I just had a white tile floor - the classic hexagons, installed in my bathroom. Lovely pattern, but when the white grout was applied, the pattern disappeared. The floor now looks too white and boring.

How can I darken the grout? Is it better to do it now as the grout is still curing?

The tiles are about 2" hexagons. I thought of using diluted soy or coffee or even ink.

Any suggestions?

Hi Nora,

There's no easy way to say this but the best solution is to replace with a grout color you do like. Staining grout will most likely leave the finished product color uneven. Some grouts have sealers already in them so you could have mixed results too. It's even possible that you may stain the tiles themselves if using ink.

It's a lot of work to remove and replace grout with the smaller size tile you have, but at the end of the day, I think you'll be more pleased with the finished result.

Trusting this helps provide a solution for you.

Hi there,

I have seen some products in the past that state they will stain your grout to a color you choose.(Polyblend one company product) an actual grout staining kit. Only issue I can see is if it has been sealed it might be hard to get a nice uniform color.

Just do some searching and see.. obviously easier to go from light to dark in the staining process.

Best of luck!

You will have to find out what sort of grout was used on your job. There are grout stains available that will permanently change the color of the grout, but you will have to know if it is cementitious or epoxy grout so that you can purchase a compatible product.

You can do this job yourself, it is extremely easy. Check with a local flooring supplier or even a retail outlet.

We have changed white grout to black using this method, and the product that we used is from a company called Aquamix, although there are many manufacturers making them now. Mapei has one, Grout dye company has one, and in your area you should have no problem at all finding this.

I don`t think I would bother with an organic method like tea or coffee as the grouts that we have today contain so many plastics that you will surely find that the grout will appear blotchy on completion.

Good luck with your project.

Oh, if you don`t feel comfortable taking on this sort of work, a tile installation contractor will charge you to do it.
