To choose the right toilet for your bathroom, consider things such as the available space, your budget, and your preferences. Measure the rough-in distance (the distance from the wall to the center of the drainpipe) to ensure proper fit. Decide on features like bowl shape (round or elongated), flushing mechanism (gravity-fed or pressure-assisted), and height (standard or comfort). Consider water efficiency by choosing a toilet with a WaterSense label, indicating it meets EPA standards for water conservation. Finally, select a design that complements your bathroom's aesthetic.
