It is easy to have a kitchen in mind for bathroom worktop fitting in Walthamstow and no idea yet what your own walls are going to do to it. The dominant job is a Victorian terrace with the side return filled in, giving a kitchen of 3.5m to 4.5m across the back with a rooflight and an island of about 1.8m by 1m. Un-extended houses keep a galley of 2.4m in the back addition, and the town-centre flats have single-wall kitchens of 2.6m. Whichever it is, the process below is the same, and the figure you get after templating is fixed.
Party wall settlement pulls the floor down at one side of the room, so a long run reads level at one end and not at the other. For a vanity the length is rarely the argument, because it is the depth and what has to be drilled through it that set the piece. Bathrooms take the same slab and roughly half the width.
Ceilings in the addition are lower than in the front rooms, so the band of wall between the worktop and the wall units is shorter than the rest of the house suggests. The bathroom in one of these is usually a later addition over the back kitchen, so the walls are thinner, the floor moves and a vanity has to sit level in a room that is not. A large bathroom is where a double vanity becomes possible.
Around here the stock is late-Victorian terrace, Edwardian terrace, 1930s mansion flat and recent town-centre apartment block. They fail in different places, which is why the survey looks at different things.
