TOILETS Both comfort and style should be considered when choosing a toilet for your new bathroom. Toilet seats come in two basic shapes, rounded and elongated, but they're available in a number of materials. The tank and toilet seat arrangement may be all one piece, or disconnected from each other. When looking at tanks, you may want to take into consideration how much water is used, since less water is both environmentally sound and lowers your water bill. In city apartments, you may install what's called a flush-o-meter toilet. This tank-less toilet gets the water directly from the wall. Another city style toilet is the wall mount toilet. Like the flush-o-meter, the plumbing comes from the wall instead of the floor, and the tank is usually concealed behind the wall.
