Onyx Nebbiosa is a subtle, light marble decor built around an intricate pattern of mid-grey veining within a mixture of light and dark greys, for a calmer, more understated look than a bold statement marble. The Polished finish adds a soft sheen that keeps the whole surface feeling light and airy. Like every panel in the Elite Collection, it's fitted with tongue and groove joints and sleek post-formed edges for a completely seamless finish — no grout, no sealant lines breaking up the pattern, just one continuous surface from floor to ceiling.
100% waterproof

Where this works
- Full wet room wall coverage — panels can extend beyond the bath/shower area for a co-ordinated look
- Can be cut and combined to form custom waterproof windowsills and shower niches
- Not designed to carry the weight of taps, shelving, or fittings — these must be fixed through the panel into the wall structure
