How to Finish Tile Edges
20/01/2026
Finishing exposed tile edges correctly is one of the simplest ways to transform a tiling project from good to professional. Whether you’re a seasonal tiler or attempting your first tiling project, knowing how to make exposed tiles look finished can deliver more durable, polished results. This article guides you through finishing tile edges and the different types of tile trims used to do so.
Exposed Tile Edges Vs Trimmed Tile Edges
Exposed tile edges can enhance a room's aesthetic and design, and, as long as the tiles are installed correctly, they can be an effective finish. However, without a ‘cap’, exposed tile edges are vulnerable to cracking, discolouration, structural movement, and water seeping behind them. By adding a tile trim to your tile edges, you not only create a smooth, neat line that frames your tiles, but you also protect the tiles from dust or water getting trapped, as well as damage to the tiles themselves.
What is Tile Trim? Basics You Need to Know
Tile trim or tile edging is a strip of material that fits snugly along the exposed edge of tiles. Tile trims come in a range of styles, materials, sizes, and colours to complement your décor and preferences. They help give your tiled wall a finished look while framing and protecting your tiled surface.
Common Tile Trim Profiles
Straight Edge Tile Trim – For clean, sharp lines and a traditional finish. This also works well with thin, delicate tiles.
Square Edge Tile Trim – A 90-degree angle trim that suits more modern styles for a feature yet functional trim.
Decorative Trim – Colours such as copper or brushed auburn add an accent or feature border to your tiles.
Metal Finishes – Chrome, brushed, gold, or stainless add a premium aesthetic, but also work well in high-traffic areas.
Plastic/PVC Trim – A versatile, budget-friendly option that’s easy to cut and install.
Corner Trims – Ideal for capping and smoothing the corners where tiles or tile-and-surface edges meet.

How To Make Exposed Tile Edges Look Finished
Before you begin, pick up all your tile trim and edging tools from Premium Tile Trim, and follow our step-by-step guide:
Step 1: Measure & Select the Right Trim
Using a tape measure, measure the length and thickness of the tile edge. You want the tile trim to be 1-1.5mm thicker than the tile itself, so it fits neatly behind the tile.
Step 2: Prepare the Edge
Ensure the exposed tile edge is clean, dry, and free from dust or grout. This will help the trim adhesive bond securely and evenly.
Step 3: Cut the Tile Trim to Size
We recommend using a mitre saw, such as the Proxxon KGS 80 Chop & Mitre Saw or a hacksaw with a fine blade to cut metal tile trims. A fine-toothed saw is suitable for Plastic/PVC trim. Measure the trim to the correct length and make a straight, clean cut.
Step 4: Apply Tile Adhesive
Select a tile adhesive compatible with your trim material, and apply a thin layer to the back leg (the bit that goes behind the tile) of the trim.
Step 5: Install Your Trim
Position the trim so it hugs your tile edge. Then press the trim firmly into place, pressing down to ensure a tight adhesive bond and a flush finish.
Step 6: Clean Up
Once in place, wipe away any excess adhesive before it sets, and leave for the recommended curing time.

Different Ways to Add Tile Edging
If you’re looking to elevate your tiling project beyond basic edging, here are some creative ways to install tile trim:
Frame Feature Walls: Consider contrasting trims, such as gold or black, to frame your tile wall. These are a popular look for kitchen splashbacks or bathroom niches.
Create a Border: Use straight tile trim around the perimeter of tiled areas for a picture-frame effect. This is especially effective with patterned tiles.
Mix Up Materials: Pair metal trims with natural stone or porcelain tiles to combine modern and classic styles. This works well for contemporary designs.
Colour-Match Tiles & Trim – For a flawless look and for the trim to disappear, match your trim to your tiles and/or tile grout for a sleek, professional finish.

Choosing The Right Tile Trim For Your Tiles
There are a few things to consider when selecting the best type of tile trim to finish your tiling project:
Size – Ensure the trim thickness matches your tile thickness. We recommend going 1-1.5mm thicker than the tile thickness to account for variations in tile adhesive and substrate. Explore our range of tile trim from 4mm to 30mm to find the right fit.
Colour – Whether you want your tile trim to stand out or blend in, we offer a range of colours, including silver, beige, rose, and gold, to suit your design. Choose a colour that complements your tiles and tile grout for a cohesive look.
Material – Choose a material that suits your style and the room's purpose. Bathroom tile trim is better suited to water-resistant materials like PVC & coated metal, whereas external tile trim may benefit more from hardwearing metal tile trim.
Shape – This will be the top of the tile trim, which is visible. Decide which trim shape and style you prefer: rounded tile trim for a smooth edge, straight edge tile trim for a crisp line, or square edge tile trim for a more modern look.
