You should wait at least 24 hours before using your shower, though 72 hours is recommended for cementitious grouts. Exposing fresh grout to water too early can cause it to wash away, crack, or become vulnerable to mold.
It is recommended to wait 3 days before using the shower. In some cases, where conditions are very humid and cold, or if ventilation is insufficient, it may take longer to dry.
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.
In most cases, it's best to wait 24 hours after tiling before grouting. This ensures that the adhesive has fully set and the tiles are firmly in place. If you rush the process and grout too early, you risk: Tiles shifting or moving, resulting in misalignment.
Grout drying time: On average, grout takes 24 to 72 hours to fully dry, depending on the type. Type of grout matters: Epoxy grout dries faster (around 24 hours), while cement-based grout may need more time. Weather plays a role: High humidity slows down drying, while good airflow speeds it up.
Sealer is not a waterproofer it is considered a moisture barrier and stain resistant. In over 30 years demoing tile showers the only time water gets behind grout is if it cracks and doesn't get repaired. Grout sealer is also not a one and done thing it wears and needs reapplied.
How to Tell — "When Grout Is Fully Dry?"
One very common regrouting mistake is spreading the grout unevenly between the tiles, forming “peaks and valleys.” This makes for a noticeably messy, uneven grouting job, and it can ruin the look of a tile wall or floor. The fact that grout shrinks as it dries makes this problem even harder to avoid.
Grout doesn't normally dry in 12 hours. Most grouts take 24-72 hours to set and become completely dry. Exactly how long it takes for grout to set depends on the type of grout you're using and the atmospheric conditions in the room.
High-traffic areas like mudrooms, kitchens, and master bathrooms should be professionally sealed more frequently, typically every 1-2 years. Low-traffic areas, like a guest bathroom or a decorative tile backsplash, can go much longer, often every 3-5 years. Type of Grout: The type of grout also plays a crucial role.
Bleach can also weaken grout and damage any sealer that's been applied. Over time, bleach makes grout more porous, which means it gets dirty even faster. Why to avoid: Like bleach, ammonia strips away protective sealers. It can also discolor grout and weaken the integrity of the grout over time.
One of the first signs of a sloppy job is grout lines that don't line up, or messy cuts. These are obvious aesthetic signs that the contractor is cutting corners. Even worse and less obvious are uneven tile surfaces, what's known as lippage.
Average Grout Longevity
Grout usually lasts from 8 to 15 years. The type of grout used is a primary determinant of its longevity. For instance, epoxy grout is known for its exceptional durability and resistance to water and stains, often outlasting traditional cement-based grouts.
If you're a die-hard DIYer, using Dawn dish soap alone can be a safer option for mild cleaning. Dilute a small amount of Dawn in warm water, scrub the grout with a soft brush, and rinse thoroughly. However, this method is less effective for tackling stubborn stains or deep-seated grime.
Typically, grout needs at least 24–48 hours to dry, and many manufacturers recommend even waiting a full 72 hours for showers or high-moisture areas. Always follow product recommendations and call the manufacturer if you have any questions.
SameDay Grout Sealer can be applied as soon as 6 hours after grouting making sealing an efficient, economical process. The easy-to-spray nozzle places more sealer on the grout. Surface should be dry, clean and free of waxes, sealers or finishes.
The shortest time after laying tile that you can grout is 24 hours. However, it is much better to wait at least 48 hours before grouting. This is to give the mortar ample time to set and dry before pressure is applied.
The 1/3 rule (or 33% offset) is a tile-laying technique that staggers rectangular tiles, especially longer ones like timber look or large-format porcelain, by one-third of their length instead of halfway. This reduces tile lippage (uneven edges), improves surface smoothness, and enhances visual flow.
It's maybe a little on the slow side but it sounds like you're just making sure to get it right. A good grout job that takes a little longer is way better than a bad grout job that you did fast. That shower would usually take me about an hour to an hour and a half. It depends on what grout you use also.

Fortunately, tile regrouting is not particularly tricky; it just requires you to invest the right time and materials into it in order to complete the job properly.
Just a few more important points: As the grout can absorb the soap as well as a stain, do not clean with oil or wax based cleaners (Murphy's Oil soap, Pine Sol, etc.). These products will leave a waxy or oily film in the grout. Even good alkaline cleaners, if not properly rinsed, will leave a sticky soap film.
