Whether you're crafting a modern masterpiece, embracing vintage charm, or blending transitional styles, your choice of mirror will be a key element in tying the entire theme together.

In this guide, we'll dive into the process of selecting a bathroom mirror, looking at everything from style and shape to practical considerations like size and placement. By the end, you'll have all the insights you need to confidently choose the perfect mirror for any bathroom project.

1. Style: Finding the Right Mirror to Match the Room’s Aesthetic

Before anything else, the first question to ask is: What style are you going for in this bathroom? The mirror should complement the overall design, whether it's sleek and modern, rustic and vintage, or somewhere in between. Let’s break it down by style:

Modern Bathrooms

Modern bathrooms thrive on simplicity and clean lines. Here, frameless mirrors or mirrors with thin, minimalist frames often work best. Look for mirrors with geometric shapes, like rectangles, ovals, or even unique hexagonal and organic asymmetrical designs. Illuminated mirrors are both functional and chic. They make applying makeup or shaving easier, whilst casting a flattering glow.

Traditional Bathrooms

For traditional bathrooms, framed mirrors are often a must. Opt for ornate frames with intricate detailing in finishes like brass to bring an air of elegance. Round or oval mirrors are a popular choice for traditional bathrooms, offering softer lines that evoke a sense of timelessness. A vintage-inspired mirror with a decorative frame can become the focal point of the room. Don't be afraid to go bold!

Transitional Bathrooms

Transitional bathrooms combine elements from both traditional and contemporary design, making mirror selection a bit more flexible. In these spaces, you can pair a sleek, modern mirror with more classic fixtures or opt for a framed mirror with clean lines.

Industrial or Urban Bathrooms

For industrial-themed bathrooms, look for mirrors with features like black metal and chunky frames. Mirrors with shelves are perfect for capturing the essence of industrial design whilst arched or circular mirrors are an iconic choice that bring balance to the harsh, angular lines often found in this style.

2. Shape: How Mirror Shapes Influence Bathroom Design

Now that you've narrowed down the style, it's time to consider the mirror’s shape. This might seem like a purely aesthetic decision, but the shape of a mirror can dramatically influence the bathroom’s overall feel.

Rectangular Mirrors

Rectangular and square mirrors are classic and versatile. They are ideal for almost any bathroom style and will create a sense of structure and symmetry, which can help ground your design.
Best for: Modern, transitional, or industrial bathrooms.

Design tip: Place two rectangular mirrors side by side over a double vanity for a symmetrical and balanced look.

Round Mirrors

Round mirrors soften the look of the bathroom and add a sense of flow. They work especially well in spaces where the design feels rigid or linear and you want to introduce a touch of softness.
Best for: Modern and industrial spaces.

Design tip: A large round mirror above the vanity creates a strong focal point. Pair it with wall lights on either side to enhance the look.

Oval Mirrors

Oval mirrors are similar to round mirrors in their ability to soften a room’s design, but they’re slightly elongated, which can add height to the space. They bring a more traditional or vintage feel and look elegant in both small and large bathrooms.
Best for: Traditional or vintage bathrooms.

Design tip: For a classic look, hang an oval mirror vertically above the vanity. If you want something more unexpected, consider hanging it horizontally.

Irregular Shaped Mirrors

If you’re designing a bathroom with an artistic or avant-garde feel, consider going for irregular shapes like hexagons, organic forms, or arched shapes. These mirrors can act as functional artwork and bring a creative edge to the space.
Best for: Eclectic, modern, or bohemian bathrooms.

Design tip: An irregular-shaped mirror can stand alone as a statement piece. Keep the rest of the room’s décor simple to let the mirror shine.

3. Size: Striking the Right Balance in Scale

A common mistake in bathroom design is choosing a mirror that’s the wrong size for the space. If it’s too small, the mirror can look out of place, but if it’s too large, it can overwhelm the room.

Mirror Width

In general, the mirror should be slightly narrower than the vanity or sink. If you’re installing a mirror over a single vanity, aim for it to be about 70-80% of the width of the vanity. For double vanities, you can either choose two smaller mirrors or one large mirror that spans the width of the vanity.

Pro tip: When choosing a large mirror, be mindful of the bathroom’s layout. A mirror that’s too wide can interfere with lighting fixtures or shelving, so plan accordingly.

Mirror Height

The height of the mirror depends on the ceiling height and the placement of your light fixtures. The bottom edge of the mirror should sit 4-6 inches above the sink. Taller mirrors can give the illusion of higher ceilings, while a wider mirror can help open up the room horizontally.

Pro tip: When positioning a mirror, consider the height of the people who will be using it. The mirror should be hung at a height where most users can see themselves comfortably from head to chest.

4. Frame Material & Colour: How to Complement the Bathroom's Fixtures and Hardware

The frame of the mirror is another key detail that should harmonize with the bathroom’s overall design. When selecting a frame, consider the other finishes in the bathroom, such as your taps, shower brassware, accessories & other hardware.

Metal Frames

Metal frames in finishes like matt black, brushed brass or chrome are popular choices because they pair well with most bathroom hardware. A black metal frame, for example, adds a contemporary, industrial edge, a brass frame can warm up the space with a hint of glamour and a bronze frame will bring a touch of luxury.
Best for: Modern, industrial, or transitional bathrooms.

Frameless Mirrors

For a truly minimalist look, frameless mirrors are an excellent option. Without a frame, the mirror almost disappears into the wall, making it ideal for modern or small bathrooms where you want to keep things sleek and simple.
Best for: Modern, minimalist, or contemporary bathrooms.

Wooden Frames

Wooden frames bring warmth and texture to a bathroom, making them a great choice for rustic, vintage, or transitional styles. Look for natural wood tones or distressed finishes that complement the overall colour palette. Light wood frames can create a Scandinavian vibe, while darker woods offer a more traditional or rustic feel.
Best for: Rustic, farmhouse, or vintage bathrooms.

5. Lighting & Popular Features

Beyond the aesthetics of your mirror choice, it is important to consider the various practical options that are on offer as well.

Lighting

Good lighting can enhance the mirror’s functionality and the bathroom’s overall ambiance. Wall lights placed on either side of the mirror provide even, flattering light, while LED backlit mirrors are a great option for modern designs. They provide soft, diffused lighting that eliminates shadows, making them perfect for grooming and makeup application.

Demisters

We have all been in the frustrating position of not being able to use a mirror because it has steamed up whilst you shower or bath. A demister pad gently heats the back of the mirror to keep it steam free so you can go straight from the shower to seeing your reflection. Some mirrors come with this built in, but the majority of our mirrors can be ordered with an optional demister pad.

Shaver Sockets

Some mirrors come with shaver sockets included so you can charge shavers and toothbrushes from the mirror. Not all mirrors are available with this option (more ornate / design-lead mirrors don’t have suitable frames for the socket), in which case you can easily fit a shaver socket to the wall.

Final Thoughts

Choosing the right bathroom mirror is more than just an afterthought, it’s a crucial design decision that impacts both the functionality and style of the space. By considering the bathroom's overall aesthetic, the shape and size of the mirror, and the materials and finishes that complement the design, you can create a cohesive and beautiful look that will create the perfect finishing touch to your space.
