The bathroom is the smallest part of the house, so you need to use the space economically. Bathrooms are not hard to design, as their use is pretty straightforward.
The most basic design is to use white. You can hardly go wrong with that. White is a very neutral color and choosing the fixtures are easier. You should also have plenty of storage space for towels, medicine, tissue paper, soap, and other stocks of toiletries you will be storing in the bathroom. You should also have some scents in the bathroom – but nothing to strong. A subtle scent from potpourri or scented candles will do the trick – avoid air freshener smells, since they’re too artificial. You may also opt to use older styles, but be sure that you maintain a balance between old (antique) fixtures and new ones.
