I am ordering limestone look porcelain tiles. They are available as random mix packs of 5 sizes from 33cm x 33cm to 1m x 50cm or I could just have large 1m x 50cm or any other. Large would give less grout lines to keep clean but I quite like the look of "random". It is for an 8m long kitchen but needs to be able to continue through doorway into utility. Any thoughts as I have totally overthought it.
