I would have to say, it is not, a no no. However, how you decide to do this will determine whether it is positive or negative. If the toilet is in direct view as you enter it is likely to be negative, but the impact can be reduced with a smaller pan and an in-wall cistern. Noise and smell are often factors that will influence the decision. So, the smell can be overcome with an automated odor extraction system and there are also low noise inlet valves available. As far as property value is concerned there is a multitude of scenarios and just as many opinions, so consider how much convenience this will give you and how long you intend to stay in the property? perhaps it may be better enjoy your home the way you would like it to be.

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.

I do a thorough job weekly, but my partner has way higher standards of cleanliness and I do find him washing the sink and cleaning the shower doors on a daily basis. If he wants to do that, I don't complain about it. :)

As a suggestion, could put a free standing bath where the toilet is located. Then shower and toilet behind a wall with vanity in front... In the ensuite, put the vanity where the shower is and have a walk in shower. Howeer, you may need to relocate door.
