Less we all swoon and gush about things Roman (pasta, art, antiquities, fashion) let us not forget the cursed Roman shower and hot water tank. Noting has changed in 30 years except that now the shower stalls are big enough that if you drop the soap, you can avoid the water spray which cycles from cold to scalding in 15 second cycles, without having being scalded.  (Susan informs me their shower is small, but they never drop the soap)
