I am struggling to find any pictures of where someone has the shower fittings higher than their shower screen to see how odd it actually would look like. One of my 101 learnings about getting the wrong tradesperson to "project manage" my bathroom renovation (until he went MIA), was not voicing louder to the plumber's assistant who actually did the shower connections, that what the "project manager" had suggested for heights of shower connections was way too high. I had actually double-checked it on the previous weekend with a friend and we both thought that it needed to be lowered by 100-150 mm, but when I said this to the "project manager" he ignored me as did the plumber assistant who made the connections....I know how a handheld shower only (which is all I wanted) fitting that is at 2070mm in one bathroom and 2020mm in the other bathroom. As there is no shower rail (because I wanted things to look simple), I get my daily stretches just to reach the handheld shower.....I am happy with the progress of my bathroom, except for all of the stuffups caused by this particular "tradesperson/project manager". We live and learn....I can't do anything about what has happened, but can only minimise the impact where possible and learn from all the things that went wrong, if there is ever a next time. I should make a list of the learnings once bathroom is finished.

we also like the look of the back to wall shower grate and have not been able to find cheaper and longer sizes are much more expensive but we have one shower with the grate against the wall and another shower with a shorter shower grate across a doorway and despite preferring the look of the grate along the wall the smaller one at the outside of the shower is more efficient, cheaper and much easier to clean

the last option with shower and toilet either side of the window and hinged entry door opening towards the laundry cabinet... hinged door is cheaper and offers more privacy and solid core hinged doors will improve sound reduction and the back of a door can support extra towel rack and/or clothes hooks and the tall window needs only be same as top of door height (about 2.1m) and if necessary simple hinged doors on the laundry nook will use the least space and are only open occasionally

Um, why? Looks difficult to clean, difficult to access, and impossible to safely bath kids. I would avoid at all costs. No prospective real estate buyer ever said "I love the combined bath and shower arrangement" as they are generally universally hated, especially if there are toddlers, or elderly in the household . If you do go with this dangerous proposition then make sure you have plenty of well anchored grab rails so you don't knock your teeth out when your head hits the floor. Have a look at the Posh Domaine Shower Bath, which has a flatter, squarer base, rather than your traditional bath Best of luck, Dr Retro of Dr Retro House Calls and Dr Retro Virtual Visits.
