We're building 4x3.5 Two with ensuite and the others with a jack and Jill. Life has changed unfortunately and now everyone in the household works, kids stay at home longer and ageing parents sometimes move in for care. At the moment we have a 3 x 1 and really the only thing we really want for is a second toilet, which growing up we had because we had the one out the back with the red backs.

Hi Evee, How about something like this? It would give you a very roomy bathroom, with everything you'd need. You could, alternatively, put the toilet where the towel rail is, and put the towel rail behind the shower door, which would give you space for a storage unit behind the bathroom door; but stepping out of the shower to face the loo might not be very attractive! Also, anyone walking into the bathroom won't immediately see anyone on the loo, as it's behind the door. I know there could be a fair bit of plumbing reorganisation, but I think that, no matter what you do, that will be the case. I think it would be worth the investment for a really functional and beautiful bathroom, though. Oh, and don't forget to put in a couple of double power outlets at the vanity - there always seems to be too few in most people's bathrooms. I hope this helps.And I agree with OKLouise about shopping around for bargains and second hand or re-purposed units. New things seem to cost the earth these days, but you save heaps this way, and you can use your money for plumbing and electrical. Good luck! Would love to see a picture of the finished product.

@HU-319610855 I’m not saying this to be even the slightest bit contradictory, so please don’t take it that way. We had seperate everything. Doors, walls and divisions everywhere. We pulled it all out and went combo. We‘ve never had an issue with conflicting use, and we love the feeling of extra space and openness it created. I’m sure it all depends on your household. :-)

I would prefer to keep the WC separate to the Bathroom as you have 3-4 kids? who will get bigger very quickly, having a powder room downstairs won't help with the morning rush to school., But it's your house so I have added a pocket door between the WC and Bathroom. I have also taken that small robe space for an extra vanity in the WC/Powder room. No width dimesion given for the WC The ensuite could use that extra entrance space as a sit down makeup and hair bench for your wife.
