This will be a long story (sorry!)
I currently have no shower in my bathroom. This is somewhat inconvenient - my compromise is the absence of shower is to use the one at the gym (no good if I fancy a shower in the early hours/late at night!) My lovely bf will only stay at mine infrequently because he hates baths - when he stays over has to get up extra early to go home first and shower at his before work). This is far from ideal, so I really need a proper solution.
Unfortunately there's no cheap interim fix, as my bath tap is a sort of waterfall mixer type thing so I can't even get one of those cheapo attachments as a temp measure!
I have a 'space' in my bathroom for a shower. Said space is marine ply boarded, has a drain, and basic hot/cold pipes but needs tiling. The original plan (when Ex started and half finished the bathroom) was that because it is a narrow, cubicle shaped space, we would tile walls and floor and have a lip/step up/down - so that the water didn't end up all over the rest of the floor.
Have had a few tradesmen round to look at it. All said I can't tile the floor as 'it will leak'. One said I would need a specially made shower tray, because the space is narrow and the drain is in one corner and that would cost £500 alone. Another quoted £2000 for the job (I already have all the tiles and the shower). A third said I wouldn't get a tray to fit, and it 'wasn't worth' trying to put a shower in the space because it would be too narrow to be useable 
So...any thoughts/words of wisdom? Does it sound like it IS possible, and if so, how much should I be expecting to pay?
