The only type of grout that doesn't need sealer is epoxy, which is inherently pre-sealed. Grout sealers typically come in two forms-- spray-on sealers and applicator sealers. Applicator sealers are applied directly to the grout with a roller ball or a brush.
Grout is a cement-based product mixed with chemicals, water, and in many cases sand. Portland cement based grouts are particularly porous. Porous grouts attract water, dirt, oils, etc. While the tile industry does not require sealing, it is always recommended, especially in wet or high-traffic areas.
Whoever installed your floors most likely did not seal the grout because it needs time to harden and cure completely.
Sealants are usually unnecessary for ceramic or porcelain tiles. There are some exceptions to this, so check with your manufacturer. Sealants are necessary for natural stone (slate, marble, granite, travertine, etc.).
Sealing grout helps protect against moisture and stains. Sanded and unsanded grout needs a sealer; epoxy grout doesn't. Shower grout should be resealed every year. Grout in other areas of your home should be sealed every couple of years.

MAPEI's Keracolor U is a cement-based grout and is porous. Therefore, it will absorb stains and should be sealed. Sealing Keracolor U grout will help to maintain it, keep it clean and minimize discoloration. Choose a high-quality grout sealer, such as our UltraCare® Penetrating Plus SB Stone & Porcelain Tile Sealer.
The Drawback of Using Grout Sealer
Moisture can still pass through most sealers, meaning grout isn't entirely waterproof even when sealed. Over time, grout in areas like bathrooms will naturally stain or show signs of aging, regardless of sealing.
What Happens If You Don't Seal Your Tile? Choosing not to seal your tile decreases its lifespan and makes cleaning and maintenance more difficult and labor-intensive. If you have porous tile, like natural stone or unglazed ceramic, a variety of stains are bound to accumulate on its surface.
Although not required, for optimal results, Ultracolor Plus FA or Ultracolor Plus Max may be sealed - especially in places such as showers. Sealers make grout maintenance easier in the long run.
Moisture can penetrate the grout, causing it to expand and contract, leading to cracks and gaps between tiles. These openings not only look unsightly but can also allow further moisture intrusion, potentially leading to structural damage to the underlying substrate.

Many companies don't automatically include grout sealing in a job with new tile flooring for a few reasons. First, companies can't seal grout until at least 48 to 72 hours after applying grout. By that time, bathroom remodelers typically have already cleaned up from the job and left your home.
To maintain the integrity of grout, you will have to apply a grout sealer. It is necessary to apply the sealer after 1 to 2 years so that the grout remains intact and waterproof. Sealing grout is necessary because it without a waterproof covering it absorb not just water but bacteria and stains as well.
You can seal the grout the day after you applied it or 100 years later. If it isn't dirty, seal all three sides of the shower with a tile sealer or masonry sealer. That will make the grout water-resistant, if not waterproof, and help prevent the growth of mold and dirt.
The average cost to seal grout is $150 to $250 for 160 square feet of space, including materials and labor, though the price depends on the size of your tiles and the condition of your grout.
Grout tends to wear away more quickly when it is not sealed, so it will crack, discolor and become hard to manage when cleaning. This will force you to replace it more often than if it was sealed, leading to higher costs overall.
Which tiles need to be sealed? As mentioned, tiles with a porous surface need to be sealed. These include wall tiles with a crackle glaze, most types of natural stones and some man-made tiles, such as quartz, cement and terracotta tiles.
PERMACOLOR® Select does not require sealing, however, if even greater protection is desired, the following STONETECH products listed below may be used. Note - for maximum stain protection and performance, use SPECTRALOCK® PRO Premium Grout.
Epoxy grout doesn't need to be sealed at all.
First of all you don't really need to seal your grout. I assume it is a cementitious grout, which is porous. Put generally speaking you don't have to seal it. It will get darker over time whether you seal it or not, but it will be easier to clean and will less likely stain if you do seal it.
Most porcelain tiles won't need sealing, as they are naturally robust and offer water resistance. However, if you have polished porcelain or other porous tiles they must be sealed to stop water from entering and damaging the tile. Unsealed tiles can stain, and attract dust and dirt which can be difficult to clean.
Tile or stone with high absorption, surfaces that are porous or rough, textured surfaces and some types of porcelain tile may require sealing prior to grouting to prevent possible staining. Use Aqua Mix® Grout Release or TileLab® SurfaceGard® Sealer to prevent staining when required.
