The cost to regrout tiles is $5 to $25 per square foot and varies depending on the type of tiles being regrouted. Expect estimates in the following ranges:
Shower tiles: $10 – $25 per square foot
Wall tiles: $5 – $6 per square foot
Floor tiles: $6 – $8 per square foot
The prices above include the complete removal of old grout. Make sure these details are written in the estimate, as some contractors may not remove all the old grout and quote prices as low as $1.70 to $5 per square foot.
Grout replacement isn't difficult, but it's time-consuming. Removing the material is the most labor-intensive part of the job. Some estimates indicate it takes about four times longer to remove old grout than to apply new grout. Some DIY-ers start the process, then call a pro after realizing how long the job will take.
For DIY-ers, note that even with the best grout removal power tools, it may be impossible to completely remove all of the discolored material without incurring tile repair costs. If you’re concerned about having too much tile repair, consider hiring an experienced pro who can do the job efficiently and keep the cost to repair ceramic or porcelain tiles as low as possible.
Grout Replacement Cost Factors
When calculating the potential cost to regrout a tiled surface, consider factors like the type of grout you’re using, the condition of the existing grout, and the size of the tiles you’re working with.
Type of Grout
The average cost to regrout tile depends on the type of grout you use. Several types offer unique properties that make them more expensive than generic grout. These include antifungal grout, antibacterial grout, epoxy grout, unsanded grout, and finely sanded grout. Dry grout costs approximately $10 to $65 per 25-pound bag, while premixed grout costs around $12 to $160 per bag.
Condition and Repairs
The condition of your existing grout can impact costs, especially if repairs are needed. For example, if your current grout is degraded and moldy, moisture may have gotten through and damaged it. You’ll need to pay for water damage restoration costs before any regrouting can begin.
Size of Tile
The tile size you're using for your project will impact the amount of grout you need for the job. The smaller your tiles, the more grout lines your surface will have.
