The Truth About Mitres
It’s no secret that we love mitres. Like, really LOVE them. Mitred edges or mitred finishes result in a minimal, seamless profile that allows your tile to take centre stage — without the distraction of a trim. Mitred joints create a sleek designer look that speaks of quality and luxury, perfect for bathroom remodelling, kitchen renovations, and other home improvement projects. Mitred edges are one of the finishing details that take a tiled area to the next level.

What is a Mitred Edge?
A mitred edge, also known as a mitred tile corner or mitred joint, is one of the options available to you when tiling external corners. A mitred tile is cut at a 45-degree angle along an edge, essentially removing the ‘biscuit’ or underside of the tile. Two mitred edge tiles are then butted against each other to form a neat finish at the corner so that only the face of each tile is visible.
A quality professional tiler can create a beautiful mitred tile edge, without chipping or damaging the edge of the tile, whether it's a ceramic tile installation, porcelain tile installation, or stone tile installation. That being said, stronger materials like porcelain and stone are generally easier to mitre and create a cleaner cut, compared to materials like ceramic tiles.

When to Choose Mitred Edges: Mitred edges are ideal for:
Modern and contemporary designs.
Minimalist styles.
Spaces where you want the tile to be the focal point.
Projects where a seamless, high-end finish is desired.
Z + S Tip • Opting for mitres in your home? Ensure the tiler does not grout where the two mitres join, as the grout tends to crack over time. Mitred joints should be siliconed, which allows for movement, protection and flexibility. Never assume that your tiler knows that you wish to silicone the mitred join. Always communicate this detail with your tiler so there is no confusion or room for error.

Mitred Edge Costs
So you love mitred joins and have decided they’re the best thing since sliced bread? We’d have to agree. Just be prepared to pay for the service, as mitres are an extra bathroom cost that most tilers will charge for. The extra cost is due to the labour required to cut each tile to form the mitre. Expect to pay approximately $45 - $75 per lineal metre for mitres, depending upon your tiler.

Alternatives to Mitred Edges
Are mitred edge tiles not in the budget? Or worried about chips in your mitred joints?
The alternative to mitred tile installation is tile trims. Tile trims are generally made of plastic or aluminum, and are more durable and chip-resistant than mitred edges. They come in a variety of materials, colors, shapes, and sizes to suit your specific design needs.
When using a tile trim, your tiler may automatically reach for a standard chrome finish trim. , however, there’s a range of alternative colours and finishes that may blend and work more seamlessly with your tile, so do your homework and communicate your finish. A white slimline trim may hardly be visible when used against white tiles.
Z + S Tip • Never leave the trim colour selection up to your tiler as they might automatically reach for a standard chrome finish trim, which may not be the best option for your colour scheme. There’s a range of tile trim colours, profiles and finish options, including black, white, brass, brushed and matte. Consider which will suit your bathroom design best and work most seamlessly with your tile.

Mitred Tile Tips for Home Renovators:
Do not assume your tiler will mitre the tile edges for your tile installation.
Some tilers do not mitre tiles due to the time and skill involved and may try to convince you to use a tile trim instead. Decide what’s right for you and your home improvement project. You may need to find another tiler or be steadfast on your preferred tile finish. A tiler who is experienced with mitre joint tiling will be proud to show you images of their past work and will support you in achieving the result you want for your home.
Communicate your preference for tile edge finishes clearly when obtaining a tiling quote to avoid cost variations, and before your tiler begins any tiling work — whether it’s for mitred tile corners or a tile trim.
Research and choose the right trim for your tiles if you decide against mitres.
Ensure your tiler uses silicone instead of grout for mitred joins.
Look for inspiration from examples of mitred edges in different settings.
Consider tile-cutting techniques and tools to achieve mitres accurately.

So there you have it. Mitres, in a nutshell. As much as we love them, there’s definitely a time and place when a tile trim is the best alternative.
Tiling a rental property? Tile trims might not be such a bad idea. Have 7 kids and 4 dogs? Trim everything — they’re more bulletproof than tiles with a mitred edge detail.
But jokes aside, there are mitred edge pros and cons, and having a clear picture of mitred tile alternatives should make it easier to make an informed choice for your home improvement or bathroom remodelling project.
