Are Rectangular Bathroom Mirrors in Style?

If you’re planning a Perth bathroom renovation and wondering whether rectangular bathroom mirrors are outdated, you’re asking the right question—but the answer might surprise you. Yes, rectangular mirrors are absolutely still in style for 2026, and they’re not going anywhere anytime soon.

As Head of Purchasing at Ross’s, I see bathroom design trends firsthand through thousands of customer orders and industry insights. Rectangular mirrors consistently outsell all other shapes combined, and for good reason. Understanding why rectangular mirrors dominate—and which features define 2026 trends—helps you make confident renovation decisions without second-guessing your choices or chasing fleeting design fads.

This guide covers why rectangular mirrors remain the design standard, what’s actually trending in 2026 (LED integration, smart features, frameless dominance), when other shapes occasionally work better, and how to choose the right rectangular mirror type, size, and style for your specific bathroom.

Are Rectangular Bathroom Mirrors in Style in 2026?

Yes, absolutely. Rectangular bathroom mirrors remain the most popular choice for Australian bathrooms in 2026, accounting for approximately 80% of all bathroom mirror installations. This isn’t just habit—rectangular mirrors dominate because they offer unmatched versatility, functionality, and timeless appeal that transcends temporary design trends.

Why Rectangular Mirrors Dominate Design

Four key factors explain why rectangular mirrors have maintained their position as the bathroom mirror standard while other shapes have come and gone.

• Design compatibility: Rectangular mirrors complement the inherent geometry of bathrooms—rectangular vanities, tiles, shower screens, and room layouts. This shape harmony creates cohesive, intentional design rather than fighting against your bathroom’s natural lines.
• Timeless vs trendy: While round mirrors peaked in popularity around 2018-2020 and have since declined, rectangular mirrors have remained consistently popular for decades. This longevity signals a design classic rather than a passing trend.
• Professional preference: Interior designers and bathroom designers consistently specify rectangular mirrors for client projects because they work across all design styles—from ultra-modern minimalism to Hamptons coastal to traditional elegance.
• Market reality: Walk through any bathroom showroom in Perth (including ours at Ross’s), and you’ll notice rectangular mirrors outnumber all other shapes combined, typically by 4 to 1 ratios. This reflects genuine consumer preference, not marketing push.

The question isn’t whether rectangular mirrors are in style—it’s which type of rectangular mirror suits your specific bathroom.

Why Rectangular Bathroom Mirrors Remain Design Standards

Rectangular mirrors are set to dominate 2026 bathroom design for three fundamental reasons: LED technology integration, seamless compatibility with minimalist aesthetics, and practical functionality that other shapes simply can’t match.

LED Technology Integration

If you’re wondering, are LED bathroom mirrors are worth the hype, the answer is YES. The biggest reason rectangular mirrors are dominating bathroom design is LED technology integration. Modern LED mirrors are overwhelmingly rectangular because the format solves technical challenges that curved shapes can’t.

LED strips install seamlessly along straight rectangular edges, creating even backlighting or edge lighting that’s impossible to achieve with curved shapes. This technical reality drives the rectangle LED mirror format—manufacturers can integrate Bluetooth speakers, demisters, and touch controls without compromising the mirror’s clean lines. When you see a mirror with invisible electronics and perfect lighting distribution, there’s a rectangular shape making that possible.

The LED rectangle mirror delivers the seamless, floating appearance that defines contemporary minimalist bathrooms. The backlit glow eliminates the need for separate vanity lighting while creating ambient atmosphere. Instead of cluttering your bathroom with additional light fixtures, the mirror itself becomes your primary light source.

Our Miro and Kara LED ranges exemplify this trend—Bluetooth speakers for morning music, magnifiers for detailed grooming, and adjustable colour temperature all integrated invisibly into rectangular formats. These smart features work because the consistent rectangular edges provide housing space without visual disruption.

Seamless Integration for Minimalist Bathrooms

Minimalist bathroom design, which continues dominating Perth renovations in 2026, relies on rectangular geometry throughout—and rectangular bathroom mirrors integrate seamlessly into this aesthetic.

