Hi Diana , You will need to give the measurements of your bathroom and what is underneath the floor ( another level / slab / undercroft ) . Also what room is on the left .

Sorry yes I should I have said, I don't have the exact measurements but the existing vanity is exactly 1m, so that gives you an indication of the room size hopefully.

The doorway on the left is the WIR and this is on the ground floor of the home. The house is on stumps (you can crawl under it).

The Laundry is on the other side of the room (the wall behind the toilet)

all bathroom renovations are much more expensive that we would like but not ending up with the best result is a waste of money ..thankfully you have access under the floor so there shouldn't be extraordinary extra costs of moving any fixtures but we need the dimensions of the rooms to be able to make realistic suggestions...if you don't have access to measure the rooms, windows and doors can you post a whole house plan showing dimensions of other rooms and are you attempting to add value for resale of for personal use?

Sure, here's the whole house plan oklouise.

This would be for personal use

If it was me I'd switch the window to a highlight one but that's fairly costly.

if the ensuite is at least 2000 x 2400 preferable more an under 1500 wide vanity with matching mirror doored wall cabinets on the opposite wall (preferably allow a gap between vanity, new wall coverings and shower), install a new neater looking toilet closer to the outside wall (allowing at least 800 width total toilet space) with heated towel rails, shelves or a mirror above the toilet to improve the view from the bedroom and use a 1200 wide shower stall with sliding door as there isn't enough space for a walk in shower and when you're ready to plan a new kitchen consider losing the formal dining area and extend the kitchen sideways

Yes CP ideally that would be best but blows my budget so trying to work with what is there already.

Thank you oklouise, my thoughts were along the same lines. The towel rail above the toilet I hadn't thought of. Thanks for the kitchen suggestion too, we were thinking of doing that few years down the line.

Btw guys, you'll notice in the photo that the waste pipe for the toilet comes out of the wall. It looks terrible. Do you think this is going to be a huge cost to fix?

Looks like toilet was rotated at some point. Change plumbing to under floor. Move vanity to opp wall and make single basin vanity and 1200 shower along that wall.

Thanks everyone for your feedback, here was the end result. Space feels much more spacious with uninterrupted natural light flowing in.
