How Often to Regrout Shower Tile

One of the most popular questions homeowners ask is how often they need to regrout their shower tile. The answer depends on several factors, including where you live and what type of grout was used in your shower when it was first installed. If you are unsure, call a professional for an inspection or consult with your local building department. 

This blog post will cover some general guidelines about how often to regrout shower tile based on different situations. There are many reasons why one might need to regrout their tiles but before we get into those, let’s start by looking at the basics.

How Often to Regrout Shower Tile

Five Reasons Why Should You Regrout Shower Tile?

1. To Prevent Mold:

Mold thrives in damp, dark places, something often seen in grout lines between tiles. Many mold-killing products are available but could pose health risks if ingested or inhaled. The best way to avoid this problem is to prevent it from starting by regrouting shower tile before the dirt becomes entrenched.

2. To Fix Broken Tiles:

Loose, broken, or dirty tiles are not only unsightly but dangerous. Loose tiles can fall off and cause someone to slip and fall. Dirty shower tile collects germs that invite disease-causing bacteria when stepped on sitting in the dirt for days. Treat it early before someone gets hurt.

3. To Improve Aesthetics:

Mold, algae, dirt, and mildew are unattractive. Even if you grout the shower tile every year to keep it free of dirt, these contaminants can find their way back into the grout lines in between tiles. Once there, they will be much harder to remove all by yourself with cleaners that you’ve got lying around your home.

4. To Save Money:

Even if you do manage to avoid the pitfalls of mold, algae, dirt, and mildew, it is still an excellent idea to regrout shower tile because it will make the tiles last longer. Since grout lines are spaces between tiles,

they are especially vulnerable to damage from foot traffic and other wear and tear. Sealing the tiles will help them remain free from dirt and grime and water damage that erodes at grout over time.

5. To Improve Overall Bathroom Appearance:

If you take a close look at your shower tile, you will probably notice some staining or discoloration on the tile itself. This is not dirt on the tile but minerals from water seeping through the grout and depositing minerals on the tiles themselves.

Sealing your shower tile will prevent this problem and give you a more uniform appearance all around, including inside showers where most people will see it if they enter your bathroom.

6 Factors That Determine How Often to Regrout Shower Tile

Below we have mentioned some factors that determine how often to regrout shower tile.

1. Type of Tile Used:

The type of tile used will determine how often to regrout shower tile. Each manufacturer provides a coating on the tiles that determines the life and performance of the tile. This coating affects how clean and smooth your grout lines stay and how easy they are to keep clean.

For example, ceramic tiles often come with a glaze finish that will resist water and stains better than porcelain or natural stones. However, because of this coating, you have to maintain the tile using special care.  

2. Number of People Using the Shower:

The more people in your house who use the shower, the less chance there is for dirt, body oils, and soap to build upon the tiles. If more than one person uses the shower daily, you should regularly use tile maintenance services to clean your tile.  

3. Use of Shampoo Bottles:

Shampoo bottles can leak overtime under the kitchen or bathroom sink. The leaked shampoo often contains chemicals that will stain the grout lines between your tiles. This usually happens when homeowners leave these bottles under their kitchen or bathroom sinks for long periods without cleaning them properly.  

4. Type of Flooring in the Room:

There are several types of flooring that you can use in your shower room, including linoleum, carpet, the tile. For this reason, you will need to regrout more often in high-traffic areas like the shower floor or directly under the showerhead. In addition, when you share your shower with others, it is best to clean it daily and invest in special cleaners designed for tiles like TSP.  

5. Type of Grout Used in the Shower:

Other grouts have different lifespans, so you should choose carefully when selecting your grout color and texture for your shower. The most common grouts are sanded grouts that are often available in gray, white, blue, black, cream, brown, and beige.

These grouts often have a smooth, finished texture that will not absorb water quickly, so it is best to use them in showers that are used less frequently.

Unglazed tiles contain some sand particles that remain on the tile’s surface and unsanded grout, which contains more sand particles. Unglazed tiles are often small in size, making them difficult to clean.

Unsanded grouts are porous and absorb water quickly because they have more sand particles. Still, when sealed with grout sealant, these types of grout can be effective when used in higher traffic areas like the shower floor or directly under the showerhead.  

6. Design of the Bathroom:

If you have a bathroom flooded with natural or artificial light, it makes your tile sparkle. However, if you have any tiles located in dark areas, they will quickly grow dirty as time passes. In this case, you should contact professional cleaners to clean and regrout these tiles regularly.

1. There are various products available for regrouting shower tile, so the best way to find the right product is to ask at your local home improvement store.

2. The process of grout removal can be complex because it is time-consuming and messy. The grout needs to be scraped out by hand or with a special tool.

3. The tile or grout should be wet before regrouting, so the new grout will stick to it correctly. Allow your shower to remain unused for 24 hours after regrouting. This will allow time for the shower walls to dry completely before using again.

5. A primer should be used before regrouting, especially on very porous tile or grout.
