Invest in fancy towels.
If you have a small bathroom, don’t worry; there are still plenty of things you can do. Chances are your towels are always visible, and you can use this to your advantage.
You can make them as built-in decor, and while you might not like it at first, trust me, it will grow on you. I think this is one of the main reasons why investing in a minimum of one pair of beautiful and high-quality towels could ultimately upgrade the entire space.
Consider adding some plants.
Plants are always the answer to any of your questions! The majority of spas usually possess a very earthy and natural feel, and you can imitate that with a couple of plants!
A hanging plant closer to the window could truly elevate the space, but if you don’t have a good window in your bathroom, you might want to opt for a spider plant or even a Boston fern (they both thrive in low-light settings).
