Modern Bathroom Ideas: Vanity, Sink, Floor and Shower Plans

A modern bathroom is built from a few materials used in large, simple surfaces: a clean-lined vanity, a large-tile floor, one textured wall, and fixtures from a single metal family. Ornament comes from the materials themselves, such as the veining in a stone sink or the glaze on a handmade tile, more than from trim or pattern. The modern bathroom ideas in this guide are organized as eight decisions, then put together into four complete plans, each built from products you can see and shop.

Most decisions link to a deeper guide in this series, so you can go as far into one part of the room as you need. The plans at the end show how the same decisions produce four distinct palettes.

1. Start with the layout and clearances

Before choosing any finish, the floor plan decides what fits. Two sets of numbers apply. The International Residential Code (IRC), a model code that US jurisdictions adopt with local changes, sets the minimums in sections R307.1 and P2708.1: a toilet centerline at least 15 inches from a wall or another fixture, at least 21 inches of clear space in front of a sink, toilet or tub, 24 inches in front of a shower opening, and a shower interior of at least 30 by 30 inches. The National Kitchen and Bath Association (NKBA) planning guidelines recommend more room for comfort: 18 inches from the toilet centerline, and 30 inches of clear space in front of each fixture. Local codes govern, so the figures for your project come from your building department.

Several modern habits respond to tight clearances. A floating vanity frees floor space that a cabinet on legs would visually fill. A walk-in shower without a curb makes the room look like one floor. A wall-mount faucet leaves more of the counter clear. All three save visual space.

2. The vanity sets the line of the room

The vanity is the largest piece of furniture in most bathrooms, so its shape decides how modern the room feels. A floating vanity mounts to the wall and leaves the floor visible underneath it, which makes a small bathroom look larger and gives the room a long horizontal line. A freestanding vanity on legs or a plinth has the shape of furniture and brings a warmer note. Some cabinets, sold as dual mount, can go either way.

On the left, a 72 inch floating double vanity in chestnut, wide enough for two sinks. On the right, a compact 20 inch floating vanity with a ceramic sink, sized for a powder room or a narrow wall. Single vanities in our range run from about 16 to 72 inches wide, and doubles from 60 to 120 inches. Height is the other number. The 48 inch James Martin Bristol, for example, stands about 32 1/2 inches before its top is added, and a vessel bowl adds its own height above that. Our bathroom vanities cover all of these, and the James Martin cabinets shown here are sold as cabinets, designed for a 3 cm stone top chosen separately.

3. The sink: vessel, undermount or integrated

A modern bathroom can take any of three sink types, and each changes the look of the counter. An undermount sink sits below a stone, quartz or sintered top, so the counter looks like one clean surface. An integrated sink is molded into the top itself, the simplest look of all. A vessel sink sits on top of the counter as a sculptural bowl, and a carved stone vessel brings natural pattern into a room that otherwise has very little.

A vessel bowl rises 4 to 8 inches above the counter, so it pairs with a wall-mount or tall faucet. Our guide to stone vessel sinks compares marble, travertine, onyx and limestone bowls with their sizes and weights, and the full range is in marble sinks.

4. The floor: large tiles, few joints

Large tiles, 12 by 24 inches or bigger, are a hallmark of modern bathroom floors, set with narrow grout joints. Fewer joints make the floor look like one plane, which is the calm background a modern room needs. Matte and honed finishes keep that calm. Stone-look porcelain in limestone, concrete or marble patterns keeps that quiet surface in a dense, uniform material, and natural stone such as honed marble or limestone gives the same calm with real variation from tile to tile. A small mosaic, such as a 2 inch hexagon, is the exception, used as a deliberate pattern. Browse modern bathroom tile in our bathroom tiles.

5. The shower: one texture, one accent

One approach for a modern shower is plain, large tiles on most walls, one textured or patterned surface where the eye lands, and a small mosaic on the floor. The textured surface might be fluted marble, handmade zellige or a herringbone mosaic on the back wall. Our three shower guides go deeper on each part:

• Marble shower ideas for walls, floors and accents in natural marble
• Shower floor tile ideas in pebble, porcelain mosaic and stone
• Shower niche ideas for niche sizes, tile and trim

For layout direction on the walls, see vertical or horizontal shower tile, and for a wider set of shower looks, our walk-in shower tile ideas.

6. Glass that disappears

Frameless tempered glass suits a modern shower, either a fixed panel on a walk-in shower or a sliding or hinged door. With little or no metal around it, the glass almost disappears, and the tile runs visually from the bathroom floor into the shower.

This sliding door uses 5/16 inch tempered glass with a soft-close track. A sliding door suits a shower where a swinging door would hit the vanity or the toilet, which ties back to the clearances in section 1. More styles, including fixed panels and folding doors, are in our shower doors.

7. The tub, if there is one

In a modern bathroom, a freestanding tub works as a piece of sculpture in the room. An acrylic or stone resin tub keeps the weight down, and a tub carved from solid marble or travertine becomes the centerpiece, at roughly 1,000 to 1,400 pounds empty. Our list of marble and stone bathtubs compares ten carved tubs with their sizes and weights, alongside two stone resin options.

