Тут, похоже, игра слов с парфумом от Davidoff:
Hot water и Cold water :)
На русский трудно перевести.
"Что предпочитаете сегодня утром, сэр? Горячую туалетную воду? И, может быть, Холодную воду в качестве финального штриха?"
Но названия обычно не переводятся и игра слов потеряется.

Нет, не игра слов...

"Good morning, sir. Are you ready for your bath, sir? Don't get up — I'll put you in — there. Thank you, sir."
John's pajamas were taken off. He expected to be lifted like a child, but this did not happen. Instead he felt the bed move slowly on its side. Then he began to roll down gently into bath water which was the same temperature as his body.
He was surrounded by a blue aquarium and he could see fish swimming. Sunlight came from above through sea-green glass.
"Would you like hot perfumed water this morning, sir, and perhaps cold water to finish?"
"Yes," agreed John, "as you please."
