10 real before & afters
Neither of these bathrooms was a master bathroom to begin with. A yellow three-piece with a curtain rod and a beige tiled one with an oak vanity — remodelled ten ways: wet room, spa, dark walnut, hotel white, zellige and oak, sage green, classic marble, and two refreshes that leave the tile alone. Then try one on your own bathroom.

What makes it work
It is not the square footage. Separate the tub from the shower, give the vanity two sinks or one long one, use fewer and bigger surfaces, and light the mirror from the sides. Every render below follows those four rules; that is why two ordinary three-piece bathrooms read as the master.
The single change that turns a family bathroom into a master bathroom. A tub-shower with a curtain or sliding doors is what every before photo on this page has; a freestanding tub beside a glass walk-in shower is what most of the renders have. It does not need more floor than you think: the spa renders put both in the footprint the old tub-shower took.
A double vanity is what "master bathroom remodel" means to most people searching it. Where the wall allows it, two undermount sinks in one floating vanity. Where it does not, a single wide trough basin on a long vanity reads the same way. Either way the mirror gets bigger, and the light moves to the sides of it.
Large-format tile, a stone or quartz top, a frameless glass screen. The beige bathroom before photo is a grid of small square tiles floor to ceiling, and every render that reads as expensive replaces it with something larger. Fewer grout lines is most of what "spa" means.
One bar of bulbs above the mirror is the tell of a bathroom that came with the house. Sconces at face height either side of the mirror, or a backlit mirror, plus a warm colour temperature. The renders all do this, and it is the cheapest of the four decisions.
Before and after
Nothing on this page is a stock photo of somebody's finished master bathroom. These are two ordinary bathrooms photographed as they were, and every image below is one of them with a sentence rendered into it. Drag the handles.
Ten master bathrooms
The full remodels first, then the ones that change the surfaces, then the two refreshes that leave the tile where it is. Under each render is the exact sentence that produced it — steal it, change a word, and run it on your own bathroom.
The beige tiled bathroom Full remodel What changed Everything but the window. The beige squares became large-format grey stone on every surface, the tub-shower and its sliding doors became a freestanding tub with an open rain shower beside it behind one glass panel, and the oak vanity became a floating oak double vanity with two vessel basins, two black-rimmed round mirrors and black taps.
Why it works The full master-bathroom answer in one image: tub and shower separated, two sinks, one big surface, one metal. Grey stone in large format is what makes the room look twice the size of the before photo, because the grout grid is gone. The open shower with a single panel is the wet-room trick: no door, no frame, nothing to clean.
“Remodel this bathroom into a wet-room-style master bathroom: large-format grey stone tile on every wall and the floor, a freestanding white tub and an open walk-in shower with a rain head behind a single glass panel where the tub-shower is, a floating oak double vanity with two round mirrors and matte black fixtures. Keep the window where it is.”
The beige tiled bathroom Full remodel What changed The tub-shower became a freestanding oval tub with a frameless glass shower beside it, the oak vanity became a long floating white double vanity with two brass-framed round mirrors and brass sconces, and every fixture went brass. The engine kept the square tile and lightened it to warm white rather than going large-format, so the grid is still there, paler.
Why it works The layout most people mean by "master bathroom remodel": the alcove the tub-shower sat in now holds a freestanding tub, and the shower stands beside it behind glass. Two round mirrors over two sinks with sconces between them is the hotel formula and it works at any budget. Compare with the wet-room render to see what large-format tile adds on top.
“Remodel this bathroom into a spa-style master bathroom: large-format warm white porcelain tile on the walls and floor, a freestanding white oval tub where the tub-shower is, a frameless glass walk-in shower beside it, a floating white oak double vanity with two round mirrors, brushed brass fixtures and warm wall sconces. Keep the window where it is.”
