Yes, you should seal your grout. While it won't make the shower waterproof (true waterproofing happens behind the tile), a penetrating sealer creates a protective barrier that repels moisture, prevents stains, and stops mold and mildew from easily taking root in the porous cement.
Without a protective sealant, spills, splashes, and everyday use can lead to the penetration of liquids and contaminants into the grout lines. Over time, this absorption can cause grout to become discolored, taking on a dingy and unsightly appearance.
Builders often skip sealing grout to cut costs, save time, and avoid returning to the job site. Additionally, many modern polymer-modified grouts are stain-resistant, and sealing un-cured grout can trap moisture. Some installers even use it as an upsell or exclude it because sealing can leave a hazy film on certain tiles.
Yes, sealing your shower grout is highly recommended. While it doesn't make the shower waterproof (that relies on the backing behind the tile), sealing creates a protective barrier that resists water, soap scum, and stains. It also prevents mold growth and makes the grout much easier to clean.
Sealing grout creates a protective, stain-resistant barrier, but it comes with several disadvantages. It requires frequent reapplication, traps moisture if applied incorrectly, is not foolproof against staining, and adds upfront costs.
Grout sealer typically lasts between 1 to 5 years, but the exact lifespan depends on the type of sealer used and the location of your tile.
For shower tile and grout, the best sealers are penetrating, water-based or solvent-based impregnators. They absorb into the porous grout to create an invisible, breathable barrier against moisture, mildew, and soap scum.
When choosing between spray and brush grout sealers, spray is faster and better for large floor spaces, but wastes product and requires cleaning the tile surface. Brush (or roller) application takes longer but offers precision control, ensuring the sealer only goes on the grout without splattering.
Epoxy and advanced urethane/acrylic grouts do not require sealing. Unlike porous cement-based grouts, these synthetic options are completely waterproof, highly stain-resistant, and chemically dense, making them ideal for high-moisture areas like showers, backsplashes, and high-traffic floors.
One of the most frequent grouting mistakes is improper mixing and application. Grout is a precise material, and getting this step right is crucial for its strength and adhesion. Incorrect Water-to-Grout Ratio: Adding too much or too little water can significantly weaken the grout.
Most installers will not seal the tile surfaces right away to ensure that the grout has enough time to cure completely. However, once the grout is completely dry, using a sealer to protect it would be a smart decision. Grout recoloring and sealing has many benefits to help keep up your home and protect your investment.
To tell if your shower grout is sealed, perform a simple water test. Dribble or spray a few drops of water onto the grout lines. If the grout darkens or absorbs the water, it needs to be sealed. If the water beads up and the grout color remains unchanged, it is effectively sealed.

Yes, you can absolutely seal grout yourself. It is a highly manageable DIY project that requires very few tools and will extend the life of your tile.
Professional grout sealing costs between $𝟏.𝟓𝟎 and $𝟒.𝟎𝟎 per square foot for labor and materials, or roughly $𝟏𝟐𝟓 to $𝟑𝟎𝟎 for a standard bathroom or kitchen area. If you DIY, you can seal the grout yourself for as little as $𝟎.𝟐𝟎 to $𝟎.𝟓𝟎 per square foot in supplies.

Whether your grout needs sealing depends entirely on the type of grout you use. The short answer: cement-based grout requires it, while epoxy grout does not.
To prevent the development of mold and mildew, it is important for you to seal your grout at least once a year. However, one of the best practices for you is to seal grout every six months in high traffic areas. Moreover, you can seal grout every two years in low traffic areas.
The best overall grout sealer is Miracle Sealants 511 Impregnator. It is a highly penetrative, solvent-based sealer that absorbs deep into porous cementitious grout lines to form an invisible, oil-and-water-resistant barrier without changing the natural look of your tile or grout.
Store-bought sealers can help, but even they don't work properly unless the floor is deeply cleaned first. If dirt remains trapped in the grout when sealer is applied, that dirt becomes sealed in permanently. It is imperative that sealing take place only on thoroughly clean grout.
Grout sealer typically lasts between 1 to 5 years, but the exact lifespan depends on the type of sealer used and the location of your tile.
Some may use mechanical brushes to scrub grout and remove tough stains. From there, professional cleaners may use a wet vacuum to extract dirty water and cleaning residue to dry the area, completing the job with a grout sealer to protect against future stains.
Unlike a thin, clear sealant that wears away quickly, grout color sealing utilizes a durable epoxy-based formula. This advanced sealant penetrates the porous grout and creates a non-porous, permanent bond.
Yes, Dawn dish soap is excellent for cleaning grout because its gentle, grease-cutting formula will not strip sealers or discolor tile. For everyday maintenance, simply mix a dime-sized squirt of Blue Dawn in a 32-oz spray bottle of warm water. For tougher grime, you can upgrade to a deeper-cleaning DIY mixture.
