Royal Bathhouse

Located in the Elkia Royal Castle within the Elkia Kingdom is the Royal Bathhouse. It gains its water from the only local stream within Elkia. It is used in a number of scenes from the anime and light novels, and requires artificial sources like wood and coal in order to keep it warm at all times. It typically is warmed by Steph Dola's Maids.

After the events of the 5th light novel, Sora and Shiro remodeled it into a more traditional Japanese public bathing house.
