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 important for a few different types of rooms and buildings. Having a high base cleanliness from sterile tiles means a greater margin before filth accumulation matters and, in some cases, provides additional bonuses. The following are affected:

Hospitals: In a full room of sterile tiles, surgery success is increased by roughly ×1.05 from 0 cleanliness, while tend quality also increases.^{[How much?]} Infection chance per wound is also multiplied by x30%, compared to x50% at 0 cleanliness. While maximum surgery success chance is possible without sterile tile, the extra cleanliness provides a buffer when patients start bleeding all over the floor and the extra tend quality can all save a pawn's life. Sterile tiles should be installed when can afford it.
Laboratories: Research is accelerated in a clean room, up to +9% in a sterile room, from 0 cleanliness.
Kitchens: Cooking in a dirty room has a chance to give food poisoning. However, the cleanliness need only be -2.0 or above minimum chance. Therefore, even dirt floor is sufficiently clean so long as filth is removed. Straw matting is as well and prevents 95% of accumulated dirt and trash, which usually makes up for the loss of cleanliness buffer over sterile tile.
Biosculpter pods: Pods run up to +15% faster in a sterile room. As room space doesn't matter, you can make a 2x3 room with just the pod inside it, which is easily affordable.

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.

In general, sterile tiles aren't an immediate priority to research. Get power, weapons, and enough defenses first so that your colony doesn't fall apart. Then you should get sterile tiles to help save lives. The research is also required for hospital beds, which provide a further boost to medical success.

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, you may want 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. You can increase the size, which increases room Impressiveness, as you can afford it.

Note that floor under a door doesn't count for Cleanliness, so you don't need to place sterile tiles on a doorway. 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. Straw matting under the door is ideal as it won't reduce the cleanliness of the room but will prevent filth on that spot that can.
