How can I drill a hole for concealed cistern toilets?

This is one of the most difficult cuts in any construction work. Whenever possible, you should cut the cistern protection housing to size, apply the ceramic tile with the marks for the location of the housing and use a manual angle grinder to make the cut only after the material has dried.

This technique minimises the risk or breaking parts and is easier to do.

If this is not possible, make the cut using a manual angle grinder with a continuous alloy disc for porcelain stoneware. If the cut is less than 4 cm from the edge of the tile, you may have to use a water jet cutter.
