A double vanity can look good even in small bathrooms but takes up a lot of space that might be better utilized. If additional storage space is just as important to you as the extra sink is, use upright cabinets as a linen closet for towels and toiletries. Selecting a vanity with drawers or open shelving beneath the sink can create storage solutions.
Low-flow toilets, which use 1.6 gallons of water per flush, are required by law in all new and remodeled baths. Pressure-assisted toilets effectively clear the bowl with one flush, but make considerable noise in the process. Gravity models sometimes require two flushes to clean the bowl properly. For maximum efficiency, choose a bowl with a large water surface. Make sure there's sufficient space around the toilet for comfortable access—ideally, at least 16 inches from the centerline of the toilet and walls or fixtures on either side. Also allow at least 30 inches from the front of the toilet to the nearest object.
