Undulation and Bowing in Handmade Tiles

One of the challenges often encountered with handmade tiles is undulation, also known as bowing, where the tiles have a slight curve or warp. This occurs due to the natural drying process during production as well as the plastic nature of clayand can vary from tile to tile.The bowing
will always be within acceptable parameters and will not compromise the integrity of the tile. For this reason we always recommend you hire an experienced tiler with an understanding of handmade tiles.

A sign of Authenticity:

While bowing might be seen as a flaw in machine-made tiles, it adds to the authenticity of Two & A Half Dimensions handmade tiles. These subtle imperfections remind us of the human touch that goes into their creation and contribute to their unique character.

Installation Techniques:

Irregularities across the surface are common, and tiles may not always be perfectly flat. However they will always be able to adhere to a surface securely when done by a professional who will set them on adhesive in order to give them a firm bed.You may need to slightly build up the adhesive to accommodate for differences. Once again, rotating and laying tiles out in advance will ensure that your measurements are correct and adjusted according to the variations in size and appearance that come with handmade tiles.

Grouting Handmade Tiles

Grouting is the final step in the installation of Two & A Half Dimensions handcrafted tiles, and it’s a critical stage where variations in colour, shape, size, surface undulation, and bowing are integrated into the overall design.

Choosing Grout:

Selecting the right grout colour is essential when working with Two & A Half Dimensions handcrafted tiles. Grout can either blend in with the tiles, creating a harmonious look, or contrast with them, highlighting their variations and enhancing their unique beauty.

Grouting Techniques:

Our tiles are often laid with minimal grouting to enhance the visual effect. We recommend that corners of tiles touch and grouting be left to fill the irregular spaces between.


Always involve your tiler in these conversations as they may have specific techniques they feel comfortable using. Please ensure that you consider the 3D nature of the tiles and how that might impact the final appearance. Grout sealant is recommended after installation.

We recommend Mapei wide joint grout, as they offer a wide selection of colours. Excessive grout must be cleaned off tiles with a wet sponge immediately after installation.
