Smallest bathroom?

[ListersSister]

Looking for advice before we start to plan a downstairs bathroom....Does anyone have a small shower room/toilet that works well? If so, what size is it? What layout?

Has anyone got one that is too small, doesn't work? If so why?

I want to get a shower, loo and basin in the room. What is the realistic minimum size that needs? Are there any websites that can help plan?

Ta for any advice

Wet room set up may be the way to go? My friend has one and it is lovely.

Be a bit careful with a wet room though. Lovely but you need a decent company fitting it or you can have all sorts of problems

We had an ensuite which was about 5ft square and would n't go any smaller tbh. Some of the diy store sites like B and Q and suppliers like Ideal Standard have scale templates and do space saving ranges

bathroom planner - can't get it to load at the moment but have used it before, I worked out a shower room that was 1.5m square, smaller than that would be a problem I think

5ft square or so then? Hmm. It is likely the space we have is going to be a rectangle shape - long and thin, so I shall use that planner - thanks!
