Common Causes of Shower Drain Blockages

1. Hair Buildup

Hair is the most common cause of shower drain blockages. When mixed with soap residue and body oils, it creates a buildup that can block the drain opening.Every few weeks—or more often if you have long hair in your family—you should remove the drain cover and have a quick look around.Most shower grates can be removed with a flathead screwdriver or simply lift out. You'll typically find an accumulation of hair around the trap opening. Wear rubber gloves and remove the hair buildup by hand or with a drain cleaning tool.Hair catchers are available from Bunnings, Reece Plumbing or your local hardware store for around $5-$15. They can be found in various styles to suit your bathroom. While you're shopping for drain solutions, you might also want to browse other essential bathroom accessories that can help keep your bathroom clean and functional. You will need to clean hair off it frequently but it should stop most of your problems before they start.For minor soap buildup, you can try the bicarb and vinegar method. Pour boiling water down the drain first to help dissolve any soap residue which may be sticking on pipe walls. Follow that with 1/3 cup of bicarb soda, then pour 1/2 cup of white vinegar over it. After about 15 minutes let it fizz for a bit; then rinse thoroughly with hot water again. This works for light blockages, but won't clear hair accumulation or major obstructions.

2. Soap Scum Accumulation

Soaps made from fats can create a sludge at the bottom of the drain. When they mix with hair and other debris, they can cause a blockage to the fixture.Bicarb soda and vinegar is a natural way to clear this type of blockage. Use 1/3 cup of bicarb soda and pour 1/2 cup of vinegar. Allow to fizz for 15 minutes, then flush with hot water. A plumber can use a jet rodding machine to give the drains a thorough clean. This is the most effective way to prevent buildup and future blockages.

When the Blockage is Further Down the Drain

If the problem's not right at the grate, sometimes it may be further down in the pipe and tougher to deal with. When even after clearing away what you can see your water still isn't draining quickly, you may have to use a plunger made just for drains (not the toilet one-please). Seal off the drain opening with the plunger and give it a few good pumps.Avoid chemical drain cleaners where possible as they can damage older pipes and are harmful to the environment. If you must use them, follow the instructions exactly and never mix different products as the chemical reaction can be dangerous.If you shave in the shower, avoid rinsing hair directly down the drain. Shaving cream mixed with hair can create stubborn blockages that are difficult to clear.

Preventing Shower Drain Blockage

Prevention of the blockage is way more preferable than having to deal with it. Do yourself a favour and slip a hair catcher over the top of your shower drain.Regular maintenance is simple. Every few weeks, remove the drain cover and clear away any hair buildup. A quarterly clean with boiling water and bicarb soda and vinegar can help prevent soap scum accumulation. Just as you regularly maintain your shower drain, items like toilet brushes holders should also be cleaned and replaced periodically to maintain overall bathroom hygiene. Check the drain grate is secure and in good condition every six months or so.

When to Call a Licensed Plumber

Regular drain cleaning is something you can do yourself, but major blockages will require a licensed plumber.

Call a plumber if:

Water backs up into other fixtures
You notice water coming from wall cavities
Bad smells persist after cleaning
Nothing you've tried has worked
Water is coming up the drain when other fixtures are used

A plumber's call-out to clear a blocked shower drain typically costs $150-$300 depending on the severity and location of the blockage. This is why regular maintenance is worth doing yourself.Persistent odours after cleaning can indicate problems with the waste trap or drain ventilation. This will need a plumber to investigate and fix.Regular cleaning of your shower drain takes just a few minutes but can prevent major blockages and costly plumbing call-outs.

FAQs

How often should you clean a shower drain to prevent blockages?

A quick check every few weeks is usually enough to keep things under control. Remove the drain cover, clear away any visible hair buildup, and make sure the grate is sitting properly. Every few months, flushing the drain with boiling water followed by bicarb soda and vinegar can help break down soap residue before it forms a sludge.

Does the bicarb soda and vinegar method actually clear a blocked shower drain?

Bicarb soda and vinegar can help with light soap scum buildup or minor residue inside the pipes. It’s a simple maintenance method rather than a solution for serious blockages. If hair or debris has formed a solid obstruction, you’ll usually need to remove it manually or use a drain cleaning tool.

When should you call a plumber for a blocked shower drain?

If the water still drains slowly after you’ve cleared the grate and tried basic cleaning methods, the blockage may be further down the pipe. Persistent bad smells, water backing up into other fixtures, or water rising in the shower when other taps are used are also signs of a deeper plumbing issue that should be checked by a licensed plumber.
