An all weather outdoor shower is easily done by locating the mixing valve inside the house and use a coupling shaft to locate the handle on the outside. You must use a standard tub type lower faucet (with the pull up to activate the shower) to allow the system to drain out when the shower is done. You also have to make sure everything slopes in direction of the water flow. We live in Bancroft Ontario so winters are well below freezing and we have been showering outside for 3 winters. Only issue we have is the shower head will freeze so we typically remove it after a shower or shower without it on when really cold. The system has worked well and it helps that nothing special needs to be done by anyone. no inside valves to close etc. Just turn off tap and everything drains.

I won't bother with lattice, barrels are partially obscured from the street by fencing and if I put it up I would have to work around the lattice in order to turn the valves for water. If I can just make better use of collected water I'll be happy. We are at the end of our growing season so I should be cleaning up the garden and putting it to bed for the winter, just can't seem to get motivated. We had our first frost last week. Usually, our average early frost date is 1 November. I got almost no produce from garden this year, but there is always next year. Chookchook2 I've seen some of those decorative metal panels and they are gorgeous, sure hope your budget will allow you to get some before too long. Most of our state has been on fire for a good part of the summer. The closest is across the river from us and they have been battling it for almost a month. Some friends have had to evacuate repeatedly. We've only been concerned once, a small grass fire on our side of the river on a day we had wind gusts up to 65mph. Fortunately, it was put out quickly. Australia and New Zealand have both sent firefighters to help with the blazes. I can't begin to tell you how appreciative we are. The closest fire was fought for almost a week by local volunteers only as there were no other resources available. They were all on other fires. The Army National Guard (reserve troops) were called out to help with support duties and for the first time ever the federal Department of Natural Resources (DNR) asked for civilian volunteers to help with non firefighting tasks, cutting fire breaks, moving supplies etc.

Thanks :) Yeah decided to go with tile. So sand cement is ok over existing tiles if I prep them first? Only problem is, the new pad can only be about 30mm at it's thickest (leaving up to 15mm for tiles) otherwise it'll end up being higher than the hallway floor. So I either need to make the fall shallower or not bother with the waste and make it all level. If I made it level, could I use levelling compound at that thickness or would deck mud/sand cement be the best option? Also, should I be putting in mesh for strength? (I know I should (and will) ask the local hardware what they suggest, but it's great to have suggestions from the Houzz community also)

We have a 900x900 shower and it's plenty big enough. Neither of your proposed layouts looks that great, to be perfectly honest, sorry! In the first layout, you could improve it quite a lot by swapping the toilet and vanity (centre the toilet under the window on the bottom right of the picture if possible), and having the shower door on the other wall (beside the door). Then, you could have a towel rail on the wall beside the door (i.e. behind the door when it's open), which would be accessible from the shower but hidden when the door was open. An 800x1200 shower might be a good size for your space. You'd have to choose a toilet that doesn't protrude too far, plus a narrow vanity. With that layout, you could have a long but narrow wall-hung vanity, with a big mirror covering the wall between the windows, which would make the room feel bigger and would give a good amount of storage.
