Create a True Barrier-Free Shower
Low Profile. ADA-Compliant. Easy to Install.
Transform your bathroom into a seamless, curb less shower space with the HYDRO-BLOK Floor Lowering Kit. When paired with a HYDRO-BLOK Single Slope Shower Pan, this system lets you achieve a barrier-free, ADA-compliant design quickly and efficiently — no complicated framing required.
Engineered for Precision & Performance
The floor-lowering brackets allow your subfloor to sit flush with the joists, creating a perfectly even transition between the main floor and your shower area. The result? A low-profile, accessible entry that looks beautiful and performs flawlessly.
Ideal for both I-Joists and dimensional lumber, these brackets attach directly to the top chord of the joists and parallel wall studs for maximum strength and stability.
