Corner work comes down to two decisions: which profile finishes the edge, and which cutter holds a clean miter. These are the parts a pro orders for it.
- EMAC Novocanto Aluminium, the curved edge profile for outside corners. It protects and finishes vertical tile edges, runs in 7 ft 11 in. lengths at 3/8 in. and 1/2 in. heights, and has a Zamak complementary piece that joins two runs at a right angle.
- EMAC Novoescocia 4 Aluminum, the cove profile for inside corners and wall to floor joints. Also 7 ft 11 in. lengths, with internal angle, external angle and cover pieces, installed on finished tile with a silicone adhesive.
- Or browse the full metal trims and transitions range, the RUBI manual tile cutters, and the tile spacers that hold the expansion gap described in step 3B.

How to tile a corner
Mastering the technique of tiling into a corner sets true professionals apart. Poorly finished corners lead to leaks, unappealing visuals and costly repairs. Take into account:
1. Must-have Tools for tiling into a corner
Part of the quality of the job depends on your gear. Make sure your toolbox includes:
-
Specialized adhesives: choose the right for the substrate and environment (moisture, traffic, temperature): using the proper mortar keeps tiles secure and leak-free.
-
Spatulas and notched trowels: crucial for spreading adhesive with the correct texture
-
Tiling tools like a manual tile cutter or a wet tile saw: precision in cuts is vital, especially for angled and corner pieces.
-
Corner trims or profiles: perfect for protecting and beautifying edges on outer corners.
-
Rubber hammer and sponge: adjust tiles without damage and keep surfaces clean
-
Spacers and laser level: maintain joint uniformity and ensure your installation stays straight.
2. Accurate Measurement
There are several methods you can use to measure tiles before cutting them. One way is to place the tile you intend to cut on top of a full tile. Next, position another tile against the wall so that it overlaps with the first one. Using a carpenterโs pencil, mark on the tile the section that extends beyond the overlap, as this is the part that needs to be cut. When applying this technique, make sure to trim a little additional material from the tile to allow room for the grout joint (2-3mm extra).
Another method is to use a tape measure to obtain the correct dimensions. Measure carefully from the top corner of the space you are tiling down to the bottom corner, and then transfer those exact measurements onto the surface of your tile by marking them with a pencil. When marking, itโs a good idea to double-check your numbers to avoid mistakes that could waste materials.
Once your tile is marked, there are several tools available for making the actual cut. Manual tile cutters are commonly used for straight, simple cuts on ceramic tiles. A wet tile saw is specially recommended for precise cuts in thicker or more delicate tiles, such as porcelain or marble, since the water helps reduce dust and prevents the tile from overheating and breaking.

3. Tiling into a Corner with Trim or just Tile
Explore trim or tile methods:
A. Corner Trim method
This approach guarantees durable resort, especially on crooked walls. Secure it with adhesive and make sure itโs level. Once dry, the trim locks in place, protecting corners from impact and moisture.
Benefits of this method:
-
Shields tile edges from damage
-
Clean, professional finish
-
Disguises minor misalignments
B. Tile-Only Method
You donโt necessarily need plastic trim to finish corners when tiling.
For inside corners (angles under 180ยบ), start by tiling one of the walls first. Spread the adhesive with a notched trowel and press the tiles into place. Be sure to leave a narrow gap between the tiles and the actual corner, since tiles need room to expand slightly. Tile spacers are useful to keep this spacing uniform. Once the first wall is done, continue with the tiles on the adjoining wall.
For outside corners (angles greater than 180ยบ), add an extra step: the tiles at the edge should be cut at an angle (miter cut), to allow both edges to meet cleanly along the corner, creating a sharp, seamless look.

4. How to fill corner joints: grout or caulk?
Over the years, using grout in corners has led to cracks and separation. The recommended solution is caulk (silicone, latex, or acrylic). Fill gaps between tiles and the corner to prevent leaks and movements.
Advantages:
-
Flexible for temperature and moisture changes
-
Total waterproofing
-
Easy maintenance
5. Grout lines, the final touch
When grouting, spread the grout both horizontally and vertically. Wipe away excess with a damp sponge before it dries. Then buff with a dry cloth for a shiny, professional finish. If you want a professional look, try professional joint sealers and polishers to avoid stains and keep your installation looking fresh.
Frequently asked questions about tiling a corner
Do you need corner trim to tile a corner?
No. Both methods in step 3 work. A corner trim profile shields the tile edge, gives a clean finish and disguises minor misalignment, which makes it the safer choice on crooked walls. The tile only method skips the profile: tile one wall first, leave a narrow gap at the corner so the tiles can expand, and on outside corners cut the edge tiles at an angle so both faces meet cleanly.
Should corner joints be grouted or caulked?
Caulk. As step 4 explains, grout used in a corner has led to cracks and separation over the years. A silicone, latex or acrylic caulk stays flexible through temperature and moisture changes, seals the gap against leaks and movement, and is easier to maintain.
How do you cut tile for an outside corner?
Mark the cut using the overlap method in step 2, trimming 2 to 3 mm extra to leave room for the grout joint, then cut the edge tiles at an angle (a miter cut) so both edges meet along the corner. Use a wet tile saw rather than a manual cutter for thicker or more delicate tile such as porcelain or marble, since the water reduces dust and stops the tile overheating.
