Draw each run separately
Sketch the kitchen from above. Label the main wall runs A, B and C, then add any island or peninsula as a separate piece. Note the approximate length and depth of each in millimetres, using the same units throughout.
Mark the sink, hob and any change in depth. Add doors, tall cabinets and corners to make the sketch easier to understand. Write “approximate dimensions for estimate only” on the drawing.
Record the visible details
Mark exposed edges and where the worktop meets a wall. Note whether you want an upstand, splashback, breakfast bar or waterfall end. These details help a prospective fabricator ask the right follow-up questions.
Photograph the whole room, then the sink area, corners and junctions with existing tiles. Keep appliance model numbers with the sketch if you know them. You do not need to upload photographs to this website.
Leave manufacture to the appointed fabricator
Do not dismantle the kitchen or move heavy components to collect an initial measurement. Leave anything you cannot safely measure as unknown and ask for it to be checked during a visit.
A chosen fabricator will establish its own measurement and approval process. If a sketch or layout changes, issue a new dated version and make sure everyone involved uses it.
If your layout includes a new island, read about kitchen and island worktops before finalising your first brief.
Common questions
What if I do not have every measurement?
Use the information you can safely gather and mark the rest as unknown. An incomplete but clearly labelled sketch is more useful than invented precision.
