Usage

The Lavatory provides a place for Duplicants to relieve themselves while reducing the spread of Diseases.

It fulfills the 'Flush Toilet' Criteria for a Washroom, providing +2 Morale.

The Lavatory outputs more liquid than it takes in, so it can be used to generate a small amount of Water or Dirt when paired with a Water Sieve. One Duplicant with a normal bladder will produce at least ~11.16 g/s Water, which can be used in an Electrolyzer to cover a ninth of their oxygen intake. However, the amount produced is small enough that to keep an Electrolyzer running non-stop, it would require 52 Duplicants to use the bathroom each cycle, or 90 if the bathroom is also sustained by the toilets' output.

If adding the water produced to your supply, you would have to worry about disinfecting the Polluted Water, which will have millions of germs in them.

Mechanics

The Lavatory uses 5 kg of Water and produces 11.7 kg of Polluted Water, both of which are carried through pipes. The resulting Polluted Water is the combination of the 5kg of input Water temperature and 6.7kg of 37 °C / 98.6 °F newly created Polluted Water, which means the Lavatory will equalize a Bathroom Loop temperature to 37 °C / 98.6 °F over time.

One use of the Lavatory produces 105,000 Food Poisoning germs. These germs are divided among the Duplicant, the Polluted Water, and the Lavatory itself as follows:

Duplicant: +3,350 germs
Polluted Water: +100,000 germs
Lavatory: +1,650 germs

Bionic Duplicants will use a Lavatory (or Outhouse) when no Gunk Extractor is available. This does not use water, but does clog the toilet, requiring it to be unclogged with a Tidying errand. After unclogging, any Gunk expelled will leave through the Lavatories liquid output port.

Tips

Water Sieves do not remove Germs from Polluted Water. It's not recommended to refine Polluted Water from Lavatories and mix it into your main water supply without cleansing it first.
The Lavatory is a recommended upgrade from the Outhouse, as it is more hygienic and does not require Duplicant maintenance.
Having an equal number of wash stations will ensure all Dupes wash their hands. Fewer may cause some Dupes to skip washing if all are in use at the same time.
- This can be made easier with proper Scheduling to ensure less Duplicants are using the washroom at any one time.
Output Polluted Water will be 37 °C / 98.6 °F regardless of input temperature. This can be used to heat or cool Water that's above or below 37 °C / 98.6 °F.
