The Sink

The Sink is a part of the Big Empty in the Fallout: New Vegas add-on Old World Blues.

Layout
The Sink is a one floor area consisting of three adjacent rooms with a central room containing the Sink Central Intelligence Unit. All the sink upgrade units can be found here (Toaster, Light Switch 01, Light Switch 02, Muggy, Biological research station, Blind Diode Jefferson, Sink Auto-Doc, Book Chute and Sink) along with multiple containers in all the rooms. In its entirety the sink contains a workbench, Reloading bench and Hot plate as its usable crafting sources; excluding the use of the sinks units. This area leads to The Sink Balcony, The Think Tank and Big MT.

Upgrades
The Sink can be upgraded by finding the back-up personality holotapes scattered around the Big Empty. Many appliances are available for reactivation and upgrading, including:

Sink Auto-Doc
The Auto-Doc in the Sink is a far superior model to other Auto-Docs, by its multiple functions. It is the only object that offers cosmetic surgery to the Courier and offers several, although pricey, implants after finding them in the Big Empty. The auto-doc will also heal you fully.

Biological research station
The Biological research station is the mojo mac-daddy of all things agricultural. It has the ability to clone any dried plants found in Seed Bags in the Big Empty, and also can process other plant matter into Salient Green, the green goo that can create most any plant desired when accessed at a campfire.

Blind Diode Jefferson
The music-less Juke Box in the Sink is the upgrade hub of all things pertaining to the Sonic emitter. After finding holotapes with certain frequencies in the Big Empty, Jefferson can tune any Sonic Emitter Pistol to that frequency giving the pistol different and unique properties.

Book Chute
The Book Chute is a Communist hating, destroyer of knowledge. It plans to destroy all things that resemble knowledge, and all things which might aid in independent thought; like pencils. After its upgrades it can break down any pre-War book, clean or destroyed, into blank books. It can also break pencils into lead and scrap metal, as well as clipboards into duct tape and scrap metal.

Light Switch 01
The Light Switch 01 is found in the area next to the Toaster, and has a more laid back personality than Light Switch 02. It's second upgrade provides the option for lighting that raises Intelligence and repair skills for 12 hours after exposure.

Light Switch 02
Light Switch 02 located in the Bedroom area possesses an expressed hatred towards Light Switch 01 for its professed superiority of a larger processor. Its upgrade provides the option for lighting that raises Charisma, Barter, and Speech for 12 hours after exposure.

Muggy
The cute miniature Securitron has an addiction for all things relating to dishware, cups, and especially mugs. Its second upgrade allows it to create a small supply of energy cells and scrap electronics once every day.

Sink
The Sink in the Sink is a germiphobe that acts as a source of clean water, and after being upgraded, can fill up any empty bottle with water turning it into purified water, which includes Milk bottles.

Sink Central Intelligence Unit
The Central Intelligence Unit acts as the hub for all the appliances in the Sink. It can turn on or off the personalities in the area leaving them to function in a quieter state. It also acts as the snobbish merchant and repairer of goods and sells certain mods for weapons after their holotapes are found, but it does not restock items like other merchants.

Toaster
An evil Toaster with aspirations of a second Armageddon which can turn plain Saturnite fists into the Saturnite fist super-heated. It can also rip apart other small appliances, such as Cameras, Irons, Hot plates and even other Toasters into their basic components, acting as a source of energy cells and scrap materials for the work bench or reloading bench.

Appearances
The Sink appears only in the Fallout: New Vegas add-on Old World Blues.
