How this size fits
This size benefits from careful checks around lighting, faucets and ceiling clearance because its larger curve occupies more of the wall.
Made to the stated size
A custom 30 × 40 mirror
Centennial Glass can fabricate a frameless mirror to these exact dimensions, finish the exposed edges, add safety backing where appropriate, and arrange professional installation. Framed oval mirrors are available as completed designs in the ready-made collection. Practical material, access and mounting requirements are confirmed before fabrication.
Orientation and proportion
Most vanity installations use the 40-inch dimension vertically. A horizontal installation creates a wider decorative composition where mounting permits.
Mirror size or finished size?
For custom fabrication, 30″ wide × 40″ high describes the frameless glass itself. A ready-made framed product is listed by its completed product dimensions, which may include the frame.
Measure around the installation
Account for the vanity, faucet, backsplash, lighting, switches, outlets, trim and available mounting surface—not only the open wall width.
Two ways to choose
Custom frameless or ready-made framed
Choose exact frameless fabrication when the dimensions lead the project, or browse the ready-made collection for a factory-framed oval mirror with a completed profile and finish.
