Do you need to keep the bath? If not, then to keep your stained glass window intact/remove issues with moisture from shower - shift vanity along the 2.71 wall into the space currently occupied but the toilet and divide the space along the 2.04 wall between shower and toilet (shower opposite entry door into the room and toilet closer to the window.

is there another bathroom or toilet in the house and is the existing bathroom functional? do you have plans for other improvements?...

There is another bathroom in the house. But it is a necessity that I keep this bathroom as this will be the one the kids and guests in the house will use. I have to still keep the window from the end of the window to the 2.04 wall is 1.32M.

my suggestion includes keeping a bathtub and using a similar extended vanity counter to what you already have although the space underneath is better left open to make room for the longer bath with taps and hand held shower at the other end (great for kids baths) with the convenient seat

That looks great but no one in my family would use a tub. It would be better if i could have a larger alcove. Thanks heaps for the drawing btw!!

Really good plan, oklouise. Clever idea re additional storage.

Seems like a good idea oklouise!! probably won't do the glass all the way to the wall so I can have a slightly wider shower. Storage would be extremely useful!

Ended up getting the carpenter in to have a look at the storage cupboard and it seems like the cost of doing the storage unit will be more than the bathroom itself. Would be nice to have storage inside the bathroom for towels and candles etc..

always best to have all the facts from your local suppliers with which to make a decision but i have to say that you must be getting a great price for the bathroom, well done for you

I have tiny bathrooms so am always looking for ideas. I think that the cheapest and quickest way to make yours acceptable would be to put a second basin on the other end of the vanity and a narrow mirror or above each basin. Have you thought of placing a nib wall beside the bath, about 150cm high x70cm wide and 15 cm deep, where the glass screen is now and tile it with whatever tiles you choose for the floor. It takes away from cleaning glass screens or shower curtains for kids and it stops most of the water and looks good in the room. In your room it will also disguise where the existing tiles end. If you choose non glossy tiles for the floor and the wall, this is very easy to look after. Could you open the door the opposite way so that the first thing you see is not the toilet?

Is the wall to the left of the window wide enough for a shower? In that case I would line everything up on the wall with the window, anchored together with a full length skinny bench that extends into the shower as well. This would serve as shampoo shelf/vanity unit/toilet cistern concealment. The wall to the right of the window can have a large mirror cabinet up to the ceiling. You see this arrangement often in modern bathrooms, but the simplicity and clean lines of it can equally translate to more traditional interiors if that is your preference. Even if you made it totally modern the stained glass would not look out of place, as a homage to the age of the house.

Keep the toilet where it is for 2 reasons: difficult and expensive to relocate a toilet drain; also this location has a sidewall in perfect position for the paper holder.

I just had another look at your original plan. how much space is there between the open door and the 3.24m wall? it looks like about 300mm or more. If so, then you could have a long bench along that wall instead, with 2 basins and the shower at the end and leave the toilet where it is. that leaves the wall with the window free of other distractions, and allows you to have a mirror wall for the full length of that vanity, say 2.2m.

Window to the wall is 630mm. Storage is not a problem at all as I completely forgot about the linen cupboard right outside of my bathroom. Double Basins would be nice but I really would prefer to have a deeper shower.

Here is an idea, but it would work better if you rehang the door the other way, which shouldn't be too hard. The photo shows what I mean about continuing the shelf right along into the shower.

Completely get it now, so no cabinet under the sinks. Will definitely consider it but am worried if I will lose the traditional theme I'm going for. Highly appreciate your advice.

a traditional theme would have a bathtub so have the bathroom that suits you and your family and the long shelf with twin basins will give a very spacious feel to the bathroom, allow for mirrored wall cabinets for small storage and focus more attention on the stained glass window

Would a floating vanity suit your style? Or one that is more furniture-like? The images below are only to suggest vanity styles, not layout. I think something like these might work in your layout.

I think Daniel suggested that as space was the problem in my case.

Layout is now confirmed. Planning on not doing the tile the whole way to the ceiling outside of the shower. Would it look better if I continue it throughout up to 1M high or just put normal skirting ? (Price is not a factor)

I would put it shower height and then down to chair-rail height but with some sort of finishing like a smooth edge tile in the same style as the tile, or chair-rail or even aluminium or brass small edging which is not too obvious.

Thats what I was planning just can't find a single place in Australia that sells chair rail in marble or even porcelain.

instead of researching "chair rail" check out tile edging and/or tile trim and/or a solid piece of matching stone that can be cut into lengths to suit the purpose ...ask your tile suppliers for suitable products

Decided on carrara marble 300x600 tiles and honed nero and carrera for the shower floor. Floor to ceiling for the shower and up to the 1300 from the floor and painting the rest.

1. What colour fittings best suit carrara marble and keeps the transitional victorian theme?

2. The 3.24 wall has plasterboard over exposed brick. Do you think it would look nice if I took the plasterboard off and left that part exposed brick?

Any Response Appreciated!!

Going for something very similar to this.

I'm guessing the plasterboard on your 3.24 wall is moisture treated and appropriate for bathroom conditions. The brick will not be. Much as it might look good,I would not invite moisture issues into a newly renovated bathroom by exposing the brick.
