My baths are pretty quick too, but yours are really just a crow's quick splash.
Literal
I-[also-も] quite bath [attributive-の] time [subject-が] short-but, you [topic-は] truly crow [attributive-の] quick-wash [is-だ]-[agreement-ね].
Built on the idiom 烏の行水 ('crow's bathing'), used to describe a very quick bath — the image is of a crow dipping in water briefly and flying off. Culturally, the normal Japanese bath is a long, relaxing soak, so a fast bath is noteworthy. 結構 ('quite, fairly') is a common degree adverb. けれど ('but, although'). The sentence playfully contrasts the speaker's already-short baths with the listener's even shorter ones.
