Frequently Asked Questions

How does the tool-free knock-down assembly work?
The RB670 uses a snap-together or push-button assembly system that allows the bench to be assembled and disassembled without any tools. The legs and seat components connect and lock into place by hand, and can be released and folded flat for storage or transport in the same way. This makes the bench practical for travel, for facilities that need to store benches between uses, and for caregivers who set up and take down equipment frequently. Always confirm all connections are fully locked before the user sits on the bench.

Why is composite construction better than metal for a bath bench?
Metal bath benches — typically aluminum — can develop surface corrosion and rust at joints, welds, and adjustment points over time when exposed to the constant moisture and cleaning chemicals of a bathroom environment. Composite (plastic) construction is inherently rust-proof and corrosion-resistant, requiring no special maintenance to protect the material. Composite benches are also easier to clean and disinfect thoroughly, as there are no metal joints or crevices where moisture and bacteria can accumulate. The trade-off is that composite benches are typically not height-adjustable in the same way as aluminum benches with push-button leg inserts.

Is a backless bench safe to use in the shower?
A backless bench is safe for users who have sufficient trunk stability to sit unsupported — meaning they can maintain an upright seated position without leaning against a backrest. For users with good core strength and balance, a backless bench offers more flexibility in positioning and easier transfers from either side. For users with limited trunk control, weakness, or significant balance impairment, a bath bench with a back and armrests provides additional safety. Consult an occupational therapist if you are unsure which style is appropriate for your level of function.

Can this bench be used in a walk-in shower as well as a tub?
Yes. The RB670 is designed for use in both walk-in showers and bathtubs. For tub use, position the bench so that two legs are inside the tub and two legs are outside on the bathroom floor, allowing the user to sit on the bench and swing their legs over the tub wall — a common transfer technique for individuals who cannot step over the tub edge. For walk-in shower use, place all four legs on the shower floor. Confirm the bench legs are stable and non-slip on the surface before use, and use a non-slip bath mat under the legs if the floor surface is slippery.
