As far as bathrooms, four would be ideal, but they could survive with three if they had to. 請問 survive 要怎麼翻譯比較好？感謝！?

As far as bathrooms, four would be ideal, but they could survive with three if they had to.
至於浴室，4間是最裡想，但是如果只有3間，他們也能勉強湊合著過去。

survive 在原句中不是 "存活"的語意，而是日子依然過的下去`。
3 [intransitive] to manage to live a normal life even though you have very little money
survive on
I don’t know how you all manage to survive on Jeremy’s salary.
the amount that a family needs each week just to survive

survive = 勉強 可以接受 而活得下來

全句 =
四間浴室 就完美了 但是 要是只有三間的話 他們應該還是勉強 可以接受的.

當然每間都要有三溫暖 還有沖水按摩浴缸 才可以喔!

另例:
On compensations, I would ask for $250K but will survive with $200K + 1M options.
薪資上,我的要求是$250K 但是可以接受$200K 加上 百萬選擇權.

假如不理原本用詞跟譯為中文的相互關係(即是指當看中文時會否看出原文是用了survive這個誇張法寫成的語意)的話，這句we could survive with three if we had to的意思=逼於無奈三間浴室我們唯有勉強接受。

但是用"逆翻譯把中文再轉成英文的檢測原則"看這句譯文，便只會看來英文是說"we accepted with reluctance"...

由於這詞不能"直譯"為「逼於無奈我們有這三間浴室仍是生存的」，因此假如想把原文意譯但仍有少少survive意味的話，試參考以下：

關於浴室的數目(量)，四間會是最理想的，但是假如只有三間的話我們唯有適應吧。
[暗用了「適者生存」的中文人們已習慣聯想到的四字詞]

關於浴室，四問是我的理想數，若受限於空間等因素，免為其難，三閤亦可。survive是困難选擇而不得不做意思。

可以活接受=survive.
