1. Unite the decor in a Jack and Jill bathroom

When spaces are within the same line of sight, it’s important to make connections using materials, colors and finishes. In this bedroom, the open-plan Jack and Jill bathroom was designed in tandem, and the results are beautifully cohesive. Architects Humbert & Poyet inlaid timber panelling and mirrors with brass and added brass hardware and taps to help everything flow as one.

2. Make an entrance

Regardless of your Jack and Jill’s dimensions, switching inward opening doors for sliding or pocket versions, or no door at all, will ensure every inch of the interior is usable. Install double doors to improve the flow and allow ‘borrowed light’ from the bathroom to brighten up the adjoining bedrooms. As privacy is less of an issue, the doors can be left wide open most of the time.

3. Boost the space

Even when space is tight it’s possible to create a spacious feeling Jack and Jill bathroom. 

‘This luxury bathroom idea optimizes every inch by combining the bath and shower, and the cleverly designed double basin has surprisingly small dimensions and ample storage underneath,’ says Clara Ewart, head of design, Kitesgrove. ‘Quality marble bathroom ideas with interesting veining always sets a luxurious tone; we kept the overall scheme light and pared back to make it feel airy.’

4. Add a luxe bath

If space allows, a luxurious tub will secure your Jack and Jill’s sanctuary status. ‘The bathtub is perhaps the one space in a home without interruption from the outside world, so we always recommend making it as indulgent as possible,’ says Louise Lythe, associate director, David Collins Studio. ‘Facing the bath to enjoy views outside can enhance that sense of drifting off, creating time to fully recharge.’

5. Hide it away

‘Having a separate WC built into a Jack and Jill bathroom is the ultimate in luxury. While relaxing in the tub, it’s nice not to have a toilet in your eye line, even nicer not to witness it being used,’ says Georgina Fraser, design director, Jeffreys Interiors. 

In this Jack and Jill bathroom, slim double doors create privacy without obstructing light from the main windows. When the doors are closed, the cabinetry resembles a closet.

6. Combine your Jack and Jill bathroom with your dressing area

Combining your dressing room and Jack and Jill bathroom can result in a more generous layout. 

‘This open-plan design makes the bathroom feel like an extension of the bedroom, and the richer materials and textures are more inviting and intimate,’ says Pierce Coyne, designer, Kitchen Architecture. ‘Consider the higher moisture levels when choosing wardrobe finishes.’

7. Install a double vanity

Designed as a shared space in which to wash and clean your teeth, a washstand for two has become a must-have in a family bathroom. Whether planned as part of a renovation or on the wish-list when buying a new house, double basins – especially in Jack and Jill bathrooms and en suites – are a neat style statement

The advantage is clear: the ability for two people to have access to a sink at the same time takes enormous pressure off the main bathroom, especially in a chaotic family home. 

8. Invest in built-in storage 

Clever bathroom storage ideas are essential to making a Jack and Jill bathroom work. It has many demands put upon it, not only to be a practical, user-friendly room but also as a tranquil place to start your morning routine. 

Shared or limited space can create a challenge when it comes to making the best of any Jack and Jill bathroom. However, the items that need storage, like bulky towels and numerous toiletries, can also add to the decorative look of the bathroom, so it's worth thinking about how you can show them off to their best advantage. Even though a Jack and Jill bathroom is often considered a purely practical space, that doesn't mean it can't be stylish as well.
 

9. Lay down non-slip flooring in a Jack and Jill

Non-slip bathroom flooring deserves special attention in a Jack and Jill bathroom. The material of course must be highly durable, able to withstand frequent splashes of water, anti-slip underfoot and easy to clean, especially when used by children.

Vinyl doesn’t always get the best rep when it comes to luxury bathroom design, but the material has myriad benefits, many of which make it a great choice for a Jack and Jill bathroom. This material is improving in quality with new technologies and also offers a wide range of design opportunities that will suit a variety of modern bathroom ideas. 

10. Ensure you have a good lighting setup

When it comes to the best Jack and Jill bathrooms, efficient bathroom lighting ideas are an integral design element that should be planned at the start of a project.

Task lighting is generally concentrated around the vanity. Here, you need bright light for completing tasks, but think about installing spots or LEDS in vertical rows down the side of mirrors as opposed to above, to give a more flattering light with less shadows. In small Jack and Jill bathrooms, look at mirrored cabinets with internal lighting as a simple but effective solution.

Place your lights on dimmers and separate circuits, says Sally Storey of John Cullen Lighting. 'This will allow you to switch between bright light needed for cleaning and softer levels for a more tranquil atmosphere.'
