Ye Nai purchased some pretty good shower rooms. They had double-layer panels with an insulation layer in between, and the interior was spacious. Even someone two meters tall could stretch out their arms without any trouble. With a shower curtain dividing the space into two sections, the larger interior area was used for showering, while the smaller exterior area served as a changing room. Both had shelves and hooks for storage, and the ceiling was removable to allow for the installation of lights, powerful heating lamps, fans, and timed water supply switches.
