But don’t you then have to clean out the washing up bowl AND the sink? So why not just clean the sink?
A washing up bowl is a very British item, it’s something to do with using the water to water plants when finished. I’ve only evenly know my friend and her mum (both with questionable clean sinks!) not to use a washing up bowl.
To me the pros are, you can still poor away liquid like when someone presents you with a half drunk cup of tea to wash up. You can also have something soaking while still being able to use the sink. Also the bowl acts as a portable bucket for when you need water to clean something away from the sink like the oven etc. Also when emptying you don’t need to put your hand in a sink of hot dirty water to get rid of the plug. I give both my washing up bowl and sink a rinse and bleach my sink once a week or so.
They are very cultural and it’s just something I’ve always had and wouldn’t want to no have one. I know they aren’t popular in the US.
