How To Tile Inside Corner- A Step-by-step Guide

The process of tiling an inside corner can be summarized into five steps:

  1. Layout the tile
  2. Score and snap the tile
  3. Apply thin-set
  4. Install the tiles
  5. Grout and clean up

Layout the tile

The first step of tiling an inside corner is to lay out the tile. Layout the tiles according to your design plan. If you are doing a diagonal wall, you will need to use two different plans – one for each direction.

And then meet them at a point. When laying out tiles: Check for squareness. Ensure that the tiles are level from side to side and front to back. Notes down the layout plan, so that you will not forget where each tile needs to be placed.

Score and snap the tile

Once you have laid out your design plan, it is time to score and snap the tiles. Tiles are made to be durable, but they are not indestructible. If you want to fit the tile in an awkward corner or curve, it may require that you score and snap the tiles around these shapes. The method for scoring and snapping is as follows:

  • Use your tape measure to find the center point of the wall (center from left to right).
  • Then, use a pencil and your tape measure to mark the center point on the back of each tile.
  • Use a straight edge – such as a long, level – and draw a line from this center point diagonally across the tiles. Make sure that you keep it straight! *
  • Score the tile by pressing firmly down on the straight edge.
  • Use your tape measure to make sure that you are cutting at 90 degrees.
  • Apply pressure, using diagonal cuts to score the tiles between each notch.
  • Once you have scored enough lines in this manner, apply pressure with your thumbs and snap the tiles along these lines.

Apply thin-set

Before you can start installing your tiles, make sure that you apply the right amount of thin-set. You need to take into account the size and weight of the tile and where it is going.

For example, tiles in heavy traffic areas require a lot more adhesive than those which are located further back. Use a ratio of 2 pounds of adhesive for every square foot that you are tiling. If the tiles are very heavy, such as large tiles made from slate or marble, then increase this amount to 3 pounds per square foot.

Once you have your proportionate amount of thin-set, it is time to start applying it. Your goal here is to ensure that the adhesive covers the entire back of the tile. You can do this by dragging a trowel across this area, or you can spread it out with your fingers. The most important thing is that all of the tiles are covered in equal amounts!

Install the tiles

The next step is to begin installing the tiles. You will probably find it easier to work from the center out. If you are installing a diagonal wall, then install half of the tiles in each direction first and then meet them at a point.

  • Use a level or tile square tool to ensure that your tiles are level from side to side and front to back.
  • Use tile spacers to create even gaps between each tile.

Grout and clean up

The final step of tiling an inside corner is to grout the tiles. You can learn how to use a grout bag here. Make sure that every single gap is filled with thin-set, so that there are no air pockets.

Allow this glue time to dry – you will need to wait at least 24 hours before you can begin to use the tiles. Once the grout is dry, it is time for cleaning up. Use a sponge and clean water to wipe away excess thin-set from around the tiles and clean off your tools.

Make sure that everything is put away properly – including any leftover adhesive – so that it is ready to be used again the next time you do tile.

14 Tips For Making Your Tiling Look Perfect:

When tiling an inside corner, it is important to make sure your tiles are level and that the edges of the tiles are straight. If your tiles are not level or straight, your tiling will look uneven and sloppy.

Here are a few tips for making your tiling look perfect:

  1. Use a spirit level to check that your tiles are level.
  2. Use a straight edge to check that the edges of your tiles are straight.
  3. Cut tiles as needed to make sure the edges are straight and the corners are square.
  4. To tile an inside corner, start by deciding what pattern you will use. Most people like the look of a staggered brick effect when tiling an inside corner.
  5. Enlarge the pattern to suit your wall – don’t just copy it exactly!
  6. Work out how many tiles you need for each row and draw a level line across the wall, marking the top tile.
  7. Ensure your tiles are straight along this line and then start tiling from the corner furthest away from the door or window.
  8. Insert spacers between each course of tiles to keep them level/straight until you get to a corner.
  9. Cut extra tiles as needed for corners, remembering to keep spacer widths between courses.
  10. Remove spacers as you get to them/them – don’t just leave them in!
  11. Once you reach the corner, cut a tile diagonally and attach it to the adjoining wall with adhesive caulk.
  12. Repeat for other inside corners.
  13. You can then choose whether you want to just grout with a clear silicone sealant or whether you want to also apply adhesive caulk between tiles and then grout.
  14. Remember: always use full-strength adhesive caul on the wall side of inside corners, so this is where you will be applying it!


Now that you know how to tile inside a corner, it is time for you to get started on your next project! Remember to take into account the size and weight of the tiles and where they will be installed.

Make sure that you apply thin-set in equal amounts, using a trowel or your fingers. Install the tiles from the center out and use a level or tile square tool to ensure that they are straight.

Finally, grout the tiles and clean up afterward. We hope you have found this article helpful
