Bathrooms are small rooms with a lot of surfaces, which is why they're the room people most often clean inefficiently. Cleaner gets sprayed, wiped off before it has done anything, and the same square metre gets touched three times.
There is a sequence that fixes this, and it's the one professional cleaners use. It has three rules: dry work before wet work, top before bottom, and the toilet last. Follow it and a weekly bathroom clean takes about fifteen minutes.
Quick Answer: Clear the surfaces and sweep the floor first. Spray the shower, bath and basin and leave the product to dwell while you do mirrors and dust. Then scrub in the same order you sprayed, working top to bottom. Clean the toilet last with dedicated cloths, mop out of the room, and finish by squeegeeing the shower glass dry.
The Three Rules That Save the Time
Dry work before wet work. Sweep or vacuum the floor, clear the vanity, and dust the exhaust fan grille before anything gets wet. Dust plus water equals mud, and once you have made mud you have doubled the job.
Top to bottom. Gravity is on your side exactly once in this room. Everything you dislodge from a shelf or a shower wall lands lower down, so clean the highest surface first and the floor last.
Dwell time is not optional. Bathroom cleaners work by chemistry, not by pressure. CHOICE Australia's lab testing of bathroom cleaners tests products against real soap scum, and dwell time is what separates a product that works from one that doesn't. Spraying and immediately wiping is the single most common mistake in this room — you're doing all the work the chemical was going to do for you.
What You'll Need
Three microfibre cloths in different colours — one for the toilet, one for the basin and taps, one for glass and mirrors. Colour-coding prevents the one genuinely unhygienic mistake in bathroom cleaning.
A toilet brush
A stiff nylon grout brush
A rubber squeegee
A bathroom cleaner (or a pH-neutral cleaner if your tiles are natural stone)
Glass cleaner or a dedicated glass microfibre cloth
A mop or floor cloth
Rubber gloves
⚠️ Safety note: Never mix bleach with vinegar, ammonia or any acidic cleaner — the Washington State Department of Health treats the chlorine gas this releases as a genuine household poisoning risk. Use one product, rinse, ventilate, then use another if you need to.
How to Clean a Bathroom, In Order
Step 1: Clear and Dry-Clean (3 minutes)
Take everything off the vanity, the shower shelf and the windowsill and put it outside the room. You cannot clean around objects, only between them.
Bin what's empty. Then sweep or vacuum the floor, including behind the toilet and along the skirting, and run a dry cloth or the vacuum brush over the exhaust fan grille — it collects a felt of dust that recirculates every time the fan runs.
Step 2: Spray and Walk Away (30 seconds, then wait)
Spray the shower walls, the screen, the bath and the basin. Then leave them.
This is the step that changes how long the job takes. While the product dwells, you have three or four minutes of useful work to do elsewhere in the room.
Step 3: Mirrors and Glass (2 minutes)
Do the mirror while the sprays are working. A damp microfibre cloth followed immediately by a dry one beats glass cleaner and paper towel, and leaves nothing to streak.
Wipe the light switch, the door handle and the towel rail while you're at eye level.
Step 4: Shower and Bath (5 minutes)
Come back to the surfaces you sprayed and work them in the same order.
Walls first, then the screen, then the bath, then the shower floor. Use the grout brush along the tile joints and around the drain rather than a cloth — a cloth skates over a grout line without ever entering it.
If the glass is cloudy rather than dirty, that's mineral scale, and it needs the soap scum and hard water treatment rather than more scrubbing. Blocked or spotty shower head? That's its own quick job, and worth doing while everything else dwells.
Rinse everything down and squeegee the screen.
Step 5: Basin, Taps and Vanity (3 minutes)
Basin bowl, then the rim, then the taps, then the vanity top, then the cupboard doors and handles.
Chrome tapware wants a damp cloth and a dry buff, not an abrasive — chrome scratches easily and once it's scratched it holds water spots permanently. Get into the join where the tap meets the basin with an old toothbrush; that seam holds more grime than the whole rest of the vanity.
Step 6: The Toilet, Last (3 minutes)
Last, always, and with cloths that never touch anything else.
Squirt cleaner under the rim and leave it while you do the outside.
