The separate lavatory is equipped with an electric toilet with grinder. This type of toilet flushes with less water than traditional toilets. Grinding the waste prevents potential clogging of the black water pipe system.

The lavatory is equipped with a silent but powerful exhaust fan, eliminating humidity and unwanted odours. The lavatory is complemented by a large mirror, a compact bamboo hand washing sink and a large overhead cabinet with an integrated 230 V outlet.
