In major industries, safety has become standard because products have been designed with the user in mind. Similar to major paradigm shifts in those industries, change is required for bath safety to advance. Nobody wants their bathroom to look like a hospital.
Invisia™ was designed to address the stigma associated with the “look” of traditional bath safety products.
We strive to normalize safety, especially for those who are making efforts to age in place. We are inspired by potential, both our own and that of our customers. We are transforming the experience of grab bars and bathroom seating to create beautiful bathroom accessories that elevate a space while simultaneously creating a safer environment.
Consider your safety today to stay independent long-term.

Stable & Sustainable
Design you can feel good about – bamboo is the only material that checks off style, quality, strength, and feel while being environmentally conscious. There are many different kinds of bath seats on the market today – teak and phenolic are two popular ones for example. In fact, back in 2015 Invisia™ made the change from Brazilian Walnut seats to Bamboo. So why did we make the change? There are 3 main reasons: 1. SustainableThere are over 2000 different types of bamboo, and most typically grow 3-5 feet a year. Some varieties can grow up to 12″/30cm in one day! Teak takes up to 25 years to grow into ONE mature tree, and some varieties take 80-120 years to mature. 2. StableEach seat panel we use is made from bamboo strands glued together to make a solid, engineered material that does not warp or twist. Many building material tests show that bamboo under tension is comparable to steel. As a result, Invisia™ seats have a weight capacity of 500lbs/227 kgs (which supports 20-40% more weight than most teak seats on the market). 3. DurableBamboo is grown in hot, humid, and wet climates – similar to a shower environment. Invisia™ uses 1″/2.54cm bamboo panels so they won’t crack, warp or leach. Bamboo is naturally stain-resistant, we apply a rubio monocoat oil to protect the bamboo’s colour and grain to enhance its natural look and feel. While other materials we’ve tested can make an adequate seat, bamboo is the only material that checks off style, quality, strength, and feel while being environmentally conscious. |
