Moisture-safe materials
Not every wall mirror belongs in a bathroom. Cheap MDF frames swell and delaminate when they meet steam. Raw iron rusts. The two materials that hold up long-term in US bathrooms are:
- Powder-coated iron — the coating seals the metal completely. All Salkala Decor arched and window pane mirrors use this.
- Stainless steel — heavier and more expensive, but essentially rust-proof.
Sizing to vanity
The mirror should be within 2–4 inches of the width of the vanity below it:
- 30″ vanity: 26–28″ wide mirror
- 36″ vanity: 32–34″ wide mirror
- 48″ vanity: 44–48″ wide mirror
- Double vanity (60–72″): two matching arched mirrors, one over each basin
Placement height
Position the bottom of the mirror 5–10 inches above the top of the faucet — not the countertop. This gives clearance for a soap dispenser or tumbler and puts the reflection at a natural face-level.
5 styling ideas
- Arched over rectangular. An arched mirror softens the boxy geometry of most vanities.
- Add wall sconces at temple-height on either side — best light for makeup or shaving.
- Skip the top row of tile if your walls are half-tiled — mount the mirror slightly into the tile-free zone for a cleaner look.
- Warm brown iron pairs with brass fixtures; matte black pairs with chrome or matte black fixtures.
- Small powder rooms can take one oversized mirror — a 32×20 in a tiny half-bath actually looks intentional, not crowded.
