Chris it all depends..... it depends how the tiles fit at the edges of the floor - as you can see, on Master of None's (apart from CAD - he's good at that) bathroom, the size of tile does not lend itself to a pleasing layout. Diamond layout hides this issue and makes the floor area look bigger becasue it draws your eyes in all directions.without wanting to hijack this thread...
I am tiling a (virtually) square room, with a corner shower. approx 4sqm
gcol - would you recommend tiling this is a diamond pattern? It's obviously more difficult, what are the advantages?
Sure it's harder to lay, but in certain circumstances, it makes a huge difference.
