Casa

Casa brings together the components needed to build a tiled wet room or bathroom from the substrate up. The range covers stainless steel linear drains and tile drain inserts for level-entry showers, tile-ready shower bases in centre and offset drain configurations, backing boards for wall and floor lining, and recessed niches for shower storage.

Underfloor heating is also part of the Casa range, with heat coil wire, digital touch screen and smart WiFi controllers, a Cablecheck earth leakage fault indicator, and red duct tape for securing cable runs during installation. Hebel blocks round out the collection for shower hobs, and wall builds ahead of waterproofing and tiling.

The range is built around fast, tidy installs in wet areas, with components designed to work together across a single project rather than being sourced piecemeal. Linear drains and tile inserts are matched to suit level-entry detailing, while backing boards and Hebel blocks provide a stable substrate for tiling over framing or masonry.

As with any wet area build, Casa components should be installed alongside a compatible waterproofing membrane and to the relevant New Zealand building code and manufacturer instructions. For heated floor systems or non-standard shower layouts, it's worth confirming compatibility with the Surtec technical team before ordering.

Orders ship across New Zealand, Australia and the Pacific Islands, with free shipping available on orders over $200.

 

Frequently Asked Questions

The SMART controller offers WiFi connectivity for remote or app-based control of underfloor heating, while the touch screen controller is operated directly at the unit. Both work with Casa heat coil wire, so the choice comes down to whether remote control is needed for the project.

Cablecheck is an earth leakage detector used to test underfloor heating cable continuity before, during and after installation, helping to confirm the cable hasn't been damaged before it's tiled over.

Yes, Hebel blocks are commonly used to build shower hobs and internal walls ahead of waterproofing and tiling, giving a stable, workable substrate in wet area builds.

The red duct tape is used to secure underfloor heating cable runs in place on the substrate before the heating system is tested and the floor is tiled over.

The Linear Grill is the grate component only, while the full Linear Drain includes the drain body as well. Check which is required for a project, as some installs use an existing drain body with a replacement grill.
