What to Consider When Choosing the Best Grout Sealers for Shower
As mentioned above, to find the best grout sealer for shower, you should evaluate some factors to choose one that suits your needs. You could either assess your situation independently or acquire expert help to understand which grout sealer will work best for you. If you choose to go the first route, there are several factors to take into account, and below, I have explained the importance of each of them:
One of the main reasons we seal grout is to prevent water damage which will later give way to mold and mildew to grow. Hence, first and foremost, you must ensure that the grout sealer you choose will be waterproof and guarantee resistance against any water damage that might ensue.
A good, waterproof sealer will prevent mold and mildew, which are detrimental to our health and, specifically, our respiratory system. Moreover, such a sealer will not allow water to penetrate the grout, which can then cause cracks in the grout and make the whole tile project look unseemly. This factor is especially important when sealing shower grout, as showers are moist areas that can cause damage quickly.
Another factor to consider is the application type. If you are unfamiliar with grout sealers, you should know they come in various shapes, forms, and application types. Some grout sealers are spray-on, others come in tubes, and some come in large containers
. Depending on the “packaging,” you apply them differently. For example, spray-on sealers, as the name suggests, are carefully sprayed in layers on top of the grout. Tube sealers are another easy choice to apply, as you just need to squeeze the product on the grout. Containers, on the other hand, will need an applicator, such as a brush or sponge, to coat the grout. Which product you choose is entirely up to you, so pick a sealer that makes the job easier for you!
Types of Grout Sealer
A crucial thing to take into account is the type of sealer you will use. Grout sealers mainly fall under two options: penetrating and non-penetrating sealers.
Penetrating sealers are regarded as the safest option. If you are wondering what is the best sealer for shower grout, look no further than products of this type. Penetrative grout sealers are so awesome because they will settle into the pores of your grout and form a protective layer from deep inside. They are the best tile and grout sealer for shower options, as the protective coat formed in and on top of the grout will keep water from penetrating the pores, thus, preventing mold and mildew growth. Usually, penetrative grout sealers will last anywhere from 3 to 5 years.
If you think that its benefits stop there, think again! These sealers come in both color and colorless versions. If the grout in your tile installation has suffered from discoloration or is stained from oil or food spillage, I would highly recommend going for a color version, as it will aid in restoring your grout’s color while also protecting it from more damage. Likewise, if you want to change the grout’s color to something else, such options can be handy! However, if you want to maintain the grout’s color, go for a colorless penetrative sealer which will not change its color, but enhance it instead.
Non-penetrative sealers are the second option. Although penetrating grout sealers have many benefits, non-penetrating ones do not fall behind. They offer more basic protection by forming a layer on top of the grout lines; however, if the sealer you choose is waterproof, it will be just as safe as penetrating sealers. I find the coat these sealers create quite a beautiful addition to some of my tile installations as they can make the surface covered glow.
Unlike the ones above, these sealants must be reapplied every two years maximum. You can do a simple water test to check whether its protective abilities are wearing off. Speaking of water, a non-penetrating sealer is not the best grout sealer for bathroom shower, as it is not as durable as penetrating sealants.
Another thing to bear in mind when it comes to non-penetrating grout sealers is that they do not work well on glazed tiles, which will cause the layer you applied to start to tear away. These sealers are best used with natural stone or unglazed type of tiles.
Types of Grout
Just like I advised you to keep in mind the sealer types, you should also consider the type of grout used in your tile project, as some grout types do not do well with certain sealer types or do not require sealing at all.
An example of the last option is epoxy grout. If the grout lines in your tile project are filled with epoxy grout, you will not need a sealer, as it is non-porous and highly durable.
The rule of thumb when choosing the proper sealer for your grout type is knowing if the grout you have used is porous. Less porous grout types can fare well even with non-penetrating grout sealers, as they are more durable and less prone to water damage. Porous grout can easily absorb water; hence, it needs maximum protection, which penetrating sealers could offer.
Many people prefer using solvent-based formulas as they can penetrate the grout more deeply and believe they offer more protection when compared to water-based formulas. Although this choice is mostly up to preference, it is important to note that solvent-based sealers contain harmful chemicals for the environment and humans alike. These sealers contain VOCs (short for volatile organic compounds ) that can release toxic fumes into the air during and after application.
