5 Mistakes to Avoid When Creating a Wetroom

A wetroom should be the perfect blend of luxury, practicality, and long-term durability. At Wetroom Innovations, we’ve spent years perfecting products like the Maxxus and Underlay Wetroom Floor Formers and our High Grade Tanking Systems to make sure your wetroom isn’t just stunning on day one, but still flawless years later. Whether you’re a homeowner, installer, or designer, avoiding these five common mistakes will help you get the best results—and protect your investment.

1. Skipping Thorough Waterproofing

Waterproofing is the foundation of any successful wetroom. Neglecting it can cause leaks, structural damage, and persistent damp. With Wetroom Innovations’ Tanking Systems, you can create a fully watertight barrier on floors and walls quickly and easily. Our systems bond directly to most surfaces, ensuring complete protection and peace of mind from day one.

2. Improper Drainage Design & Floor Gradients

Without the right floor slope and drainage, water will pool rather than flow away. Our Wetroom Floor Formers are pre-sloped for perfect drainage and are strong enough to take heavy loads without flexing—eliminating the risk of cracked grout or leaks.

Our drains don’t just look good—they offer exceptionally high flow rates, ensuring water is whisked away quickly, even during powerful showers or in family bathrooms with frequent use.

3. Using Inadequate or Poor-Quality Materials

Choosing weak or unsuitable components—such as flimsy floor formers or untested waterproofing membranes—can quickly compromise your wetroom. The Maxxus isn’t just strong; it’s one of the strongest wetroom trays on the market, and it’s compatible with underfloor heating. Combined with our Paint-On Tanking, you get a professional-grade waterproofing and flooring solution designed to last for decades.

4. Underestimating the Importance of Ventilation

Even the best waterproofing can’t fight constant condensation without good airflow. Poor ventilation invites mould, mildew, and odours. A high-quality extractor fan, used alongside our waterproofing systems, ensures your wetroom stays fresh, hygienic, and healthy.

5. Hiring an Inexperienced Installer

Wetrooms require precision installation, and not every tradesperson has the necessary expertise. Our team offers expert advice, installation guides, and aftercare support—so your chosen installer can work confidently with our products.

Final Word

When it comes to wetrooms, cutting corners is costly. By choosing Wetroom Innovations’ Floor Formers, Tanking Systems, and professional drainage solutions, you’re investing in a wetroom that looks beautiful, performs flawlessly, and stands the test of time.
