Tile can look bulletproof. It isn’t.

A tile job lasts decades when the boring parts are done obsessively well: flat substrate, controlled moisture, correct mortar coverage, movement joints in the right places, and a grout system that fits the room, not your mood at the store.

Start with taste… then get ruthless about practicality

Most people choose tile like they’re choosing paint: “I like this color.” Fine. Pick the look you’ll still like when the trend cycle moves on.

But if you stop there, you’re setting yourself up for regret.

Here’s the part people skip: the grout is half the visual field on many installations, especially mosaics and small-format layouts. A slightly warmer “soft gray” can make white tile feel creamy and intentional; the wrong bright-white grout can make a premium tile look cheap within six months of use (because it won’t stay that white) unless you partner with an experienced installer to ensure a lifetime finish.

Now, this won’t apply to everyone, but if you have kids, pets, a busy entry, or hard water, don’t romanticize high-contrast grout. It’s work. Constant work.

The materials: choose like a pessimist

I’m opinionated here: porcelain is the default for floors in most homes unless there’s a strong reason not to. It’s dense, low-absorption, and generally shrugs off daily life.

A quick technical anchor:

– Porcelain tile water absorption is ≤ 0.5% by definition (ANSI A137.1). That low absorption is a big reason it behaves so well in wet zones and freeze-thaw situations.

Source: Tile Council of North America (TCNA), ANSI A137.1 Specifications for Ceramic Tile (referenced by TCNA standards).

For high-traffic floors, pay attention to wear ratings and surface finish. Glossy looks sharp in a showroom and then shows everything, grit, scuffs, micro-scratches. Matte or textured finishes age more gracefully (and you’ll worry less).

Large format tile can be fantastic, but it’s not a shortcut. It demands flatter floors than most houses naturally have.

If your floor isn’t flat, your tile job is already failing.

That’s not drama. That’s physics.

Tile and grout don’t like bending. Substrates move. Your job is to reduce movement, manage it where you can’t, and keep the tile supported.

A few prep realities (the unsexy ones)

– Clean means clean: dust, overspray, curing compounds, old adhesive, gone.

– Flatness matters more as tile gets bigger.

– Cracks in concrete don’t disappear because you ignored them.

– Wood subfloors need stiffness; bounce kills grout lines over time.

I’ve walked into plenty of “mystery crack” jobs where the homeowner blamed the tile, blamed the grout, blamed the installer… and the real culprit was a wavy substrate that never got corrected. The tile was just the messenger.

One-line truth:

Flat is cheaper than fixing.

Layout and cutting: the part that separates “installed” from “crafted”

Look, you can tell who planned and who panicked.

A good layout isn’t just centered lines and good vibes. It’s decisions: where you hide smaller cuts, how you handle transitions, which wall is actually straight (spoiler: often none), and whether your focal line respects what the eye sees when you enter the room.

Technical mode for a second: you want consistent joint widths, controlled lippage, and adequate mortar coverage. That means the right trowel notch, correct mortar consistency, and periodically lifting a tile to confirm transfer. If you don’t check coverage, you’re guessing. Guessing is how voids happen, and voids are how tiles crack under point loads.

And yes, dry-fitting matters, especially on patterned tile, directional textures, or anything with a visible caliber variation.

Grout: not just “the stuff between tiles”

Grout is a structural participant. It also takes abuse: water, cleaners, foot traffic, hair dye, cooking oil, whatever life throws.

Cement grout vs epoxy (my blunt take)

Cementitious grout is fine for many interiors if mixed and cured correctly. Epoxy grout is the “I don’t want to think about this again” option, more stain resistant, less porous, tougher overall, but fussier to install and pricier.

If you’re doing a shower, mudroom, or a kitchen that actually gets used, epoxy can be worth the pain. I’ve seen homeowners spend thousands on tile and then cheap out on grout like it’s an afterthought. That’s backwards.

Color longevity is its own rabbit hole. Pigment stability, UV exposure, and cleaning chemistry all matter. If you hit cement grout with harsh acidic cleaners repeatedly, it won’t just fade, it can erode.

Wet areas: waterproofing is the job, tile is the decoration

Question: Do you want your shower to be waterproof, or do you want it to look waterproof?

They are not the same.

Tile and grout are not your waterproof layer. They’re a wear surface. The real protection is behind them: a bonded waterproofing membrane or a properly built pan/liner system, correctly detailed at corners, seams, penetrations, and drains.

A few things that regularly go wrong:

– Missing or sloppy membrane seams

– No slope to drain (water sits, then finds a way)

– Penetrations not sealed correctly

– Mixing incompatible products because the shelf guy said “it should work”

Follow one manufacturer’s system when you can. Frankensteining materials is how warranties evaporate.

Sealing and maintenance: boring, but it’s your finish line

Some tile doesn’t need sealing. Many grouts do. Natural stone almost always benefits from the right sealer (and the wrong one can leave a hazy film that drives you nuts).

Here’s the thing: sealing isn’t a magic shield. It buys you time to clean spills before they become stains.

A realistic maintenance rhythm:

– Dry dust/grit removal often (grit is sandpaper)

– pH-neutral cleaner for routine washing

– Reseal grout/stone on the schedule the product actually calls for, often every 1, 3 years, depending on traffic and chemistry

And please, avoid “miracle” acidic bathroom cleaners on cement grout unless the grout manufacturer explicitly allows it. Cleaners can be the slowest form of damage.

Mistakes pros avoid (because they’ve already paid for them once)

A short list, because you don’t need a novel:

– Skipping expansion/movement joints and then acting surprised when corners crack

– Setting tile over a substrate that isn’t flat enough for the tile size

– Not checking mortar coverage (voids everywhere, quietly waiting to fail)

– Rushing cure times, thinset and grout aren’t impressed by your schedule

– Using the wrong trowel/notch and starving the bond

– Choosing pretty tile + bargain adhesive + random sealer and hoping they “play nice”

Picking tile by room: practical, not precious

Kitchens: prioritize cleanability and stain resistance. Matte porcelain wins a lot of arguments here.

Bathrooms: slip resistance matters more than you think, especially on small shower floors. Also, build the waterproofing like you never want to open that wall again.

Hallways/entries: grit and moisture are constant. Durable body, decent abrasion rating, and grout that won’t look filthy by week three.

Living spaces: if you hate noise, tile will amplify it. Area rugs, underlayment choices, and layout decisions can help, but tile is still tile.

Outdoor: verify freeze-thaw rating and use products designed for exterior exposure. Sun is brutal on cheap finishes.

A few questions I’d ask before any job starts

No fluff, these are the ones that prevent rework:

– Is the substrate flat enough for this tile size (not just “kinda flat”)?

– What waterproofing system is being used, and is it a complete system or a mix?

– Where are movement joints going, and how are transitions handled?

– What grout type matches this room’s abuse level?

– Can I get replacement tile from the same run, or do I need attic stock?

– What are the cure times at the actual site temperature and humidity?

If you can answer those cleanly, you’re already ahead of most “tile problems” I get called to diagnose.
