Abstract: A drainage system (1) for installation in a wet area such as a shower stall. The drainage system (1) comprises an outer drainage conduit (2) adapted to extend within a subfloor (100) of a wet area and an inner drainage conduit (3). The conduit (2) comprises a rim (20) and a pipe body (21). The inner drainage conduit (3) also comprises a rim (30) and a pipe body (31). The rim (30) and pipe body (31) are nestable within the outer drainage conduit (2). When nested, the pipe bodies (21, 31) are adapted to be connectively sealed together using sealant, the rims (20, 30) are adapted to hold a waterproofing membrane (107) between the rims (20, 30) and to be connectively sealed in a water-tight manner to the waterproofing membrane (107) using sealant or, in the absence of a waterproofing membrane (107), the rims (20, 30) are adapted to be connectively sealed together using sealant in a water-tight manner.
