Re-grouting a shower is the process of removing and replacing the old, damaged grout with new grout. Grout is the material that fills the joints between tiles, and over time it can become stained, cracked, or missing. Re-grouting a shower can improve the appearance of the shower, prevent water damage, and make it more hygienic.
There are a few different ways to re-grout a shower, but the most common method is to use a grout saw to remove the old grout and then apply new grout with a grout float. It is important to clean the tiles thoroughly before applying new grout, and to make sure that the new grout is applied evenly and smoothly.
