Our Techs Transformed a Shower in Manhattan With Our Amazing Grout Sealing Service

November 13, 2025

A large shower can give you all the comfort you need, but it can also turn routine maintenance into an uphill battle if you don't have the means to counter the effects of moisture buildup. A Manhattan resident tried different ways to restore the marble surface of his shower floor, but his efforts only seemed to make the dirt stand out more. He knew that he couldn't expose natural stone surfaces to harsh ingredients, but this left him with few options to clean the shower floor.


That's why he ultimately decided to contact a professional grout sealing service in Manhattan, so he went online looking for options. He found Sir Grout Manhattan only minutes into his search, and once he started reading about our services, the owner didn't need to check other companies in the area. That same day, he reached out to us via the website's contact form, and a date was set for an in-home evaluation.

Our specialists went to his house on the scheduled date, later that week, and the owner immediately spotted our vehicle's identification. Inside the shower, we evaluated the large marble surface, observing all the grout lines on the floor, along with the marble tiles. We noticed several details early on, like the etch marks on the stone and the discoloration on parts of the grout.

We praised the owner for avoiding many of the most abrasive formulas on the market, but unfortunately, the floor had still been exposed to harsh ingredients, from the minerals in hard water to the soap in other cleaning products. The solution was a multi-step process to revamp the stone and seal the grout. Our experts explained the importance of sealing porous surfaces, stating that there's no better way to keep the dirt from adhering to the grout after constant exposure to moisture. The client agreed with this approach and asked us to return at a later date for the restoration.

At his convenience, we returned to the house after a couple of days and immediately prepared the shower area, covering the surrounding surfaces with clear plastic and masking tape. Then, we soaked the floor with a stone-safe formula before scrubbing off the embedded dirt, including the efflorescence that permeated the marble tiles and the calcium on the grout. We also steamed cleaned the entire shower stall to address all the moldy spots between the tiles.

Next, our experts used three sets of diamond pads to remove all the etch marks on the tiles. We increased the level of grit as the imperfections faded from the floor, eventually leaving the entire surface with a nice matte finish. That was our cue to apply special polishing powders to complete the job and restore the marble's natural sheen.

Before moving on to the grout's restoration, we applied sealant on the floor, enhancing its protection against the effects of wear and tear. The marble would keep its brand-new look for much longer without collecting stains or etch marks after weeks of activity.

At this point, our crew was ready to revamp the floor's grout. We used Sir Grout's flagship ColorSeal to recolor all the grout lines on the floor and complete the shower's original layout. Our acrylic-based sealant guarantees lasting protection against water, grime, soap scum, mineral residue, and other external elements, so you can go for months without dealing with embedded dirt on the grout pores.

The marble surface looked spotless, and there were no hints of damage on the grout. Naturally, the client was thrilled with his shower's new look and promised to contact us whenever he started seeing signs of decay on any of his bathroom surfaces.

He also told us that he was worried about mold spreading around different parts of the bathroom, so our techs gave him some useful pointers. First, we introduced the most powerful way to fight the effects of moisture buildup. Sir Grout's Natural Hard Surface Cleaner removes mold, mildew, and efflorescence much more effectively. It doesn't have any toxic ingredients and leaves no residue on your floors, so you can keep the surface looking spotless for much longer. pH-neutral products are the best option for the maintenance of natural stone surfaces; they provide more cleaning power without subjecting your shower to harsh treatment, so you don't have to worry about triggering any damage after using these products during your weekly cleaning routine.

Our cleaner also works best when combined with non-abrasive tools, which is why we always recommend scrubbing off the dirt with a towel or a squeegee to avoid any scratches. Regular cleaning sessions with the right equipment can work wonders on the appearance of your bathroom surfaces, especially when they get enough fresh air throughout the day. Good indoor ventilation does a lot to help you preserve your cleaning results, so it never hurts to open the windows when the air starts to feel stale.
