What Is Tile Mitring?
Tile mitring is a finishing technique where two tile edges are cut to approximately 45° so they meet to form a neat external corner without using a separate tile trim.
Why Are Tiles Mitred?
The primary purpose of mitring is to create a clean, seamless corner without a visible trim. The pattern, colour and texture appear to wrap around the corner, producing a refined architectural finish.
How Is Tile Mitring Done?
The edge of each tile is cut to approximately 45 degrees using specialist equipment before two tiles are joined to form a precise 90-degree corner.
What Is Tile Trim?
Tile trim is a purpose-made profile fitted to exposed tile edges to provide protection and a neat decorative finish. Trims are available in aluminium, stainless steel, PVC, brass and ceramic.

"Any tiler can produce perfect mitres."
Accurate mitring requires specialist equipment and experience.
Frequently Asked Questions
Which looks better?
It depends on the design. Mitred corners create a minimalist look while trims provide a defined protective edge.
Can all tiles be mitred?
Most porcelain and ceramic tiles can, although fragile or heavily textured tiles may be less suitable.
Are mitred corners more expensive?
Usually yes, because they require extra cutting and labour.
Do mitred corners chip easily?
They are generally more vulnerable to impact than protected trim edges.
Conclusion
Tile mitring and tile trims are both recognised methods of finishing exposed tile edges. The right choice depends on the desired appearance, budget and durability requirements.
