Art, plants, the unexpected, simplicity.
Replacing tile, flooring, and the major pieces that make up a bathroom—the tub, the toilet, the sink, the showerstall—require serious investments of money, time, and energy.
There are other things you can do quickly.
The first is to pare back the clutter that bathrooms accumulate so easily, leaving out only those things that get daily use and need daylight. By creating more space and simplifying, you're setting up something like a blank canvas for the new things you'll be adding to pop, as well as giving yourself the mental clarity you need starting your day or winding down before bed with your self-care rituals. Without this step—decluttering and finding out-of-sight but accessible places for the variety of products used there—none of the other ones will matter.
The next is to add something green. Some plants thrive in this environment. Orchids in particular hardly need more than the regular steam of a hot shower. Succulents are low-maintenance and on-trend. Placing a potted green friend in your bathroom contributes color and dimension to a space that often runs the risk of being neutral to the point of bland and clean to the point of sterile.
Even the pot can add dramatic interest. While it takes serious commitment to install terracotta tile, you can bring earthy warmth, a pop of color, and something unexpected with something like the cool rolling flower pot by Crowdyhouse.
Art elevates any space. Find a piece that you love and, giving due consideration to how moisture might affect the work over time, place it near the mirror or anywhere there's enough room for it.
A dash of the unexpected always reinvigorates a space or takes it to the next level. Figure out what that might look like for you. In the bathroom pictured above, the presence of a dark-stained traditional wood table is one of a few different elements, along with the painting and the choice to illuminate with a pendant.
