At some times of day it takes a while for the hot water to flow to the hot taps. Please be patient as it's a large house.
If lots of people have baths and showers the hot water might run out, but it will replenish within 45 mins in most cases.
The hot water flow pressure can deal with up to two showers or baths running at the same time, so please don't try to turn on all showers/baths at same time.
If you encounter issues with hot water running out, please let your host know.
The top floor ensuite shower to bedroom 4 is controlled via:
Top knob adjusts the flow to the ceiling mounted shower head
Middle know adjusts temperature, set to around 10 o'clock for a nice warm shower, or 9 o'clock for a hot shower (caution needed to avoid burning)
Bottom knob adjusts the flow to the hand-held shower head
