The Sims 2: Castaway/Plumbing

Using outhouses fulfils the Bladder need. Showers fill your Sims' Hygiene all the way to the top, unlike swimming in the ocean. In order to build the basic outhouses and showers, you need a good Mechanical Skill, the hammer tool, and lots of rope. To build the more lavish outhouses and showers, you need the chisel tool, a high Mechanical Skill, as well as the Creativity Skill.

''Finally, a private place to take care of business. Now you just need to print up some reading material to help pass the time.''

Functioning Shower
''When was the last time you showered? If you can't remember, then it's high time you built one.''

Lavish Outhouse
This posh outhouse is lacking in nothing, except maybe some unnaturally blue toilet water and a monkey attendant.

''Showers this complex are very difficult to build. If only there was a button you could press to make one magically appear.''
