Skanda Purana — Nagara Khanda, Shloka 33
निशायां चैव न स्नायात्संध्यायां ग्रहणं विना । उष्णोदकेन न स्नानं रात्रौ शुद्धिर्न जायते
niśāyāṃ caiva na snāyātsaṃdhyāyāṃ grahaṇaṃ vinā | uṣṇodakena na snānaṃ rātrau śuddhirna jāyate
Jangan mandi pada malam hari, dan jangan pula pada waktu sandhyā (senja)—kecuali saat gerhana. Jangan mandi dengan air panas; pada malam hari kesucian tidak timbul (dari mandi demikian).
Brahmā (in Brahma–Nārada dialogue; inferred from chapter colophon context)
Type: ghat
Listener: Pilgrim audience receiving ācāra constraints
Scene: A ghāṭa at twilight/night with a cautionary atmosphere; a bright eclipse scene shows the exception—pilgrims bathe under a darkened sun/moon while priests chant; hot-water vessel is shown crossed out symbolically.
FAQs

No single site is named in the verse; it gives general snāna-vidhi within a tīrthamāhātmya context.
Avoid bathing at night or at sandhyā; allow an exception at eclipse-time; avoid hot-water bathing in this context.
