You can run a dehumidifier, an air conditioner or an electric fan to help keep humidity levels low as the grout dries. Even a small fan might make a difference in a very humid area, but it's not going to shorten the minimum advertised drying time. Nor do you want it to, if you want your grout to last.
When you're searching for ideas on how to speed up grout drying time, lowering the room's humidity level can help. Removing any indoor plants and using a dehumidifier will decrease the moisture in the air, which can lower grout drying time.
Use an addmix not heat a fan blowing across the area will also help but curing it with heat can lead to disaster. An add mix with calcium will speed the cure time. Don't use fans. Mortar needs water to cure, and by removing the water you're left with a weaker bond.
New grout can take 24 or even 48 hours before it dries completely. It depends on the humidity and temperature in the room where the grout is installed. While grout manufacturers no doubt try to get the color stripe on the bags to be a true representation of the color of the dried grout, you can't count on that.
Typically room temperature is the ideal setting scenario, 72ºF-74°F and an relative humidity 30%-50%, whenever temperatures drop below 60°F and the relative humidity is higher than 70%—allow for extended periods of curing time.
The standard cement grout commonly found in most hardware stores and used in most residential homes takes around 48-72 hours to cure. But it is worth pointing out that you need to know how to mix grout the right way. If too much water is added it will obviously take longer to dry and won't do its job as well.

This time, make sure there is no excess grout on the tile's surface or beyond the grout line. Rinse the sponge you are using in a bucket of water and change as needed as you clean off any excess. Then leave the grout to dry overnight.
As the water is absorbed, the grout swells, fractures and falls away. In either case, water reaches the drywall behind the tiles and destroys it.
Air Flow. The chemical process of curing depends upon the mix staying hydrated. High winds and fans will strip your mortar of the moisture it needs to stay hydrated and cure properly. For interior mortar work, consider turning off fans that can impede the curing process.
Humidity That Is Too HighExcessive humidity and moisture can directly impact the curing period of the concrete within the mortar. If you reside in a tropical climate or in an area with significant humidity, Mapei will take longer to cure than the 72-hour maximum curing period suggested by most manufacturers.
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.
Recommendations on how long to wait after grouting tile to shower range, but most of the time, 48 to 72 hours later, you can step into your like-new shower. Though it may feel dry to the touch before this, it takes grout that long to actually cure.
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.
Make sure your tile surface is completely dry before you attempt to remove any haze. This typically takes about 24 hours. Consult your installation professional—or, if you DIY-ed it, your grout's packaging—for the exact amount of time. But do not wait more than 10 days to remove grout haze.
