How do I keep grout clean?
The best thing you can do is get something such a toothbrush. A steel brush isn't ideal, because you could wear out the grout or run it down or scratch the tile. You can also use a light bleach to keep it clean and spray on grout sealer. Make sure to keep your grout dry, because it's a breeding ground for bacteria and follow manufacturer recommendations.

How long will my bathroom remodel take?
It depends on what's being done. If something is being done with tile, it could take 6-7 days. If a three-panel system is being put in, the work 3-5 days.
Should I use tile or acrylic in my tub surround?
It depends. Tile has a lot of variations and you have lots of pattern and design options. Tile is generally more expensive than acrylic, because it's a lot more work to set every tile. Tile provides a richer, classier look. However, there's more maintenance after tile is installed. If you have natural stone you need to seal the tile ideally once or twice a year, but you should check with the manufacturer's guidelines. Tile has grout, which needs to be sealed and stained. You don't know when it's going to happen, but you'll have issues with grout, such as mold or hard water stains. Most of them will last a couple of years without any issues.
Acrylic pieces are nice, because there are generally only a couple pieces, so you save on labor costs. Acrylic is glued or fastened to the wall. It also cleans easier, because all you have to do is wipe it down. It's not uncommon for white acrylic to yellow from hard water or mineral rich water. However, acrylic doesn't always look as rich or fancy as tile. It depends on the quality of acrylic that you use. Curved acrylic inserts even when installed properly don't have complete contact with the wall, which creates an air void. When you bump an air void, a hallow sound is created, similar to what it sounds like when you step into a port-a-potty.
