Micro-mineral concrete bathroom sink worktops can be built using various substrates (WEDI, cellular concrete blocks, water resistant chipboard…), which are then covered with Smooth Finish Mortar. Another solution is to build single-piece concrete units using Ultra-High Performance Concrete (UHPC). Sink worktop protection is essential for hygiene and greatly facilitates bathroom cleaning and maintenance.