Walk into a modern minimalist bathroom, and you’ll notice every element reinforces the same linear language: rectangular vanity, rectangular tiles, rectangular shower screen, rectangular mirror. This cohesive visual flow isn’t accidental—it’s intentional design, with each element supporting the others. Introducing a round mirror into this geometry creates visual discord, at odds with the bathroom’s natural lines.

Frameless rectangular mirrors achieve the “disappearing” effect that minimalist design philosophy demands. The mirror becomes a functional surface rather than a decorative object, exactly what minimalism requires. Without frames, curves, or ornamental details, the mirror recedes visually, allowing your bathroom’s materials and finishes to take centre stage.

Rectangular mirrors align proportionally with rectangular vanities, creating a mathematical balance impossible to achieve with round or irregular shapes.

Practical Functionality

Beyond aesthetics and technology, rectangular shapes simply work better functionally.

Rectangular mirrors provide more usable mirror surface than round or oval mirrors of similar dimensions. A 900mm wide rectangular mirror delivers approximately 30% more reflection area than a 900mm diameter round mirror. That translates directly to better functionality for grooming, makeup application, and getting ready—you’re seeing more of yourself with less wasted wall space.

Rectangular mirrors utilise wall space efficiently without awkward gaps. The straight edges sit flush against walls and align with vanity edges, maximising usable reflection while minimising wasted wall area. This matters particularly in compact Perth bathrooms where every centimetre counts. A round mirror leaves triangular gaps in corners and awkward spaces that serve no purpose, while a rectangular mirror uses the full available wall space.

Current Rectangular Bathroom Mirror Trends in 2026

What’s trending isn’t the rectangular shape itself—that remains constant—but rather the features, finishes, and technologies integrated into rectangular formats.

LED Integration Dominates

Backlit LED mirrors: The fastest-growing segment in bathroom mirrors. Our Miro LED range (sizes from 750x900mm to 1500x750mm, $809-$1,479) exemplifies this trend—edge-lit or backlit designs that create a floating appearance while providing even, shadow-free illumination. The backlit glow transforms these rectangle LED mirrors from functional fixtures into ambient lighting sources that eliminate the need for separate vanity lights.

Smart LED features: Bluetooth speaker integration (Kara LED with Bluetooth $1,349-$1,539, Miro LED with Bluetooth Speaker $1,008-$1,479) lets you play morning music or podcasts without cluttering bathroom benchtops with separate devices. Touch-sensitive controls, colour temperature adjustment from warm to cool white, and demister functions are becoming standard features rather than premium extras. These smart features represent where LED rectangle mirrors are heading—integrated technology that enhances daily routines invisibly.

Magnification integration: LED mirrors with integrated magnifier sections (Miro LED with Magnifier $1,008-$1,348) combine full-length reflection with 3x magnification zones for detailed grooming. Instead of needing a separate makeup mirror, you get both functions in one rectangular format—practical elegance that solves two needs simultaneously.

Frameless Rectangles Lead

Polished edge dominance: Frameless rectangular mirrors with polished edges ($80-$180 at Ross’s) continue to dominate modern bathroom renovations. The absence of frames creates a seamless, sophisticated aesthetic that suits minimalist and contemporary styles. The polished edge catches light subtly while the mirror itself recedes visually, letting your bathroom’s design speak.

Bevelled edge elegance: Bevelled Edge Mirrors ($80-$180) offer a subtle traditional touch while maintaining frameless simplicity. The bevelled edge catches light beautifully, adding depth and visual interest without ornate framing. For bathrooms that want something beyond flat polished edges but still maintain clean lines, bevelled edges provide the perfect middle ground.

Why frameless wins: Frames date quickly—2015’s popular bronze frames now look outdated, while frameless remains perpetually modern. Frameless also showcases tiled feature walls rather than competing with them. When you’ve invested in beautiful tiles or statement walls, frameless rectangular mirrors complement rather than distract.

