We used the same ones. Attached the pricing. Our builder got them for slightly cheaper than the sale price.

Have you already sourced your tiles? I would expect most tile stores could help you find the edging tiles which I think are typically termed 'pencil' tiles for the style you have shown. We used bevelled subway tiles in our DIY ensuite. In hindsight we would have aimed to finish the brick pattern with 1/3 and 2/3 sized tiles (like in your pic 1) rather than full and 1/2 (pic2 and 3) to give a more even edge thickness/profile... Might not suit and we didn't use capping tile (I lost that arguement!) so it is probably more obvious in our bathroom, but just something you might like to consider.

Large format tiles, such as your 700 x 400 choice look great in large rooms. However with smaller spaces, such as bathrooms in a unit then you really have to plan carefully with your tiler the relationship of the floor waste, the slope, and the grout lines. If your tiler starts setting out the tiles from your entrance hall you may find that there is only one off-centre grout line down the middle of your bathroom , or an awkward transition to make it work with the existing floor waste. A smaller square tile, such as 400 x 400 will be easier to work with, easier to set out, easier to work with slopes, and the position of the grout lines will be less crucial.
