I'd open it above like a 'pass-through' and bring the table out in front of it with a bench under the opening.

With white fixtures, keep your floors and all tile white or a stone that is mostly white. You can paint the walls above the wainscot (which might be glossy painted wood or beadboard, or you might employ a cabinet for the sink that was painted a very soft sky blue. One narrow trim piece of tile running through the white tile might be the same tone of sky blue. Then, add blue linens / towels / etc. [houzz=] Now, consider what other colors are in your home and select one that is clear and soft and lovely with white. You might use that color instead of sky blue. I used sky blue because it is the color of water and therefore always appropriate in the bath, but you can make the bath flow with the colors you have or plan to have in your home. If this was a master bathroom instead of a common or guest bath, I would shift the choices of stone and tile from white plus white to a lovely off-white, cream, or almond tone - like travertine. Use a neutral like chocolate on the cabinet and add color only with linens and perhaps some art on the wall. [houzz=]

a much taller head board, something to soften up the cabinets. the bench at the end needs new fabric, and possible paint raise the bed with risers on the feet. warm neutral tones.

Hi Tanmayi, Going for white walls is always safe, this will helps in giving a light feel to the room plus gives a lot of scope to bring in the patters and colours to the room in other forms (like curtains, cushions, wall art/frames, etc) PAINT SHADE(2 Options) Would also like to advice you to have a subtle wallpaper either in the niche portion of the TV wall or for the entire headboard wall. (Assuming the other walls may have windows or doors) SOME WALLPAPER REFERENCE IMAGES: Later you can gradually bring in other elements as per your taste and time and pull up the room together. Hope this helps! Best Regards, CUBS Team!
