Floors are a type of construction that cover the natural terrain with an artificial surface. Floors do not prevent other constructions to be built on top of them. There are many types of floor, with different resource costs, flammabilities, beauties, cleanlinesses, and other effects.

Effects

Constructed floors can bring benefits such as increased movement speed, beauty, and cleanliness, as well as preventing wild plants from growing and fire from spreading.

Movement speed

Natural soil allows the growth of vegetation such as tall grass, bushes, and brambles, all of which cause a walking speed reduction for Colonists. Trees prevent movement altogether, and also prevent roofs from being built over them. Other natural surfaces incapable of growing vegetation such as raw stone, sand or ice also have lower movement speeds. Flooring a frequent path will reduce the time required to walk between the two areas.

Different flooring (and unfloored areas) in different locations

Beauty

Colonists are affected by the beauty of the surrounding flooring in two ways - directly, by the Beauty status level, and indirectly, by the effect of beauty on the impressiveness of some room types. Colonists have mood effects from the beauty of their direct surroundings, especially those locations where they spend most of the day or night such as a bedroom, kitchen, workshop, research lab, etc. See the Beauty page for further details.

The total beauty of a room also affects its impressiveness, which contributes to the mood benefit of rooms such as bedrooms, dining rooms, rec rooms, and hospitals. See the Room stats page for further details.

Different floors can also be used for purely aesthetic purposes as per player preference, or to color-designate different rooms for different purposes.

Cleanliness

Flooring is an important factor when calculating a room's Cleanliness, which is important for most rooms but particularly for kitchens, hospitals and laboratories.

This is done in two ways. First, it covers up the existing terrain which almost always has a cleanliness penalty, and prevents that penalty from applying to the room. Second some floor types have a cleanliness bonus which further improves the cleanliness.

Flooring rooms and areas surrounding rooms where cleanliness is important prevents filth being tracked from the terrain there into the clean room as will happen for the first ?? tiles after transitioning from dirt to flooring.^{[Detail Needed]} Non-straw matting floors will not prevent the creation of filth from other sources however, such as that created by animals, but may ameliorate the loss through their other increases to cleanliness.

Cleanliness improves success rates in hospitals as they help prevent the possibility of infection. It also affects research speed and the chance for food to cause food poisoning.

Cleaning time

Main article: Cleaning Time Multiplier

Different floors take different amounts of time to clean ranging from 60% to 200%. While most metal floors are cleaned at 60% of the usual time, floors made out of stone blocks and the other metal floors take 80% of the time. All types of carpet have the longest cleaning time at 200% with the remaining floors at 100%.

Flammability

Non-flammable flooring helps prevent fire advance to its tile.

No plant growth

Any flooring placed outdoors will prevent grass, bushes or trees from spreading there. This can be useful to keep any trees from growing in the path of a wind turbine and reducing its power output. Surrounding fields with flooring will prevent trees growing there, which your growers must clear first before they sow nearby. It can also be used to create fire breaks to keep wildfires from spreading to your base if non-flammable materials were used.

Flooring can even help with security in certain biomes. While giving a movement bonus to raiders, covering your killbox in flooring will prevent any trees growing there for raiders to take cover behind.

Removing floors

Floors can be removed with the Remove floor order, which is found under the Architect/Floors tab. After floors are removed, the tile will retain its old terrain type.

Most floors return, on average, half of the resources spent at construction when removed. This can be a useful source of materials when raiding settlements or temporary camps, or simply a way to recycle unneeded floors in your own colony. Notable exceptions include flagstone, burned floors and smoothed floors.
