Choose how the counter will be used
A longer single bowl leaves space for toiletries; a double bowl provides two washing positions. E121 and E121 Double both have a listed 1210 × 465 × 170 mm footprint, but their bowls and waste positions differ.
Coordinate the finish
Discuss white, black or another glaze with the cabinet finish. Screen images are an initial reference. Confirm the model-specific finish availability and approve a physical sample before ordering.
Confirm every bathroom separately
Provide cabinet and plumbing drawings for each bathroom. For offset models, specify left or right bowl position and check it on the original drawing. Requested length changes require confirmation for the exact model.
