Finally had a free day to play with the Expanda and make a start on the shower.
Fitted the base, couldnt go centre of shower for drain as there was a cross member under the floor so positioned it where I could join the sink drain to it under the van while all protected by cross members. Used a pop up drain so we can plug the bottom if needed.
I 'peened' the edge of hole in base so drain would sit flush too.
Just gotta work out what to use for shower walls, seen people use 'whiteboard' panels, cheaper than laminex and just as good apparently, will investigate at bunnings sometime.
I also have a small corner sink coming from Europe so cant do any plumbing till thats here and mounted. Planning on using one mixer tap and putting a thread on the end so we can screw a shower hose onto it. Keeps it simple.
And lastly, gotta work out a door, a light one.
Also reused one of the wardrobe door/mirrors on front of shower to keep wifey happy.
