With a nice clean space like that you can go a lot of different ways. I would start by looking at shower curtains, because they can become the focal point. When you find one or two (or more) that you like, you can play off of the colors in the curtain to find the color towels, bath mat, and even wall color. Some ideas: You could go classic black and white, with a touch of something bright if you want for an accent (like the fuscia in the photo) Or something "spa-like," in acqua and cream. Or you could go bright, with teal and lime green. Another classic look: tan walls, white and/or tan towels and bathmat, simple white accessories. Good luck!

I don't think it would be able to work with the rest of the bathroom unfortunately. What did you decide to do?

If you can narrow the linen cupboard, then you do do a similar layout to that GB has shown but with a changed door swing, swap the basin and WC, putting the WC on the wall beside the door so the WC is concealed behind the door.

Sorry the main bathroom (beside the lounge area). I have the ensuite sorted. We'd like a bath in the main bathroom, shower, toilet and vanity. Ideally I don't want the toilet on the wall that separates the bathroom and lounge....bit uncomfortable for guests going loo when we are in the lounge watching TV!
