Fix a cracked or unstable toilet base without replacing the whole unit. The Thetford 42138 Aqua-Magic Style II Toilet Base (Bone) is the high-profile OEM pedestal/base assembly only—engineered to match the original footprint, height, and mounting pattern of Aqua-Magic Style II high-profile toilets.

Key Features
  • Genuine Thetford OEM base for Aqua-Magic Style II – High Profile
  • Bone finish to match existing Bone Style II components
  • Designed for single-pedal flush; compatible with water-saver linkage where equipped
  • Direct-fit: preserves original bolt pattern and rear water line routing
  • Perfect when the base only is damaged; reuse the bowl, seat/cover, and valve
