Having been in five different countries in the past couple of months, and three more coming up, staying in a dozen homes and hotels, we've experienced a lot of variation in shower water pressure.
My favorite is Geneva where the pressure is strong and the temperature fairly consistent.
My least favorite is Argèles-sur-mer in July and August when the village is flooded with tourists and the pressure can at times drop to a trickle. However, the touristas do bring money into the village, which enables the local merchants to survive year-round, for which we are grateful. Like yesterday when I needed mozzarella to make a pizza and could dash about 50 metres down the street to the green grocer and be back in less than five minutes.
Now that the tourists are gone, not only does the village have a very different dynamic of mostly locals, the water pressure is more than adequate. I can stand in the shower long enough to get some serious thinking done.
Just, please, don't turn on the dishwasher while I'm in there.
