How to unblock a flat shower tray

19 Jul, 2021

Clogs in poorly designed shower trays are very common, due to a number of factors. That’s why it’s so important to have a shower tray that has been designed with geometry that avoids this type of problem.

But what do you do if your shower tray is clogged? In this article, we share how to unblock a flat shower tray in various ways.

It is becoming increasingly common to choose shower trays instead of the typical bathtub. Due to their comfort, aesthetics and space they provide in the bathroom, showers can be a very interesting option.

However, if we don’t choose a shower tray with a good design that has been well manufactured, we can experience inconveniences such as uncomfortable and unpleasant clogging.

It is therefore extremely important to choose shower trays that have been designed with geometry in mind during manufacture and installation. At mcbath, we feature a manufacturing technology that guarantees perfect geometry in our resin shower trays: the mould making technology.

Thanks to this system, our products are much more efficient and have superior technical qualities, avoiding, among other things, the frequent clogging common in other shower trays.

How to unclog a shower tray drain by cleaning the filter inside the wastepipe

The first step to unblock a shower tray drain is to give the inside of the wastepipe a good clean. This is the easiest option, and the first step to unblock your resin shower tray.

To do this, you only have to remove the shower tray grid and take out the filter contained in the wastepipe.

You will see that hair accumulates in this area, which, mixed with soap, tends to form balls of dirt that prevent the water from draining properly.

Then simply put the filter back on the wastepipe, and watch the water flow again!

Unclogging a shower tray by cleaning the inside of the wastepipe with traditional methods

If the first solution fails, it's time to move on to other methods. Let’s take a look at three:

The next step is cleaning the bathroom siphon canister. If the bathroom smells bad, like stagnant water, the problem is most likely in the siphon. With gloves on, take the cover off the siphon canister and remove all the dirt that has accumulated.

Wash with hot water from the shower hose. Take the shower handle and insert the hose into the drain. Turn on the hot water and let it run for a few minutes. With this step, if there’s a dirt plug, it will have to come loose to allow the water to drain properly.

Use a pipe unblocker. If the water still won’t go down, move on to applying an unblocker to the drain. These are usually quite effective at getting rid of dirt, but are not the best option to use as a first choice as excessive use can damage pipes.

Vinegar and baking soda: a natural unblocker. A homemade method for unclogging is to prepare a mixture of vinegar and baking soda, and pour it down the drain. After a few minutes, pour boiling water down the drain to remove the dirt stuck to the pipes.

Unclogging a shower tray pipe using an industrial unblocker

If none of these steps to unclog a flat shower tray have worked for you, it’s time to move on to something more powerful, like an industrial unblocker.

Follow the manufacturer's instructions.

Finally, if none of the options we’ve given you work to unblock the drain in your shower tray, we recommend that you contact a professional plumber.

Remember that the best way to keep your drain functional is cleaning out hair and hygiene products when you're done showering, to prevent them from building up.

And, don’t forget, installing a resin shower tray that has been designed with your geometry in mind is the best guarantee that your shower tray won't clog.
