We have removed the water tank now. The measurements are 2.1mx2.3m x

Hi, I’ve noticed in your ideabook pictures of walk in showers - is this what you’re after without a bath, or do you want a shower over a bath? Also, is the window wall 2.3m or 2.1? Presuming the room is now almost square?

Hi, I would prefer a bath really, a shower wou be a bonus but I don't know how it would fit without looking out of place. The room is almost square and the window wall is 2.3.

I think is most likely way to have both bath and shower. You can have a walk in shower which is open to the bath side. Think wet room, the bath will get wet when you shower. But this sort.of layout will look the most open with just a glass panel up near the door.
Even if you skip the separate shower I'd swap the direction of the bath, slide up the WC (so it's not the first thing you see) and pop the basin where the WC is currently located.

I was looking at the first picture, wondering what that little pipe was, sticking out of the bath...

I think I know now... Haha

I think a showerbath would be the best option. Carron do some good bath designs and I'll likely use Victoria Plum online for my sink vanity units.

Here is an example of the bath open to the shower layout.

Yes, that looks nice, I'll suggest this to him. So the shower and bath would be on the righ hand side as you walk in to the room?

What do you think the best design is without a seperate shower?
