Hi cjones2011, It's a bit late, but do you have any photos of the finished result?

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.

do you mean an electric hot water system using tank water?? we have just installed an air sourced electric hot water heater using tank water but the fine print says that the warrantee would not be honoured if the PH of the water was above or below average so we had the tank water tested and found that it's relatively simple to adjust the PH of the water using the same technique as for a swimming pool (our local pool service is quite happy to make a mix to be be added to the tanks if/when necessary and we already had a water filter connected with the pump BUT we've been told that if the water tanks are in a built up city area subject to industrial air pollution it's much more difficult to maintain the correct PH

En-suite layout is fine, Looks like you have a double hung window with a slightly lower sill to the vanity height. . I’d put a stool in front next to shower screen. Update vanity and top and splash back, maybe lowering mirror. Could put a niche in the side wall if want extra storage. Could change mirror to a cabinet, even if it protrudes, mine does, A smaller basin would increase spaciousness and bench space. Can also increase depth of vanity, to 550. Replace floor tiles if you want but I’d leave shower if you want to keep costs down. otherwise retile to full wall height will improve look. Could add a pendant light over left side of vanity
