To keep it simple and clean, install a small glass shelf or 2 of maybe 10mm thick glass and 10-12” x 4” on the side of the shower wall for keeping soaps and shampoos, a watch and specs or a mobile too. Or maybe add a small glass cabinet. These are available or can be easily made to order.

go for full shower area

Hi, I think full wooden tiles will feel like pathetic. Try disparate like combinations of glossy and wood tiles or like 2 walls and floor with wood tiles and other 2 walls light colored glossy tiles to break the monotony.Thank u.

Hi Shivam, I hope you are doing good. There is no particular tile size that may look good as it completely depend kind of design you have in your perspective. If you are looking at more traditional interiors then generally smaller tiles with motifs or emblems look good which have a representative geometrical or floral patterns. If you are looking at more modern interiors then generally bigger tile sizes are preferred for clean look less joints.  Regards, deSigneR
