The TECEbase WC frame with the Base 320 flushing system is an ultra-slim wall-mounted toilet frame with an overall width of just 32 cm, specifically designed for space-restricted installations. With a mounting height of 112 cm, this compact frame system offers several installation options, including corner installation, drywall installation in front of the wall finish, and installation in walls with metal or wood profiles. The pre-assembled flushing technology features an innovative three-way shut-off valve in the Base 320 flushing mechanism, providing immediate 7-liter flushing capacity without waiting for tank refill. The beveled tank corners optimize corner installation configurations while maintaining the minimal 32 cm width profile. This system is compatible with standard market plug adapters, eliminating the need for additional seals and reducing installation errors. The frame supports compatibility with over 200 TECE flush buttons featuring Easy-Fit technology for tool-free installation. Wall mounting brackets for masonry walls are included, while a separate purchase of a corner mounting set is required for corner installation. The TECEbase system represents a successor model to earlier slim frame installations, offering improved space efficiency and installation flexibility for modern bathroom designs where minimal space requirements are crucial.
