Kartell K-VIT Nero Square Concealed Thermostatic Shower Valve with Diverter – Matt Black (SHO049NS)

Kartell K-VIT Nero Square Concealed Thermostatic Shower Valve with Diverter – Matt Black (SHO049NS)

The Kartell K-VIT Nero Square range is matt black metalwork with crisp, angular forms — the shower side of the Nero Square brassware. This is the concealed thermostatic shower valve with diverter, the two-outlet version.

What the diverter gives you

A diverter lets you run two outlets from one valve and switch between them — typically a fixed overhead drencher and a handset on a slide rail. One control for temperature, a second to choose where the water goes.

If you only ever want a single outlet, the single outlet valve costs less. But adding a second outlet later means opening the wall again, so it is worth deciding properly now.

This has to be planned before you tile

A concealed valve buries the mechanism in the wall, leaving only the control plate on show. The valve body must be set at the right depth and height before the wall is boarded and tiled. Too deep and the plate won't sit flush; too shallow and it stands proud.

A stud wall needs noggins to fix to; a solid wall needs chasing out. Worth reading the data sheet, linked below, before the plasterer arrives.

Thermostatic and WRAS approved

A thermostatic valve holds the temperature you set even if water is drawn elsewhere in the house, and shuts down if the cold supply fails — the safety feature that matters in a family bathroom.

It's also a WRAS approved product, meeting the Water Regulations Advisory Scheme standard for materials in contact with drinking water. Installers and building control officers do ask.

Living with matt black

Matt black shows limescale and water spotting more than chrome, and a shower valve sits in the wettest place in the house. Wipe it dry after use to keep it sharp.

Never use abrasive cleaners or limescale remover. The finish is a coating rather than plating, and harsh chemicals will dull or strip it. Warm soapy water and a soft cloth only.

What else you'll need

The valve is the control only. For a two-outlet shower you'll want the Nero Square fixed head and arm and the Nero Square slide rail kit, plus a square outlet elbow to feed the handset.
