Tile for Kitchens and Bathrooms How to Choose Backsplash, Wall, and Floor Tile That Lasts

Tile is one of those decisions that seems simple until you're standing in front of hundreds of options and realizing you're not entirely sure what you're looking at. Porcelain or ceramic? Large format or small? Sanded or unsanded grout? And what does PEI rating actually mean?

Here's the good news: once you understand a few core concepts about tile products, the choices get a lot clearer. This guide covers what you need to know about tile materials, grout, sizing, layout patterns, and what professional installation actually gets you so you can make decisions you'll be happy with for years.

The Three Main Materials

Ceramic

This is the most affordable option and a solid performer in kitchens and bathrooms. It's made from clay fired at lower temperatures than porcelain, which makes it slightly softer and more porous. But for wall tile, backsplashes, ceramic is a perfectly capable material.

Ceramic is also easier to cut and work with than porcelain, which makes it a more DIY-friendly option. The tradeoff is that it's more prone to chipping under impact.

Porcelain

Porcelain is fired at higher temperatures from a denser clay mixture, which makes it harder, less porous, and significantly more moisture resistant than ceramic. With a water absorption rate of less than 0.5%, porcelain is effectively waterproof. This is why it's the go-to for shower floors, bathroom floors, and kitchen floors where spills and moisture are constants.

Many porcelain tiles carry a PEI hardness rating of 4 or 5, making them suitable for high-traffic floors and even commercial applications. It costs more than ceramic and requires more specialized tools to cut, but for high-use wet areas it's the more practical choice. For most NJ kitchens and bathrooms, porcelain on the floor and either porcelain or ceramic on the walls and backsplash is the standard.

Natural Stone

Marble, travertine, slate, and quartzite bring something that no manufactured tile can replicate: remarkable variation, depth, and the kind of organic beauty that photographs well and ages gracefully. It's the right call when you want a high-end, one-of-a-kind look and you're prepared for what that requires.

Here’s the part people often skip over: natural stone needs regular sealing for stain and water resistance, unlike porcelain which generally doesn't need resealing beyond the grout. Stone is porous, which means spills that sit too long can stain, and acidic cleaners that you'd use anywhere else in the house can damage the surface. Consider these factors if you’re looking for something low maintenance.

Grout: The Part Everyone Underestimates

Grout is one of the most overlooked decisions in a tile project, but it plays an important role in how the finished installation looks and holds up over time.

• Sanded grout is used for joints wider than 1/8 inch. The sand additive gives it body and prevents shrinkage in wider gaps, making it the right choice for floor tile and any backsplash or wall application with a larger grout joint.

• Unsanded grout is used for joints 1/8 inch or narrower, common in wall tile and mosaic applications. It has a smoother texture that works well on polished or delicate tile surfaces where sanded grout could cause scratching.

• Epoxy grout is worth knowing about for high-use or high-moisture applications. Unlike cement-based grout, epoxy is non-porous, stain-resistant, and doesn't require sealing. It's used in commercial kitchens for this reason, along with heavily used showers or kitchen floors in residential applications.

• Grout color matters more than people realize. Light grout shows staining more readily in a kitchen. Dark grout can fade unevenly over time in a high-moisture shower. Medium tones tend to perform and look the best over the long run. And regardless of what color you choose, sealing cement-based grout after installation and periodically thereafter is one of the simplest ways to extend the life of your tile work.

Sizing and Layout: Backsplash Considerations

This is where personal style comes in, but a few practical guidelines apply regardless of aesthetic preference.

Tile Size Relative to the Space

Larger format tiles (12x24 or bigger) can make a smaller kitchen feel more expansive and reduce the number of grout lines for a cleaner look. Smaller tiles—classic 3x6 subway, 2x2 mosaic—add more visual texture and are more forgiving on walls that aren't perfectly flat.

Layout Patterns Change the Whole Feel

A basic stacked layout is clean and contemporary. A classic offset (running bond) is timeless and works with almost any kitchen style. Herringbone and chevron patterns add movement and visual interest, though they also add installation time and material waste, which affects cost. If you're doing a more complex pattern, budget 10–15% extra material for cuts.

The Backsplash-to-Countertop Relationship

The grout joint size and tile color should be considered alongside your countertop. A heavily veined countertop pairs best with simpler tile. A simple solid countertop gives you more room to introduce pattern or texture in the backsplash.

Professional vs. DIY Installation

Tile installation looks more manageable than it is, and the results of a mediocre installation announce themselves over time in ways that are hard to miss: uneven grout lines, tiles that crack because they weren't set properly, or grout that fails early because the substrate wasn't right.

There are cases where DIY works. For example, a simple ceramic tile backsplash in a kitchen with a flat surface, straightforward layout, and forgiving material may be achievable with patience and the right tools. Same for a small bathroom accent wall with standard-size tile and a simple pattern.

However, most cases call for professional installation. Floor tile, shower tile, large format porcelain, natural stone, and any layout pattern beyond a basic stacked or offset run all benefit from professional installation.

Porcelain's density and hardness require specialized tools and technique that most DIYers don't have on hand. Large format tiles need an extremely flat substrate, as any unevenness causes lippage (where tile edges don't line up). And shower installations require proper waterproofing behind the tile to avoid moisture damage behind your walls.

The rule of thumb: the higher the stakes of failure, the more professional installation is worth the investment.

Choose Tile That Looks Good and Holds Up

The right tile can completely change the way a kitchen or bathroom looks, but the best choice is not just about color, pattern, or style. Backsplash, wall, and floor tile all need to be selected with the space in mind, including moisture exposure, foot traffic, cleaning needs, slip resistance, and long-term durability. When you understand how each tile will perform in the room where it’s being installed, it becomes much easier to choose a product you will still feel good about years from now.
