Just out of curiosity really. Growing up I don’t really remember them being much of a thing. Maybe large houses (4+ bedrooms) would have an en-suite off the master bedroom. I remember house hunting with my parents as a kid and a downstairs toilet was a deal breaker. Even then I don’t remember that many houses having en-suites/lots of bathrooms (I feel like we viewed hundreds of houses).
A few of my friends live in new builds and something I’ve noticed is a lot of bathrooms:bedroom/space. One friend has a five bed with five bathrooms! No wonder she has a cleaner…
My best friend has just bought his first house. It’s a cozy two bed, open plan downstairs with a WC, then the master bedroom with en suite and bedroom 2 (just about fit single bed + wardrobe) with the family bathroom opposite. He had been looking with his partner for months and just wanted something in budget, that had at least two bedrooms + parking.
It’s almost made me conscious that we’ve not future proofed with what we hope to be our family home. One family bathroom for three bedrooms (plus wc downstairs).
