What is the correct number of electrical points to install in an Australian public washroom? Well there is no definitive amount but here are some guidlines
The amount of hand dryers needed depends on the expected traffic in the washroom. It will also depend upon the type of hand dryer you would like to put into the washroom.
Maybe due to cost or the need to reduce noise you are looking at installing a standard warm air hand dryer with relatively slow dry time of above 30 seconds, then you may potentially need to install additional dryers to cope with the traffic.
In a low use washroom (under 100 uses per day) one warm air hand dryer per four basins will or one high speed hand dryer for every five to seven washbasins. However if those 100 uses are concentrated during very short periods like they often are in factories or entertainment venues then you need to look at how many are needed to cope with this, which could be as many as one per wash basin.
In medium traffic washrooms (100 to 300 uses per day), install one conventional warm air hand dryers for every two hand wash areas or one high speed hand dryer for three or four washbasins. Again consider how the usage is spread throughout the day.
In a heavy use washroom (300 plus uses per day), multiply by two the number of hand dryers, so at least one high speed hand dryer per two washbasins and a one to one ratio for conventional warm air hand dryers. Again this may need to more high speed hand dryers or even Dyson Airblade taps could be a good option.
It is also worth noting that if you have a very high traffic washroom it is a good idea to look at siting hand dryers behind mirrors so the water drains into the sink or blade dryers than can be plumbed in like the D-Flow hand dryer so prevent wet, slippy floors.
In work places with a typical 8 hour working day, employees will typically go to the toilet 4.5 times per day, so up to 22 employees of a single sex will constitute a low traffic washroom and anything over will move into being a medium traffic washroom. Of course you may need to consider how breaks are taken for example shift workers in factories may lead to short term, high traffic periods.
