In Miami, a shower rarely gets the chance to dry. From mid May to mid October the rainy season keeps the air heavy. A windowless bath in a Brickell tower, or a 1920s Coral Gables bath with one small casement, can stay damp for hours after every use.
I have spent 30 years choosing bathroom tile for humid homes, most of them now at our Miami tile showroom. The lesson never changes: mildew lives in grout and porous surfaces, so the tile decides how hard you will fight it. These are the bathroom tiles for humid homes I trust most.
Best Bathroom Tiles for Humid Homes

Large Format Porcelain: Mildew Resistant Shower Tile With Fewer Grout Lines
Clients usually think mildew grows on the tile, but it actually grows in the grout between tiles. Large format porcelain tile on shower walls cuts the number of joints dramatically, and the porcelain itself absorbs almost no water.
In a windowless condo bath, a 24×48 wall leaves mildew very little to hold on to. A squeegee after each shower does most of the cleaning.

Hand Painted Glazed Ceramic: A Non Porous Tile for Shower Walls With Heritage
A fired glaze is one of the oldest moisture barriers in architecture, which is why Portuguese and Dutch bathrooms have worn painted tile for centuries.
Our hand painted tiles and Royal Makkum Delft bring that tradition to a shower wall that wipes clean in seconds. I like a band of Miradouro azulejos at eye level, framed by plain field tile so the grout count stays low.

Porcelain Slabs: The Most Low Maintenance Bathroom Tile
When someone asks for the lowest maintenance bathroom tile, my answer is a slab. Porcelain slabs can wrap an entire shower in a handful of pieces, leaving only a few vertical joints.
Most suppliers quote slabs on price alone. We measure the shower first, because the joint layout decides whether mildew ever gets a foothold.

Matte Porcelain: The Best Shower Floor Tile for Humid Climates
The shower floor stays wet longest, so it needs grip and density at the same time. A matte or lightly textured porcelain from our shower floor tiles collection gives traction without the open pores of unsealed stone.
Ask for the tile’s wet DCOF rating before you commit. A polished finish that looks stunning in a showroom feels very different under a wet foot.

Mosaics: Easy to Clean Shower Tile When the Slope Is Right
Small mosaics follow the slope to the drain better than any large tile. That matters, because standing water is where shower grout mold starts. The most common mistake we see is a beautiful mosaic floor set too flat, so water lingers in the joints for hours. Get the pitch right, choose a dense body, and finish it with epoxy grout.

Zellige: Is It Good for Showers in Humid Climates?
I would never talk a client out of zellige tile. A hand cut Moroccan glaze catches Miami light like nothing else. But its surface is uneven and its clay body is porous, so it needs a penetrating sealer before grouting and again every year in a busy shower.
On a vanity wall or in a well ventilated shower, it is worth every minute. Its handmade glaze sheds water well, but the wider, irregular grout joints need proper sealing, which is the main factor in whether zellige tile works in a shower over the long run.

Glazed Terracotta: The Best Tile for Humid Bathroom Walls Outside the Spray Zone
Glazed terracotta tile brings the warmth of a Mediterranean Revival house into the bath, and in Coral Gables that warmth belongs. Keep it where water splashes but never sits: a vanity backsplash, a wainscot, the wall behind a tub. Inside the steady spray, I let porcelain do the hard work and save handmade clay for where it can be admired.

Best Grout for Humid Bathrooms: Epoxy vs Cement
Clients often assume a better tile solves everything, but grout is where this battle is won or lost. Cement grout is porous and needs regular sealing.
Epoxy grout resists moisture and staining far better, which is why I specify it in nearly every Miami shower. Choose a mid tone color too: bright white grout in a humid bath shows the first shadow of mildew within a season.

Why Does My Shower Never Dry? A Miami Answer
In a Miami summer, the outside air can be nearly as damp as the shower, so opening a window often helps less than people expect. Run the exhaust fan for at least 20 minutes after every shower, leave the glass door open, and let the AC pull moisture from the air.
In older Miami Beach Art Deco apartments, check that the fan actually vents outdoors and not into the ceiling.

FAQ
What is the best tile for a bathroom with no window?
Large format porcelain or porcelain slabs set with epoxy grout are the best tile for a bathroom with no window, because they leave the fewest grout lines for mildew to grow in.
How do I stop mildew in shower grout?
To stop mildew in shower grout, use epoxy grout in a mid tone color, slope the shower floor toward the drain, and run the exhaust fan for at least 20 minutes after every shower.
Can I use handmade tile in a humid bathroom?
Yes, glazed handmade tiles like hand painted ceramic and zellige work in a humid bathroom as long as porous pieces are sealed and the room is well ventilated.
