一、凈水器龍頭開孔尺寸有多大

凈水器龍頭開孔(kong)(kong)尺寸在(zai)15-20mm。可以利用臺盆(pen)（不銹鋼(gang)）上(shang)已(yi)有(you)的皂(zao)液(ye)孔(kong)(kong)進行安裝(zhuang)，如果(guo)沒有(you)皂(zao)液(ye)孔(kong)(kong)需單獨開孔(kong)(kong)安裝(zhuang)，凈水器龍頭開孔(kong)(kong)尺寸在(zai)15-20mm即(ji)可。如果(guo)客(ke)戶(hu)是大理石或者陶瓷臺面(mian)或水盆(pen)建議客(ke)戶(hu)自行開孔(kong)(kong)，因(yin)為(wei)此(ci)類材質打孔(kong)(kong)難度較大。

標準的安裝臺面鉆的安裝孔應該是直徑35mm的。安(an)裝(zhuang)龍頭時(shi)水槽開孔(kong)(kong)一般直徑(jing)在15至18毫米，是(shi)指在廚柜(ju)臺面上(shang)開一孔(kong)(kong)，放(fang)(fang)置洗菜盆，該孔(kong)(kong)的長度是(shi)700毫米，寬(kuan)度是(shi)450毫米，圓角半徑(jing)是(shi)37毫米，只(zhi)有按(an)此尺寸開孔(kong)(kong)，才能把盆放(fang)(fang)得進去(qu)。
