Looking for Matt black tap ware and showers at the moment seems hard to find and often websites don't have prices which I find annoying

Do you mean charcoal finish render? It's a dark grey oxide that is put into the render so that the colour is built into the render rather than render then paint.

Lime washed in grey? Are you sure that's the look you want to go with? Do you mean an off-white?

Well here you are Marilyn, the final finish. It is a light look, the first photo appears darker than what they appear in real life, it's more like the third photo. I am happy with the look. I have a few issues with the quality of the work with a 'burnt' mark you may see in the first photo and 'boot' marks in other areas. That aside I am happy with the American Oak and Bona Traffic HD Satin. It's not too shiny but has a lovely subtle sheen to it. The Bona Traffic HD is supposed to stop the timber from yellowing or getting darker.
