As advantages of washiki compared with yoshiki (Western style), we can say that washiki is easy to clean and cheap to install, and that the basin tank where feces are primarily piled up is made shallow so the splashing during defecation is weak, and that the quantity of water needed for cleaning each time is small (however, nowadays, water-saving western style urinal which needs less water than washiki for cleaning is sold), and that there is no contact with a toilet seat, which gives a clean impression (however, see the corresponding point in yoshiki).
洋式と比べた場合の和式の利点としては、清掃が容易、設置費用が安い、糞が1次的に溜まる槽を浅く作ってあるので排便時に水が跳ねにくい、1回ごとの洗浄水の必要量が少ない（ただし、最近では和式よりも少ない水量で洗浄できる節水型洋式便器も出回っている）、便座への接触がないため清潔な印象を与える（ただし洋式の該当箇所も参照）といった点がある。
