Regrouting porcelain wall tiles in shower and bathroom

Does anyone know if regrouting glazed porcelain wall tile in the shower/bathroom wall is problematic?  Is there a risk of breakage and chipping?

Hey ginna123,

Thanks for your question and joining us here on the community.

There will be an issue of grout failure if you fail to take out the existing or damaged grout that is already there. 

Depending on the severity of the grout will determine if you can repair, replace, or simply recoat it via a grout renewal system. 

If you decide it needs to be regrouted due to damage, you'll need to remove as much of the existing damaged grout as possible via a grout saw or oscillating tool. Simply putting new grout over existing grout won't hold up and will fail within a short amount of time, not to mention it leaving a big mess.

If the grout is just dirty, ugly, or discolored from years of misuse, you can also opt for Grout Renew. It's sold at your local Home Depot's tile aisle, and is easy to use.

It's basically a high quality paint colored to match grout colors and seals the grout itself once it is dried. That can be an easier option versus full on regrouting if it is in good condition but not in appearance.

Let us know which option you choose, and if we can be of further assistance,
