Every couple seems to long for double sinks when they are looking for a new home but what they don't know is that the double sinks are the beginning of the Great Divide...dividing themselves from being a close couple to increasing the space between themselves. With one sink to use, couples have to dance around each other and remain close, engulfed in each other's personal space as it is one shared space. When there are 2 sinks and especially when the sinks are on opposite sides of the bathroom, the couple no longer shares a space. Each person gets their own space and the once close couple is now divided.
Other superficial cons of having double sinks:
More to clean
More things to break
More cost to have repaired
Less counter space
