As expectations rise for inclusive, future-ready housing and public buildings, the way we handle water in wetrooms is under the spotlight. Traditional drainage methods, such as centre waste gullies and sloped floors, often compromise layout, aesthetics, and usability. Jesani’s stainless steel linear shower and door channels have been challenging that model since 2010, offering a refined, level-entry system that prioritises both form and function.

Rethinking drainage: Linear logic over gully limitations

In conventional bathrooms, water drainage has long dictated the floor design — often resulting in complex gradients, awkward tile cuts, or restricted layouts. For accessible bathrooms, these challenges become critical. Sloping surfaces can create instability, while traditional centre wastes complicate level-entry transitions.

Jesani solves this by removing the need for multiple gradients or central drain points. Due to the patented flanged design, their linear shower channels sit flush with the floor, allowing consistent levels across the wetroom. This simplifies installation, enhances safety, and gives designers complete control over the layout — whether for wheelchair access, walk-in use, or multi-generational living.

Door channels: A smarter safety net

Architects designing accessible bathrooms must consider more than mobility, they must also manage risk. Internal flooding from accidental overflows can create serious hazards, especially for vulnerable users. Overflows can also result in expensive repairs — with residents needing to spend time out of their home while these are completed. 

The patented Jesani Door Channel is designed to sit at the bathroom threshold and protect the space. It stops water escaping from showers, baths, or basins and drains it directly out the soffit, exterior wall or if using a 65mm outlet, back to the greywater — all without the need for sloped flooring.

Importantly, if using the security-secured grill option, the drain is nearly impossible to block, making it a practical choice for social housing, high-risk facilities, retirement living, and public access facilities.

Stainless steel that performs — and lasts

All Jesani channels are fabricated from high-grade stainless steel, delivering durability, hygiene, and long-term value. Unlike plastic components that degrade or discolour, stainless steel maintains performance under heavy use and remains resistant to mould, odours, and impact.

This has made Jesani ideal for both residential and commercial projects, including hospitals, care homes, and multi-unit developments where compliance, safety, and visual integration are non-negotiable.

Compliance and confidence for architects

Jesani’s products support NZS 4121:200, are LifeMark approved and align with universal design principles. Their BRANZ Appraisal offers assurance of tested performance, and WaterMark certification is underway in Australia, where regulations around accidental overflow drainage are tightening.

With New Zealand’s ageing population and an increasing demand for accessible homes, there’s a growing focus on in-home safety, Jesani positions specifiers to deliver high-performance wetroom solutions that are elegant, efficient, and future-proof.

Design without compromise

Architectural detailing should never be undermined by technical limitations. Jesani channels provide the freedom to maintain a continuous floor surface, support under-tile heating, and uphold aesthetic integrity — without sacrificing drainage effectiveness.

They also support sustainability goals, with 100% recyclable materials, minimal maintenance requirements, and long lifespans, making them a smart specification for Passive House and green building projects.

Jesani: Designed for the way we live now

From bespoke homes to high-density housing and commercial requirements, accessible bathrooms are becoming the standard — not the exception. Jesani’s linear drainage systems enable designers to lead with accessibility in mind, rethink conventional limitations, and deliver wetrooms that are safe, stylish, and built to last.
