How To Regrout Bathroom Tiles

Regrouting bathroom tiles is easily one of the best ways to rejuvenate your bathroom. A good regrouting job can make your bathroom tile look brand new. It is the best way to set off the look of beautiful tiling. The basic process for regrouting bathroom tile is to power grind the old grout and replace with new grout. This is a process that virtually any homeowner can do. Rejuvenation of a shower with new grout can turn an unattractive, mouldy shower into what looks like a brand new bathroom.

Grout that’s cracked, stained, and coming out in pieces not only looks terrible, it can cause problems beyond just the cosmetic ones. If water gets behind the tile, you could be starting a thriving mould and mildew colony that could be hard to eradicate.

If it’s time to regrout bathroom tiles, you’ll need to choose the proper grout for the job. If the bathroom tiles are spaced more than one-eighth of an inch apart or less, you should use un-sanded grout. Since it doesn’t have sand, it will flow better into this narrow space. You also don’t need the tensile strength with these small grooves as you would fill larger gaps.

If you have marble bathroom tiles, do not use sanded grout, because it will scratch the marble, and those scratches will be permanent. Usually, however, marble bathroom tile is installed with a gap of less than one-eighth of an inch anyway, so chances are you wouldn’t choose sanded grout in the first place.


The regrouting bathroom tiles process involves getting rid of the old grout and replacing it with new grout. Getting the old grout out usually involves the use of a power grinder, though there are other methods. There are also several types of caulk and methods for applying it. Some caulk can take care of minor repairs when applied properly.

When you regrout your bathroom tile, the first step is to clean it as best you can and get rid of any loose grout. Grout mixtures will have instructions on the package, and you should follow these carefully. You apply the new grout with a grout trowel, making circular motions while holding your trowel at about a 45 degree angle. You should be using a little pressure so as to remove excess grout as you apply it. Once you get the hang of it, it will go faster.

Once you’ve done this, use a small amount of water and a regular sponge and sponge off the tile surfaces where you’ve regrouted. You may have to do this two or three times, but finally, you’ll end up with a fine film that can be mopped away.

A good regrouting bathroom tiles job can make the difference between an unattractive bath or shower repair and an attractive one. The bathroom tile itself is easy to clean, so it’s the condition of the grout that tells the tale of how well repaired a given bath or shower is. Of course, the new grout will eventually need to be cleaned, but with grout, you have one of those “ounce of prevention is worth a pound of cure” situations.
