One of the most popular solutions is to simply knock off one side. This will allow you to expand in one direction and get more space. The problem though is that this solution is not cheap. Aside from spending a lot to reconstruct a new wall, you would also have to consider paying for extensive changes in plumbing and wiring.
Choose Small
You may not be able to afford major bathroom renovation. If this is so, you can keep your existing walls and change the contents of your bathroom instead. Take a look at how huge your fixtures may be. If you are a small or average sized person, you may do just as well with smaller fixtures. Pick a tub, toilet, storage bins, faucets and sink that are smaller than usual.
Choose Free Floating
You may have storage spaces beneath sinks, vanities and anywhere else on the floor. These can further limit the space you can move around on. Do away with the storage areas on the floor. You may instead opt for free floating ones. These include small overhead cabinets, metal racks and hampers that can hang on hooks. Your sink can also be free floating so you can save floor space.
Use Light Colors on Everything
Small bathroom remodeling will not be complete without a new coat of paint. One technique is to avoid dark colors. Choose lighter ones and pair that with equally light colored tiles and fixtures. The light color will not just be soothing. It can also help create the impression that you really have more space. If you want to paint some designs, choose those that aren't too large.
Use Light
Use artificial or natural light to create the impression of expansiveness. It is always great if you can simply cut out a large top window. If this puts you in danger of being seen from outside, you can use bright lighting instead. Have a dimmer installed so you can create softer light when your mood calls for it.
Use Mirrors
This is an age old technique that works well for small bathrooms. Wide mirrors in both walls can make bathroom users feel like there is an endless supply of space. Don't overdo the mirror trick though. It can be quite disorienting looking through so many reflective surfaces.
Push Your Fixtures
Whenever possible, the back of your fixtures should be set securely to the wall. There shouldn't be spaces in between your bath tub or your toilet and the wall. Aside from using every square of space in sight, you can also choose corner fixtures. Your sink and shower stall may be set on a corner.
Small bathroom remodeling can actually be a lot of fun. The real key is to simply change viewer perspective and utilize every available space you have.
