Recessed cabinets in the bathroom can increase storage space and decrease clutter and mess. Installing a recessed cabinet isn't difficult, so if you're on a tight budget, install it yourself and save the money that you would pay to a professional. If you're feeling ambitious, you can even build the cabinet rather than buying it from a store.
Buy a Cabinet
You can buy a commercially-made medicine cabinet that's designed to be recessed into a bathroom wall for anywhere from $100 to $400, as of June 2011, depending on how fancy it is and on the quality of the materials used in its manufacture. You may find a vintage medicine cabinet at an architectural salvage store. Depending on its quality and rarity, you could get it cheap or pay a premium for it. Whether you decide to buy new or used, get a cabinet that matches the style and decor of the rest of your bathroom.
Build a Cabinet
Save some money and undertake an interesting project by building your own recessed bathroom cabinet. The materials in a typical cabinet are minimal, so building your own can cost very little and may even be free if you have materials from other projects around the house. All you need is some plywood, a few tempered glass or wood shelves, a mirror and two hinges, and you can put together a cabinet that will look as good as something you would buy in the store.
If you decide to install the recessed cabinet yourself, you will need a utility knife, a measuring tape, a pencil, a saw, a drill and some screws. If you don't already have all these things, you can buy all the tools you need to install your cabinet for less than $100, and you'll have them handy for the next project. If you don't have the time, interest or motivation to go the DIY route, hire a professional and have the job done quickly and easily.
Hiring a Professional
Any professional carpenter could do this project in a few hours. A carpenter will probably charge between $100 and $200 for this job. Because it is quite a simple job, you could find someone who does handyman-type work and isn't a licensed carpenter who could do it for less. Whether you do the job yourself or hire someone else, cut a small hole and inspect the space with a flashlight first to avoid cutting through any electrical wires that may be in the wall.
