(I made this a while ago for the Oxford Whosoc meme group, am reposting here because I still like it.)
I personally headcannon the TARDIS kitchen to be little more than a small, rather tired looking kitchenette. It has: a stainless steel sink, under which is a few bins; some rather tired laminate countertops; overhead cupboards along the wall that match the coutertops; and a half height fridge under the counter. The floor is a grey linoleum, and the lights are warm and flourescent. By the kettle, there are some jars with “Tea” and “Sugar” and such like on them. Nearby is a large-ish teapot, that could possibly do with a clean, but is hidden by the associated teacosy. The teacosy is the only element of the kitchenette that changes with the Doctor. The following is what I think the teacosies look like.
[ID: 8 pictures in a two by four rectangle. The first row has the first doctor, and a yellow and green striped teacosy with a pom pom on top. The second row is the second Doctor, and rather ornate but old looking embroidered teacosy. The Third row has the Third Doctor, then a yellow velvet teacosy with a bee on it. The fourth row has the Fourth Doctor and a snail teacosy, with brought coloured stripes, on a white teapot. \End ID]
[ID: 8 pictures in a two by four rectangle. The first row has the 5th doctor, then a rather plain beige teacosy with three cups of tea on it. The second row has the sixth doctor, then a knitted bee tea cosy. The third row has the seventh doctor, then an embroidered teacosy that looks like a small cottage, with purple flowers all over the front. The fourth row has the eighth doctor, then a knitted teacosy in deep reds, greens and creams, with a knitted rose on top. \EndID]
[ID: 10 pictures in a two by five rectangle. The first row has the ninth doctor, and then a very simple combat green teacosy with white writing saying “tea” on a blue teapot. The second row has the tenth doctor, then a pineapple teacosy on a black teapot. The third row has the eleventh doctor, then two chevron knitted teacosies in black, pink and yellow with yellow and black pom poms. The fourth row has the twelfth doctor, then a grey knitted teacosy with a knitted fox on top with a large fluffy tail. The fifth row has the thirteenth doctor, then a knitted frog teacosy in green, with a red mouth, big eyes and a yellow crown. \EndID]
