These tiles are amongst the least expensive 300 x 600 tiles we have found. However the price does not indicate the quality - the tiles are excellent, relatively thin for their size at around 8mm, but they are strong and are really easy to work with and cut/drill/core etc for use in the most complex bathroom designs. As we live in a hard water area the semi-matt surface finish and stippled grey pattern is ideal for not showing water marks.
We have used these on several properties we have refurbished now and they have not failed to please in any installation. Highly recommended.
