2.5 PREFORMED, PREFINISHED SHOWER BASES AND ENCLOSURES
Materials used in the manufacture of preformed, prefinished shower bases and enclosures shall be such that the finished product is waterproof.
注意：没有在规范中发现预制防水墙体的条款，所以采用宣称防水的预制卫浴墙体，仍需要符合规范中关于墙体部分的防水要求。
3.3 FALLS IN FLOOR FINISHES
Where required, falls in floor finishes shall allow all surface water to drain without ponding except for residual water remaining due to surface tension.
For general bathroom floor area, the minimum fall to the waste shall be 1:100.
1 For information on falls in the floor finishes, see Appendix B.
2 For information on the laying of tiles to enable them to drain without retaining water, see AS 3958.1.
Falls in shower floors shall be sufficient to prevent—
(a) surface water from being retained on the shower floor (except for residual water remaining due to surface tension); and
(b) water from discharging outside the shower area.
For shower areas with a vertical separation between the shower area and the wet area, such as a shower screen, hob, step-down or water stop, the fall to the waste shall be 1:100.
As a minimum for other shower areas, the fall shall be a minimum of 1:80.

在这种情况下，干区可不做防水，只需使用耐水（如瓷砖）的材料。
以使用最多的水泥纤维板为例，看看国外的材料供应商（哈迪板）做了哪些工作来服务客户，以资借鉴。
