Want to change the look of your bathroom? Don't want to spend a fortune? First, start by evaluating the floor.
If you have tile, what do you see? Dirty, dingy grout? Loose grout? That's such an easy fix! Start by cleaning the floor with a ph balanced cleaner such as Simple Green.
If you have loose grout, remove the sections of grout that are no longer bonded to the floor or tile.
Then you can fill it in with any light or neutral color grout-don't worry, it's not going to stay this way:).
Allow to cure overnight.
Make sure that you use the same type of grout that was originally used.
For grout lines less than 1/8 make sure your grout is unsanded-grout lines over 1/8 should be sanded.
Most home improvement box stores will carry a grout colorant or tint.
This is the most cost effective and simple way to change the look of the grout.
The colorant is "painted" on with a sponge paint stick.
Sanded grouts will absorb the tint quickly because of its porous nature, so you may need to apply a second coat the following day to achieve a consistent color.
Most ceramic and porcelain tiles are finished/sealed so the grout tint will not adhere to the tile itself, so don't worry about staying between the lines as most all grout tints are an acrylic base with warm water and soap clean up.
You will want to make sure that you have given the tint ample time to cure before clean up.
Most grout tints come with at least a 15 year warranty when cleaned the recommended way.
This method is not recommended for natural stone that is not sealed.
Stone is porous and will accept the tint very quickly.
If you are not sure if your stone is sealed or not, find an area not visible from a standing position and try a small area first.
If the tint wipes off of the stone, you are okay.
If not, apply a stone sealer before the tint process.
Changing your grout color is a simple, cost effective way to spruce up your bathroom floor.
