How to Choose the Right Mirror Cabinet for Your Toilet or Washroom

It might surprise you, but a toilet mirror cabinet can completely transform a small washroom or toilet. Beyond giving you a handy spot for last-minute touch-ups, it adds valuable storage in compact spaces where every centimetre counts.

A toilet mirror cabinet — sometimes called a mirror cabinet for toilet or powder rooms — is a compact, wall-mounted storage unit that fits neatly over a toilet or basin. It combines reflection and practicality, keeping essentials like toiletries, tissues, and cleaning products out of sight but within reach.

While many people think of traditional bathroom mirror cabinets, these smaller, slimmer options are ideal for tight spaces like powder rooms or guest toilets. They instantly make the room feel larger, brighter, and more organised.

Ross’s Discount Home Centre offers a quality range of toilet and washroom mirror cabinets built for Perth homes — featuring durable, moisture-resistant materials, adjustable shelving, and sleek, modern finishes. In this guide, we’ll show you how to choose the right size, style, and placement to make your compact space work beautifully.

Why Add a Mirror Cabinet Above the Toilet

Adding a mirror cabinet above toilet cisterns is one of the simplest ways to elevate both the look and functionality of a small bathroom or washroom. A toilet mirror cabinet serves a dual purpose — it’s a discreet storage solution and a clever design feature that enhances light and space.

These compact wall-mounted units are perfect for keeping everyday essentials out of sight while maintaining a clean, organised look. Toiletries, tissues, and cleaning products can all be stored neatly behind mirrored doors, reducing clutter on open shelves or benchtops. The result is a more streamlined and modern appearance — ideal for contemporary homes where every detail counts.

From a design perspective, a wall mirror cabinet for toilet areas also creates the illusion of space. The reflective surface bounces natural and artificial light around the room, making narrow or windowless areas feel brighter and more open. In smaller layouts, such as guest washrooms or powder rooms without a vanity, this can make a noticeable difference.

Practical and stylish, a toilet mirror cabinet offers the best of both worlds — functional storage that doesn’t compromise aesthetics.

Choosing the Right Size & Height

Choosing the right mirror cabinet above the toilet is all about achieving balance — it should look proportionate, feel comfortable to use, and fit safely within your available wall space.

Measure the Space

Start by measuring the wall area between the top of your toilet cistern and the ceiling. Most toilet mirror storage designs fit within this zone, but measuring first helps avoid crowding.
Also check the horizontal clearance — the cabinet should align with or be slightly narrower than the toilet for a balanced look.

Pick the Right Depth

For compact bathrooms, opt for a shallow toilet mirror with storage (around 120–150 mm deep). Slim designs prevent bumping hazards and keep small spaces feeling open and tidy.

Choose the Best Width

In narrow toilets or washrooms, single-door or slimline double-door cabinets work best. They offer practical toilet wall cabinet storage without overwhelming the wall.

Look for Adjustable Shelves

Cabinets like the Natasha or Piper ranges feature adjustable shelves, perfect for tailoring storage to different toiletries and cleaning products.

Prioritise Safety

Before installation, check for electrical points, switches, or plumbing lines behind the wall. Leave enough space for full door swing and safe daily use.

A well-measured, wall-mounted mirror cabinet can transform unused space above the toilet into functional, stylish storage — smart, safe, and beautifully efficient.

Design & Style Tips for Toilets and Washrooms

A well-chosen toilet or washroom mirror cabinet can do more than just store essentials — it can completely transform the look and feel of a compact space. Whether you’re styling a new build or refreshing a small toilet, the right design creates cohesion and visual balance.

Match Finishes for Continuity

If your toilet or washroom connects to a main bathroom, aim to match finishes across both spaces. Choose a toilet mirror cabinet design that complements nearby vanity units, tiles, and tapware for a unified look. For instance, pair a white gloss cabinet with light wall tiles for a crisp, modern effect, or coordinate brushed-nickel hardware with similar tapware for subtle harmony.

Add Shape and Personality

Curved or round mirror cabinets — like the Natasha Arch and Natasha Round — soften sharp lines in tight layouts and create a striking focal point. Rounded shapes are especially effective in minimalist powder-room designs where every detail matters.

Play with Colour and Contrast

Colour dramatically changes the mood of small rooms. White cabinets help reflect light and keep things bright, while black or charcoal-framed designs add bold contrast for a contemporary edge. If your tiles already feature texture or pattern, a frameless cabinet balances the look.

Keep It Minimal and Light

Slimline or frameless mirror cabinets work best in very compact spaces. Their clean silhouettes amplify light — particularly when positioned opposite a small window or beneath a pendant fixture. You can also compare bathroom mirrors vs mirrored shaving cabinets to find the best style for your room.

A thoughtfully styled toilet mirror cabinet ties the entire space together — functional, elegant, and perfectly proportioned for modern Perth homes.

Installation Tips & Safety Considerations

Proper mirror cabinet installation is essential for both safety and long-term performance — especially in compact areas like washrooms, powder rooms or toilets. A few careful steps can make your new cabinet secure, functional, and built to last.

Check Height and Clearance

Start by confirming there’s enough space above the toilet or concealed cistern. Position the cabinet so it sits at a comfortable eye level, usually 30–40 cm above the cistern lid. This provides clear reflection, safe clearance for the flush button, and enough room for doors to open fully.

Use Correct Fixing Points

Always mount your cabinet on solid wall studs or use high-quality anchors suitable for tiled walls. This ensures safe wall mounting and prevents damage from weight or vibration over time. When drilling through tiles, use a ceramic bit and work slowly to avoid cracks.

Consider Moisture and Ventilation

Bathrooms and washrooms naturally experience humidity, so ventilation is key. Good airflow prevents fogging and protects the cabinet’s finish. Ross’s toilet mirror cabinets are made from moisture-resistant PVC, designed to withstand Perth’s humid conditions and stay looking new for years.

Keep Electrical Points Clear

Avoid installing near electrical outlets, switches, or exposed wiring. If you plan to add lighting above or beside your powder-room mirror cabinet, ensure it meets IP-rated bathroom safety standards.

Choose Quality and Maintenance Ease

All Ross’s cabinets are lightweight, durable, and easy to clean — ideal for busy Perth homes. Regularly check fittings and hinges to keep everything aligned and secure.

A correctly installed mirror cabinet not only enhances convenience and style but also guarantees long-term safety and stability in your bathroom, toilet, or powder room.
