Is Hong Kong sauna the same as Macau?

It's different. According to Hupu Community, Hong Kong sauna facilities are usually located in some commercial clubs, hotels, fitness centers or hot spring resorts. People can make an appointment or buy services in these places, and then use sauna facilities under the specified arrangements. Sauna services in Macao can be found in some high-end hotels, hot spring resorts or health centers. Macau is famous for its luxury resorts, so it may offer more luxurious options in sauna service.
