Bathroom Tile Selection: What to Choose and Avoid
The tile that looks perfect on a showroom board under ideal lighting gets installed in a bathroom where it faces soap, shampoo, hard water, steam, and daily use. Within a year or two, some homeowners are calling their contractor about a tear-out.
Blake Becker of Becker Custom Builders has retiled more bathrooms than he can count and sees the same pattern repeat: beautiful tile installed in the wrong environment, failing in ways that were predictable before the first box was opened.
In the video above, he covers the six tile types that cause the most regret, why each fails, what they cost to install and fix, and the alternatives that look nearly identical without the upkeep. For more bathroom guides, see our bathroom remodeling guide.
The tile itself is only half the equation. What is behind it, the waterproofing membrane, grout, and substrate, decides whether an installation lasts five years or thirty. A porcelain tile over poorly waterproofed backer board fails just as surely as the wrong tile in the wrong place; the tile just gets the blame. Our bathroom waterproofing guide explains what should be behind every shower wall.
The 6 Tiles at a Glance
Tile | Why it causes problems | Better choice |
|---|
Marble in the shower | Etches from acids; porous; needs sealing every 6 – 12 months | Large-format porcelain with marble veining |
Pebble shower floor | Heavy grout; low spots where water pools | Matte porcelain in 2x2 or 4x4 |
Fluted or textured wall tile in showers | Grooves collect soap scum and mildew; costly to install | Use it as an accent wall outside the shower |
Zellige and handmade tile in wet areas | More porous; hard to match for repairs | Backsplashes and decorative walls |
Small mosaic on floors and walls | Grout line every inch; more cleaning and staining | Larger formats, or mosaics as accents with epoxy grout |
Glass tile in the shower | Thinset shows through; little margin for error; slippery on floors | Walls and accents only, by an experienced installer |
Costs below are Blake Becker’s figures from the video.
1. Marble Tile in the Shower
Marble is calcium carbonate, so it reacts to acids. Shampoo, conditioner, body wash, and even hard water can etch the polished surface over time. Etching isn’t a stain that wipes off; it is permanent dullness where the acid breaks down the finish, and the only fix is professional rehoning and repolishing.
Marble is also porous, one of the worst traits a shower material can have. If it isn’t sealed before and after installation and resealed every six to twelve months, moisture can work behind the tile and into the wall. That is often how mold begins, and the damage usually stays hidden until it is serious.
In Becker’s figures, Calacatta marble runs $25 to $80 per square foot plus $10 to $25 per square foot to install, and a typical shower enclosure $5,000 to $9,000 before waterproofing, with ongoing sealing and periodic professional rehoning.
Better choice: large-format porcelain with marble veining gives a similar look with far less upkeep.
2. Pebble Tile Shower Floors
Pebble tile looks impressive in photos, but owning it is different. The irregular shapes need far more grout than standard tile, and more grout means more surface for soap residue, hard water deposits, mildew, and mold.
Drainage can suffer too. A shower floor needs a consistent slope to the drain, and pebble’s uneven surface can leave low spots where water pools between the stones.
Better choice: for texture and traction, use matte porcelain in a 2x2 or 4x4 format with a wet slip rating (DCOF) of at least 0.42 under ANSI A326.3; Becker prefers 0.50 or higher. These drain properly and are easier to keep clean.
3. Fluted and Textured Wall Tile
Fluted tile creates dramatic visual interest and works well in living rooms, powder rooms, and feature walls. In a shower, every groove collects soap scum, hard water deposits, mildew, and daily grime, and cleaning a fluted shower wall takes much more effort than a flat one.
Installation costs more as well, because grooves must line up at every joint. Becker puts standard wall tile installation at $8 to $15 per square foot and fluted tile at $15 to $25.
Better choice: use fluted tile as an accent wall outside the shower rather than throughout a wet area.
4. Zellige and Handmade Tile in Wet Areas
Zellige is known for its handcrafted look and the way it reflects light. It is generally more porous than porcelain or ceramic because it is fired at lower temperatures. In wet areas that can mean water absorption, tile expansion, cracked grout, crazed glaze, and difficult repairs, and matching replacement tiles is hard because handmade lots vary between production runs.
In Becker’s figures, zellige material runs $15 to $45 per square foot plus $15 to $30 to install, about $3,000 to $4,500 for a typical 50-square-foot shower before waterproofing.
Better choice: many homeowners find zellige works best on vanity backsplashes and decorative walls rather than inside a shower used every day.
5. Small Mosaic Tile on Shower Floors and Walls
The challenge with mosaic tile is grout. A large-format tile may have a grout line every 12 to 24 inches; a 1x1 mosaic has one every inch. More grout means more maintenance, more cleaning, more chances for staining, and more discoloration. Installation also costs more because mosaic sheets need precise alignment and leveling: Becker puts it at $15 to $25 per square foot, versus $8 to $15 for standard tile.
Better choice: use mosaics as accents rather than primary surfaces. When they go on a shower floor, epoxy grout is strongly recommended for its resistance to staining and mildew. For how tile size affects shower floor slope, see our curbless shower cost guide.
6. Glass Tile in the Shower
Glass tile can be beautiful, but it leaves very little margin for installation error. Because glass is translucent, the adhesive behind it shows through, so any inconsistency in the thinset can remain visible, along with color variation and other defects. Glass is also a poor choice for shower floors, where its smooth surface becomes slippery when wet.
Becker puts glass tile material at $20 to $100 per square foot, with installation costing more than standard tile because of the specialized work. Mistakes often mean complete removal and replacement, which makes glass one of the most expensive tiles to get wrong.
What to Choose Instead
The tile that consistently performs well in bathrooms is large-format porcelain in a matte or satin finish. It is non-porous, durable, and low-maintenance, and it convincingly reproduces stone, marble, concrete, and wood. Paired with a professional waterproofing system, proper shower construction, and epoxy grout in wet areas, it looks good on day one and keeps performing for years.

Frequently Asked Questions
What is the best tile for a shower?
Large-format matte or satin porcelain is generally one of the best options because it is durable, non-porous, and low-maintenance. Pair it with epoxy grout and proper waterproofing for the longest life.
Why does marble tile fail in showers?
Marble reacts to acids in many personal care products and needs ongoing sealing. Without it, moisture can get behind the tile and contribute to mold growth.
How much does it cost to replace failed shower tile?
A full shower tear-out and replacement often runs $5,000 to $12,000 or more, depending on materials and how much water damage is behind the walls.
Can glass tile be used in a shower?
Yes, with an experienced installer. Glass tile should generally be avoided on shower floors because of slip concerns.
How much extra tile should I order?
Order 10 to 15 percent more than you need to cover cuts, waste, breakage, and future repairs. Spare tiles from the same production run make future repairs nearly invisible.
What is the difference between cement grout and epoxy grout?
Cement grout is porous and stains more easily. Epoxy grout is non-porous, resists mildew better, and generally performs better in wet areas.
How do I know if my tile installer is doing proper waterproofing?
Ask the installer to explain the waterproofing system. A qualified installer can clearly describe the membrane, the transitions, and the details. If someone says tile and grout alone are waterproof, that is a warning sign.
