A bidet spray should be easy to reach while seated on the WC. Its position is therefore chosen together with the WC location, preferred hand, furniture and hose length. The spray holder, water outlet and mixer controls need not be at the same point.
One universal wall connection height cannot be treated as every manufacturer's standard. Before drilling, check reach on site and leave the hose in a tidy position. The selected set's documentation defines the exact connection and installation conditions.
Water shut-off is important. For example, Omnires states in the instructions for a specific bidet spray set that the supply should be closed using the mixer or shut-off valve after use. The handset's STOP button alone should not be treated as a universal long-term shut-off solution. S25
Backflow and water contamination risk also need assessing. The manufacturer's data may specify particular protection under EN 1717, but a marking on one component does not prove the suitability of an entire system assembled in any way. S24
Before ordering: provide the exact set model. Ask how the water is controlled, how it is shut off after use and what protection is provided for the specific connection.
