Bathroom Drain Cleaning Cost

Slow shower, gurgling sink, toilet that needs two flushes — bathroom drains clog more often than any others in the house, and the culprit is almost always hair plus soap scum. The bathroom drain cleaning cost in 2026 runs $100-$225 per drain for professional service (about $150 average), with most bathroom clogs sitting close to the drain opening and clearing in under 30 minutes. That makes bathroom drains the cheapest and quickest fixture work a plumber does. This guide breaks down pricing by fixture, what actually works for DIY, and the $5 fixes that stop clogs from forming in the first place.

Average Bathroom Drain Cleaning Cost

Pro tip: if two or three bathroom drains are slow, have them all serviced in one visit. The first drain carries the service-call cost; each additional drain is only $40-$75. A whole-bathroom refresh (sink + tub + toilet check) typically lands around $225-$300 total.

Cost by Fixture: Sink, Tub, Shower, Toilet

• Bathroom sink ($100-$200): Hair and toothpaste/soap residue wrap around the pop-up stopper assembly, usually within 12 inches of the drain. Many plumbers clear these by simply removing and cleaning the stopper — a 10-minute job at the low end of the range.
• Tub and shower ($100-$225): The classic hairball clog, typically 1-3 feet down. A hand auger or plastic hair snake ($5) reaches most of them. Crossbar strainers in older tubs can complicate DIY removal — a pro handles them in minutes.
• Toilet ($125-$250): Toilets need a closet auger with a protective sleeve, not a standard snake. If the blockage is past the trap and the toilet must be pulled, add $100-$150 for the pull and reset with a new wax ring.
• Bidet or specialty fixtures ($125-$225): Priced like a sink drain; the main variable is access to the trap.

Bathroom clogs rarely require hydro jetting — the blockage is soft organic matter near the opening, exactly what augers handle best. If a plumber quotes jetting for a simple bathroom sink clog, that is a red flag; see our hydro jetting vs snaking guide to know when each is appropriate.

What Causes Bathroom Clogs

• Hair (the #1 cause): Sheds daily, wraps around stoppers and strainers, and combines with soap into dense mats. Long hair and pet hair are the worst offenders.
• Soap scum: Bar soap and some body washes leave a waxy residue that binds hair into solid masses. Liquid body wash produces less scum than bar soap.
• Toothpaste and shaving cream: Harden in the trap and narrow the passage over time.
• "Flushable" wipes and hygiene products: Do not break down like toilet paper. They cause the most expensive toilet clogs — the ones requiring a toilet pull.
• Mineral scale: In hard-water areas, calcium deposits narrow older pipes and give debris something to snag on.
• Kids' toys and objects: A surprisingly common toilet-clog cause. If the toilet clogs right after a toddler's bathroom trip, suspect a toy before anything else.

Older plumbing makes everything worse. Homes built before the 1970s often have galvanized steel drain lines that corrode from the inside, shrinking the pipe diameter year by year until even normal hair and soap can't pass. If your older home's bathroom drains clog every few months despite screens and good habits, the pipe itself may be the problem — not what goes down it. A camera inspection reveals interior corrosion clearly, and at that point the conversation shifts from $150 cleanings to pipe replacement or relining. Similarly, drum traps (common in pre-1960s tubs) clog far more easily than modern P-traps and can't be snaked effectively without special techniques — if your vintage tub has chronic issues, ask the plumber whether a drum-trap-to-P-trap conversion ($300-$600) makes sense during a remodel.

DIY vs Professional Cleaning

Bathroom drains are the most DIY-friendly clogs in the house. Try these in order:

• Remove and clean the stopper/strainer ($0): Pop-up stoppers unscrew or lift out; most of the clog comes out with them. This alone fixes a huge percentage of slow bathroom sinks.
• Plastic hair snake ($5): A barbed plastic strip that pulls hair out of tub and shower drains in seconds. Keep one under every bathroom sink.
• Flat-bottom plunger ($10): Effective on soft clogs near the drain. Seal the overflow drain with a wet rag first for full pressure.
• Hand auger ($15-$50): A 25-foot hand-crank auger reaches clogs 2-5 feet down — the full range of most bathroom blockages. Our how to snake a drain guide covers the technique.
• Baking soda + vinegar + hot water ($2): Helps dissolve soap scum after the hair is mechanically removed. It will not dissolve a hairball on its own.

Call a pro when: the auger hits something solid it can't pass, multiple bathroom fixtures clog simultaneously (possible branch-line or main-line issue), sewage odors accompany the clog, or the same drain reclogs within weeks. Also call if you've used chemical drain cleaner — tell the plumber first, for their safety.

Keeping Bathroom Drains Clear

• Drain screens ($5-$10): The single best investment. A stainless mesh screen over every tub, shower, and sink drain catches hair before it enters the pipe. Empty it weekly.
• Brush hair before showering to reduce what goes down the drain.
• Switch from bar soap to liquid body wash to cut soap-scum formation.
• Monthly hot-water flush: Fill the tub or sink with hot water and release it all at once — the volume and heat melt soap residue.
• Never flush wipes, cotton balls, or dental floss. Floss in particular wraps around everything in the line and acts like a net for other debris.
• Clean pop-up stoppers quarterly — a 2-minute job that prevents most sink clogs.

A note on hard water: if you live in a hard-water region (much of the Midwest, Southwest, and Florida), mineral scale narrows your pipes from the inside and gives hair and soap something to grip. You may notice white crust on faucets and showerheads — that's the same deposit forming inside your drain lines. A water softener ($800-$2,000 installed) is a bigger investment, but households with softeners report dramatically fewer drain calls because debris slides through smooth, scale-free pipe. At minimum, a $30 showerhead filter reduces scale in the fixture where clogs start.

Toilets deserve special mention because they're the most expensive bathroom fixture to service. The vast majority of toilet clogs are caused by too much paper, "flushable" wipes, or foreign objects — not by anything wrong with the plumbing. Teach the household the "courtesy flush" for heavy paper use, keep a plunger (flange-style, not flat) next to every toilet, and treat wipes like the pipe-killers they are. A $175 toilet augering avoided twice a year is $350 back in your pocket.

Households that use drain screens consistently report going years between professional bathroom drain services. The screens pay for themselves the first time you don't need a $150 service call.

One last habit that costs nothing: run the hot tap for 30 seconds after every shower. That sustained flow of hot water melts fresh soap residue before it hardens onto the pipe walls, and it takes zero effort — just don't turn the tap off the moment you step out. Combined with a drain screen, this single habit eliminates the majority of repeat tub and shower clogs.

When the Problem Is Bigger Than One Drain

One slow drain is a fixture problem. Several slow drains — especially across different bathrooms — is a system problem:

• Branch line clog: The horizontal pipe serving one bathroom. Costs $150-$300 to clear.
• Main line clog: Every drain in the house affected, toilets gurgling, lowest fixtures backing up. See main line cleanout cost ($200-$600 to clear).
• Vent blockage: Slow drains plus gurgling with no actual clog — a blocked roof vent prevents proper drainage. Usually $100-$200 to clear.
• Sewer camera diagnosis: When the pattern doesn't make sense, a drain camera inspection ($200-$300) shows exactly what's happening inside the pipe.
