The flat version of the 1200x900x1200mm 3-sided liner covers all three alcove walls with smooth, uninterrupted acrylic. On a 900mm-wide back wall, the flat option is often the practical choice because the mixer valve and shower head may not leave enough room alongside a moulded caddy.
Narrow Back Wall Considerations
With only 900mm of back wall width, fixtures and fittings compete for space. The flat surface lets you position your mixer, shower rail, and any storage accessories without working around a fixed caddy location.
Dimension Matching
1200x900x1200 means the two side walls are 1200mm deep and the back wall is 900mm wide. Confirm your alcove measurements match this configuration before ordering.
Material and Installation
2mm sanitary grade acrylic. Seamless one-piece folded construction. Bonded to prepared walls, silicone sealed at all edges. Standard 1950mm NZ shower height. Professional fitting recommended.
