Arch or rectangle: choosing a mirror shape
The heart of our full length range is two shapes: the Sienna arch and the Cecelia rectangle. Same glass, same slim frame, same 2-year warranty. The only real decision is the silhouette, and it changes more than you'd think.
What the arch does
The arch is the softer, more classical line. It echoes doorways and windows, which is why an arched mirror can make a plain rental wall look architectural. It reads warm and a little romantic, and it forgives rooms full of mixed furniture because the curve doesn't compete with anything.
The Sienna arch comes in three sizes: 1700 x 610 at $315 and 1800 x 850 at $560, both in stock now, and the oversized 2000 x 1100 at $760 on pre-order for August 2026. Finishes vary by size across Matte Black, Antique Copper, Brushed Gold and White Satin, so check the product page for what's available in yours.
What the rectangle does
The rectangle is the modern, architectural choice. Clean verticals, softly rounded corners so it never goes harsh, and a shape that lines up beautifully with shelving, door frames and panelling. If your room runs to straight lines and considered angles, the rectangle belongs in it.
The Cecelia rectangle is 1800 x 850 at $580, in stock in all four finishes. Its smaller sibling, the Cecelia 1700 x 610 at $330, is on pre-order for August 2026.
How to choose
Look at the lines your room already has. Arched doorways, curved furniture, soft textiles: the arch will feel like it grew there. Square rooms, straight joinery, a more graphic style: the rectangle matches the rhythm. Both approaches work; one harmonises, the other can deliberately contrast. A single arch in a very linear room becomes the focal point precisely because it's the only curve.
If you're still split, think about the top of the mirror. The arch draws the eye up and adds visual height, which small rooms love. The rectangle frames you more like a portrait and feels slightly more formal, which suits a considered hallway or a dressing room.
And if neither feels like you, the full length range also has two sculpted outliers: the wave-edged Felicia and the curved Allira, both on pre-order for August 2026 in the full length collection.
The practical bits
Both shapes lean or hang, both come with fixings, and both need anchoring if they lean. Both are 25mm deep with the same slim frame profile. Delivery is the same too: $100 flat, free over $800, brought to your door by our own team across Melbourne, and Brisbane to Coolangatta for the Sienna range.
