How long can I use the same water?
A wood-fired hot tub is traditionally emptied of water and cleaned after every use for hygienic reasons. However, many customers use the same bathing water for a few days by applying certain best practices i.e. taking a quick shower beforehand and keeping a lid or cover on the hot tub in-between sessions. Adding some chlorine or similar antibacterial can extend the use of the bathing water a few days more.
Alternatively, the Skargards filtration system allows you to keep the same bathing water for multiple weeks.
