Choose a bathroom mirror shape around the vanity, viewing area and style you want to create. Rectangles give a structured reflection, circles soften straight lines, ovals suit taller compositions and arches create a focal point. An irregular outline can add character. Shape alone does not determine lighting quality or make a small room feel larger.
Round: a softer focal point
A circle works well against rectangular tiles and straight vanity lines. Compare the diameter with the clear wall and furniture; remember that the useful reflection narrows near the top and bottom. Browse round LED mirrors to compare actual sizes.
80 cm round backlit mirror — £179. A broad curved reflection and rear glow for a vanity with enough wall width. Consider the room’s face lighting alongside the backlight.
Oval: height without a wide rectangular outline
An oval can give a taller reflection while softening the edges of a narrow wall. It is still important to measure its widest point and check the reflection for regular users. Compare oval LED mirrors rather than assuming every oval has the same proportions.
50 × 70 cm oval double-light mirror — £148. A curved option with front and rear lighting, dimming and anti-fog for a more compact vanity wall.
Irregular: a deliberate decorative accent
An organic edge gives the wall a less formal shape. Leave enough visual space around it so the outline can be appreciated; a busy shelf or competing feature may weaken the effect. Explore irregular mirrors for different silhouettes.
50 × 70 cm irregular LED mirror — £139. A flowing illuminated outline for a feature vanity. Test the overall dimensions and usable reflection before deciding from the shape alone.

Rectangle, square or arch?
A rectangular mirror provides a structured viewing area and can suit a single or wider vanity. A square mirror creates a balanced geometric composition. An arched mirror combines a straight base with a curved top, useful when you want a taller focal point.
These are styling choices, not rules that confine a shape to traditional or modern rooms. Repeat a finish already present in taps or lighting, or use the mirror as a deliberate contrast.
Choose the lighting separately
Round and oval shapes do not automatically diffuse light better across the face. Light direction, output, position and the surrounding room matter. Front lighting faces the viewing area; backlighting mainly washes the wall; double-light mirrors combine the effects.
For close detail in a dry dressing area, makeup mirrors with lights serve a different need. A wide bathroom wall mirror does not provide magnification simply because it has a large reflection.
Test the proportions before ordering
Mark the outline above the basin, then check it from the doorway and at the tap. For a double vanity, compare one continuous mirror with two separate mirrors; neither is automatically better. Include the existing lights, mounting clearance and any cabinet door swing.
