The bathroom is one of the most highly trafficked rooms in the home, which means two things: it should be clean and appealing to anyone who enters; yet, in reality, it tends to acquire more clutter than any other space. Oddly enough, when designing a bathroom, organization tends to be the last thing on people's minds. People center on the tub, the shower, the sink, the flooring and the walls. But in order to bring attention to these focal points you have remove all the other distractions: the toothbrush holders, the scattered lotions and makeup, the shampoos and hair gels, and the stray cough syrups and aspirin containers. So where do you put it all while still making the room functional? The solution is concealed storage units, and medicine cabinets can help provide the perfect camouflage.
Expand the Space
Bathroom medicine cabinets can make any space appear larger. Instead of using awkward cabinetry, shelving systems, or linen closets in other parts of the house, a medicine cabinet is like having a tiny pantry right above your sink
Clutter Control: By storing away all the small unnecessary items and personal affects, your bathroom will not only seem spotless, it will also make the space appear larger.
Magical Reflections: Many medicine cabinets come with mirrored doors, which tend to brighten up the space. Plus, reflective surfaces, once again, make a room seem bigger than it really is.
Recessed Surfaces: Medicine cabinets often jut out from the wall and, in a small bathroom, this tiny additional could cramp a space. But now many can actually be recessed into the wall, so what appears to simply be a hanging mirror is actually a secret storage space.
Alternative Locations
Due to its mirrored door and easy access, many people install bathroom medicine cabinets directly above the sink. However, if this doesn't fit your design goals, these units can be used in many different ways. A plain bathroom wall cabinet can appear over the toilet to store rolls of toilet paper or other items. If you have a window, picture, or a small space above your sink, maybe put a bathroom wall cabinet to the side of the sink to retain easy usability. Then buy a door with an inside mirror: this way you can open up the unit when you need to shave or brush your hair without having to rely on a permanent mirror.
Organization Suggestions
The largest problem is that these storage units can also become cluttered. Here are some quick suggestions to keep your bathroom medicine cabinet organized:
1) Only store items that are used everyday. For instance, not all medicine has to stay in a medicine cabinet. Put all the rarely used band-aids, medications, and ointments somewhere else in the house to keep the space clean and usable.
2) If you do keep regularly used medical supplies in the unit, try to create a separate shelf for these particular items. And if you have children, it may not be a bad idea to buy a unit that has a lock and key option.
3) You probably share this space with a partner or other family members, so make sure each person has their own shelf to keep things separate and personalized.
4) Finally, make sure you revisit it. Every few months things may have built up, so it's a good idea to clean out the unit to make sure it stays organized.