Larger Rectangle Sizes Trending

Maximalist mirror approach: Bigger rectangular mirrors—900x1500mm, 1200x1500mm, even floor-to-ceiling installations—reflect 2026’s “more mirror, more light” philosophy. Large rectangular mirrors make bathrooms feel significantly more spacious by bouncing light throughout the room and creating the illusion of depth. Where 2010s bathroom design favoured modest mirror sizing, 2026 embraces generous proportions.

Wide mirrors for double vanities: Perth master ensuites increasingly feature wide rectangular mirrors (1500mm+) spanning double vanities rather than two separate mirrors. This unified approach creates a luxurious, seamless appearance that makes the vanity area feel like a cohesive design statement rather than two individual stations.

Matte Black Accents (When Framed)

While frameless dominates, framed rectangular mirrors use matte black almost exclusively in 2026. Matte black frames coordinate with matte black tapware—Perth’s most popular tapware finish at the moment—creating a cohesive, modern aesthetic throughout the bathroom. The matte finish also hides water spots and fingerprints better than glossy alternatives.

What’s Declining in 2026

Round mirrors: Peaked 2018-2020, now declining except in specific vintage or statement applications. What felt fresh five years ago now feels dated.

Ornate frames: Heavy, decorative frames feel dated as minimalism’s influence means even traditional bathrooms favour simpler framing approaches.

Small mirrors: The trend toward larger mirrors means 600mm width is now considered the minimum for main bathroom vanities—anything smaller feels inadequate in 2026 design.

Perth-Specific Trends

Hamptons/coastal style: Remains hugely popular in Perth, using large frameless rectangular mirrors to bounce natural light and create an airy, beachy atmosphere. The coastal aesthetic relies on light reflection to achieve its signature bright, fresh feel.

Modern minimalism: Perth’s new home builds overwhelmingly specify frameless or LED rectangular mirrors for clean, contemporary aesthetics. Builders know buyers expect modern fixtures, and rectangular mirrors with LED integration tick that box without risk.

When to Consider Other Bathroom Mirror Shapes

Rectangular mirrors suit 80% of bathrooms, but other shapes make more sense in some cases.

Round Mirrors

• Softening angular spaces: If your bathroom features exclusively straight lines—rectangular tiles, linear drains, square fixtures—a round mirror can introduce welcome curved contrast.
• Above round vessel basins: Round above-counter basins look odd beneath rectangular mirrors. Shape echo (round basin, round mirror) creates intentional design cohesion.
• Powder room statement: Small powder rooms suit bold, round feature mirrors because these rooms prioritise visual impact over functional mirror surface.
• Vintage or art deco styling: Period bathrooms (1920s-1940s aesthetic) historically featured round mirrors, making them authentic vintage choices.

Oval Mirrors

• Traditional bathroom aesthetics: Oval mirrors complement traditional vanity cabinetry and vintage-inspired fixtures without the starkness of rectangular.
• Softening without full circles: Ovals provide curved elegance while maintaining some vertical rectangular benefits.

Arched Mirrors

• Mediterranean or Moroccan styles: Arched mirrors suit specific cultural design aesthetics, with the curved top referencing traditional architecture.
• The 80/20 Rule: Approximately 80% of bathrooms benefit most from rectangular mirrors due to versatility, functionality, and integration with rectangular fixtures. The remaining 20% have specific stylistic reasons—vintage aesthetic, curved fixtures, statement design—justifying alternative shapes. When uncertain, rectangular remains the safest, most versatile choice.

Which Rectangular Mirror Style Suits Your Bathroom?

Now that we’ve established rectangular mirrors remain stylish, here’s how to choose the right type for your Perth bathroom.

Frameless Rectangular Mirrors

• Bevelled Edge Mirrors ($80-$180): Classic frameless option with bevelled perimeter that catches light and adds subtle depth. Suits modern through to transitional styles—a budget-friendly, timeless choice that works across different bathroom aesthetics.
• Polished Edge Mirrors ($80-$180): Flat polished edge creates an ultra-minimalist appearance. Completely frameless with a disappearing aesthetic, perfect for contemporary minimalist bathrooms. Showcases feature tile walls without competing visually.
• Dunedin Mirror ($70-$280): Available in various rectangular sizes, offering the most budget-friendly entry point. Classic, simple mirror option that suits any bathroom style when you need straightforward functionality without additional features.

