Look at any tiled wall or counter and your eye, even an untrained one, goes to the same place: the edge. Where two tiled surfaces meet — an external corner, the lip of a counter, the top of a half-wall — is where the whole job confesses how much care went into it. A clean edge reads as expensive; a clumsy one cheapens everything around it. Here are the ways that edge gets finished, from the budget option to the one that quietly says the tiler knew what they were doing.

The options, cheapest to finest

1. PVC trim — the budget default

A plastic strip, usually with a rounded face, that caps the tile edge. It's the cheapest finish and the fastest to fit, which is why it's everywhere in value jobs. The downsides show quickly: plastic looks like plastic, the white yellows over the years, it scratches and dents, and the rounded profile reads as dated. It does one useful thing — protect the fragile tile edge — but it never looks premium.

2. Metal trim — the reliable upgrade

The same idea executed in aluminium or stainless steel (the category most people know by the brand “Schluter”). A slim metal profile caps the edge in a straight, crisp line, comes in finishes from matte black to brushed steel to match your fittings, and shrugs off knocks far better than plastic. It's the sensible middle ground — clean, durable, modern, and not expensive. For most homes, a good metal trim is the smart default.

3. Bullnose and pencil edges — the finished tile

Some tile ranges include matching edge pieces — a bullnose (a tile with one rounded, glazed edge) or a slim pencil-liner in the same material. Because the edge is the same fired surface as the tile, there's no foreign strip at all; it reads as one continuous material. Lovely when the range offers it — but many modern tiles, especially large-format porcelain, simply don't, which leads to the top option.

4. The mitred edge — the craftsman's finish

Here the two tiles meeting at a corner are each ground to a 45° bevel along their backs and joined so their faces form a single, seamless return — like a perfectly mitred picture frame. No trim, no strip, no contrasting line: just the tile itself wrapping the corner, so a stone-look porcelain genuinely looks like a solid slab folded around the edge.

It's the most expensive option, and for good reason — slow, skilled handwork. The 45° cut leaves a delicate, sharp arris that chips if rushed or knocked, so it demands a steady hand and good tiles. Done right, it's the edge that makes people assume you used solid stone. Done badly, the joint gapes or the corner crumbles — which is exactly why it's the truest test of a tiler.

Anyone can lay a tile in the middle of a wall. The corner is where you find out who you hired.

Where each one belongs

  • PVC trim: tight budgets, rentals, hidden service areas. Honest, cheap, temporary-feeling.
  • Metal trim: the all-rounder — kitchens, bathrooms, most homes. Crisp and durable without the premium price.
  • Bullnose / pencil: when your chosen range includes a matching piece and you want a soft, finished tile edge.
  • Mitred 45°: feature walls, kitchen islands, full-height stone-look surfaces — anywhere the edge is on show and you want it to disappear.

The bottom line

The edge is small, constant and quietly decisive. You don't need a mitred corner everywhere — but you should choose the edge on purpose, not let it default to a yellowing plastic strip. Spend the craft where the eye lands, and the whole room reads as a finer job than it cost.
