The Nightmare Of Wet Room Drain Failures

Post by Wet Room Materials

Adding a luxury wet room is a considerable investment. A well-planned design, quality drain and professional installation will ensure a beautiful result that delights your clients. But it’s also important to understand the risks involved with compromising on quality to reduce cost.

When wet rooms go wrong, gaining access to the source of the problem means the tiles and shower area must come up. Fixing the problem is expensive, inconvenient and highly disappointing for your customers. Fortunately, almost all wet room nightmares can be avoided by understanding the causes of common wet room problems.

Wet Room Drainage Problems

The majority of wet room problems arise as a result of ill-considered drainage and poor preparation. Almost all drainage problems lead to leaks – causing damage to decoration, loose tiles, damp problems and unpleasant odours. If undetected, or ignored for long periods, leaks can also cause extensive structural damage.

Inadequate Drainage

Wet room design trends favour the sleek hotel chic look provided by invisible drains. This style relies on sourcing the right type of drain to cope with the volume of water produced. Too low a drainage capacity and the shower area will flood. If water reaches beyond the tanked area the wet room will leak. Always check that the drain can cope with the volume of water produced by the shower head and that it has internal drainage slopes built in to ensure every last drop of water drains away.

Poorly Positioned Drains

Drains positioned below the feet of the user are uncomfortable and impede the flow of water to the drainage channels, causing water to back up. Wall mounted or corner drains remove this problem. A high capacity linear design with smooth edges can be used when the drain can only be positioned in a central location.  It’s imperative to use a drain that strong and that will not buckle under weight.

Miscalculated Floor Depth

Failure to calculate enough floor depth for both the drain and the waste fall drainage pipes can prevent the water from draining effectively. If the waste fall is too shallow, water cannot flow to the soil stack, leading to flooding. Where space is limited, a low-profile drain can be used to provide additional depth.  Wet room Materials have a full range of low profile solutions from only 59mm deep.

Incorrect Floor Slopes

A poorly constructed floor slope can cause water to run in the wrong direction, instead of gently sloping towards the drain. Too great a slope increases the risk of slipping and too low a slope creates insufficient drainage. A wet room that doesn’t drain properly is cold, damp, impractical for use, and frustrating to clean. Floor slopes should contain an even gradient of 1.5% to 2% towards the drain area. This can be achieved through specialist installation using a professional wet room kit.

Low-Quality Drain Design & Manufacture

Choosing a cheap drain system can be a costly mistake. High-quality solutions are manufactured to ensure seals and drainage components meet rigorous standards. A quality drain will be designed with an anti-odour barrier to prevent drain smells rising.  Seek drains that include a removable trap, providing easy access for cleaning and removal of hair blockages. These simple features can make all the difference when keeping your wet room fresh.

Cheaper drain grates may look good initially, but low-quality materials can discolour and deteriorate, spoiling your high-end look. Choose designs with a high spec finish supported by a quality guarantee to avoid disappointment.
