I think the larger shower is a great idea. My "newish" house had a big ensuite but was fitted with the standard 800x 800mm tray, which is cramped, especially on elbows! So I've ripped it out and have bought a new 800x 1200 offset tray, new enclosure and accessories etc. I plan to reposition (the original locations were badly planned) the WC and WHB to optimise the space of the ensuite and hopefully should have a "luxury" ensuite by the end of it all. The only problem is trying to motivate myself to actually get stuck into the job.......
