The New Rules of Hardware: When to Mix and When to Match Metal Finishes 

Designers have long understood the power of hardware — those seemingly small details that quietly shape a space’s personality. But as interiors become more layered, expressive, and personal, one design decision is rising to the forefront: when to mix metal finishes — and when to match. 

Once seen as a design risk, mixing metals is now emerging as a way to create depth and contrast — an opportunity to introduce tension without losing cohesion. 

“Mixing metals has always been part of design,” says Rosanne Spagnolo, interior designer and Castella hardware specialist. “But now it’s less about rules and more about instinct — knowing when to blend and when to make a statement.” 

So how do you know which approach is right for your space? Understanding the role each finish plays — whether as a supporting act or a standout feature — is key to getting the balance right. 

Why Designers Are Embracing Mixed Metals 

For decades, hardware finishes were often chosen to match. Chrome taps were paired with chrome handles, brushed brass paired with brass fittings — neat, consistent, and deliberate. 

But as modern interiors have shifted toward more curated, layered spaces, designers have become bolder in their approach. Today, mixing metals is a deliberate design choice — a way to introduce depth, tactility, and contrast. 

“It’s a way to make a space feel more personal,” says Rosanne. “When you introduce contrast — like pairing brushed brass handles with a matte black tap — it stops a kitchen or bathroom from feeling one-note.” 

When done well, mixed finishes feel less like a design decision and more like an expression of character — the kind of detail that makes a space feel lived-in and effortlessly stylish. 

When to Mix Metals (And How to Do It Well) 

The secret to mixing metals is knowing where to create contrast — and where to pull things back. 

Create a Hero Finish 

The key to keeping mixed metals feeling intentional is choosing one dominant finish — the metal that sets the tone for the space. Think brushed brass handles as the lead character, with smaller accents in polished nickel or matte black to add a layer of contrast. 

“Your hero finish is the foundation,” says Rosanne. “It’s the finish that appears most often, so let that anchor the design — then use your secondary metal as an accent.” 

Play with Texture and Sheen 

Mixing metals doesn’t always mean pairing gold with silver — it can be as simple as combining polished and brushed variations of the same finish. 

“Brushed brass handles paired with a polished brass tap creates a subtle contrast that feels rich and layered,” Rosanne explains. “It’s a softer way to introduce variety without overcomplicating things.” 

Repeat for Rhythm 

The most successful designs repeat their chosen finishes throughout the space. If you’ve introduced a brushed brass handle on your cabinetry, echo it in smaller details like a brass pendant light, towel hook, or shelving bracket. 

“Repetition is what makes mixed metals feel intentional,” says Rosanne. “It ties the whole design together.” 

When Matching Finishes is the Stronger Choice 

For all the impact mixed metals can bring, there are moments when sticking to a single finish feels stronger — more refined, intentional, and timeless. 

“Matching finishes creates this beautiful sense of calm,” says Rosanne. “It’s a simpler approach, but when done well, it feels incredibly elevated.” 

In smaller spaces, like compact kitchens, laundries, or powder rooms, uniform finishes can reduce visual clutter — creating a sense of openness and flow. 

“When a space is tight, too many competing finishes can feel busy,” Rosanne explains. “Keeping everything consistent gives the room room to breathe.” 

Matching metals is also a smart choice when the space itself makes a strong statement. 

“If you’re working with bold marble veining, richly grained timber, or deeply coloured cabinetry, matching finishes allow those elements to take the lead,” Rosanne says. 

And when it comes to creating a timeless look? Rosanne leans toward consistency. 

“For heritage-inspired interiors, or spaces designed to feel classic and enduring, a single finish — like aged brass or antique bronze — gives that sense of quiet elegance that never dates.” 

Ultimately, Rosanne believes the choice to mix or match comes down to one simple principle: know what you want to stand out. 

“If your materials are the feature, let your hardware support them,” she says. “But if you’re using hardware to create impact, that’s where you can really push the contrast.” 

Finding Balance in the Details 

Balance is key — whether you choose to mix or match. And Rosanne believes the best way to create that sense of balance is by focusing on the most frequently touched details. 

“Hardware, taps, and towel rails are the touchpoints of a space,” she explains. “Choosing warm metals for these elements — like brushed brass or bronze — makes the space feel grounded and inviting.” 

For designers wanting to mix metals, Rosanne suggests keeping contrast controlled by grouping similar finishes in specific areas — for example, using brushed brass handles on cabinetry while reserving matte black for lighting or a bold statement tap. 

“It’s about creating contrast with purpose,” she says. “When metals are layered thoughtfully, they add rhythm and richness to a space without feeling chaotic.” 

The Art of Mixing with Intention 

Hardware may seem like a small detail — but the right combination of finishes can define the entire mood of a space. 

“Mixing metals should feel instinctive,” says Rosanne. “It’s about layering warmth and texture in a way that makes the whole space feel richer.” 

In the end, whether you choose to mix or match, the goal isn’t just visual impact — it’s about creating a space that feels calm, balanced, and unmistakably yours.
