Sterile tile usage

[Hanuman]

I was wondering, for sterile tiles to 1) help in surgery rooms 2) speed up research
does the whole room need to be tiled in sterile (expensive, 12 silver each) tiles? or just under the table/bed and around it?

The whole room for maximum effect.

Also remember some furniture/ workplaces (ie the butchers s table and the crematorium) give a dirtyness penalty for said room so watch out for that.

It is the overall room stat that affects things. So the location (putting them directly under the table) doesn't really matter.

The effect is based on the averages of the tiles in the room. So if you want to save resources you can use smaller rooms. A 3x3 room for surgery with 9 sterile tiles is just as effective as a 10x10 room with 100 sterile tiles, but if you just put a 3x3 of sterile tiles in that 10x10 room it will do very little.

The downside to smaller rooms is that any filth that gets in the room (blood, trash, dirt) will also have a much larger impact on the average cleanliness, so you have to make sure they're spotless before you use them if you want the full effect.

The easy way to check is to click on a piece of furniture to see the room stats. If your room is Clean, no bonus. If it's Sterile, bonus. It's that simple.

#1 Absolutely. A "sterile" room gets a bonus in medical outcomes and research.
#2 Depending on your room size and how clean you keep it, you may not need to cover the entire area to get to "sterile".

Other tiles (steal silver...) the same effect, but to a lesser amount.

Or if you are more of a numbers type you can look a this:

One thing that a lot of people seem to get wrong is to put the butchery tables near to their cooking tables. Like, in the same room. Sure, it speeds up the whole "cut up animals and then cook them" deal, but it also spills blood and guts everywhere and increases the chance of food poisoning. Cut stuff up in a different room. One that doesn't need to be clean in the slightest.

I always put my butcher tables outside where the blood doesn't matter. Who cares if some leather gets left on the ground for a few hours?

The blood doesn't really matter inside either, if you give it its own room. Yeah, it'll be a gore-smeared abattoir until you get some full-time janitors but oh well. It's faster inside, where it doesn't have the outside penalty and is temperature-controlled.

I just pop mine in my general stockpile with all the leathers.

[Midas]

A butcher table is good suited in a room with straw floor, cause it has a max filth rate

[NisseDood]

When it comes to filth I reccoment common sense mod.
Makes colonists clean up the work area before doing the job.

[Oobaneko]

I need to make 40 biosculpt pods for my colonists. Every reverse aging takes 5 days in clean room. In sterile it takes 4.5 days.

You don't get food poisoning before room's cleanliness drops below -2. That means that even 5x5 room with dirt floor and a butcher table is safe to cook. Floored rooms are pretty much impervious to food poisoning unless something goes horribly wrong in your colony.

Like, for instance, using a dirt floor and putting the butcher's table in the same room, splattering everything with gore.
