【裝修必讀】智能馬桶安裝全攻略:空間預留、坑距與水電位圖解

智能馬桶能提升生活品質,但要裝得美觀又好用,前期的泥水水電工程必須精準配合。特別是香港浴室空間普遍有限,一丁點的尺寸誤差都可能導致馬桶「頂門」或無法安裝。

以下為大家總結智能馬桶安裝的 4 大關鍵細節:


1. 空間尺寸預留:告別擁擠感

香港浴室寸金尺土,合理的動線規劃至關重要:

  • 寬度預留:市售馬桶寬度約 36–43cm。建議左右兩側整體預留至少 80cm 的寬度(即馬桶中心點向左右各留 40cm),如廁時才不會感到局促。

  • 長度預留:一般馬桶長度為 65–75cm。也有小戶型52cm長度的智能馬桶,建議馬桶前方預留至少 45cm(整體長度建議 ≥120cm),確保雙腿有活動空間。

  • 門扇考慮:若馬桶靠近廁所門,必須確認門扇開啟時不會碰撞馬桶。若空間極度狹窄,可考慮改用推拉門(趟門)


2. 坑距預留:精準對位不浪費

「坑距」是指排污口中心點到牆面(已貼磚)的距離。選擇錯誤的坑距會導致馬桶後方縫隙過大或根本裝不下。

  • 主流標準:香港市面上主要分為 305mm400mm 兩種規格。

    • 距離在 295–390mm 之間:選擇 305mm 坑距。

    • 距離在 390mm 以上:選擇 400mm 坑距。

  • 靠牆預留建議(計及磁磚厚度後):

    • 305 坑距:建議實際預留 ≥330mm

    • 400 坑距:建議實際預留 ≥430mm


3. 水電掣位佈局:美觀與實用並重

智能馬桶需要取水及用電,掣位排佈建議如下:

  • 方案 A:左水右電(最常見) 以排污口中心點為基準,水掣(角閥)插座分別向左、右偏移至少 20–25cm。這樣可避免馬桶背板頂到掣位。

    • 高度建議:預留離地 30–40cm。太高會導致電線外露,影響美觀。

    • 噴槍配置:如需加裝噴槍,建議使用雙出水角閥,但需額外考慮其厚度,預留空間要相應加大。

  • 方案 B:水電同邊 若必須裝在同一側,請遵循**「水下電上」**原則,並距離排污口中心點 20cm 以上,確保安全並方便插拔。


4. 排污管預留:防臭與防漏的關鍵

這是最容易被忽略但最重要的一環:

  • 預留高度:排污口應高出地面(飾面磚)約 2cm,方便師傅安裝法蘭圈(密封圈)時進行精準切割。

  • 安裝禁忌:排污管絕對不能低於磁磚面!若管道過低,馬桶與法蘭圈無法達到完全密封,日後極易出現漏水、返臭及滲污等棘手問題。


結語:細節決定成敗

一部好的智能馬桶,需要配合標準的安裝工程才能發揮最大功效。在進行浴室翻新前,請務必與裝修師傅確認好以上尺寸。
