Key facts: Shower and Bathtub Drain Cleaning
- Henderson's water comes entirely from the Colorado River via Lake Mead and carries calcium and magnesium that make it hard [1].
- Water above 180 mg/L as calcium carbonate counts as very hard, and Henderson's supply sits well above that line [2][1].
- Hard water reacts with soap to form scum and leaves mineral scale, more of it where water is heated [3].
- Shower and tub drains use a trap whose water seal keeps sewer gas out of the bathroom [4].
Is it clogging?
Signs your shower or tub drain is losing the battle
Water around your feet
A shower that used to drain as fast as it ran now leaves a puddle that takes minutes to go down.
Ring of gray film
A dirty line around the tub or shower pan shows where water sat while waiting to drain.
Stopper that will not open fully
A tub stopper stuck partway down, or one that barely lifts, often has hair and scale built up around its mechanism.
Musty or sewer smell
Hair and soap trapped below the drain start to rot in a warm bathroom, and the smell drifts up through the grate.
Gurgling when the toilet flushes
If the tub burbles or water rises in it when someone flushes, the clog is probably further down in a shared line.
Slow drain in only one fixture
Usually a good sign. The clog is likely within the first foot or two and easy to reach.
How it forms
The Henderson shower clog: hair plus scum plus scale
Hair alone mostly slides through. What makes it stick is what else is in the water. Henderson's supply is very hard, at some 16 grains per gallon [1]. [2] Calcium and magnesium in that water react with bar soap to form a sticky curd, the scum you see on glass doors [3].
That scum coats hair strands and binds them into a mat. Meanwhile, warm shower water drops a thin layer of mineral scale on the drain body and crossbar every day [3]. The scale is rough, so the mat hooks on. Within a few months the opening under the grate can shrink to a fraction of its size.
- Hair provides the structure
- Soap scum glues it together
- Mineral scale gives it something to cling to
- Warm water speeds up scale on the drain parts

Know your drain
Common shower and tub stoppers and how they clog
The type of stopper changes how easy it is to clean. Most Henderson bathrooms have one of these.
| Drain type | How you recognize it | Where hair collects |
|---|---|---|
| Toe-touch stopper | Push with your foot to open or close | On the threaded post under the cap |
| Lift-and-turn stopper | Small knob you lift and twist | Around the post and the crossbar below |
| Pop-up with trip lever | Lever on the overflow plate | On the rocker arm inside the drain and overflow tube |
| Plunger-style trip lever | Lever, but no visible stopper | On the hidden plunger inside the overflow tube |
| Shower grate | Screwed or snap-in flat grate | Directly under the grate and in the trap |
| Linear drain | Long narrow channel in tiled showers | Along the channel and at its outlet |
Tub overflow plates usually come off with two screws, which also gives access for a small auger.
DIY
What you can safely do yourself
Most shower and tub clogs are within reach. Work through these in order and stop if anything feels stuck or forced.
- Remove the stopper or grateUnscrew or pull out the stopper, or lift off the shower grate. Pull the visible hair out with gloved fingers or pliers.
- Use a barbed plastic stripFeed it down beside the crossbar, twist and pull. It grabs the mat that sits just below what you can see.
- Pull the trip lever assemblyOn tubs with a lever on the overflow plate, remove the two screws and lift out the linkage. Hair often wraps the bottom of it.
- Plunge with the overflow sealedCover the tub overflow with a wet rag, add a couple of inches of water, then plunge. The seal makes the pressure go where it is needed.
- Soak scale-crusted parts in vinegarRemovable stoppers and grates can soak in white vinegar to loosen scale. Rinse well before you put them back.
The visit
How the contractor clears a stubborn shower or tub drain
- 1
Test the surrounding fixtures
Running the tub, sink and toilet in the same bathroom shows whether the clog is local or further down.
- 2
Remove stopper and overflow parts
The stopper, trip lever linkage and any grate are removed and cleaned or replaced if badly scaled.
- 3
Snake through the overflow or drain
A small drum auger is fed through the overflow opening, which lines up better with the trap than the drain itself. The cable cuts through and pulls back the hair mat [6].
- 4
Work the line toward the main
If the clog is past the trap, the cable is run further into the branch line, which on most Henderson homes lies under the slab [7].
- 5
Consider jetting or a camera
For drains that clog over and over, hydro jetting can scour scale from the line, and a camera inspection can show whether something structural is to blame.
- 6
Reassemble and run a full test
Parts go back with fresh gaskets where needed. The tub is filled and drained, and the shower is run for several minutes to confirm it keeps up.
Local factors
Why do Henderson showers and tubs need extra care?
Every city sees hair clogs. Henderson's very hard water just makes them form faster and hold tighter. The city's water report notes the calcium and magnesium are not a health concern [1], but anyone who has scrubbed a shower door here knows how quickly they show up. What you see on the glass is also forming inside the drain.
Slab construction adds another wrinkle. Homes here rarely have basements, so a tub or shower drain drops straight into the concrete and runs under the floor to the main [7]. When a clog sits beyond the trap, it cannot be reached from below and has to be cleared from the fixture or a cleanout. Our slab drain line clogs guide explains what that means for a repair.
