These are the essentials, but what makes a bathroom likable and colorful is a fun theme. These themes are normally carried through in towel colors and, of course, shower curtains. A shower curtain is the key element in a bathroom theme, as it is a necessary commodity. Not only do shower curtains keep the water coming out of the shower head in the tub and not all over the floor, a shower curtain makes the bathroom usable to more than one person blocking off the view of the person standing under the nozzle. But, the look of the curtain can have the most influence on the buyer. Therefore, there are many reasons for a person to buy or not buy a certain one.
