What is a Toilet Rough-In and How to Measure It? A Complete Guide for Your Smart Toilet Upgrade

什麼是「去水位」?選購 BBbidet 智能廁所前的關鍵測量

準備為浴室升級?在選購 BBbidet 智能座廁之前,最重要的一步不是挑選功能,而是精確測量去水位(Rough-in)

簡單來說,「去水位」是指牆壁與排污管中心點之間的距離。如果測量錯誤,座廁可能無法安裝,或者安裝後與牆壁之間出現難看的空隙。

1. 地去水(S-Trap / 地排)測量方法

如果你的座廁排污口是直入地面的,這就是「地排」。請跟著以下步驟測量:

  1. 找出中心點: 找到座廁底部兩側固定在地面上的螺絲蓋。

  2. 由牆起計: 從座廁後方的已鋪磚牆面開始量度,一直拉到螺絲蓋的中心點。

  3. 注意事項: 必須從磁磚面開始量度,而不是踢腳線(地腳線),這樣才能確保座廁安裝後完美貼牆。

    • 香港常見尺寸: 通常為 12 吋(305mm)或 15 吋(400mm)。

2. 牆去水(P-Trap / 牆排)測量方法

如果你的排污管是穿過牆壁排走的,你需要測量的是去水高度:

  1. 由地起計:已鋪磚的地面向上量度,直到牆上排污管的中心位置。

  2. 香港常見標準:

    • 低咀(Low-level): 中心點高度大約為 100mm(4 吋)。

    • 高咀(High-level): 中心點高度大約為 180mm(7 吋)。

了解這個高度,能確保你的 BBbidet 與家居佈局無縫連接。
