I have an "easy fit" "click build" Insignia Platinum 900mm steam shower. The shower cabinet needs putting together before installing. Existing shower cabinets need dismantling (20 minute job) old plumbing connections can be reused for the new shower. Take away dispose of old shower and packaging from new shower. You only need to supply 3 1m length flexible water tubes and plumbers mait - everything else supplied with new "flat pack" shower cabinet
