Showers usage is common in our daily routine. Due to excessive water flow in bathrooms, it is mandatory to use the best grout for shower walls to prevent contamination of tiles. Since our bathroom walls are always in contact with water, there is a high chance of fungi and mold formation if you use wring grout for shower walls. Cement-based grout in bathrooms and shower floors can lead to fungi and mold formation since it absorbs water and moisture.

Our experience in using these tools for showers will certainly prove helpful before making a decision.

Buying Guide

The above-mentioned sections have given all information about the best tools used for grouting a shower. We have mentioned why each product has taken its place in the list we have prepared due to its extraordinary features. However, grout for shower floor doesn’t depend only on features. Wide knowledge about grout is far more important than just knowing its details. Let us concentrate on different concepts involved in grouting shower tiles. We will discuss different types of grout, the basic features to be looked for like buying etc. In the end, all questions will have answers from this buying guide.

What is Grout?

A combination of color, cement and water forms grout. This is the basic definition in layman terms. Grout is available in a liquid form or can be mixed with water to make it fluid. This mixture is used to fill gaps between tiles, flooring, walls etc. It is mostly preferred for use in bathrooms since fungi and mold may develop between tile gaps after prolonged use of water and moisture. Grouting shower areas is of major importance to keep your bathroom healthy and hygienic. Most of the grout mixtures can be readily available or can be mixed using instructions from the manufacturer.

Basic uses are around households in showers, kitchens, bathrooms and any flooring with tiles. We can use grout basically to remove stains on tiles, remove contamination by fungi or mold. Grout gives a protective covering to narrow places susceptible to contamination from excessive moisture and condensation from water usage. Tile and Grout sealer can be obtained to secure intricate spots.

Is Grout Waterproof?

The basic definition of grout is to safeguard our bathrooms from excessive exposure. Although grout works perfectly well in damp rooms of our house, sadly, it is not completely waterproof. It is mainly moisture-proof. A shower grout sealer can be used on top of grouts to make it completely waterproof. The sealer does the job of preventing water from seeping into tiles after installation. The major drawback is when we use grout made of sand.

Once it is placed between narrow spaces, it dries up. After curing, it begins to absorb water due to its sandy material. This is one of the main reasons why consumers prefer unsanded grout. Waterproof epoxy grout is another type of grout available in markets that can provide the least water absorption rate compared to other grout types, thus giving long life and durability to tiles and walls. Going for an epoxy grout for shower is much better to save money from buying external grout sealers. In addition, epoxy shower floors will be preferred majorly in swimming pools to reduce contamination from bacteria.

Benefits of Using Best Shower Tile Grout

Grouting shower tiles have become the most wanted method to take care of our bathrooms. Imagine your bathroom reeking odor due to bacteria, fungi, and mold formation after prolonged water usage. This may lead to uncomfortable bathing sessions and cause our bathrooms to be lackluster and lose a life. As already mentioned, grout is the best way to prevent our bathroom or shower places from becoming ugly.

Best tile grout has its own benefits, and they are listed below:

  • One of the first advantages that come to mind is, best grout for shower tiles keeps your bathrooms clean and fresh most of the time.
  • Using grouts with a waterproof design like epoxy grout can prolong the tile’s life. Water will not be absorbed; thus, seepage, mold or fungi formation etc., will not happen.
  • If not for waterproof grouts, we can even use a grout sealer on top of our grout to give durability.
  • Your bathroom surfaces become stain-resistant, thus giving a clean and lovely ambiance. Stains might reduce the pleasant feeling while you are taking a shower!
  • Dirt, debris and grease will not enter tiles or under. If not taken care of, this may loosen tiles from their position during the due course. Strength and rigidity are added to the tile’s life.
  • Colored grouts can enhance the look of shower areas. With other benefits, we get beauty too!

How much Grout do I need?

Grouts are available in ready mixes as well as can be mixed after purchase. Before purchasing, a common question might arise in everyone’s mind. How much grout do I need? Let’s go about answering this in detail.

Grout works by covering spaces between your tiles to give long-lasting durability. If we are considering tiles, then you have to know certain dimensions and areas of grouting location.

It is best to know the dimensions about:

  • The total area of tiles to be grouted
  • Each tile size
  • Tile thickness
  • The gap size between tiles

These are sufficient to have a successful grouting session. Grouting shower tiles can end up laborious without any pre-planning or preparation. Use the units of length as per your comfort level. It is always best to start with mm for small information like thickness or gaps size.

Let’s perform simple calculations to determine how much grout will be required:

  1. Tile width + tile height (can be derived from tile size) – Keep this as A
  2. The gap size between tiles * tile thickness – Keep this as B
  3. A * B + 1.2 (coverage ratio of most tile grouts) – Keep this as C
  4. Tile width * Tile height – Keep this as D
  5. C / D = E (this is the amount of grout we will require in meter squared units)
  6. Once E is done, we can just multiply the total area to get the exact amount of grout required.

It is always best to keep extra grout ready while grouting since spillage and wastage should also be considered.

Types of Grout

Cement Grout

One of the types of grout, though not preferred much, is the cement shower grout for sale. It works very well with most tiling materials. The major advantage of using this grout is its consistency. Much more liquid than regular cement flows easily into cracks and gaps, thus securing the tile’s life. The major disadvantage, as noted, will be its porous nature. Few undetectable points after curing might be problematic and lead to water and dirt seeping in. Stains and mildew may be formed due to this.

High-performance Grout

Walls and tiles have been one major worrisome factor after the construction of a house. The reason is corrosion, stain formation, mold and fungi formation etc. We can use high-performance grout for easy application and are stain-resistant too. The best tile grout for shower can be chosen as a high-performance type since it is very dense and easy to clean after drying. High-performance grout can be chosen for tiles that are expensive and require superior care in the long run.

