Rotherhithe kitchens
The kitchens we meet in Rotherhithe
Before you settle on a material, it is worth understanding how splashback and upstand work in Rotherhithe is shaped by the room it has to go into. The old village cottages near St Mary's have small closed kitchens with 2m to 2.5m runs and a return under the window, while the 1980s dock housing and later riverside blocks give a squarer room with a peninsula dividing kitchen from living space. Guessing at this stage would only put a wrong number in front of you, so we do not do it.
Lath and plaster, a settled floor and a hall with a turn in it are the three things that decide how this job runs. Cutting sockets and switch plates into stone is a workshop operation, so the electrics have to be final before the template. Height off the units, not off the old tiles.
Cottage terraces have no hall to speak of and the front door opens almost straight into the room, which makes the carry easier and the protection harder. Lath-and-plaster on the party wall and the chimney breast returns almost never runs true, so a 100mm upstand bedded on silicone is the honest answer here, it rides the bow and hides the junction the worktop can never close on its own. Dry lining behind a panel needs a fixing plan of its own.
The houses and blocks behind these jobs are Georgian dock cottage, Victorian terrace, 1980s docklands housing and 2000s riverside apartment. A quote that ignores which one you have is guessing.
