Little bathroom with big potential!!

Was just at this little industrial looking game place with my boyfriend today. I went to use there bathroom and it was completely unfinished. However I like the tile they already had on the floor and with a little help from the right person (me! lol) it could be a beautiful little bathroom!

Any of these color pallets would actually look great in this bathroom! Just needs a change of lighting and some color and a little design to make this great to look at and use! I am really partial to the flowers those colors are already similar to what is already in the bathroom, so it would just make it pop with that little extra edge, the environment would be warm and welcoming (just what you want when you walk into a bathroom right? lol).
