Elevation (indicative, mm)
We assume a ~850 mm counter top and a backsplash to ~1000 mm. The mirror bottom sits at ~1050 mm so it clears the tap and splash, with its centre near eye level. Keep the top edge ~200 mm below the ceiling.

Estimates are indicative and assume standard Indian vanity ergonomics. Mirror mount height, tap and splash zones, and light positions vary with the tallest user, the basin and tap model and any wall storage — confirm the finished sizes and switch/point positions on site before ordering the mirror or cutting the electricals.
Frequently asked questions
- What size mirror should I get for my bathroom vanity?
- As a rule of thumb, keep the mirror a touch narrower than the vanity so it sits inside the counter — this tool suggests roughly 40 to 100 mm less than your basin width, and a height around 700 to 1000 mm. For a wide or double-basin vanity you can either run one long mirror or fit two mirrors, one over each basin. Treat the numbers as indicative and confirm on site.
- How high should a bathroom mirror be mounted from the floor?
- The calculator sets the mirror bottom edge at about 1050 mm from the finished floor so it clears a typical 850 mm counter and the tap and splash zone, putting the mirror centre near eye level. Keep the top edge roughly 200 mm below the ceiling. Adjust for the tallest user, your basin and tap model, and any wall storage before drilling.
- How much light do I need around a vanity mirror?
- For good, shadow-free face lighting this tool sizes about 1400 lumens per 600 mm of vanity, with a sensible floor of around 1200 lumens. Aim for 3000 to 4000K colour temperature and CRI 90 or higher for true skin tones. Two side sconces at eye level suit narrow vanities; a top light bar works better for wide or double basins. A backlit LED mirror adds even light and cuts the extra fixture load.
