Sanded or Unsanded grout?

I did a small bathroom 5x10 and tiled the floor and shower walls. I used the exact same tiles for the floor as the shower and everything was set with 1/8" grout lines. I dont want to buy two separate types of grout as i think i can get the whole job done with one box.
As I understand the rule is: unsanded for 1/8" or less, sanded for greater than 1/8"
Can anyone attest to that?
Thank you!

I am almost done my basement, just in time for posting season

 

Pretty much.
Just make sure the mix isn't too wet and you'll be okay.

When fully cured, hit it with a grout sealer.

 

Sanded is stronger

 

Agreed... but 1/8" is pushing it for sanded. It can be a bitch to work into the gap.
Personally, I really like sanded... and it is a little more forgiving of being mixed a little too wet.

 

i too did 1/8" grout lines in my bathroom tiling, ...believe i used sanded grout w/ some kind of latex modifier additive...

 

you can use sanded, really it's up to you. i've laid thousands of square feet of tile. be cautious as to mixing up pretty close to the recommended specs as far as adding water and additives. keep in mind, the farther away you get from recommended specs the farther away from the desired color you are going to get. some of those mix in additives that are supposed to keep you from having to seal it afterwards tend to lighten up the color more. in my opinion i would use unsanded. as said before, it will be easier to work with. and then use a sealer afterwards. the spray cans are nice because of the ease. good luck
