Big Fish Spa

Big Fish is a men's bathhouse, sauna and spa at 207/20/1 Nguyễn Văn Đậu in Bình Thạnh, run under the Nấm Spa name. Gay Travel Navi reviewed it in December 2025 and describes a wellness-led place, not a cruising sauna, so pick something else if that's what you're after. The same review gives entry by time of day: 200,000 VND from 12:00 to 16:00, 300,000 from 16:00 to 19:00, and 150,000 from 19:00 to 22:00. Google rates it 4.7 from about 73 reviews. The Facebook page (bigfishspa) is the place to check for changes.
