When asked what he believed the secret to a happy marriage was, Hollywood actor Michael Caine once famously said it was having separate bathrooms. Now, while this might seem a bit on the extreme side for those of us who don’t live in a mansion in Beverly Hills, it’s worth bearing in mind that he’s been married for 46 years. And if you think about it, it makes perfect sense.

The bathroom is where we retreat from our hectic lives to have a bit of ‘me’ time, and relax and unwind. However, if you’re only blessed with one bathroom space for two people, what better way to ensure it’s a haven for both partners than by incorporating clearly defined individual zones into a design? So, where do you begin?

Every bathroom design should start with proper planning, and this is particularly true of a double bathroom. So, if you're installing something like a geberit aquaclean bidet - where in the bathroom should this be?

Find the focal point of the room and build your bathroom around it.

For example, simply placing two matching mirrors above a dual vanity unit will create a sense of balance that is familiar and pleasing to the eye, making the layout of the bathroom flow naturally.

It stands to reason that creating an equal balance in your special spa space between the two individual areas will make it easier to share it, and that in turn will have a positive effect. The goal has to be to create an intimate space where a couple can be both together and apart. Going back to Michael Caine, his other top tip for a happy marriage is  that he and his wife are ‘equal in everything’. Balance and harmony right there.
