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.

How to make a floor plan:

With the help of a tape measure, measure the long side and the short side of your bathroom.
Create a simple drawing and write down the measures.
Also add structures: doors, windows and sanitary items.
If you want you can also add measures for doors and windows and their distance from the wall.
If you want to remove any sanitary ware please mark with an X.
The more information you add, more accurate your bathroom will be.
