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.

Sterile tiles should be installed when you can afford it. |

However, the cleanliness only needs to be at -2.0 or higher to avoid the higher chance. Therefore, even [[Terrain|dirt]] floor is sufficiently clean so long as filth is removed. [[Straw matting]] is naturally sufficient as well, and prevents 95% of accumulated dirt and trash, which usually makes up for the loss of cleanliness buffer over sterile tile. If your kitchen is sufficiently small, sterile tiles will generally save time in cleaning, but for larger kitchens, straw matting will generally save more time. |

− | + | Cleanliness will also increase room impressiveness, however, sterile tiles also negatively impact beauty, which ''decreases'' impressiveness (not to mention also impacting the beauty need!), which makes sterile tiles a very inefficient method for increasing impressiveness. If your only goal is to increase the impressiveness of a room, you should instead use [[steel tile]]s, which provide a lesser cleanliness benefit but do not impact beauty; [[carpet]]s, which provide a substantial amount of beauty, but no cleanliness boost (and, in fact, take substantially longer to clean); or [[Stone tile]]s, which provide less beauty than carpets and do not provide a cleanliness boost, but take far less time to clean. Even the humble [[Wood floor]] can be preferable for impressiveness, so long as you keep it clean. [[Sculptures]] are also vastly more resource efficient at increasing impressiveness than sterile tiles are, providing a 1:1 steel to beauty ratio for a normal-quality sculpture. In short, don't use sterile tiles for impressiveness alone, only use them when the cleanliness itself is important. | |

− | [[Steel tile]]s only | + | [[Steel tile]]s provide only a third of the cleanliness boost (0.2 versus 0.6), and cost 4 more steel per tile (7 versus 3) than sterile tiles, but are also overall cheaper (value of 16 versus 24), do not require silver to create, do not impact beauty (0 versus -1) and take substantially less research (Steel tiles only require smithing, which is a vital research project anyway, whereas sterile tiles require both the electricity and sterile materials research projects). Both provide the same cleaning speed boost - taking only 60% of the time to clean that wood flooring does. If the player is short in silver and high in steel, or is too early in the research tree to build sterile tiles, this is the best alternative to sterile tiles, and may even be preferable in some situations (e.g. the kitchen, since you only need to be above -2.0 cleanliness). |
+ | |||
+ | [[Gold tile]]s and [[Silver tile]]s generally provide the same benefits as steel tile, but provide a large amount of beauty (+11 and +4, respectively) and are '''vastly''' more expensive than any other flooring in the game. Technically these can work in situations where the player has a vast amount of resources but hasn't researched sterile tile, and is technically the "ideal" flooring for the kitchen (setting aside [[Style]] bonuses from other floors) as, as mentioned above, kitchens only need to be above -2.0 cleanliness, and the immense beauty is great for someone who sits next to it all day long, but this is an absurd waste of resources. | ||
− | [[ | + | [[Paved tile]]s don't increase cleanliness and take a bit longer to clean than sterile tiles (80% versus 60% cleaning time, which is still an improvement over the norm), but take only 2 steel per tile, and, like steel tiles, have no beauty impact. These combine to make paved tile a fine early-game alternative to sterile tiles. |
− | [[ | + | [[Concrete]] is almost strictly inferior to sterile tiles, providing no cleanliness boost, the same -1 beauty penalty, and taking longer to clean (80% versus 60%). However, they're incredibly cheap, costing a mere 1 steel per tile. However, as it does not give a yield on deconstruct, it's generally a poor idea to place concrete in rooms where you plan to use sterile tile in the future. Paved tile deconstructs for 1 steel (providing the same net cost when upgrading) and has no beauty penalty. In situations where materials is scarce, though, concrete is the best option available. |
