When homeowners plan a new tile floor, they agonize over the tile — the size, the color, the pattern, the finish. Then, almost as an afterthought, they pick a grout. It's an easy mistake to make, and it's one of the most consequential. Grout typically makes up only a small fraction of your floor's surface, but it outlines every single tile, influences the entire look of the room, and does critical structural work holding your installation together. Choose well, and your floor looks crisp and cohesive for decades. Choose poorly, and even expensive tile can look dingy within a year.

At Floors 2 Buy in Lancaster, PA, we've helped thousands of homeowners get both the tile and the grout right. Here's our complete guide to choosing the right grout for your new tile floor — and keeping it clean for the long haul.

What Grout Actually Does

Grout isn't just a filler. It locks tiles in alignment so they can't shift against each other, absorbs the small dimensional variations between tiles, keeps moisture and debris from working beneath the surface, and visually frames every tile in the layout. A well-grouted floor is a system — tile, setting mortar, and grout working together. That's also why grout failures (cracking, crumbling, staining) usually point to a deeper installation issue, not just a surface problem. If you'd like a primer on tile itself before diving into grout, our tile flooring information page covers the basics of porcelain and ceramic construction, durability, and care.

The Three Main Types of Grout

Sanded Grout

Sanded grout is a cement-based grout with fine sand added for strength. The sand prevents shrinking and cracking as the grout cures, which makes it the standard choice for floor joints 1/8 inch and wider. It's durable, economical, and available in a huge range of colors. Its one caveat: the sand content can scratch delicate polished surfaces like marble, so it's not right for every project.

Unsanded Grout

Unsanded grout omits the sand, giving it a smooth, creamy texture that clings well in narrow joints under 1/8 inch — think tightly-set wall tile, polished stone, and some rectified porcelain layouts. On floors, unsanded grout should only be used in genuinely narrow joints; in wide joints it will shrink and crack.

Epoxy Grout

Epoxy grout is the premium option, made from resins and hardeners instead of cement. It is essentially non-porous — meaning it resists stains, doesn't need sealing, stands up to harsh cleaning, and shrugs off moisture. For kitchens, mudrooms, laundry rooms, and busy family bathrooms, epoxy grout is a game-changer. It costs more and demands experienced hands during installation (it sets fast and is unforgiving), but over a floor's lifetime, many homeowners find it pays for itself in avoided maintenance.

Choosing Your Grout Color: The Decision That Changes Everything

Two identical tile floors can look completely different depending only on grout color. There are three basic strategies:

•      Matching grout (grout close to the tile color) creates a seamless, continuous surface. The tile pattern recedes and the room reads as one calm expanse — ideal for making smaller Lancaster-area bathrooms and kitchens feel larger.

•      Contrasting grout (light tile with dark grout, or the reverse) outlines every tile and turns the layout itself into a design feature. It's striking with subway patterns and geometric layouts — but be certain you love the pattern, because contrast highlights any imperfection in tile alignment.

•      Neutral 'greige' tones sit in the middle: enough definition to show the layout, enough softness to forgive everyday dust and traffic. Mid-tone grays and greiges are our most-recommended floor grout colors, because very white grout shows dirt quickly and very dark grout can fade unevenly in sunlight.

A pro tip from our showroom: always look at a dried grout sample against your actual tile, in the lighting of your actual room. Wet grout dries noticeably lighter, and showroom lighting differs from your kitchen's. When you shop our tile collection, our team will put physical grout samples next to your chosen tile so there are no surprises on installation day.

Grout Joint Width and Tile Size

Grout choice is also tied to the tile you've selected. Large-format tiles — 12x24 inches and beyond — are typically installed with narrow joints for a sleek, modern look, which affects which grout types are suitable. Handmade and rustic tiles need wider joints to absorb their charming irregularity. Rectified tiles with precision-cut edges permit the tightest joints of all. This interplay between tile format, joint width, and grout type is exactly the kind of detail our design team helps you navigate when you browse the full flooring catalog at our Lancaster showroom.

Keeping Your Grout Clean: A Realistic Maintenance Plan

Grout gets a bad reputation for being hard to maintain, but most grout problems come from either the wrong product choice up front or well-intentioned cleaning mistakes later. Here's what actually works:

•      Seal cement-based grout. Sanded and unsanded grouts are porous and should be sealed after curing, then resealed roughly every one to two years in busy areas. (Epoxy grout skips this entirely.)

•      Clean with pH-neutral cleaners. Vinegar, bleach, and harsh acidic cleaners slowly dissolve and weaken cement grout. A pH-neutral tile cleaner and warm water handle routine cleaning safely.

•      Scrub gently, not aggressively. A soft nylon brush lifts dirt from grout lines without scratching surrounding tile. Avoid metal brushes and overly abrasive pads.

•      Wipe spills promptly. Coffee, wine, and pet accidents stain porous grout if left to sit. Quick cleanup prevents 90% of staining.

•      Refresh, don't despair. If older grout is stained beyond cleaning, professional regrouting or color-sealing can make a tired tile floor look new again — often for far less than replacement. Our flooring repair services can help you decide which route makes sense.

Why Grout Is a 'Get It Right the First Time' Decision

Unlike paint or hardware, grout isn't something you casually swap out later. Removing and replacing grout is labor-intensive, which means your grout decisions — type, color, joint width, and sealing — will be with you for the life of the floor. Proper mixing, working time, joint packing, and curing all affect whether grout reaches its full strength and color consistency. It's precise, unforgiving work, and it's a big part of why professionally installed tile consistently outlasts DIY installations. Floors 2 Buy's experienced crews handle every step through our residential and commercial installation services, so your grout cures strong, even, and exactly the color you picked. You can read how those installations turn out for your neighbors on our customer reviews page.
