Invisia Collection

About Invisia

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.

Why Now

Consider your safety today to stay independent long-term.

Bathrooms are dangerous

Falls can happen to anyone at any life stage—make your home safer for everyone.

No do-overs

Bathroom renovations are costly and disruptive—do this now and you won’t have to renovate again.

Proactive, not reactive

You’ll avoid installing unwanted grab bars in reaction to an injury or fall. 

Peace of mind

You don’t want your loved ones feeling concerned about your safety (or nagging you about it).

Why Invisia

Features & Awards


When you take extra care in your designs, people notice.

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. Sustainable

There 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. Stable

Each 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. Durable

Bamboo 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.

Black by Popular Demand


A timeless finish that stands out and looks beautiful. Design for a darker theme, or add contrast to a lighter theme.

Not Just A Trend.

Trends come and go, but the refined look of Matte Black will add sophistication to your bathroom and continue to impress as it stands the test of time. Whether your style is modern, classic, or industrial, Matte Black is a finish sought out by designers and consumers alike.

Pairs well with your Bathroom.

Matte Black has appeared in projects from top designers and DIYers, as an accent piece or as a theme for the entire bathroom. Whether you’re looking for a matching finish to complete a darker theme, or a darker finish to add contrast to a lighter theme, choose Matte Black from the Invisia Collection.

Beyond Matte Black.

For us, it’s about more than just a finish – It’s about making your bathroom strikingly beautiful while providing support to keep you and your loved ones on their feet.

“Matte Black looks great and enhances the tactile nature of our grab bars.”

– Sunil Achia; Lead Industrial Designer at Invisia™

The award-winning Invisia™ Collection looks great, features a 500 lbs weight capacity, and disguises support in plain sight; safety you’ll notice, but not see.

Serious Space Saver


Save space with a big impact. Optimize space when not in use – no need to lock into place, a machined precision tension hinge prevents the seat from falling down.
