I can report that having a second (working) shower has been really useful. Having it's own water heating system means that both can run simultaneously without any problems. The one thing that made it a little tedious was having to squeegee down the floor after each shower and waiting for it to dry before using the loo or sink in there.
We had always planned to get doors in this room but as the size wasn't off the rack we'd need to get them custom made at a cost of around £700. For the sake of £700 my view was to endure a few months of sgueegee-ing. The builders said they might be able to find a cheaper supplier, somewhere around £500 but this didn't eventuate - and £500 + fitting was still going to be a bit of a whack on top of the already depleted bathroom fund.
Then Rob found a 90cm centre-opening bathroom door system on eBay - brand new for £90 including delivery. They arrived the next day. As the bathroom is 92.5cm wide it would mean having a 2.5cm panel or plinth on a wall to make up the shortfall, or putting in really wide rubber in the central join. Then Rob somehow had a genius brainwave and bought another bathroom door system the next available width up - 95cm. The builders fixed one half of the 90cm panels to the wall and one of the 95cm ones and lo and behold, it fits perfectly. You can't even tell that one of the panels is slightly wider as the sink & cupboard are in the way.
£180 worth of doors and £50 to install them means a £700+ job is done for £230! If you have a 92-93cm wide shower room and you need some doors we have a set here - get in touch.
These photos show the doors fitted and in action... The kids and I have had showers there this evening and there were no leaks or splashes even after three of us tried to make lots of mess. Happy days.
