The Soaked Saga of an Old Shower Leak


Ah, the beloved shower – the daily rendezvous with your inner diva or rockstar (depending on your playlist). But did you know that behind those lovely tiles and steamy sessions lies a wet secret? Yes, the lurking menace of leaks and water damage! In this informative yet humorous journey, we'll uncover the wet and wild world of showers, discuss the outdated mortar beds and vinyl liners (and why they leak), and introduce you to the glorious Schluter shower base. Buckle up; it's going to be a splash!


The Leaky Legacy of Mortar Beds and Vinyl Liners

Picture this: You're enjoying a steamy hot shower when suddenly, you feel a cold droplet on your head. No, it's not a supernatural visitation; it's a leak! Traditional showers used to be built with mortar beds and vinyl liners. They may have seemed solid, but they were about as waterproof as a sieve. Over time, the mortar would crack, and the vinyl liner would degrade, turning your bathroom (or your neighbor's bathroom) into a DIY waterpark.


Why Mortar Beds and Vinyl Liners Are No Longer The Norm

A Troubled History With Health and Safety

While these systems are still in use in much of the US, especially in the south, they require an enormous amount of expertise to install properly. In New York City, they are installed with a hand-formed lead pan underneath, In the south, they are installed with a "hot mop" system. "Hot mop" is when the shower base is coated with hot liquid tar prior to installing the mortar bed and vinyl liner. When they are installed using these systems, they can indeed be very durable. Because this system has fallen out of favour in Montreal (and Canada in general), there is little expertise in this domain.


A few issues are common to older methods of shower waterproofing. One is the use of hazardous products. Both lead and bitumen or tar contain known carcinogens which are hazardous to the installers. They also have the potential to leach into the water systems and leave trace level contaminants.


Another issue is the amount of mortar required to create the slope. Not only does this leave room for error which can cause pooling in low areas, but it also leads to a perpetually humid shower base assembly. Because tiles are not waterproof, but only water-shedding (more on that here), the entire base assembly soaks up water and stays damp which can lead to a moldy or mildew odor and eventually propagate mold spores in the worst of installs.

Now, let's introduce the star of our show – the Schluter shower base! It's like the superhero of bathroom renovations. With its foolproof design and waterproofing prowess, Schluter is here to save your day. The installation process is as smooth as a shower gel commercial, and the results? A leak-free, beautiful shower that can withstand the waterworks of a rock concert.


The beauty of the Schluter waterproofing membrane is that it is directly beneath the tiles, whereas the old vinyl liners were under the thick mortar bed. This prevents waterlogging and directs water directly to the drain which is bonded to the membrane. This minimizes the risk of leaks and mitigates the issues related to mold and moisture retention.
