For bathroom shower walls, consider using large tiles or panels for a modern look and fewer grout lines. Mosaic or patterned tiles can add visual interest and create a focal point. Incorporate built-in niches or shelves for storage, and use waterproof paint or tiles to protect against moisture. For a luxurious touch, try using natural stone or glass tiles.
