The showers are fairly self-explanatory one lever turning the shower on/off and the other regulating the temperature.  Occasionally, because of the village plumbing infrastructure, there can be a temporary build up of water in the shower tray whilst in use.  This is caused by an airlock which the plumber isn't able to ameliorate, however, the blockage will clear without any action and we have never had a "flood" because the level will fall before that point is reached.  We apologise for any inconvenience that this may cause.
