I completely forgot to update here, as I still haven't managed to take decent photos of it, but I found my tile solution for the cloakroom. I had always like crackle glaze tiles and wanted them for my kitchen splashbacks, but could never afford them. Then I found an end of line pallet deal and so ended up buying a large quantity, way more than I needed for the kitchen. They are cream and worked perfectly on the cloakroom walls too.
Next, I umm-ed and ah-ed about which colour to paint the door, trying unsuccessfully to find a blue that coordinated with the floor tiles. In the end, I realised that I had paint for the woodwork in one of the bedrooms in a colour that worked perfectly and also wasn't too dark for the small, windowless space.
People just adore this little cloakroom. I get so many compliments on it. Way more than for the rather fancy wetroom I did next to it. I will try again to take some decent photos so I can post them.
