The shower fills to your ankles by the end and drains for a while after you get out. There are three things people reach for — a hair clog remover, a drain snake, or a bottle of something caustic — and they are not interchangeable. They address different blockages, and picking wrong is how a ten-minute job becomes a plumber.
First, work out what is actually in there
Bathroom drains and kitchen drains clog differently, and that single distinction decides your tool. A bathroom clog is nearly always hair, bound together with soap scum into a dense mat sitting just below the strainer or in the trap. A kitchen clog is grease, which coats the pipe wall and narrows it gradually rather than plugging it.
If the water drains but slowly, and the sink is a bathroom sink or a shower, assume hair until proven otherwise. If it is a kitchen sink and the slowdown came on over months, assume grease.
The hair clog remover: a barbed strip, and the right first move
A hair clog remover is a long flexible strip or rod with backward-facing barbs or bristles down its length. You feed it past the strainer, twist, and pull. The barbs catch the mat and bring the whole thing out in one piece.
It is unglamorous and it is usually the correct answer, for a reason worth stating plainly: it removes the clog from the house. A chemical dissolves part of the mat and leaves the rest in the pipe to re-form. A snake often pushes a hair mat further along rather than gripping it. The barbed strip is the only one of the three that reliably brings the problem out where you can see it and bin it.
- Feed it in slowly. Forcing it past the trap bend is how the strip snaps and leaves a piece behind.
- Twist as you withdraw, not as you push.
- Expect it to take two or three passes. The first pull gets the bulk, the second gets what the first loosened.
- Do it over a bin bag. What comes out is genuinely unpleasant and you will not want to carry it far.
The drain snake: for clogs past the trap
A snake — an auger — is a long coiled cable with a cutting or corkscrew head, cranked into the pipe to break up or hook a blockage further down the line. It reaches where a hand tool cannot, and it is the right escalation when the barbed strip comes back clean but the drain is still slow: that tells you the blockage is beyond the trap.
It is more tool than most bathroom clogs need, and on a hair mat specifically it is often worse than the cheap option, because a smooth head can compact a mat rather than catch it.
Chemicals: last, and not on a dense mat
Chemical cleaners work by heat and caustic reaction, using sulfuric acid or sodium hydroxide to break organic matter down. They are genuinely effective on soft, loose material spread through a trap, and on grease. They routinely stall on a dense hair wad that has been compacting for months, because the reaction only touches the surface of the mass.
The cost is the pipe. Repeated use degrades pipework, and the risk is highest in older homes with metal waste pipes. There is also a practical trap: if the chemical does not clear the clog, you now have a blocked drain full of caustic liquid, and the mechanical tools you should have used first have become a much less pleasant job.
When the clog comes straight back
If you clear a drain and it slows again within a week or two, the mat you pulled was the visible end of something larger sitting further down, and the tool is not the problem.
The next step is the trap itself — the U-bend under a sink comes apart by hand or with a basin wrench, and clearing it directly is a twenty-minute job that removes everything the strip could not reach. Put a bucket underneath first; it is full of water and you will not enjoy discovering that empirically.
A shower is harder because the trap is usually inaccessible, which is the case for a snake rather than a strip. If a snake also comes back clean and the drain is still slow, the blockage is beyond the fixtures and into the branch pipe, and that is the point at which a plumber is cheaper than continuing to guess.
A drain that has never run properly since you moved in is a different diagnosis again — that is often a fall or venting problem in the pipework rather than anything you can pull out.

Frequently asked questions
Which should I try first?
The barbed strip, almost always, if the drain is a bathroom one. It is the cheapest, it does no harm if it turns out to be the wrong tool, and it removes rather than relocates the blockage. Escalate to a snake if it comes back empty.
How often should I do it?
For a household with long hair, roughly every couple of months as maintenance rather than as a rescue. A mat pulled at two months takes thirty seconds; the same mat at a year is a fight.
Do drain covers make this unnecessary?
They reduce it substantially, which is a better outcome than any of the three tools. A cover that catches hair at the surface means you are cleaning a strainer rather than a trap. It does not eliminate the job — enough gets past — but it changes the frequency.
