Colours. There are unlimited colours to pick from too with bathroom basins so take your time to find one you really like. There is no right or wrong choice, so find something that works well for the look you wish to portray in your bathroom. This is a change that can be part of a huge remodel or it can be the only part of that room you plan to change.
The price for bathroom basins will vary based on brand, the type of product, and the materials they are made from. Comparison shop to get a great overall deal. Don't cut corners though on the quality and end up with a product you have to replace again soon down the road. However, don't pay a price beyond what you must in order to get something that is well made.
When examining modern bathroom design, wall-hung furniture has to get a mention. White gloss will never go out of fashion, but more recently furniture finishes such as wenge, beech and maple have made a real emergence in popularity.