When to choose frameless:

• Modern or contemporary bathroom styles
• Minimalist design preference
• Want the mirror to recede visually
• Budget-conscious ($70-$280 range)
• Small bathrooms (frameless feels less cluttered)
• Have adequate lighting already

LED Rectangular Mirrors

• Kara LED Range ($999-$1,539): Available in 600x900mm and 750x1200mm sizes with backlit LED providing even illumination. Standard or Bluetooth speaker versions create a modern floating appearance while eliminating the need for separate vanity lighting.
• Miro LED Range ($809-$1,479): Extensive size options from 750x900mm through 1500x750mm. Choose from standard LED, Bluetooth speaker, or magnifier versions. Edge-lit or backlit options with demister function included—the most versatile LED range for different bathroom sizes and needs.

When to choose LED mirrors:

• Need additional bathroom lighting
• Modern luxury aesthetic
• Shadow-free grooming/makeup lighting
• Want integrated Bluetooth or magnifier
• Creating a spa-like atmosphere

Installation note: LED mirrors require a licensed electrician (Perth electrical regulations). Budget an additional $200- $400 in installation costs beyond the mirror price.

Rectangular Mirror Cabinets

Piper PVC Shaving Cabinets ($240-$480): Durable PVC construction provides moisture resistance in bathroom environments. Various size options are available, providing practical storage behind the mirror surface.

When to choose mirror cabinets:

• Small bathrooms needing storage
• Limited vanity cupboard space
• Want hidden storage for toiletries/medications
• Budget-conscious dual functionality (mirror + storage in one)

Sizing Rectangular Bathroom Mirrors Above Vanities

Proper sizing ensures your rectangular mirror looks proportional and functions effectively.

The 70-80% Rule

Standard guideline: Your rectangular mirror width should measure 70-80% of your vanity width for balanced proportions.

Examples:

• 600mm vanity → 420-480mm mirror width
• 900mm vanity → 630-720mm mirror width
• 1200mm vanity → 840-960mm mirror width
• 1500mm vanity → 1050-1200mm mirror width

Why this works: Narrower mirrors look lost above wide vanities, while wider mirrors overhang awkwardly. The 70-80% range creates visual balance that feels intentional rather than accidental.

The 1:1 Match (Modern Alternative)

Full-width approach: Match your mirror width exactly to your vanity width—e.g., a 900mm mirror above a 900mm vanity. This creates a unified, seamless appearance popular in modern minimalist bathrooms. The mirror extends to the full length of the vanity, creating visual continuity rather than traditional proportional balance.

2026 trend: Full-width matching is increasingly popular for contemporary aesthetics, particularly in new home builds.

Height Considerations

Standard heights:

• 600-800mm typical bathroom mirror heights
• 900-1200mm for taller mirrors (better for tall family members)
• 1500mm+ for dramatic floor-to-ceiling effect

Vertical placement:

• Bottom edge: 100-150mm above vanity benchtop
• Top edge: Comfortable eye level for the tallest family member
• Avoid placing so high that shorter users can’t see

For complete placement guidance, including mounting height, see our Vanity Mirror Placement Guide.

Double Vanity Sizing

Two options:

• Single wide mirror (1500-1800mm) spanning both basins
• Two separate mirrors (750-900mm each) creating symmetry

2026 trend: Single wide mirrors are increasingly popular for a unified, luxurious appearance rather than two separate mirrors.

Measuring Tips

Before purchasing rectangular bathroom mirrors:

• Measure vanity width precisely
• Note any light switches, outlets, or obstacles on wall
• Account for tap clearance (avoid water splashing mirror bottom)
• Consider existing lighting placement

The Verdict: Rectangular Mirrors Dominate 2026 and Beyond