The beige tiled bathroom Full remodel What changed Walls to large-format charcoal, floor to pale wood-look plank, the oak vanity to a floating walnut double with a black top and two backlit round mirrors, the sliding doors to a black-framed glass walk-in shower. The tub went with the sliding doors. The window is where it was.
Why it works The render that photographs best and the one that needs the most planning. Backlit mirrors are the whole lighting scheme here and the reason charcoal walls read as calm rather than dark. Walnut is the one warm material and it sits at eye level. The pale floor is not optional: a dark floor under dark walls would close the room.
“Remodel this bathroom into a moody master bathroom: dark charcoal large-format tile on the walls, a warm walnut floating double vanity with a black stone top, two backlit round mirrors, matte black fixtures, a black-framed glass walk-in shower instead of the sliding doors, and a light wood-look floor. Keep the window where it is.”
The yellow three-piece Full remodel What changed The yellow walls became sage green vertical tile, the floor became terrazzo, the vanity became white oak with a white top and an arched brass mirror, the light bar became a single brass fitting, and a frameless glass screen replaced the curtain rod on the tub. The window, the tub, the toilet and the door are exactly where they were.
Why it works The one colour render on the page and the one that proves a master bathroom does not have to be white. Vertical tile makes the ceiling look higher in a narrow room. Green with oak and brass is warm without being beige. The glass screen on the existing tub is the cheapest way to get the "separate shower" look without moving a pipe.
“Remodel this bathroom into a master bathroom with sage green vertical tile on the walls, a white oak vanity with a white top and an arched mirror, brushed brass fixtures, a white tub with a frameless glass screen, and a white and grey terrazzo floor. Keep the window, tub and toilet where they are.”
The yellow three-piece Full remodel What changed Walls to matte charcoal tile, floor to pale wood-look plank, the vanity to a floating walnut unit with a black vessel basin and a backlit round mirror, the curtain rod to a black-framed glass screen, and a black ceiling light. The window, tub, toilet and door stayed put.
Why it works The same dark idea as the beige bathroom, in a room half the width, and it still works because the floor is pale and the mirror is lit. This is the render to look at if you have a narrow three-piece and assume dark is off the table. The black basin on walnut is the one piece of drama; everything else is quiet.
“Remodel this bathroom into a moody master bathroom: matte charcoal tile on the walls, a walnut floating vanity with a black stone basin, a backlit round mirror, matte black fixtures, a black-framed glass screen on the tub and a pale wood-look floor. Keep the window, tub and toilet where they are.”
The beige tiled bathroom Full remodel What changed The beige squares went white with a grey border line, the oak vanity became a long floating grey vanity with two white vessel sinks and one wide backlit mirror, the sliding doors became a frameless glass shower with a rain head and a heated towel rail beside it, and all the metal went chrome. The engine kept the square tile format and the window.
Why it works The version that reads clean rather than styled, and the safest one to sell a house with. One wide lit mirror instead of two round ones gives the vanity wall a single horizontal line. Chrome is the right metal for it; brass would make it a different room. If you want a master bathroom that will not date, this is the one.
“Remodel this bathroom into a hotel-style master bathroom: white large-format tile with a slim grey border, a long floating grey vanity with two undermount sinks and a single wide mirror with a lit frame, a frameless glass shower with a rain head instead of the sliding doors, chrome fixtures and a white heated towel rail. Keep the window and layout where they are.”
The beige tiled bathroom New surfaces What changed The beige squares became handmade-looking white zellige, the floor became terrazzo, the oak vanity became a lighter oak double with a white top, two arched brass mirrors and brass sconces, and the sliding doors became a single glass screen on the tub. The tub and the window are where they were.
Why it works The render that looks the most like a magazine and costs the least of the full remodels, because the tub did not move. Zellige is glazed by hand so every tile is a different white, which is why the wall reads as textured rather than tiled. Arched mirrors over a double vanity are the shape of the moment; round would date slower.
