Here is how to deep clean a bathroom without wasting effort: open a window, clear everything out, spray the tub and toilet so the cleaner can soak, then work from the top of the room down: fan and lights, mirror and vanity, shower and tub, toilet, and the floor last. Dry surfaces before wet ones, high before low, and you never drip dirt onto something you already cleaned. This guide covers how to deep clean bathroom surfaces from the ceiling fan to the floor, and most bathrooms take one to two hours the first time.

Below: a supplies list, the step-by-step order, a free printable bathroom deep cleaning checklist (PDF), how often to do it, safety mistakes to avoid, and an FAQ. For the quick weekly version, see our weekly house cleaning schedule.

What You Need: Bathroom Deep Cleaning Supplies

You do not need a cabinet full of specialty sprays. Gather everything into one caddy or bucket before you start so you are not walking back and forth with wet gloves.

• An all-purpose cleaner for counters, cabinet fronts, light switches and baseboards.
• A bathroom or tub-and-tile cleaner for soap scum. Read the label for how long it needs to sit and which surfaces it is safe on.
• Toilet bowl cleaner and a toilet brush.
• Glass cleaner (or a mix of water and a little dish soap) for the mirror.
• White vinegar and baking soda for hard-water spots, the showerhead and a gritty paste on grout. Skip vinegar on marble, travertine and other natural stone; it can etch them.
• Microfiber cloths in two colors: one color for the toilet only, the other for everything else.
• A stiff scrub brush, an old toothbrush and a squeegee for grout, faucet bases and glass.
• Rubber gloves, a vacuum or broom, and a mop or a floor cloth.

How to Deep Clean Bathroom Surfaces Step by Step (Top to Bottom)

Follow the steps in this order. The soaking in step 1 is what makes the scrubbing later go fast, so do not skip it.

1. Prep: Ventilate, Clear Out and Let the Cleaner Soak

• Open a window and turn on the exhaust fan. Put on gloves.
• Take everything off the counter, the tub edge, the shower shelves and the floor: toiletries, the trash can, the bath mat, the toilet brush holder.
• Gather towels, the bath mat and a washable shower curtain liner into a tall laundry basket and start a load now, so they are clean and dry when you finish.
• Spray the tub, shower walls and glass with your tub-and-tile cleaner, and squirt toilet bowl cleaner under the rim. Let both sit while you clean higher up.

2. Exhaust Fan, Lights and Ceiling

Dust falls, so start at the top. Switch the fan off, then vacuum the fan grille with a brush attachment or wipe it with a barely damp cloth; many covers pop off for a wash in warm soapy water (dry it fully before you put it back). With the power off and bulbs cool, dust the light fixture. Wipe ceiling corners, the top of the door and the door frame, and spot-clean splashes on the walls.

3. Mirror, Medicine Cabinet and Sink Vanity

• Mirror: spray the cloth, not the mirror, so cleaner does not drip behind the frame. Wipe in an S pattern and buff with a dry microfiber cloth.
• Medicine cabinet and drawers: empty them, toss expired products, wipe the shelves and put back only what you use. The 50-things decluttering checklist has a bathroom list to speed this up.
• Under the sink: wipe the cabinet base, check for drips around the pipes, and let it dry with the door open. If it needs a full reset, follow our guide to organizing under the bathroom sink.
• Sink and faucet: scrub the basin, the overflow hole and around the faucet base with the toothbrush. Pull the drain stopper, clear hair and gunk, and rinse.
• Soap and toothbrushes: a soap dish without drainage leaves a slimy ring every week. If that is your problem spot, a quick-dry sink caddy keeps soap and brushes off the wet counter.

