Concept 1, the sliding door is opening the wrong way, ie: the first thing you will see is the WC, also it's much better to have a hinged door on a bathroom and it should open back against the WC. ( I know you had it the door sliding that way because of the toilet plumbing)

The storage cupboard I would move across to the vanity side and allow access into the shower from that end with out a door, both shower heads coming off the long wall, not a good idea to have a shower head up against a window cheers

Concept 1. By far the best.

I would add a short wall to disguise toilet. Potential to have the short wall as a storage shelf - push toilet across towards shower for extra space.

Centre the vanity to the wall - centre the bath to the window. Towel rail is a bit close to shower and bath.

Concept 2 is ok except for toilet onto shower. Could rotate toilet around to the wall and then have a longer shower with a side door. Shower could be 1500 long.

One thing I dislike with any layout is looking straight at a toilet when opening a door, unless its a WC obviously. The second one is looking straight at the shower and thirdly which can be a tricky thing to work around is looking straight at a mirror when entering a room.

Be wary of windows and the reveals in showers, they can be tiled and waterproofed but try to design around this first.

If you decide to go with a wall hung vanity be sure to note this clearly on the plans.

Usually plumbing for the waste will need to be routed through a wall (or a flashy chrome waste pipe needs to be purchased) as well as the wall itself may need strengthening to take the hanging weight.

This is how I visualize concept 1 without knowing what shape the windows are.

Why can't you keep the toilet in a separate room? Therefore two people can use the rooms in privacy.

Hi dreamer, great question! The client requested for a spacious bathroom and the wall between the toilet and bathroom has been damaged by water and termite infestation, as such, the wall will be demolished and we’ll be opening that space up to 1. Remove the damage entirely and 2. Make a bigger space.

Good luck. My concern is none of the options use the windows properly. I would place the vanity on the right hand wall, then the bath central to big window. Avoid window in shower as begging for more waterproofing cost eg replace window?
Need a low or full height wall out to 800 next to toilet for toilet roll holder. This could form one side of shower. Avoid having toilet roll holder too close to rear of toilet. It needs to be in easy reach not beside body.
The storage shelf seems random. Prefer to use it to extend vanity to 1800.
Shower top left corner with towel rails opposite, to left of bath.
Consider using a back to wall bath as it frees up floor space but gives look of freestanding. Depends on window level.
Don’t forget a robe hook near shower

OK: knock the walls all out and make one rectangular space. 2.5 x 4 m ish with free reign on windows too! Assume it is a family home where kiddies might like to use bathroom all at once but want privacy too (if not as littlies definitely later when teenagers) Install two (OR three!!?) hand basins &or vanities beside door. Leave loo where it is (better $$), Put shower in other corner and center bath in space between opposite door and bench or vanity, create dividers (walls or frosted glass and sliding doors) to close off loo and shower from bath. Toilet room has window, match a window over bath one end and add a hand held shower rose too for crowd scenes and put same size window (please) between shower and vanity assuming that is outside wall. It is out of shower, by vanity, casting light and view thro whole area. Bath has light and ventilation, toilet room too has light and vent. Silly me it is now a powder room! At least 2 people can be using this space simultaneously with privacy and a third or giggling kiddies in bath too. Hope this makes sense…...it would work for a family. Cheers Margot

Definately make the loo a separate room. Much more practical!

I would use concept 3, BUT two changes: (a) move the entry door to 1000mm from left wall (similar position to where you have slider in Concept 1), and (b) move shower to where you have it in concept 2 but have a 900 long wall or nib wall for the entry door (hinged) to open onto. Benefits of this design would mean you utilise the current window placement properly, you have a hinged door, toilet has privacy and also you don't need to move the toilet plumbing. From a client perspective, the last point is very important as it will save money. Good design should always think about cost/benefit ...

I preferred your first option 1 where the door opens back against the toilet, concealing it from view. This is especially handy if you have a mother like me who never closes the bathroom door. In our new bathroom, she has to close the door to get to the loo! Excellent strategy!

Siriusky, excellent ideas. We have a walk In showers area, no door. It’s fantastic,saves a lot of cleaning and is great for universal access (aged or disability). I meter is a useful width as you can put a chair in if necessary.

Concept 1 with changes.

Shower to opposite (LHS ) wall and remain full length.
Toilet to remain in original position under RHS window.
Bath centred between these two and close to the wall, can skylight be pushed further out above bath?
Double vanity opposite bath on internal wall.
Door on RHS of internal wall opening straight onto toilet.

I agree with kylie_davidson13 with moving the door to a hinged door in position of Concept 1 and the shower placement of Concept 2. These changes both increase privacy for someone using the toilet or shower. I would also try to centre the bath as much as possible - perhaps you could move the vanity to the opposite wall (to be the wall same as the doors) so that the bath can be the real hero and what you see if the door is left open.
Good luck

Silly thing: I did the drawing but didn't send it to you. !! See what you think of this layout. As I said before it really depends on the context of the house, number of people etc. but for a crowd scene this plan would be great. Let me know what you think and how you go...it is always very interesting! Cheers Margot

A bit unrelated but where are you studying? I'm looking at doing a design course and I want to learn how to sketch, draw plans etc.

I did my Arch Draft course at Holmeglen TAFE where we did learn manual drafting, which I love. Not sure if it might all be on CAD. Shame because the pencil and paper is therapeutic and somehow creative in a way the computer most definitely is NOT! Good Luck!

Thanks I did my diploma of building and construction there too might give it a shot, really would like to learn both to be honest

If they don't teach it or wrong timing, maybe we can work out something together. What direction do you live?

I'm based in box hill area, yourself?

given the choice i always prefer a separate toilet and would keep the original bathroom and toilet layout, include the small hallway in the toilet and use the savings on new new taps, light fittings, paint and a 1200 x 900 shower in the same location with plumbing extended through the wall for a tiny handbasin for the new powder room.....keeping in mind that not all clients will have the budget for a total rearrangement and the challenge will be to see what can be salvaged and what needs updating

Budget Bathrooms Melbourne, my course is through Open Colleges however (sadly) they don't teach us in great detail about technical drawings. We spend the first 13 modules, manually drawing our concept designs, and from Module 14, we begin to learn AutoCAD and also 3D modelling on SketchUP. After I complete the course, I am hoping to look into architecture at University, as they teach you everything about technical drawings however, Kitchen and Home Sketch Design's referral of Arch Draft course at Holmeglen TAFE sounds interesting! Best of luck with your extension of education :)

I remember this assignment!

It’s all about the client brief, did you have to design the walk in robe aswell?

My client was a male CEO / business executive so I focused on:

1. Modern High Quality finishes.
2. Positioning the toilet for adequate ventilation and ensuring it could not be seen.
3. the use of 1800 High internal walls to partition the space.
4. Ensuring the vanity was positioned so it had adequate natural lighting.

I also remember a part of this assignment was clarifying Information with the client (teacher) to ensure there was no miscommunication.
