I wouldn't do skirtings . I'd do the floor tile for '1 tile' up the wall ( assume they are 200 x 200 or 300 x 300 -- cut them if 400 or 600 ) . Personally , I'd probably even do the 'silver' tiled areas in that 1 height darker tile too , as it would make the whole room look more 'level' , but thats up to you and your tiler .

Hi there. If the tile you have has character, you could pull a colour from some of that character, for example if the tile had a beige fleck through out you could use a similar beige tile in the bedroom, otherwise just choose something that compliments the tile well to create a soft transition. Then use the colour of the existing tile in the room somewhere, with your bed linen for example or bedside lamp. Feel free to share an image of the existing tile.

Used beveled subway tiles for whole bathroom without thinking about internal corners so the corner looked terrible then the silicon went on and it still looks terrible I guess apart from an aluminium strip or a marker to go across the silicon there aren’t many options

Hi. We have a small to medium sized bathroom. Just wondering do you think I should tile floor to ceiling with 60cmx60cm light grey tiles stacked or 30cmx60cm in brick layout
