This weekend we did a little more plumbing and set the shower waste pump into the floor ready for when we get the shower tray,
Below. Shower pump set into the floor. I think if I was doing this again I would probably fit a gulper instead of a sump pump as the lid isn't water tight and will over flow without warning if we ever forget to switch it on, with the gulper I imagine paddling around in water would be enough of a reminder to switch it on quick.
A bit more of the floor will need to be cut away when we get the final shower tray outlet position.