Epoxy Grout

Epoxy grout for a shower is one of the best tile grouts due to its waterproofing design. You don’t have to use external sealers if you use epoxy grout for bathrooms. It is more popular than sanded grouts since it does not allow water, dust, dirt, grease etc., to seep in after curing. Stains and chemicals are also prevented from forming or entering tiles’ surfaces due to the presence of strong epoxy grout.

Grout vs Mortar


It is a viscous material that binds to narrow spaces, thus filling gaps rather perfectly. Grout is used mostly in binding tiles to its surface and preventing water from seeping through due to huge moisture and condensation formation. Less stiff than mortar. Water content is more in the grout, thus cannot be handled using shovel-like tools. Tubes, spray guns are the most preferred for grouting shower walls. Grouts are available in various colors as opposed to mortar. You can choose the color of our choice to build up our bathroom. Few grouts like sanded ones are porous. Water can move through small openings that can spoil the life of tiles or the material it is bound with.


Mortar is a combination of cement, sand, lime and water. Since water used in mortar is lesser than grout, mortar can be handled using tools like a shovel and other tools. The ability to work with mortar is easier since we don’t need specific tools to handle it. Mortar comes in its traditional form and color.

Setting time is more when compared to grout. The curing process also requires water. It is non-porous and hardens well after curing. Mortar is essentially used as a bonding material during construction and masonry.

How to Grout Floor Tile?

Grouting a shower can be a quick and easy process if we follow all the steps.

  1. Buy grout according to your needs. Check manufacturer’s instructions to find if it is ready-mix or has to be mixed.
  2. If it is a ready mix, no issues. Hand-mixing has to be done with careful instruction from behind grout tubs.
  3. Pour the required amount of water into the grout tub. Mix it well without lumps.
  4. Use appropriate clothing and face protection to protect from odor and toxic air during the grouting process.
  5. Apply the grout on a specialized brush or spray can or tubes with nibs to reach every narrow gap.
  6. Keep sweeping across each tile to attain a uniform coating.
  7. A sponge can be used to remove excess grout.
  8. Clean tiles after application with a dry cloth.

How to Clean Shower Grout?

Shower grouts can develop stains after long and repeated exposure to moisture. Stains, dirt, grease etc., may form on certain types of grout after a few years. To restore grout qualities, you can use a specialized grout cleaner or the best grout cleaner from the market.

If you prefer to use home-based cleaning methods, we can use baking soda or mild bleaches to remove hard stains. Few stains might require setting time from cleaning agents before removal. Hydrogen Peroxide can be used at home with baking soda to become a powerful homemade grout cleaner.

How to Grout a Shower Floor?

Grouting bathroom and shower floors follow the same methods. Best grout for shower floor can be applied to shower areas just like the rest of the bathroom tiles.

  1. Use a ready-mix or to-be-mixed shower grout. Mix according to the manufacturer’s instructions.
  2. Scoop out a small amount of grout and apply it to any tool used for grout application.
  3. We can even use a brush for successful grouting.
  4. The brush can be widely spread across the shower floor, holding at a 45° angle. This ensures grout is placed properly and at the correct pressure.
  5. Use a wet sponge to wipe out excess grout. The finished look is achieved only after this step.
  6. Wait for grout to set. Let the grout sit for around 24 hours to achieve the best results.

Sanded Vs Unsanded Grout – Which is Better?

Difference between sanded and Unsanded Grout

  • Sanded grout should not be used for narrow spaces. Unsanded grout is thinner and hence used for narrow gaps.
  • Sanded grout contains sand grains that may absorb water and not provide any waterproofing solution. Use unsanded epoxy grout for the best waterproof shower and bathrooms.
  • Sanded grout is thicker than unsanded grout, thus giving more durability. Shrinkage doesn’t happen in sanded grout. Unsanded grout does shrink and can be pulled away from tiles after a few years.
  • Sanded grout is not suitable for vertical surfaces. However, unsanded grout can handle vertical surfaces easily.

Make the right purchase according to the task at hand after weighing in pros and cons between the two.

How to Remove Grout?

Since grout holds itself firmly to the surface, it is being applied on, and we have to use special methods to scrape off grout from shower or bathroom tiles.

Few tools that can be used to remove grout:

  • Grout removal blade equipped tool
  • Saw with grout grabber blade
  • Rotary tool
  • Angle grinder – suitable for large grout removal
  • Manual grout removal tool – for smaller areas

Features to Consider While Choosing Best Grout for Showers

Before getting a Grout for your shower make sure to check the main considerations. These features will make sure you get a perfect shower grout for the use.

Pre-Mix or To-Be-Mixed

Pre-mixed grouts are comfortable for usage since you don’t have to mess with tubs and tools to mix grout and water. This is comfortable for many. On the other hand, we can use to-be-mixed grouts for tiling purposes. Instructions have to be followed as per the tub’s backside details. Pre-mixed are easy since you don’t have to meddle with ratios to achieve the perfect consistency. This type will flow out of tools easily as well for accurate application.

Package Type

Important information is the package type of grout brands. Grout for the shower floor is best when it arrives in tubes and spray gun bottles. Application in narrow spaces can be tricky when using external tools. A grout tube with nibs that directly fit in narrow spaces is mostly preferred for easy and accurate grouting. Bottles capable of fitting into spray guns can also be used since they are easy to refill if pre-mixed.

Sanded, Unsanded or Epoxy

Material used in grout is of great importance since we have to watch if it is sanded, unsanded or epoxy. Each type has its own benefits. Sanded can be used in huge gaps and for more durability. Unsanded can be used in places where gaps are very small and also for vertical grouting. Epoxy grout for a shower is the best solution for waterproof grouting without an external grout sealer to be used.
