Separate filtered-water taps
Send the selected tap’s hole diameter, mounting instructions and a photo of the intended position. We check the stone around the opening and the room needed for the tap base, handle, fixing nut and hose below.
Replacing a filter tap
A replacement fitting may use the existing hole or require a larger opening. Supply both the old opening diameter and new specification. The condition of the stone and the replacement base coverage affect what is practical.
Allow for the filter system
Your plumber should confirm the under-sink filter location, connections and hose routing. Space for the drilling and tap fixing is assessed separately from space for the filter equipment. If you are choosing a boiling or chilled system, see the dedicated Zip tap cutout service.

Cutout questions, answered.
Can a filtered-water tap be added beside my existing mixer?
A second hole can be assessed where the stone, spacing and underside access are suitable. Send a photo showing the mixer, sink, splashback and proposed position.
Is a filtered-water tap hole the same as a mixer hole?
Do not assume the sizes match. The required diameter and fixing arrangement come from the exact fitting’s installation instructions.
