I live in the country and am completely reliant on tank water. I also have a grey water recycling system and can tell how much water has gone through it at any one time as the filters need to be cleaned after so many litres of water go through them. I can almost guarantee that the bath with a couple of grand kids splashing about for twenty minutes having fun will use less water than any of their parents showering does. Even topping it up with more hot water if needed. Unless you are very conservative with your showers baths are not that bad and the value they add to the resale of the average home outweighs any downside. I definately wouldn't buy a house without one. I have had a house that has a bath the size of the shower though, about 1m x 1m by maybe 40cm deep and I think it was called a hip bath. My sister in law has one at her house, she got it from Lanark, as her house only had a shower which is not practical and it was the cheaper option than redoing the whole bathroom. I dont know if that is what you are after or not.

This explanation may help, Source: https://www.renovatorstore.com.au/blog/lighting-and-power-in-your-bathroom-the-simple-rules-to-be-safe/ REQUIREMENTS Zone 0: Inside the bath or shower. Any Lighting used here must have a minimum rating of IP67 (protected against immersion in water) Zone 1: Above the bath or shower to a height of 2.25m. A minimum rating of IP44 is required Zone 2: The area stretching to 0.6m outside the bath or shower and above the bath or shower if over 2.25m. An IP rating of at least IP44 is required Outside Zone: Anywhere outside zones 0, 1 & 2. Where water jets are not to be used for cleaning purposes, the general rules of BS7671 apply In addition to the above, if there is a likelihood of water jets being used for cleaning purpose in zones 1 and 2 a fitting rated a minimum IP65 must be used. Now that this has been explained, always make sure to purchase bathroom lighting according to these standards to make sure that your bathroom is always safe. You should also have this principle applied when you purchase other electrical devices such as heated towel rails, or a guide to where you'd put sockets in your bath for razors and other devices. This may also fix the common misconception that LED lights are not rated for bathrooms. Typical LED lights have an IP rating of IP66 which is more than the needed IP rating standard that bathrooms should have. - Not to mention you'd be saving a whole lot from energy bills in the long run.

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.

I had a other look at this post because the subject of a laundry trough often comes up. They are required but the construction you’re putting in will meet the requirements. Below are some handy references. The video (presenter isn’t going to win a Grammy) is quite good.