8. Mirror and one metal family

Modern bathrooms pair the vanity with a mirror a little narrower than the cabinet, or two mirrors over a double vanity. Sconces on each side of a mirror light the face from the sides, where a single fixture above the mirror can cast shadows under the eyes.

For fixtures, one metal family repeated everywhere makes a bathroom look planned: the faucet, the mirror frame, the shower trim and the cabinet hardware. Matte black is graphic and works with white and gray. Brushed nickel stays quiet and cool. Brass and gold warm a room built on wood, travertine or green tile. Wall-mount faucets come in each finish; see bathroom faucets.

Four modern bathrooms, put together

Each plan below is one bathroom, from vanity to shower wall, with one metal family throughout. Three use a stone vessel sink and one a compact floating vanity with an undermount sink, so you can compare how the materials change the mood.

Warm minimal. A 48 inch walnut vanity in a dual-mount design, which can be wall-mounted as a floating vanity, carries a honed travertine vessel sink on a flat stone top of your choice. Gold and champagne brass stay in one warm metal family on the faucet and the mirror. The floor is a warm sand concrete-look porcelain in 12 by 24 inches, and the shower is lined in Mood Sand, a warm limestone-look porcelain in 12 by 24 inches listed for shower walls. Every material sits in the beige-to-honey range.

Black, white and brass. A 60 inch black vanity with champagne brass hardware and a flat stone top of your choice holds a polished white marble vessel bowl, and the brass repeats on a gold wall-mount faucet and a brass-framed mirror. The marble checker floor in black, white and gray is the one busy surface here, so the shower is kept plain in a 12 by 24 inch polished Carrara. The freestanding vanity adds the shape of furniture to a black and white room.

Soft gray spa. A 36 inch whitewashed oak vanity with satin nickel hardware sets a soft base under a polished Tundra Gray marble bowl, with a brushed nickel wall-mount faucet in the same silver range and a driftwood-framed mirror. The floor is a smoke-gray limestone-look porcelain, and the shower uses a honed gray marble-look subway in 4 by 12 inches. Gray stays dominant, and the wood keeps it from turning cold. A honed Tundra Gray tub from our stone bathtubs list would complete it.

Small and modern. For a powder room or a small bath, a 29.9 inch floating vanity with a sintered stone top and undermount sink keeps the floor clear. A matte black faucet and a 24 inch matte black mirror match each other. The white matte 2 inch hexagon floor keeps the small room light, and a green glossy zellige in the shower is the single color.

From modern to other styles

The same eight decisions apply to any style and to any modern bathroom remodel; only the materials change. A modern farmhouse bathroom swaps the floating vanity for a furniture-style cabinet and adds subway tile and travertine, as in our modern farmhouse bathroom plan. A spa-style master bath centers on a stone tub and a double vanity, covered in master bathroom ideas. A Japanese-Scandinavian look built on pale wood and stone basins is in our Japandi bathroom guide.

Modern Bathroom FAQ

What is the difference between modern and contemporary bathroom design?

Modern design refers to a specific style rooted in mid-20th-century modernism: clean lines, little ornament, natural materials and a focus on function. Contemporary design means whatever is current, so it changes over time and can borrow from many styles. In bathrooms the two overlap today, and the modern bathroom ideas in this guide follow the modernist principles of few materials and simple forms.

Is marble modern or traditional?

Both, depending on how it is used. Polished marble with ornate trim and small patterns looks traditional. Honed marble in large formats, a carved marble vessel bowl or a fluted marble wall looks modern. The material is the same; the format, finish and amount of decoration around it decide the style, and a modern room can hold marble in one place, such as the sink or the shower.

Can a small bathroom be modern?

Yes, and the style suits small rooms. A floating vanity shows the floor beneath it, a large floor tile has fewer joints to break up a small area, frameless glass keeps the shower open to the room, and a wall-mount faucet frees the counter. The fourth plan above is sized for a small bathroom, with a 29.9 inch floating vanity.

How do you add warmth to a modern bathroom?

Through materials more than color. Wood vanities in walnut or oak, a travertine or limestone sink, a warm-toned floor such as a sand concrete-look porcelain, and brass or gold fixtures all bring warmth while keeping the simple lines. The warm minimal plan above uses all four.

What size floor tile suits a modern bathroom?

Large tiles, around 12 by 24 inches and up, give the long, quiet surface a modern room is built on, because fewer joints break up the floor. Squares of 24 by 24 inches work the same way. Small mosaics, such as 2 inch hexagons, are used where a pattern is wanted, as in the small bathroom plan above, or on a shower floor.

What size shower fits a modern bathroom?

The International Residential Code sets a 30 by 30 inch shower interior as the minimum, and designers plan for more, around 36 by 36 inches, for comfort. Walk-in showers of 36 by 48 inches or larger take a fixed glass panel without a door. A larger shower has room for a niche, a bench or a second shower head.
