How to Deep Clean a Bathroom (Complete Room-by-Room Guide)

A bathroom deep clean covers every surface from ceiling to floor — including areas that regular weekly cleaning misses. Here's a complete, efficient guide to deep cleaning your entire bathroom in the right order.

What You'll Need

• Scrubbing Bubbles Mega Bathroom Cleaner
• Lysol Toilet Bowl Cleaner Gel
• Bar Keepers Friend Soft Cleanser
• RMR-86 Mold and Mildew Stain Remover
• Foxtrot Living Grout Brush
• OXO Good Grips Toilet Brush
• Amazon Basics Non-Scratch Sponges
• Microfiber Cleaning Cloths
• Drain Snake
• White vinegar, baking soda, rubber gloves

The Golden Rule: Top to Bottom, Dry to Wet

Always clean from top to bottom so dust and debris fall onto surfaces you haven't cleaned yet. Clean dry surfaces (ceiling, walls, cabinets) before wet surfaces (toilet, sink, tub, floor).

Step-by-Step Deep Clean Order

1. Ventilate and Prep

Open the window and run the exhaust fan. Remove all items from counters, shelves, and the shower. Take out bath mats and towels for washing.

2. Apply Toilet Bowl Cleaner First

Apply Lysol Toilet Bowl Cleaner Gel under the rim and let it soak while you clean everything else. This maximizes contact time with minimal effort.

3. Treat Mold and Grout

Spray RMR-86 on any mold stains on the ceiling, walls, or grout. Let sit while you continue cleaning.

4. Clean the Ceiling and Walls

Wipe the ceiling with a damp microfiber cloth. Spray Scrubbing Bubbles on tile walls and let sit 5–10 minutes.

5. Clean the Shower and Tub

Scrub tile walls with a non-scratch sponge. Scrub grout lines with the grout brush. Clean the shower head, faucet, and fixtures. Scrub the tub with Bar Keepers Friend.

6. Clean the Sink and Faucet

Scrub the sink with Bar Keepers Friend. Clean the faucet with vinegar. Scrub around the drain with a toothbrush. Flush the drain with baking soda and vinegar.

7. Clean the Mirror and Cabinet

Spray mirror with vinegar solution and wipe with microfiber cloth. Wipe cabinet exterior and interior shelves.

8. Scrub the Toilet

Scrub the bowl with the toilet brush. Wipe the exterior — tank, lid, seat (top and bottom), bowl exterior, and base — with disinfectant spray and microfiber cloth.

9. Clean the Floor

Sweep or vacuum, then mop. Scrub grout lines with the grout brush. Pay attention to the area around the toilet base.

10. Final Touches

Wipe down light switches, door handles, and towel bars. Replace clean bath mats and towels. Run the exhaust fan for 20 minutes to dry the bathroom.

Frequently Asked Questions

How long does a bathroom deep clean take?

45–90 minutes for a standard bathroom, depending on the level of buildup. Applying cleaners to multiple surfaces simultaneously (toilet bowl, shower walls, grout) while you work on other areas significantly reduces total time.

How often should I deep clean the bathroom?

Monthly for most households. Weekly cleaning of high-touch surfaces (toilet, sink, mirror) between deep cleans keeps the bathroom hygienic without requiring a full deep clean every week.

What's the most important thing to clean in a deep clean?

The toilet (especially under the rim and the base), the shower grout, and the drain. These areas harbor the most bacteria and mold and are most often missed in regular cleaning.