“Remodel this bathroom into a warm modern master bathroom: white zellige tile on the walls, a natural white oak double vanity with a white stone top, two arched mirrors, brushed brass fixtures, a terrazzo tile floor and a frameless glass walk-in shower instead of the sliding doors. Keep the window and tub position where they are.”
The yellow three-piece New surfaces What changed The tub alcove became marble, the floor became marble, the yellow walls became white beadboard wainscoting with pale grey above, the vanity became white shaker with a marble top and a gold-framed mirror, the fixtures went brass and a glass screen replaced the curtain rod. The three-bulb light bar stayed, reframed in gold. The window, tub and toilet did not move.
Why it works The traditional master bathroom, and the one that suits an older house. Wainscoting is the cheap half of this render: it covers yellow walls for a few hundred dollars and tiles only the wet zone. Marble around the tub and on the floor is where the money goes, and it is the surface that still looks right in thirty years.
“Remodel this bathroom into a classic master bathroom: white marble tile with grey veining on the floor and around the tub, white wainscoting on the walls, a white vanity with a marble top and a brass-framed mirror, polished brass fixtures and a frameless glass screen on the tub. Keep the window, tub and toilet where they are.”
The beige tiled bathroom Fittings and vanity What changed The beige tile went white on the walls, the oak vanity became a white shaker double with a quartz top, one wide black-framed mirror and a black light bar, and every fixture went matte black. The sliding doors came off and the engine left the tub open rather than adding the black-framed panel it was asked for. The floor tile, the tub and the window are the originals.
Why it works The most useful render on the page for most people: the tile you hate, painted, with a double vanity in front of it. Tile paint on walls holds up; on floors it does not, which is why the floor stayed. Everything here is a weekend and a plumber for the faucets. Add the glass panel the engine skipped and this is a master bathroom for the price of a vanity.
“Keep this bathroom's tile and layout but refresh it: paint the beige tile walls white, replace the oak vanity with a white shaker double-sink vanity with a white quartz top, a large black-framed mirror, matte black faucets and light fittings, and replace the sliding shower doors with a single black-framed glass panel. Keep the window, tub and floor exactly where they are.”
The yellow three-piece Fittings and vanity What changed The yellow walls went soft white, the vanity became a white shaker unit with a stone top rather than the oak that was asked for, a round black-framed mirror and a black faucet went in, a black-framed glass panel replaced the curtain rod and the floor became grey wood-look plank. The three-bulb light bar stayed, in black. The window, tub and toilet did not move.
Why it works The render to look at first, because it is the cheapest full-looking change on the page. Paint, a vanity, a mirror, a faucet and a glass panel, and the room reads as new. The floor is the only tiling job and it is a small one. If the three-piece is all the master bathroom you have, this is how far it goes without a builder.
“Keep this bathroom's layout but refresh it into a modern master bathroom: paint the walls soft white, replace the vanity with a white oak vanity with a white stone top, a round black-framed mirror, a matte black faucet and light fitting, a black-framed glass panel instead of the shower curtain rod, and grey wood-look floor tile. Keep the window, tub and toilet exactly where they are.”
The portrait renders are the yellow bathroom, shot from its doorway; the landscape ones are the beige bathroom. Two of the twelve we made were dropped: a marble version kept the old sliding shower doors it was told to replace, and a spa version of the yellow bathroom deleted the toilet it was told to keep. The ten here are as they came off the same engine the free tier of AI Bathroom Design runs on, unretouched.
Where to start
In order of change-per-dollar. A master bathroom remodel is the most expensive room per square foot in the house, so the order matters. Nobody should start at step four without having rendered steps one to three on their own bathroom.
A new faucet, a matching shower head, a framed mirror and sconces beside it in one finish. The refresh renders on both bathrooms are mostly this plus a vanity, and they read as a different room. No tiler, a plumber for an hour.
A few hundred to low four figuresA floating vanity in oak, walnut or painted shaker with a stone top, and two sinks if the wall is wide enough. It sits at eye level in the mirror, so it does more for the room than any tile decision. Keep the plumbing where it is and the job stays a day.
