We have a very large family bathroom. It has a bath and a separate shower.
Then we also have a tiny en-suite. This has a shower.
Both showers are on a pump so powerful.
The bedroom with en-suite is actually used as a guest room/office. Therefore most of time that shower is not used.
This works well for us as a small household of 3 at the moment. The big family bathroom is fine for the 3 of us. We don’t experience queues and if we did someone can nip to the en-suite. Plus, when guests stay they get their own bathroom and don’t have to use ours.
If we were a larger family of 4+ the en-suite would probably be in use and we’d be in that room.
Guests would then end up using the family bathroom with the children. That would be fine as occasional use.
En-suites work well for those who like the privacy, aren’t bothered about loo in bedroom thing, and also for smaller households, where ther aren’t too many others to use the family bathroom, esp if there are just 2 loos in the house.
2 separate bathrooms (neither en-suite) become better the larger the household.
I agree that most people these days are looking for 2 Bath/shower rooms in a 3 bed plus and certainly in a 4 bed+. If this can’t be had, 2 loos are expected by most these days and even smaller houses have often crammed an extra one in. En-suite can often be crammed in more easily, and often it’s a needs-must for space.
New builds with 2 shower/bathrooms always have one that is en-suite. This is probably partly due to space issues but also a reflection of demand, it is what most people want. New builds always have a downstairs loo too, so visitors can use that and family bathroom/en-suite not accessed by visitors unless over-nighters. I know lots have a horror of visitors in their bathroom.
Don’t forget the vast amount of 3 bed older housing stock with just 1 loo/bathroom which can’t have an extra loo or bathroom. Families continue to manage fine, but where it’s possible, people squeeze at least a loo in. Expectations rise over time.
