Fitting a shower enclosure at the end of bathroom?

tallac

I have a bathroom which is about 235cm long by 125cm wide. I'd like to fit a shower enclosure on one end of the bathroom so I can use 3 sides of the bathroom wall for the showering area with a single shower enclosure panel that is 125cm wide (effectively going from wall to wall) with a sliding or pivot door. The depth of the shower is more flexible but I was thinking around 90cm (or maybe 100cm). However, the width of the shower has to be exactly 125cm so that it can span from wall to wall. I hope I've explained this clearly.

I've seen shower trays/enclosures that are 120cm x 90cm and some that are 130cm x 90cm but I haven't seen any that are 125cm x 90cm. My question is, are there shower trays/enclosures that have a certain degree of flexibility to allow it be installed in +/- 5cm such that it can accommodate the exact width of my bathroom? Or will I need to get a made to measure option?

I know there is the option to go for a wet room type bathroom but I want to explore options with an ultra slim line tray (or floor flush tray) and having a complete wall to wall enclosure.

I don't have very deep pockets so value for money is quite important. Can anyone suggest what solutions are available to me?

Building a 90cm stud wall to bring the enclosure down to 120cm in width would be a cheaper option than a made to measure tray.

125cm is also a really awkward measurement for glass screens, so you'd end up with a similar problem.
 

You could use the extra 5cm depth in the wall to hold a
recessed shower valve, or maybe even a recess for bottles - if one existing wall is made of studwork and budget allows.

We have an awkward sized shower.  The bathroom is 154cm side to side, and the previous owners had a mosaic tiled floor done in the shower to avoid the problem.  I would not recommend this, as the mosaic is a nightmare to keep clean.  It's also been badly laid, so the water puddles in places, and doesn't slope towards the drain. 

We're about to have it ripped out and, as Doozergirl has suggested to you, are having a false wall built at one end to bring the size to 140cm, which gives us a lot of off-the-shelf tray and door options.  We're using the empty space in the false wall to put in a 100mm deep recess for bottles and to allow easy running of new pipes.

Thanks @Doozergirl and @scottishblondie that's an excellent idea and seems like it's much more cost effective. I was looking to have an inbuilt shelf for shampoo anyway so this will make it easier too :-D
