I think a feature wall would be fantastic. Given the height of the ceilings - I think the color would look fantastic!

A simple trick I learnt : How to find the exact complementary colour. Get the colour in a strong light.,,,sunlight preferable. Isolate it and stare at it intently for a minute or so, Close both eyes and see if you can see a colour..."reflected" on the inside of your eyelids.....THAT is the colour that will be a good complement for the one you want . In this instance, since the colour is mixed...you might "see" several. Looking at this electronic colour...( not the ideal scenario)...but.what I see is a light greeny/ grey, a swatch of the colour would be easier to do this with. Put the swatch on a white background and....stare,,,,so..."light grey" is close but maybe with a touch of green. Hope it is successful.

I agree paint may be more versatile - but the right wallpaper on a feature wall with that deer head would be so freaking awesome ! Depending on your colour scheme, if you go with a vintage or art deco pattern, fairly subtle and with a slight texture in it, that'll beautifully offset the deer. And if it's the right choice then you won't want to change it for the next few years anyway. So definitely wallpaper - there's some great 'wall candy' around :-) Good Luck !

Hi all! Thanks so much for for the comments. Things look much clearer now :) The other walls will be plain white matt tiles 60x30 cm and the floor very pale matt gray , ceiling white, so very similar look like the photo. Bath tub white free standing, all fitings stainless steel and quite minimal. The vanity might be in light timber but I might keep it white. The mirror will be large (not massive) and will reflect the wall nicely, at the same time will make the room look bigger . I don't renovate the unit for sale, but even if we do down the track the colors/pattenrs are not too striking so I'm sure they will be appealing. The builder had said the same thing about the new types of grouting , so I won't worry too much about it anymore. I've decided to go with the wall behind the tub/shower. With some plants on the window as I have now, I can see it looking qute nice and warm. I personally dislike bathrooms in cream or gray tones that look like hotel bathrooms without character that are there only to serve a purpose. Cheers!