Then there are guest bathrooms. Henderson's hot, dry summers, with typical July highs near 101°F [8], can evaporate the water out of a tub or shower trap that nobody uses for a while [4]. That lets sewer odor into the room. It is easy to mistake for a clog, and easy to prevent by running the shower for a minute every couple of weeks.
If your main shower is simply slow rather than stopped, the slow-draining shower guide walks through more troubleshooting.
If the tub is only one of several slow drains, start with clogged drain repair instead.

Shower or tub?
Why does a shower clog differently from a tub?
A walk-in shower has no stopper, just a grate over an open drain. Hair falls straight through and collects in the trap a few inches down, so shower clogs tend to build lower and are reached with a hand auger once the grate is off.
A tub has a stopper and an overflow, which means more moving parts in the water path. Hair tends to catch higher up, on the stopper post or the trip lever linkage, and many tub clogs clear completely once those parts are pulled and cleaned. Combination tub-showers get both kinds of trouble, because they see the daily volume of a shower and have the hardware of a tub.
Newer homes, such as those in Inspirada, where building began in 2007 [9], may have walk-in showers with tiled pans or linear drains. Those look sleek but have more surface for scum to grip, so they reward regular wiping. Older homes more often have a standard tub with a trip lever, and that hidden linkage is usually where the contractor finds the worst buildup.
Either way, tell the contractor which kind of drain you have when you call. It helps them bring the right size auger.
Prevention
Habits that keep showers draining
Add a strainer that catches hair
A simple mesh or silicone catcher over the drain stops most hair. Empty it after every few showers.
Brush before you bathe
Brushing long hair before showering means less of it ends up in the drain.
Switch to liquid soap
Bar soap reacts with hard water to form more scum [3]. Liquid body wash leaves less residue in the trap.
Rinse hot after each shower
A short blast of hot water at the end helps move loose soap film along before it sets.
Clean the stopper monthly
Pulling and wiping the stopper once a month stops hair from building into a mat.
Consider softening
A water softener reduces new scale and scum. It will not remove buildup already in the pipes.
Urgent cases
When a tub or shower clog becomes an emergency
A slow shower is a nuisance. Dark or smelly water rising in the tub when you flush a toilet, run the washer or use the kitchen sink is something else. That points to a blockage in the main line, and the tub, sitting low, is simply where it shows first.
If that happens, stop using water anywhere in the house, keep children and pets out of the bathroom, and go to emergency bathroom drain cleaning. Call to check emergency availability. The guide to main sewer backup signs will help you judge how serious it is.
FAQ
Shower and bathtub drain questions Henderson homeowners ask
Spoken questions about shower and bathtub drain cleaning, answered briefly. Other topics: [questions hub](/faq/). Back to [the services overview](/services/).
Why does my shower drain clog every few months?
A shower drain that clogs every few months usually collects hair bound with soap scum, which builds faster in hard water. Henderson's water carries calcium and magnesium that react with soap [1][3]. A hair catcher and occasional cleaning help, but a drain that clogs this often may need a deeper clearing.
Why does the contractor snake a bathtub through the overflow opening?
A bathtub is often snaked through the overflow opening because it gives a straighter path into the drain line than the tub's own drain and stopper. Removing the overflow plate lets the cable bypass the stopper mechanism. The contractor you're connected with chooses whichever route clears the line with less risk to the finish.
Why does my bathtub fill up when I flush the toilet?
A bathtub that fills up when you flush the toilet usually points to a main sewer line blockage, because the tub is often the lowest drain sharing that line. Water backs up at the lowest point first. Stop using water and call to have the main line checked rather than treating the tub alone.
Is it safe to use a wire coat hanger to clear a shower drain?
A wire coat hanger can pull hair from just below a shower drain, but it can scratch finishes and push clogs deeper. A plastic hair-removal tool is usually gentler. If the clog is beyond reach, a small hand auger is a common next step that reaches further without harming the finish [6].
Do linear shower drains clog differently from round ones?
Linear shower drains often clog differently because hair and soap collect along the long channel rather than in one small grate. The channel can be lifted out for cleaning. Linear drains still use a trap with a water seal [4], so the clog may also sit further down.
Why does my bathtub drain smell even when it drains fine?
A bathtub drain that smells while draining fine usually has soap and hair buildup in the trap or stopper, or a dried-out seal in a tub that is rarely used. The trap water blocks sewer gas [4]. Running water and cleaning the stopper usually solves it; persistent odors may need a check.
Can chemical cleaners damage my shower or bathtub drain?
Chemical drain cleaners can damage some shower and bathtub finishes, older pipes and seals, and mixing products can cause dangerous reactions [5]. A plunger, hair-removal tool or hand auger is usually safer. If you have used a chemical cleaner, tell the contractor before they open the drain.
How do I unclog a shower or bathtub drain that keeps clogging?
A shower or bathtub drain that keeps clogging usually needs the hair-and-soap plug removed at the grate or stopper, not just pushed further down. Lift the grate or stopper, pull out what you can with a plastic barbed strip, then plunge with the overflow covered. If it slows again within weeks, scale or buildup deeper in the line is likely, and the contractor can clear and check that section.
