Sterile tile is one of the many floors that you can construct. It has the highest cleanliness stat of 0.6. It also takes 60% of the time to clean.

Acquisition

Sterile tiles can be constructed once the Sterile materials research project has been completed. Each tile requires 3 Steel, 12 Silvers, 1,600 ticks (26.67 secs) of work, and a Construction skill of 6.

This tile is relatively slow to construct, taking almost 19x longer than a standard wood floor.

Analysis

Cleanliness is useful for a few different types of buildings:

Hospitals. In a full room of sterile tiles, surgery success is increased by roughly x1.05, while tend quality also increases. And, infection chance per wound is multiplied by 30%, compared to 50% at 0 Cleanliness. These factors can all save a pawns life, so sterile tiles should be installed as you can afford it.
Research rooms. Researching is accelerated in a clean room. A full room of sterile tiles makes research +9% faster. Not a priority by any means, but useful if you have plenty of spare resources.
Kitchens. Cooking in a dirty room has a chance to give food poisoning. However, the cleanliness must be below -2.0 for the chance to exist. Therefore, straw matting or even dirt floor is sufficiently clean. They prevent 95% or 100% of accumulated dirt, respectively, which makes up for the loss of cleanliness.
Biosculpter pods. Pods run up to +15% faster in a full, sterile room. As room space doesn't matter, you can make a 2x3 room with just the pod inside it, which

Cleanliness will also increase room impressiveness. However, using sculptures with concrete, paved tiles, or steel tiles is typically more efficient. Sculptures also increase the Beauty need, which by itself will make colonists happy. Concrete and paved tiles have a clean time of 80%, and steel tiles match the sterile tiles' 60% cleaning.

Room creation

As sterile tiles are expensive, you may want to combine hospitals and research rooms to make the most out of the buff. Otherwise, it's best to make hospitals small, to save on resources. The smallest room size to maintain cleanliness for triage is 4x5, but a single blood spill will make it dirty every time. Making it slightly bigger will increase resistance against filth.

Note that floor below a door doesn't count for Cleanliness, so you don't need to place sterile tiles there. However, filth on a door does count, and colonists stepping from dirt to a paved tile will accumulate filth.

With straw matting

Combining sterile tiles with straw matting can increase the cleanliness of a room, while decreasing the amount of filth. Put sterile tile under objects that won't be walked over, such as beds, tables, and shelves, and put straw matting elsewhere. Flower pots or sculptures will offset the beauty from both tiles

-Sterile tiles decrease the probability of [[infection]] in a [[Room roles|hospital]] and the probability of [[food poisoning]] in a [[Room roles|kitchen]]. Since [[Research]] is also affected by [[Room_stats#Cleanliness|room cleanliness]], research will gain a slight bonus if done in a room with sterile tile.

+Cleanliness will also increase room impressiveness. However, using [[sculptures]] with [[concrete]], [[paved tile]]s, or [[steel tile]]s is typically more efficient. Sculptures also increase the [[Beauty]] need, which by itself will make colonists happy. Concrete and paved tiles have a clean time of 80%, and steel tiles match the sterile tiles' 60% cleaning.
-Combining sterile tiles with [[straw matting]] can increase the cleanliness of a room while decreasing accumulation of filth. Just put sterile tile under objects which can't be walked over, such as beds, tables, and shelves, while leaving the rest of the room with straw matting. The only room that should be all sterile is your triage room, right near the killbox. Hospitals can combine steel tile with straw matting. Straw matting can be used for most of the walkways, just put 3 tile wide stretches every once in a while of non-flammable tiles. Straw matting is 93% walk speed with 1/20th the filth accumulation. If you put a potted plant(daylily-18beauty) every 6 tiles for 3 width walkways, the beauty will be offset.
-For hospitals: If you can afford to clean the hospital before healing/operating on a patient you might only need to worry about -20 debuff for cleanliness as you will only have to worry about the new blood spilling from the patient in bed (bleeds slower). The cheapest room size to maintain cleanliness for triage is 4x5, but has to be cleaned everytime. The most effective is 6x5.
