Cortez (Insert Spa Bath with Tile Bead) The Cortez has the minimalist approach to design but by adding tiling beads to the bath’s perimeter, it can be used as an inset bath. This means that it can be fitted into the wall studs rather than spaced away from them as is required for an island bath with no tiling beads. Optional Ezi-Frame available. Sizes: 1520 x 765 x 450mm – 136 litres / 1670 x 765 x 450mm – 154 litres
