Leaking showers are a common problem in Australia. What’s worse is the damage it can cause can be quite extensive, and repairs can be very costly. If you find unsightly stains on the walls, rotten plasterboard and timber, there is a good chance you have a leaky shower.

Here are some of the main causes of a leaky shower:

• A faulty or missing tray at the base of the shower
• Cracked wall sheeting in the shower recess
• A leak in the connection between the shower outlet and the drain pipe
• Broken or missing grouting
• Wall lining not sealed
• Leaking tap fitting (behind lining)
• Leaking water pipe or joint

How to fix it:

The most likely cause of leaky shower recess is a faulty or missing shower tray. You can install new copper, stainless steel, PVC, or applied polymer material trays. This requires extensive and expensive removal of the floor and wall tiles and after installing the new tray, you will need to re-tile the base and the walls.

Such work should only be carried out by a licensed tradesperson. Using silicone mastic to prevent leaky showers in unlikely to work if the cause is other than faulty or missing grouting around the shower base. Sometimes, it is possible to replace the whole shower with a prefabricated fibreglass unit that fits inside the space of the shower. This should be attempted by a professional plumber.

On one hand, leaky baths are usually caused by a faulty connection at the bath outlet. To fix such problem will require the removal of the hob wall alongside the bath.

When renewing a shower recess to fix a leak, check if the taps are not properly installed. You need to be in the shower to adjust the water temperature. A well thought out shower will have the taps located in a position where adjustments can be made before entering the shower area. You may also consider installing a ‘telephone’ type shower head on a flexible hose with a grab handle in the shower.
