“These tiles are advertised for floor and wall however be mindful that grout lines will not align if the tiles are laid in opposite orientation as a result of the tiles being 600x300.
Manufacturers generally reduce the 300 dimension by 1 or 2mm to allow for grouting and still align with the 600 length dimension however these do not.
Would suggest this probably needs to be highlighted on the website description”
Each tile is subject to certain tolerance in line with British tiling regulations. This should not affect the overall installation. If you would like to discuss this with our customer service team please contact us.