The inhalation of these fumes can cause respiratory problems, headaches, dizziness, and even nausea. Additionally, the use of solvent-based sealers can have negative effects on the environment. The VOCs in these sealers can contribute to air pollution, and the disposal of leftover sealer and cleaning materials can contaminate soil and waterways.
Fortunately, there are safer alternatives to solvent-based grout sealers. Water-based sealers are another popular choice as they contain fewer VOCs and are generally safer for people and the environment. It is crucial to always read and follow the instructions on the product label, wear protective gear such as gloves and a mask during the application, and properly dispose of any leftover materials.
Choosing the right grout sealer for the surfaces you will be sealing is crucial for achieving the best results and protecting your surfaces. Firstly, you should consider the location of the surfaces being sealed. High-traffic areas such as hallways and entryways may require a more durable sealer that can withstand wear and tear, while areas prone to moisture, such as bathrooms and kitchens, may require a sealer that is resistant to water damage.
Additionally, some formulas may or may not work with your tile types, so you should look for a sealer that will not damage your tiles through a chemical reaction by eroding them.
If you plan on sealing the grout on kitchen counters or places near food, carefully check the products’ labels to see if they are safe for food contact.
Durability is an essential aspect to consider when choosing a grout sealer for your shower because it determines how long the sealer will provide protection against water damage, mold growth, and stains. Showers are exposed to constant moisture, and the grout is a prime target for water damage, leading to mold growth and weakening the grout’s structural integrity. A durable sealer will create a barrier that can withstand moisture for an extended period, providing long-lasting protection for your grout.
Choosing a durable sealer will save you time and money in the long run by reducing the need for frequent reapplication and preventing costly repairs due to water damage. Additionally, a durable sealer will maintain the appearance of your shower, preventing unsightly stains and discoloration. Therefore, when selecting a grout sealer for your shower, it’s crucial to consider the durability of the sealer to ensure that it can withstand the harsh environment of your shower and provide long-lasting protection.
As a last aspect in the list, we have price. This one is an important consideration when choosing a grout sealer, as it can vary greatly depending on the type and quality of the sealer. However, it’s essential to strike a balance between price and quality, as choosing a cheaper, low-quality sealer may cost you more in the long run.
Cheaper sealers may not provide adequate protection and may need to be reapplied more frequently, leading to additional time and money spent on maintenance. Conversely, a high-quality sealer may have a higher upfront cost but can provide longer-lasting protection and ultimately save you money in the long run.
Additionally, the project’s size and complexity should also be taken into account when considering the price. Larger projects may require more sealant and, therefore, a larger budget, while smaller projects may be more cost-effective with a cheaper, smaller-sized sealer.

It stands to reason that many first-time buyers may not be familiar with the products and how to use them properly. In this section, we answer some of the most common questions people ask when looking for the best grout sealer for shower.
Q. Should you seal your grout in the shower?
Yes, it is highly recommended that you seal your grout in the shower. Doing so will help protect your tile and grout from water damage and staining. Sealing your grout will create a barrier between the tile and the porous surface of the grout, which helps to prevent moisture from penetrating and damaging both surfaces. This also prevents mold growth since moisture cannot get absorbed into the grout lines.
Q. How do I make my shower grout waterproof?
Shower grout is a porous surface, meaning it absorbs water and can easily become damaged over time. This can result in leaks that are difficult to repair. To make your shower grout waterproof, you need to seal the grout lines from moisture and prevent any further damage from occurring.
The first step to making your shower grout waterproof is cleaning it thoroughly. Use an anti-bacterial cleaner or a mild soap solution to clean off any built-up grimy residue on the grout lines. Scrub away as much of this dirt and debris as possible with a scrub brush or power washer before rinsing with warm water and drying completely with towels or a hairdryer.
Once the area is cleaned and dry, you will need to apply a sealant specifically designed for use on showers that has been certified by NSF International (National Sanitation Foundation). Make sure the instructions on the bottle are followed precisely during application, especially if there are multiple coats needed for full protection. Give enough time between each coat according to product instructions so that everything sets correctly before proceeding.
Q. What is the best way to protect shower grout?
When it comes to protecting shower grout, the best way by far is through the careful application of a clear silicone sealer. This sealant creates an effective barrier against moisture, mold, and mildew that may otherwise damage your shower grout. It’s not only a great solution for preventing water damage but also helps keep your bathroom looking brighter and cleaner in the long term.
