in the bathroom, the black and white gray color matching is used to create a modern and simple style. The black and white tiles on the wall are matched with the gray floor tiles, which is simple and atmospheric. The white bathtub and washbasin are matched with the black faucet, which is both stylish and practical. The large mirror on the wall makes the space look more spacious. The overall effect is simple and generous, creating a comfortable and relaxing bathroom space.
