If you are weighing up bathroom worktop fitting in Upper Walthamstow, the first thing worth knowing is that the building decides more than the brochure does. Bigger houses on the forest side take proper kitchen-diners of 4m to 5m with a full island of 2.2m plus a separate utility, and specifications run to thicker mitred edges and matching window sills. Rear extensions with bifolds are common, which puts the island as the main working surface because the wall run is interrupted by glazing. If that sounds like guesswork, it is not: it is measured on the day, in your kitchen, before anything is cut.
A hundred and forty years of alterations sit under the current kitchen, and the worktop is what has to sit flat on top of all of it. A vanity top is where all of that turns up in miniature, with the basin, the tap holes and a splash return crowded into a few hundred millimetres of stone. Bathrooms take the same slab and roughly half the width.
The party wall is the straightest surface in the house and everything else has moved away from it over a century. Original boards over shallow joists give under load, so the unit is fixed back to the wall as well as standing on the floor before any stone goes on it. Loft en-suites lose their splash return to the slope.
The archetypes on this patch are Edwardian semi-detached, large bay-fronted villa and 1930s detached house. What is behind the plaster is different in each, and it matters at fixing.
