With its L-shaped design, this corner Jack and Jill bathroom allows for a central corridor between two bedrooms, with a private water closet and shower room.

Dimensions: Varies (Typically 8’ x 10’ / 2.4m x 3m)

Design Tips:

• Add built-in shelving or linen storage in one corner for organization.
• Use pocket doors leading to the bedrooms for accessibility.
• If there’s space consider built-in storage niches or a closet along the open wall near bedroom 1 entry.
• Use a corner shower design to maximize interior space.

Shared Bathroom Design Tips

When it comes to optimizing your Jack and Jill bathroom layouts there are some design tips that can help you get the most out of your floor plan. One of the easiest ways to create more room is by replacing your swinging doors that take up a lot of space with sliding or pocket doors. After that take a look at using corner shower enclosures or tubs when possible as they otherwise require additional clearances around them.

Using wall-mounted toilets and faucets is another way to minimize the fixture’s footprint to save a little space. When it comes to toilets you can consider using compact models with round, over elongated seats to save some room.  

Using storage solutions such as recessed medicine cabinets, built-in wall niches and over the toilet shelf towers are other space-saving options that can help. If possible consider adding built-in shelving inside walls for towels and bathing products. Add multiple towel hooks near the tub or shower for each person to have their own hanging up. Organize the areas inside your vanity so guests can easily find the essentials they need.

There are also ways to visually increase the appearance of a room with some cosmetic adjustments such as using a lighter color palette and installing plenty of lighting fixtures and allowing windows with window treatments that enhance natural light.  Using larger mirrors can also reflect light and help brighter the overall look. 

At the end of the day, it important to think about how the shared space bathroom will be used. If you have a smaller room consider a shower tub combination that can eliminate wasted space. Plan for multiple users by considering proper zone layout so each person has their own areas for grooming and storing their essential items.
