Remodeling bathroom requires through planning, whether the size of the bathroom is big or small. In fact smaller the bathroom, more the planning it requires in order to transform it into a comfortable place to use. When you plan you should take into consideration whether the bathroom will be used by the family members or by the guests. If the bathroom is to be used by the family members regularly then you have to emphasize your remodeling on the functionality of the bathroom. And if a small number of guests are going to use it occasionally then you can decide more on fashion than function. You have to select fixtures accordingly.
Many homes have separate bathroom for the children. If such a bathroom exists in your home you should think of installing a high capacity toilet. Children have the habit of flushing down anything they fancy down the toilet. Even small toys are not spared. Therefore if you install high capacity toilet the chances of toilet clogging will be much less. Other fixtures in such a bathroom should also be child-proof and long lasting. For ease of cleaning you should consider installing one piece toilet in such a bathroom. Varieties of such one piece toilet are available that are very easy to clean due to the absence of the gap between the seat and the tank.
For your master bedroom bathroom you should replace the old toilet with an efficient model that will use less of water. Similarly, you should replace the sink, shower and tub fixtures. You can remodel the bathroom in such a way that two people can use it at the same time without disturbing each other.
In case you have a shower in your small bathroom, paint the walls with some humidity resistant paint. Wallpapering may add style but will not last long due to moisture and if you have a steam shower the wallpaper will certainly peel off after sometimes. Repapering will be an expensive affair then. To reduce moisture you can install an exhaust fan. Be sure to choose a fan that will remove humidity and stale air efficiently without using much power.
Small bathrooms are darker inside. You can think of installing extra lights in order to brighten up the interior. If the bathroom is primarily for the use of guests you can choose intimate lighting design.
Small bathroom does not mean you have to think small when remodeling. You can have all the features of a big bathroom in it albeit in a limited way. If you search properly you will find ways and means to make it look and feel big.
