The grout along the bottom two rows of my last shower went grey and stayed grey, and I blamed the cleaner for about a year before I worked out it was the fan, which was original to the house and moved roughly as much air as a person breathing on it. That’s why my bathroom design ideas now start with the boring machinery and work outward to the nice bits, because the pretty stuff only stays pretty in a room that dries out properly between showers.
Twelve things below. They’re numbered so you can skip to whichever one your room needs.
The fan is the first thing I’d replace
Moisture is what wrecks a bathroom, and it doesn’t announce itself; it just sits there, darkening the grout and swelling the bottom edge of the vanity until one day you notice the paint has slightly bubbled near the ceiling.
The Home Ventilating Institute’s bathroom ventilation guidance puts it at one CFM per square foot of floor for rooms up to a hundred square feet, and fifty CFM as the floor for anything small. So a seven-by-ten room wants 70, not the 50 that got put in when the house was built. Bigger than a hundred square feet, and you count fixtures instead, about fifty each for the toilet, the shower and the tub, which adds up faster than people expect.
- Size the fan to the room. Write the square footage on your hand before you go to the shop, because every box on that shelf claims to be enough.
- Put it on a timer so it keeps running twenty to thirty minutes after the water stops. Left to a switch, it never happens; I’ve never met a household that remembers, mine included.
Light at face height changes more than paint does
One fixture in the middle of the ceiling puts your whole face in shadow, which is why so many bathrooms are horrible to shave in even though the room is technically bright. You want the light coming at you sideways, not from above.
- Sconces on both sides of the mirror, roughly eye level, with warm bulbs in the 2700K to 3000K range so skin doesn’t go grey and sickly under them.
- A dimmer on the ceiling light. It costs almost nothing, and it lets the same room feel like seven in the morning and eleven at night.
If there’s no wiring for sconces and you’re not opening walls to get it, an LED strip tucked behind the mirror gets you some of the way. Not all of it. It’s still better than the shadow.
Mirrors and a vanity that lets you see the floor
- Go bigger on the mirror than feels sensible. Wall to wall if the wiring lets you get away with it. A plain frameless sheet cut by a glass shop usually costs less than the framed one in the bathroom aisle, and secondhand ones turn up constantly. However, I’d give any old mirror the same going-over I’d give a chair: the same four-second check I use on everything else I buy from a thrift store.
- A floating vanity. Seeing the tile run underneath it makes the room read bigger than it is, and it’s far easier to mop under, which sounds trivial until you’ve lived with a cabinet sitting flat on the floor collecting a fur of dust along the kickboard.
Most bathroom design ideas skip the walkway, and then the room feels wrong.
This is the part people leave until the end, and it’s why a bathroom full of nice pieces can still feel like a cupboard.
Code wants at least twenty-one inches of clear floor in front of the toilet, sink and tub, and twenty-four in front of a shower entry. The National Kitchen and Bath Association recommends thirty. That gap between twenty-one and thirty is the whole difference between walking through a room and shuffling sideways through it with your elbows in.
- Buy the vanity that protects the walkway, not the one that fills the wall. A twenty-four-inch vanity with room to stand beats a thirty-six-inch one you have to edge past, and the storage you gave up can go up the wall over the toilet where it was never in your way anyway.
- Hang the door to swing outward, or fit a pocket door. In a tight room, this gives you more usable floor than any layout trick I know of, and it’s a fraction of the cost of moving a single pipe.
Floors, and the grout argument I keep having
- Run the same tile out through the doorway if the hallway lets you. Stopping the floor at a threshold cuts the space into two smaller rooms in your head, and your head is doing most of the work here.
- Fewer grout lines, grout colored close to the tile. Big format tile with matched grout reads as one quiet surface. Contrast grout is a real look, and I’ve used it; it just draws a grid across your floor, and a grid on a small floor makes the floor look smaller. Whether that trade is worth it depends on how much you like the look, and some days I’m not sure.
Storage, so the floor stays empty
- A recessed niche in the shower wall, framed in while the wall is open, which costs very little at that stage and gets rid of the hanging caddy that rusts and drops a shampoo bottle on your foot every eight months or so. While you’re planning the cabinet, drawers beat doors for the same reason a drawer beats a deep cupboard anywhere else: things at the back of a cupboard are gone.
- Hooks, and more of them than seems reasonable. A bar holds one towel properly and two towels badly, so towels stay damp and the room starts to smell like a wet room instead of a bathroom.
Let one surface be loud.
Everything above is structural. This bit is taste, so hold it loosely.
The rooms I like usually have one thing doing the talking. A patterned floor under plain walls, or a painted ceiling, which is a slightly strange move that keeps working on me. What falls over is the feature wall plus the pattern plus a bold vanity plus brass on every fitting, and I say that having done exactly that in a windowless room and then lived with it for two years out of stubbornness rather than any real defense of it.
A plant does more in there than another ornament would, as long as it’s something that tolerates low light and steam, so pothos, most ferns. The pot is doing a good chunk of the work too, which I got into properly in this piece on decorative planters.
If the budget only covers two things
Mirror and fan. That’s an unglamorous answer for a list like this, and I’ll defend it anyway, because the tile is what gets photographed and the ventilation is what decides whether the tile still looks like that in three years. I’ve never once walked into a well-lit bathroom and thought much about the floor.
