With tile that size you will probably have to do no more than a 33% offset, so you might want to redraw it that way. Also consider a stacked pattern.

why do people use 33% offset, that seems weird to me. I'll try to draw it in however.

Update: the offset seems like it might be awkward in that toilet room

Large format tile set at greater than a 33% offset pattern is very very prone to lippage.