4. How to Deep Clean a Shower and Tub

By now the cleaner has had time to work on soap scum. Go section by section:

• Showerhead: fill a plastic bag with white vinegar, slip it over the head, secure it with a rubber band and leave it for about an hour (check your fixture finish first; skip long soaks on brass or specialty finishes). Remove, run hot water and scrub the nozzles with the toothbrush.
• Tile: scrub walls from the top down with a stiff brush or a non-scratch sponge, then rinse.
• Grout: make a paste of baking soda and water, scrub the lines with the toothbrush and rinse. For dark mildew stains, use a product made for mold and mildew and follow its label. Do not add vinegar or other cleaners to it.
• Glass doors: hard-water film comes off with a vinegar spray or a dedicated glass descaler. Rinse and squeegee dry, then wipe the tracks with the toothbrush and a cloth.
• Tub and drain: scrub the tub, rinse it, and pull hair out of the drain with a plastic drain tool or gloved fingers.
• Shelves and caddies: wash them, and toss empty bottles. Bar soap sitting in a puddle is a common source of soap scum; a draining wall-mounted bar soap holder keeps bars up off the ledge.

5. Toilet

Scrub the bowl, getting under the rim, and flush. Then wipe from cleanest to dirtiest with your toilet-only cloth: tank lid and handle, the tank, the top and underside of the seat, the hinges, the outside of the bowl, and finally the base and the floor around it. An old toothbrush gets into the hinge and bolt-cap gaps. Rinse the toilet brush by trapping it between the seat and the bowl while it drips dry.

6. Floors, Baseboards and Door

Wipe baseboards, the door, the handle and the light switches. Vacuum or sweep corners and behind the toilet, where hair collects. Mop last, working from the far corner toward the door so you do not step on the clean floor. Let it dry.

7. Put Everything Back

Rehang the clean towels, mat and liner. Return only the products you use daily to the counter, and give the rest a home under the sink. If you are short on space, our small bathroom storage ideas without drilling help. Empty the trash and you are done.

How Often Should You Deep Clean a Bathroom?

A good rhythm for most homes: a quick clean of the toilet, sink, mirror and shower once a week, and the full deep clean above about once a month. A few jobs can wait for each season: scrubbing every grout line, washing the fan cover and replacing the shower curtain liner. A shared or kids’ bathroom may need the weekly pass more often. Our 15-minute daily cleaning routine keeps the bathroom from sliding back between deep cleans.

Common Mistakes (and Safety Rules)

• Mixing cleaners. Never mix bleach with ammonia (found in some glass cleaners) or with acids such as vinegar or some toilet bowl cleaners: the combinations release toxic gases. Use one product, rinse well, then switch.
• Cleaning in a closed room. Always open a window or run the fan, and step out if fumes bother you.
• Spraying and wiping straight away. Most bathroom cleaners need a few minutes of contact time; check the label.
• Cleaning bottom to top. Dust and drips land on the floor you already mopped.
• Using one cloth for everything. Keep a separate cloth for the toilet.
• Using vinegar or abrasive powders on stone and specialty finishes. Check what your counter and fixtures are made of first.
• Ignoring large mold patches. Small spots of mildew are a normal cleaning job; a large patch or mold that keeps coming back points to a moisture problem. Tell your landlord if you rent, or get a professional opinion.

FAQ

How long does it take to deep clean a bathroom?

Usually one to two hours for an average bathroom the first time, depending on its size and how much soap scum and hard water has built up. Later monthly deep cleans tend to go faster.

What is the best way to clean shower grout?

Scrub it with a paste of baking soda and water and a stiff toothbrush, then rinse. For mildew stains, use a mold and mildew cleaner as the label directs. Once the grout is clean and fully dry, a grout sealer helps it resist new stains.

Can you mix vinegar and baking soda to clean a bathroom?

You can use them one after the other, for example baking soda paste on grout followed by a vinegar rinse on glass. Mixing them in one bottle mostly cancels them out. Never mix vinegar with bleach.

Should you clean the toilet or the shower first?

Spray both at the start so they can soak, then clean the shower and sink before the toilet. Finishing with the toilet and floor keeps germs and grime from spreading to surfaces you already cleaned.

A Fresh Bathroom in One Afternoon

A deep clean is mostly about order: ventilate, let the cleaner soak, work top to bottom and finish with the floor. Print the bathroom deep cleaning checklist, block out an afternoon once a month, and keep the weekly quick clean going in between.
