Cultural preferences could help you decide over a number of options available in the market. If you are a Muslim offering prayer for 5 times a day, then having access to a tap to wash yourself up quickly before the prayers may become your preference.
To this, you may like having a quick hit-and-close tap at the entrance of your bathroom to save your efforts. Similarly, social living too affects bathroom renovation.
Further, If you are a family with more than five members, then plan more empty space for your bathroom. Make use of free spaces near bathroom window to have special steel hangars for accommodating more stacks of clothes.
Thus, Cultural preference may affect bathroom renovations.
