Scale is not guessed
Because the room is measured, a 600 mm tile reads as a 600 mm tile rather than whatever size looks good in the frame.
Materials
Real materials, on your real surfaces.
Put oak, porcelain, quartz or terrazzo onto the floor and worktops in your photograph, at the right scale for the room they are in.
Direction and grout
Plank direction, herringbone, grout colour and joint width, all of which change a room more than the material does.
Bring your own
Upload a photograph of a sample from a supplier and apply that instead of a preset.
