But typically, you will need to leave for at least 72 hours to make sure that the grout has cured properly and won't be compromised when exposed to water. But if you are using epoxy grout this only needs to be left for at least 24 hours.
All you need to do is leave the grout to dry before getting it wet. The instructions should tell you for how long. As you and others have pointed out drying and curing are separate things. While you can use the shower after the grout is dried you may need to leave it for a day or two after it's cured before sealing.
Grout that hasn't dried properly or gets wet before it cures may also allow water to seep into the gaps and behind tiles. Plus, if grout isn't given sufficient time to cure before sealing it, it may flake or peel.
Grout is used to fill the gaps between walls, usually tiles, so that they stick together. For grout to work its magic, it should be left to dry for a reasonable amount of time; otherwise, all your efforts will be ruined. On average, grout takes around 24-72 hours to dry.
He points out that he sees a “whitish” color on the edges of the grout. That is another very important clue. Grout almost always appears darker when wet than when dry. New grout can take 24 or even 48 hours before it dries completely.
Once the grout has started to harden (20 to 30 minutes), begin sponging. Don't use just any sponge, especially one from the kitchen; choose a “hydrophilic” sponge. Make sure the sponge is damp, not wet, and sweep diagonally across the face of the tile and wipe the grout off the tile surface.
Your grout to become water-damaged, subflooring to become water-logged, and possibly harbor mold, as well as tile breaking loose. Water damage affecting tile and grout can cause discoloration, stains, mold growth, and more.
We recommend waiting for at least 48 hours after installing a grout before you apply a sealer. Older grout should be cleaned thoroughly before being left to dry. Make sure to protect grout from spills and stains during this time, otherwise you'll be sealing in the dirt instead of keeping it out!

Highly caustic or acidic cleaners, like bleach or vinegar, will corrode and slowly destroy grout and tile finishes.
The answer is, no, grout is not waterproof. However, it is water resistant. That means it will need to be submerged in water for a very long time before the liquid starts seeping through its material. Read on to find out more about grout's characteristics in relation to water.
No matter how good you are with a sponge, once everything is dry (usually overnight) there will still be a grout haze on the floor. You'll be tempted to use a wet cloth to wipe it off, but that will put you in a vicious grout-wiping cycle. A better idea is to use a dry towel to rub off any haze.
Floor grout, in general, usually dries completely after 24 hours, although humidity and other factors can extend this drying time to 48+ hours. Grout haze can sometimes be simply buffed out with a dry towel or cheesecloth, if done immediately within the first 48 hours.
It is important to wait until the grout has set in before wiping the tiles clean, as premature wiping can result in gouges. However, don't wait too long, or the grout will dry onto the tiles, potentially causing irreversible damage.

The inhabitants should then wait an additional 24 to 72 hours after the tiles are grouted before walking on them.