Wipe the cistern, the lid, the seat (both faces), the hinges and the pedestal, working top down.
Do the floor immediately around the base — this is where odour actually comes from in most bathrooms, not from the bowl.
Brush the bowl, under the rim and down into the trap.
Rest the brush under the closed seat to drip into the bowl for a minute before putting it back in its holder.
Step 7: Floor, and Out (2 minutes)
Mop from the far corner back towards the door so you walk out over clean, drying floor rather than across it.
Put the vanity items back — wiping the base of each bottle as it goes back, which takes ten seconds and stops the ring marks. Fresh towels on the rail, bin liner replaced, exhaust fan on.
The Monthly Deep Clean
Everything above is the weekly pass. Once a month, add:
Grout. A proper grout clean with bicarb and a stiff brush, joints only, and re-seal annually.
Shower head. Descale it — mineral buildup narrows the jets and weakens the spray long before you notice.
Drains. Pull the hair out of the shower and basin traps. This is unpleasant and it prevents the two most common bathroom plumbing calls.
Exhaust fan cover. Most unclip. Wash the cover in soapy water, dry it fully, and put it back.
Behind and under. Move the bin, the scales and the vanity stool; clean the floor beneath and the skirting behind the door.
Cabinet interiors. Wipe out the vanity drawers and bin expired sunscreen and medication.
Silicone seals. Check the bead where the bath meets the tile. Blackened or lifting silicone needs replacing, not cleaning.
Keeping a Bathroom Clean Between Cleans
The bathroom rewards small habits more than any other room, because everything that makes it dirty is water that hasn't dried.
Squeegee the shower screen after the last shower of the morning. Thirty seconds, and it prevents most soap scum and most glass scale.
Run the exhaust fan for twenty minutes after showering, not just during. That last twenty minutes is when the room actually dries — and it's the single most effective thing you can do about mould. CSIRO scientist Anthony Wright frames indoor mould as a moisture problem first, a cleaning problem second.
Wipe the basin after brushing teeth. Ten seconds.
Hang towels spread out, not folded, so they dry properly and don't go musty.
Close the toilet lid before flushing. It keeps aerosolised bowl water off your toothbrush.
How Often to Clean a Bathroom
Task | Frequency |
|---|---|
Squeegee shower screen | Daily |
Wipe basin and taps | Every 2–3 days |
Full weekly clean (steps 1–7) | Weekly |
Toilet | Weekly, or twice weekly in a busy household |
Grout and shower head | Monthly |
Drains and exhaust fan | Monthly |
Grout sealing | Annually |
Silicone check | Annually |
A single-person bathroom can stretch the weekly clean to fortnightly. A family bathroom with a shared shower generally can't.
Frequently Asked Questions
Q: What order should I clean a bathroom in?
Dry work first (clear surfaces, sweep, dust the fan), then spray the shower, bath and basin and let the product dwell while you do mirrors. Then scrub top to bottom — shower, bath, basin, vanity — and clean the toilet last with dedicated cloths. Mop out of the room.
Q: How long should cleaning a bathroom take?
About fifteen minutes weekly for a standard bathroom, once you're working in a fixed order. A monthly deep clean, including grout, drains and the exhaust fan, takes closer to forty-five.
Q: Why should the toilet be cleaned last?
To keep cloths and brushes that have touched the toilet away from everything else, and because cleaning it first means walking past a wet toilet for the rest of the job. Use a colour-coded cloth that never touches another surface.
Q: What's the fastest way to clean a bathroom?
Spray everything that needs to dwell in the first thirty seconds, then use the waiting time productively on mirrors and dusting. Almost all wasted time in this room is spent scrubbing surfaces that a chemical would have cleaned on its own with four minutes of contact.
Q: How do I clean a bathroom without harsh chemicals?
Most bathroom soil is soap scum and body oil, which a pH-neutral cleaner and a microfibre cloth handle well given dwell time. Bicarb paste handles grout and the bath. Save stronger products for visible mould, and if your tiles are natural stone, avoid acids entirely — they etch the stone.
Q: How often should a bathroom be deep cleaned?
Monthly for grout, drains, the exhaust fan and behind the fixtures. Annually for grout sealing and a silicone inspection. The weekly clean handles everything else.
