Keep it simple
Simple and understated finishes that don’t rely on trendy color accents help a room to feel timeless and prevent the space from becoming outdated. Tile especially is a highly durable material that can last 100 years or longer, so using a classic, subtle color improves the chances that it won’t need to be replaced for a long time.
I believe a bathroom should be a calming space, so I avoid a lot of colors, textures, and patterns. For this bath, I suggested off-white and light neutral tones for the walls and ceiling, including the tile, window trim, and wall color. That goes for the commode as well—I almost always choose a white toilet, either a dual-flush or ultralow-flow model. I would also paint the linen cabinet to match the wall tile so that it blends in. Together, these neutral surfaces create a clean canvas that allows other elements of the room, such as the vanity, to stand out.
The vanity serves as the main focus of the room. You don’t want more than one accent element competing for your attention in a bathroom of this size. I suggested a maple vanity cabinet, with a countertop of a complementary tone and color. This acts as the “paint” on the canvas of the room and highlights the natural variation of the wood grain against the more solid-toned walls. Alternatively, a darker walnut tone would provide a higher contrast and more modern look.
Again, for simplicity’s sake, I recommend classic metal finishes such as chrome or stainless steel on faucets, showerheads, cabinet hardware, and bath accessories. All these metal finishes should match so that they tie the room together. Don’t experiment with brushed nickel at plumbing fixtures and polished chrome for your bath accessories. Ideally, any metal on the light fixture will match as well. If this palette seems a bit boring, consider adding more color or interest to the room with your towels, soaps, and other objects, rather than doing so with the fixtures, paint, or tile.
