler tones like chrome and nickel have their own moment in the spotlight. What’s changed is the way brass is being specified. Rather than a single uniform brass finish used everywhere, designers are layering it against other materials and metals to add depth.

We offer brass floor boxes as part of our ELEGANT Finishes range, in four distinct options:

• Satin brushed brass – a lightly textured, brushed finish that balances warmth with restraint. It works equally well in a contemporary scheme with oak and stone as it does in a more traditional interior.
• Mirror-polished brass – a high-shine, opulent finish best suited to low-traffic areas, where it can sit alongside gold fixtures and lighting without picking up excessive wear.
• Antique brass – a matte, aged finish with a period character, well suited to schemes that lean into Victorian or heritage colour palettes.
• Antique bronze– darker, richer tones for interiors that want warmth without the brightness of a true brass finish.
• Jordan bronze – Suits an industrial-chic aesthetic, contrasting well against cooler, edgier design intent.

 

 

Brass and its bronze variants are also “living” finishes: they develop a natural patina with handling and age, something a growing number of clients are actively requesting rather than trying to avoid. If a project is aiming for a considered, lived-in feel rather than a showroom-fresh one, it’s worth flagging this to the client early, since it’s very much a deliberate design choice made available in the 700 series and Minima ranges.

Stainless steel floor boxes: precision for contemporary and mixed-metal schemes

Where brass brings warmth, stainless steel brings precision. It’s the finish of choice for interiors built around a cooler material palette, chrome or nickel-based hardware, or a more industrial aesthetic.

Our stainless steel floor boxes come in three finishes:

• Satin brushed stainless steel – a matt, brushed finish with good resistance to fingerprints, giving it a practical edge in higher-traffic commercial and residential settings alongside its contemporary look.
• Mirror-polished stainless steel – a lustrous, reflective finish that pairs naturally with chrome or nickel fixtures, though as with mirror-polished brass, it’s best specified for low-traffic areas where the finish won’t be dulled by regular foot traffic.
• RAL powder coated – applied over a stainless steel base in the same way a lacquer coat protects and finishes brass, powder coating gives a durable, colour-fast finish in any RAL colour, opening up a far wider palette than the metal tones alone. It’s a genuinely useful route when a scheme calls for a specific accent colour rather than a warm or cool metal and we showcase a number of standard RAL colour options that are currently popular.
• Stainless steel tends to be the safer specification choice where the finish needs to read as neutral rather than make a statement, for example alongside a busy floor pattern or a strong accent colour elsewhere in the room.

Brass or stainless steel? It often comes down to what’s already in the room

Rather than choosing a floor box finish in isolation, we’d always recommend treating it as the last piece of an existing hardware puzzle. A few starting points:

• Classic and heritage interiors with rich, deep colour schemes tend to suit brass, which combines practicality with a sense of timeless charm.
• Industrial-inspired designs that blend rugged materials with modern lines often call for a warm metallic finish such as Antique brass or Jordan bronze, to soften an otherwise hard material palette.
• Refined, minimalist spaces built around high-quality materials and a restrained colour palette generally favour stainless steel, particularly where chrome or nickel hardware is already specified.
• Open-plan living and office spaces with bifold or Crittall-style doors and windows often look best when the floor box finish aligns with that existing metalwork.

It’s also increasingly common, and design-forward, to mix finishes deliberately across a scheme rather than matching everything. A brushed brass floor box can sit comfortably in a room with satin nickel switches or a darker ironmongery finish, provided the mix feels intentional rather than incidental. If you’re specifying for a client who’s nervous about mixing metals, it’s worth reassuring them that this is now standard practice in considered interiors, not a compromise.

Practical specification points worth flagging to clients

A few details are easy to miss at specification stage but matter once the floor box is installed:

• Finish is applied to critical faces only – the lid, lid frame, handles and flaps, so the finish shows at its best while the mechanism continues to operate correctly over its lifetime.
• Mirror finishes are best reserved for low-traffic areas. Both mirror-polished brass and mirror-polished stainless steel will show wear more readily underfoot than a satin finish.
• Satin brass and satin stainless steel are our standard finishes, with antique brass, antique bronze and Jordan bronze available as specialist finishes to match a specific interior scheme.
• All finishes are hand-finished in the UK, which allows for a level of consistency and quality control that’s harder to guarantee with mass-produced alternatives.

Specifying the right finish for your project

As you can see, whether a project calls for the warmth of a brass floor box, the industrial edge of Jordan bronze, or the precision of a stainless steel finish, the goal is the same: a detail that disappears into the design rather than fighting it.
