A wall-mounted basin mixer is one of the few tapware decisions you can't easily undo. Once the wall outlet is roughed in behind the tiles, the spout's reach is fixed for the life of the bathroom — get it wrong and you're either splashing water against the back of the basin or watching it clear the front lip onto the vanity top. Unlike a deck-mounted tap, there's no swapping it out later without re-opening the wall.
Nero's Kara range is one of the few sets in the catalogue that actually gives you a choice here: the same Kara Wall Basin Set is sold in two spout lengths, 180mm and 217mm, so you can match the reach to your basin rather than the other way around. Here's how to pick between them, and what to check if you're specifying a different range that doesn't offer the option.
Why spout reach matters more on a wall mixer
On a wall-mounted set, the spout's horizontal reach from the finished wall face is what determines where the water actually lands. Measure from the wall to the point you want the water to hit — generally the centre of the basin, a little forward of the back wall of the bowl — and that's your target reach. Basin depth and mounting height also play a part: a shallow above-counter vessel basin set further off the wall on a custom joinery top needs more reach than a compact wall-hung basin sitting close to the tiles.
Get it wrong in either direction and the fix isn't a five-minute swap. The mixer body's inlet is plumbed into the wall cavity, so a spout that's too short or too long usually means re-chasing the wall to move the rough-in point.
Nero Kara: 180mm vs 217mm
Both Kara Wall Basin Set spout lengths share the same build: brass construction, a single-lever handle over a ceramic disc cartridge, a universal G1/2" connection, and a WELS rating of 6L/min at 5 Stars (WELS registration T30974). Both come in the same five finishes — chrome, matte black, gun metal, brushed nickel and brushed gold — so the finish decision is separate from the reach decision.
Kara Wall Basin Set, 180mm spout (SKU NR211707a180, from $167.20 in gun metal, $240.35 in chrome) suits basins mounted close to the wall — standard inset or semi-recessed basins where the bowl sits not far off the tiled finish face. It's the tighter of the two reaches, so it's less likely to overshoot a compact basin.
Kara Wall Basin Set, 217mm spout (SKU NR211707a217, from $250.80 in chrome) adds 37mm of extra projection. That's the difference that matters for above-counter vessel basins on stone or timber tops, where the bowl itself sits proud of the counter and further from the wall than a drop-in basin — without the extra reach, water from the shorter spout can land against the inside back wall of the bowl instead of the centre.
If you're not sure which you need, measure before you order rather than after the wall outlet is set: hold a tape from the intended wall finish face to the centre of where the basin will sit, and compare that figure against the two reaches above.
Not every range gives you the choice
It's worth checking before you commit to a range, because not all of them offer a second spout length. Nero's Mecca Wall Basin Mixer, for example, ships in a single fixed reach — a simpler decision if your basin is a standard fit, but not one you can adjust if it turns out to be too short or too long for the installation. If reach flexibility matters for your job, the Kara range's two-length option is the more forgiving spec.
Both Kara spout lengths, and the full Mecca range, are available to browse in our Nero Tapware collection and the dedicated Mecca collection, alongside the wider basin mixer range. For accessible bathroom installs with their own tapware requirements, see our guide to AS1428.1 compliant lever-operated basin sets.
Frequently Asked Questions
How do I measure for spout reach before rough-in?
Measure horizontally from the finished wall face (allow for tile thickness, not the bare stud or brick) to the centre of where the basin bowl will sit. Compare that figure to the spout's stated reach — 180mm or 217mm on the Kara range — and choose the closer match, erring toward the basin's centre rather than its back edge.
Can I change the spout length after the wall outlet is installed?
Not without re-chasing the wall. The mixer's inlet is plumbed into the wall cavity at a fixed point, so the spout length needs to be locked in before tiling and rough-in, not adjusted afterward.
Do all Nero wall basin mixer ranges offer a choice of spout length?
No. The Kara range offers both 180mm and 217mm options in the same five finishes. Nero's Mecca Wall Basin Mixer, by comparison, is sold in a single fixed reach, so check the spec sheet for your chosen range before finalising the rough-in measurement.
What's the WELS rating on the Kara Wall Basin Set?
Both spout lengths are rated 6L/min at 5 Stars under the Australian WELS scheme, registration number T30974, and use a ceramic disc cartridge for the handle.
