I would say this is to short. Your bath should be 150 mm from the wall + 75mm standard splash you are at 225mm. The water would land on the edge /rim of your bath. But do not fret. You could install free standing a timber shelf. Above bath for soaps etc and then have the spout mounted onto this? Or just get a new spout?

Hi, unless you take a bath at least once a week I'd skip the tub. I'd rather enjoy a bigger walk in shower, which is also a lot safer than climbing into a tub to shower. If you have the space instead of a tub and shower I'd consider a double vanity to give you extra storage space. It's a little luxury you will come to enjoy when everyone is getting ready on the morning.

Update... studied the temperature as I turned on hot water throughout the house

Hi oklouise The sad part is the existing bathroom is beautifully finished! This whole house was well finished and really well built. It was sad to have to demolish things that were so well done, but the design problems made changes necessary. The bathroom has porcelain wall tiles floor to ceiling on all walls and a white polished porcelain floor (slippery as all hell, and a mongrel to keep the grout lines clean!) is laid over a full 300mm+ of solid concrete, under which are all the drains. Outer walls are 200mm of reinforced solid concrete. Tiles on internal walls are over cypress timber frame with generally two layers of lining glued, screwed and nailed on - and there is way more timber in the frame than necessary. I think the builder (who built it for himself) thought the house would last forever and would never need to be changed in any way. Exact distance from external door to wall is 1.1m on both vanity and shower side. The door combination is 1200 wide and placed dead center. It's worth noting that 300m on the vanity side of the door is full-length frosted glass panel and it's possible to infringe a bit on that area if absolutely necessary, provided there's enough room for the door to swing safely (as it swings toward the vanity. I will take some photos now and share.
