Choosing the right bathroom mirror might seem like a small design detail, but it can drastically affect how your space looks, feels, and functions. Whether you’re remodelling a compact HDB flat or renovating a spacious condo in Singapore, finding the correct mirror size for your vanity is essential.
At Shower Screen Singapore, we specialize in making bathrooms functional and visually balanced. Our Bathroom Mirror Size Calculator is designed to help you find the ideal mirror size based on your vanity, ceiling height, and room layout. In this guide, we walk you through everything you need to know about sizing your bathroom mirror correctly, using both aesthetic and functional principles grounded in industry expertise.
Why Choosing the Right Bathroom Mirror Size Matters
Bathroom mirrors do more than just reflect your face; they reflect your entire design sensibility. The right mirror enhances your grooming routines, adds brightness by bouncing light around, and visually expands smaller bathrooms. In compact homes like Singapore’s HDB flats, a well-sized mirror can make a cramped bathroom feel significantly larger.
From a functional standpoint, the mirror needs to match your eye level and sink height, ensuring daily routines like shaving, skincare, or brushing teeth are convenient. It also needs to blend with the bathroom’s layout; too small, and it feels underwhelming; too large, and it overpowers your vanity or crowds lighting fixtures. That’s why it’s important to approach mirror sizing with both aesthetic balance and practicality in mind.
When you size your mirror properly, it also complements your shower screen, vanity, tiles, and lighting, creating a cohesive, spa-like atmosphere. At Shower Screen Singapore, we believe in optimizing every square inch of your bathroom, starting with the mirror.
Expert-Backed Bathroom Mirror Sizing Rules
Most design experts agree: a bathroom mirror should be approximately 70% to 90% of the vanity width. This provides symmetry while leaving a bit of breathing room on either side. For example, if your vanity is 90 cm wide, an ideal mirror width would be between 63 cm and 81 cm.
But it’s not just about width. The mirror’s height should reflect your ceiling height, wall tiles, faucet placement, and whether you have lights installed above it. In most Singaporean homes, ceiling heights range from 2.4 to 2.8 meters. This means a mirror height of 75 to 100 cm usually works well without overpowering the space.
Don’t forget practical details. The mirror should be mounted at a height that aligns with the average eye level of users, typically around 150 cm from the floor. At Shower Screen Singapore, we recommend leaving 10–15 cm between the bottom of the mirror and your sink to prevent splash stains, while ensuring ergonomic comfort.

Pro Tips for Choosing the Perfect Bathroom Mirror
Once you have your mirror size calculated, the next step is choosing the right style. At Shower Screen Singapore, we’ve seen thousands of bathroom configurations, and these tips consistently help homeowners make better choices:
- Shape matters: Round mirrors soften harsh corners and suit minimalist spaces. Rectangular mirrors maximize vertical visibility and suit modern, structured designs.
- Framed vs. Frameless: A framed mirror makes a bold statement and suits traditional or vintage-style bathrooms. Frameless mirrors offer a sleek, seamless look, perfect for compact condos or minimalist HDBs.
- Alignment is key: Make sure your mirror aligns with your shower screen, tiles, and fixtures. Misalignment can throw off the entire bathroom aesthetic.
- Avoid cluttered lighting: Don’t crowd your mirror with bulky light fixtures. Instead, place soft LED lights above or behind the mirror to create a warm, functional glow.
Your mirror should enhance, not compete with, other bathroom features like your shower screen, vanity, and wall tiles. Always consider the full visual picture.

Frequently Asked Questions
For a 36-inch (91 cm) vanity, the ideal mirror width would be 24 to 32 inches (60 to 80 cm). This leaves a few centimetres on either side for visual balance. Consider a mirror that’s also at least 30 inches (76 cm) tall to maintain vertical presence and accommodate lighting.
Not necessarily. A 24-inch mirror can work for a 30-inch vanity if the mirror is tall and well-centred. However, a 26–27 inch mirror might offer better proportion without overwhelming the spa
For double vanities, you can choose either:
- Two separate mirrors (each 70–80% of each sink’s width), or
- One long mirror that spans 70–90% of the total vanity length
Spacing is key; ensure each user has enough central alignment with their sink. For vanities longer than 120 cm, split mirrors often look better.
Absolutely. A round mirror can soften harsh lines and create a modern look. Just ensure it’s at least 70% the width of your vanity, and that it doesn’t look lost on the wall. Pair it with clean lighting and minimal accessories for the best effect.
If your sink is centered in the vanity, then the mirror should be centered over both. But if your sink is off to one side (as with some wall-mounted basins), align the mirror with the sink for functional use. Visual symmetry should always support practical use.