Low to mid four figuresSliding doors or a curtain rod out, a single frameless or black-framed glass panel in. This one change makes the beige bathroom renders look twice their size, because you can see the whole room again.
Low four figuresA freestanding tub, a walk-in shower, large-format tile on the walls and floor. This is the full master bathroom remodel and the only step here that needs permits and weeks. Render it three ways before you commit: the spa, marble, dark and wet-room versions on this page were all made on the same two bathrooms for that reason.
Mid to high five figuresWhat goes wrong
The mistakes are expensive because they are tiled in. Each of these is a real, common one, and each is avoidable at the render stage for free.
A freestanding tub wedged into an alcove is a built-in tub that is harder to clean. If the room only has an alcove, keep an alcove tub with a good front panel and spend the money on the shower instead. The spa renders here put the tub where there is floor on three sides.
The beige before photo is the cautionary tale: a grid of four-inch squares from floor to ceiling. Grout lines make a room busy and small. Large-format on the walls and floor, and if you want small tile, one wall or the shower floor only.
A chrome faucet, a brass mirror and black light fittings read as three separate purchases. Pick one finish — brass, black or chrome — and use it on everything, including the shower frame and the towel rail. Every render here uses one.
Both real bathrooms have a window, and the renders that read best keep it bare and let it light the tub. Do not tile over it, box it into a shower without a frosted panel, or hang a heavy blind. Master bathrooms are the one room where daylight is a luxury you already own.
Questions
Size helps but is not the definition. It is the bathroom attached to the main bedroom, and what people mean by the phrase is a set of features: two sinks or a long vanity, a shower separate from the tub, better light and better surfaces than the family bathroom. Both real bathrooms on this page are ordinary three-piece rooms, and the renders add those features inside the footprint they already have.
A refresh — fixtures, mirror, lights and a vanity on the existing tile — is low to mid four figures and needs no tiler. Adding a glass screen and retiling one wall is mid four figures. A full remodel with a freestanding tub, walk-in shower, new tile throughout and a double vanity is mid to high five figures depending on where you live and whether plumbing moves. The renders are labelled by which of those they are.
Usually, if you give up the tub-shower combination. The alcove a standard tub-shower sits in is five feet wide and about thirty inches deep. A compact freestanding tub is around fifty-five inches long, and a walk-in shower needs about thirty-two inches square. Side by side they need more width than the alcove has, so the shower usually goes where the vanity or the toilet was and the layout shifts. The spa and wet-room renders show the version where the tub takes the alcove and the shower stands beside it behind a single glass panel.
Double if the wall is sixty inches or wider, single if it is not. A double vanity on a forty-eight-inch wall gives you two sinks and no counter, which is worse than one sink with counter either side. The beige bathroom has the width and the renders give it two round mirrors over two sinks; the yellow bathroom does not and gets one wide vanity and one big mirror.
Warm white, greige, or stone for the surfaces, one warm metal for the fittings, and one darker material for depth: walnut, charcoal or a dark floor. The spa and marble renders are the light version; the dark renders on both bathrooms are the moody version with a walnut vanity and charcoal tile. Sage green on the yellow bathroom is the one colour render here, and it works because everything else in that render is white and oak.
Keep one tub in the house for resale, and it does not have to be this one. If the family bathroom has a tub, the master can be a large walk-in shower and nothing else, which is the best use of a small master bathroom. If this is the only tub, keep it and separate it from the shower if the width allows.
That is what the upload box at the top of the page is for. Photograph the bathroom from the doorway, type one of the sentences under the renders — or your own — and you get the render back in about ten seconds. Every image on this page was made exactly that way, on two ordinary bathrooms, and the sentence under each render is the one that produced it.
Photograph it from the doorway, pick the sentence you kept scrolling back to, and you will have it rendered onto your own bathroom in about ten seconds. Free, on iPhone, Android and the web.
