Ummm worktops we got slate from the Reclaimation yard. That was about £300
We did the tiling ourselves so about £300 for adhesive / grout / tiles
We had to have more sockets put in and the extractor fan (which came with the kitchen) and switches for the dishwasher / oven / lights under the cabinets. That was about £200 (including nice sockets rather than shit plastic ones)
The fitter was about £1000 but that included opening up an old serving hatch into a big rectangle and making a little end piece to fill a gap and hold chopping boards and the under sink cupboard
Walls skimmed: about £150
Lovely big ceramic sink off eBay £60
Nice new brass knobs were cheap as chips from China
Bought a very nice tap about £200 I think
We already had appliances
Painted the cabinets and walls ourselves
It was 2 or 3 years ago. I thought at the time it cost about £3k though it took a while with us doing bits ourselves and I stopped adding up after a while
It looks pretty good. We splashed out on lovely tiles for the only bit of wall that is tiled (behind the cooker) and the posh tap which I think makes it look a bit more fancy
I’ll try to find a pic but I’m in the bath 🛀
