I am sorry to say but Allure vinyl is not suitable for vertical applications. There are several alternatives to achieve a distinctive wall. Here is a link to a variety of wainscoting, some are available in pvc which may be a good choose for a bathroom others have a wood look. Below is just one example.
Another is to use textured paint or faux finishes with paint. The following is a project guide for Faux painting with a sponge. You can use other applicators like feathers, bush strokes, combs etc.
As far as choosing a color I would take your photo to the Home Depot paint department and one of the knowledgeable associates there can help with your paint selection or take a look at the following Paint project guides.
Thanks for your inquiry.
