Mould-Proof Shower – Create Your Own

Mouldy Shower

Mould Proof Shower StallAre you tired of seeing thatOkay – we know that it’s almost never that bad. That doesn’t change the fact that everyone reading these words right now has seen bathroom mould, and what you see is nothing compared to what you don’t.

Bathroom mould is generally viewed as an inevitable homeowner hardship, and not without reason. Kitchens and bathrooms are obviously high-moisture areas.

But what about a mould-proof shower?

Imagine if mould and mildew never plagued the surfaces of your shower stall at all. Imagine if the unseen interior of the stall stayed dry, no matter how much use it saw. You may say I’m a dreamer, but I’m not the only one.

We found that Brad Elkins – a homeowner, not a handyman – may have fulfilled this dream in 2012. He used new materials and with a new approach, and we’d like to summarize his findings for you.

Brad Elkins - Kerdi Board TilesIn creating his mould-proof shower, Elkins did not opt to use water-resistant drywall.

He used Kerdi-Board, a product manufactured by Schluter that serves as “a multifunctional tile substrate and building panel.” 

The company states that the product can be used to create “bonded waterproofing assemblies with tile coverings” and, as you can see, this is precisely what Elkins did.

After stripping the walls, Elkins began by covering the studs with 3/4” Kerdi-Board. This protected the wall, but not the corners, seams and on top of the washers and screws.

He troweled some thinset mortar on these areas in order to secure a sheet of Kerdi – widely available and powerful waterproofing membrane – in and around these gaps in his mould-proof shower’s defenses. 

Waterproof Floor Uncoupling MembraneThe walls, corners and even the seams were covered by a powerful membrane, but Elkins needed to protect the floor as well.

Many people make the mistake of believing that the tiling itself will protect the flooring – it doesn’t.

Instead, Elkins used an uncoupling membrane – another widely-available product from Schluter, made from heavy plastics – to cover his floor before installing the tiles themselves.

This left the floor’s corners and seams as the only remaining areas around his shower that were unprotected. And considering he still had an abundance of Kerdi left, this wasn’t a problem.

According to a 2009 study, Canadians use an “alarming” amount of water. A mould-proof shower is, in other words, precisely what this country needs.

Winter Condensation Problems: Best Solutions

Solving Your Winter Condensation Problems

winter condensation problems

You’ve almost certainly seen this before. Perhaps not to this degree, but we’ve all woken up after a brutal winter night to a very wet window sill.

Canadians have become all-too-familiar with the winter condensation problems that surface in any region where the temperatures are cold enough.

Your windows ‘sweat’ the same way that the cool surfaces in your basement do. When the humid air inside your artificially-heated home meets the freezing temperatures on the other side of the window, condensation will begin to appear on the glass.

Condensation MouldThe effects of winter condensation problems are absolutely detrimental to your home.

The finish of the window frame itself will be damaged, and the moisture will create an ideal breeding ground for mould. Dry the sill with a towel whenever necessary.

If you find yourself needing to wipe it down periodically throughout the day, then this is an indication that your home has ventilation issues and it’s then that the ramifications of winter condensation problems become much more serious.

In a home with such poor indoor air flow, condensation will start occurring inside  the walls and attics. This will lead to the unnoticed growth of mould, mildew and other such fungi – well, unnoticed until it ‘blossoms’ into a situation like the one above and to the left.

What’s causing  the winter condensation problems? We are. Everyday parts of the human routine such as cooking, drying clothes, taking a shower and even breathing all create moisture, as does the heating system you use to warm your home on cold nights.

Exhaust Fan in KitchenHow then do we solve the problem?  Identify all of the high-moisture areas in your home – think kitchens and bathrooms – and install an exhaust fan in every single one. Every time someone takes a bath or a shower, the exhaust fan should run for the next 15-20 minutes. 

The one downside to this solution is that the exhaust fans will draw warm air out of your home, and in this weather that’s something no one wants.

After all, that’s why we close all our windows this time of year. The upside is that it’s an affordable and efficient means of ventilating your home.

There is a wonderful alternative and it would remove the issue of heat loss – however, it will set you back more than $2,000.

The heat recovery ventilator – also referred to as an “air exchanger” – extracts around 80% of the heat from your indoor air before sending it outdoors. Simultaneously, it draws the fresh air outside into your home and releases it – nicely pre-heated – into your home. Pretty cool, huh?

Stay Warm!

Every problem has a solution, and winter condensation problems are no exception. Older, drafty homes never faced condensation because the holes around doors and windows formed a natural ‘ventilation system.’ With the technology available to us today, we no longer need to choose between cold and mould.
