Shower floor former assembly

A shower floor former assembly 10 is provided which comprises a shower floor former 12 having a non-circular waste-plate receiver 18 and a drain waste plate 14 which is dimensioned to be receivable in the waste-plate receiver 18. A centre point (CWPR Figure 2) of the waste-plate receiver 18 is offset from a centre point (CSFF Figure 2) of the shower floor former 12. The drain waste plate 14 has a drainage aperture 30 through a centre point (CDA Figure 2) of the drainage aperture 30 and is offset from a centre point (CDWP Figure 2) of the drain waste plate 14. The drain waste plate 14 is receivable in the waste-plate receiver 18 in a first condition in which the centre point (CDA figure 2) of the drainage aperture is offset relative to the centre point (CSFF Figure 2) of the shower floor former 12. The drain waste plate 14 is also receivable in the waste-plate receiver 18 in a second condition in which the centre point (CDA Figure 2) of the drainage aperture 30 is coincident with the centre point CSFF Figure 2) of the shower floor former 12. A later embodiment relates to a method of installing said shower floor former.
