The Easiest $10 Way to Refresh Old Grout Without Regrouting Your Tile
HOME | CLEANING | DIY | BATHROOM
Sometimes a tiny home project makes a surprisingly huge difference.
One of my favorite inexpensive bathroom upgrades is simply refreshing the grout lines with a grout pen.
I have used these grout pens in several different colors around our house, and they work so well. When grout gets old, stained, discolored, or just no longer coordinates well with the tile, the entire floor can start looking dated—even when the tile itself is perfectly fine.
Painting the grout gives you that satisfying “something looks SO much better in here” feeling without ripping anything out.
And compared with actually removing and replacing grout? This project is incredibly simple.

My Favorite Grout Pen
The one I have used is the Grout Pen Beige Tile Paint Marker, and I have actually purchased grout pens in several different colors depending on the room and tile.

The beige color was especially helpful in this bathroom because the floor already has warm cream and beige tones.
Instead of trying to make the grout bright white—which could actually make the floor look too harsh—the beige blends beautifully with the tile.
Look at the Difference Fresh Grout Lines Make

One of the things I love about this project is that you don’t necessarily notice the grout itself when you’re finished.
You just notice that the entire bathroom looks better.
The tile suddenly looks cleaner.
The floor looks more uniform.
And the whole room feels a little more polished.
It is one of those inexpensive home projects where the visual payoff is much bigger than the amount of money you spend.
You Don’t Necessarily Need New Tile
It is so easy to look at an older bathroom floor and immediately think:
We need to replace this tile.
But sometimes the tile isn’t actually the problem.
The grout is.
Grout naturally changes color over time. Dirt settles into it, cleaning products can discolor it, and certain areas may become darker than others simply because of foot traffic and everyday life.
When all of those grout lines become inconsistent, your eye starts seeing the entire floor as old or dirty.
Giving the grout one consistent color can completely change that.
Grout Pens Are Also Great When Your Grout Won’t Come Clean
There is a point where cleaning grout becomes an exercise in frustration.
You scrub it.
You try a different cleaner.
You use another brush.
You bleach it.
You scrub it again.
And some of those dark or discolored areas simply do not disappear.
At that point, I would much rather recolor the grout than spend hours scrubbing the same lines.
A grout pen essentially gives the grout a fresh cosmetic finish so you aren’t constantly fighting stains that have worked their way deep into the grout.
Choosing the Right Grout Pen Color
I have these in several colors because the right grout color really depends on the tile.
For a light floor like ours, beige works beautifully because it complements the warm stone coloring.
You can also find grout pens in shades like white, cream, gray, and darker tones.
My biggest advice is don’t automatically choose bright white grout just because your tile is light.
Look closely at the undertones in the tile.
If you have:
- Warm ivory, tan or cream tile → try beige or cream grout
- Cool white or marble-look tile → white or light gray may look better
- Gray tile → gray grout often creates a more seamless finish
- Dark tile → a darker grout can sometimes look much more sophisticated
You want the grout to look like it belongs with the floor rather than drawing attention to every single tile line.
How I Use a Grout Pen
This really is a very approachable DIY.
Start by giving the floor and grout a good cleaning. You don’t want to seal dirt, dust or residue underneath the grout color.
Then let everything dry completely.
Shake and prepare the grout pen according to the package instructions and begin working along the existing grout lines.
I find it easier to work in smaller sections instead of trying to tackle an entire bathroom at once.
If a little grout paint gets onto the tile, wipe it away before it dries.
Then simply keep working your way across the floor.

Take Your Time Around the Edges
The middle of the floor is usually easy.
The areas around the toilet, vanity and baseboards take a little more patience.
Those are the spots where I slow down because you want the finished lines to look intentional.
It doesn’t need to be absolutely perfect. Once the entire floor is finished, you really don’t notice every tiny variation.
You see the overall effect.
This Is One of My Favorite Budget Bathroom Updates
There are so many bathroom projects that quickly turn into thousands of dollars.
New flooring.
New vanity.
New fixtures.
New tile.
New everything.
This isn’t one of them.
Sometimes you can make an older bathroom look dramatically better simply by working with what you already have.
Fresh paint, clean trim, refreshed caulk and newly colored grout can completely change the feeling of a bathroom without a renovation.
I Especially Love This Trick in Older Homes
If you have older stone-look tile, ceramic tile or builder-grade flooring that isn’t necessarily what you would choose today, try changing the grout before deciding you hate the floor.
You might be surprised.
Once all those grout lines are consistent and clean-looking, the tile itself may suddenly feel much more neutral and usable.
That is exactly why I like inexpensive projects like this so much.
Not everything has to be ripped out.
Sometimes it just needs a refresh.
The Bathroom Looks So Much Cleaner Now

Every time I look at this bathroom now, I notice the difference.
The floor feels cleaner.
The tile looks better.
And the grout isn’t distracting me anymore.
That alone makes this little DIY worth doing.
Would I Use a Grout Pen Again?
Absolutely.
I already have.
I’ve purchased these in multiple colors because they are such an easy thing to keep around for little home updates.
If your grout is structurally damaged, crumbling or coming out, that is obviously a different situation and may require actual grout repair.
But if your grout is basically fine and you just don’t like the way it looks, a grout pen can be a fantastic inexpensive fix.

I used the beige shade for this particular bathroom, but I own several colors and choose whichever one works best with the tile I’m refreshing.
Before You Replace Your Bathroom Floor…
Try the grout.
Seriously.
It’s one of the easiest places to start.
For the price of a grout pen and a little bit of time, you may discover that you don’t actually hate your tile nearly as much as you thought you did.
Sometimes the floor doesn’t need replacing.
It just needs its grout back.
