Adding a second bathroom to your property can be a game-changer in terms of convenience, functionality, and overall home value. Whether it’s a compact downstairs cloakroom, a luxurious en-suite bathroom, or a family-sized addition with a full suite, homeowners are increasingly recognising the benefits of installing an extra bathroom. But how much value does it really add? And what should you consider before diving into the project?
This guide explores the practical, financial, and lifestyle advantages of adding a second bathroom, with expert advice on costs, layout, styles, and how to make the most of your available space.
Modern living has shifted the way we use our homes, and bathrooms are no exception. With more people working from home and growing families or shared accommodation on the rise, the need for additional bathrooms has never been more pressing. Waiting in line for a single bathroom each morning can be frustrating—adding another one solves that problem and increases your property’s desirability.
A second bathroom doesn’t always have to be large. It could be:
An en suite bathroom attached to the master bedroom
A compact cloakroom or WC on the ground floor
A full bathroom with a bath, shower enclosure, basin, and toilet
A smaller en-suite tucked into a loft conversion or guest room
Even a small bathroom with smart storage space and a modern layout can make a big difference to daily life.
Yes—en suite bathrooms are a major selling point, especially in larger or modern properties. They offer privacy, convenience, and a sense of luxury, particularly when connected to the master bedroom. A well-designed en suite bathroom enhances the value and appeal of your home, particularly when it includes desirable features such as a shower enclosure, illuminated mirrors, wall hung toilets, or a stylish toilet and basin combination.
Depending on your location and the property market, adding a second bathroom can increase your home’s value by up to 5–10%. For a property worth £300,000, that could mean a boost of £15,000–£30,000. That said, the final value depends on the quality of the suite, the layout, and how well the space is designed.
En suite bathrooms (also styled as ensuite bathrooms) have surged in popularity because they:
Provide a private bathroom space separate from the main family suite
Reduce traffic to the shared bathroom, especially during busy mornings
Create a personal oasis for the master bedroom
Suit the modern lifestyle of couples, professionals, and guests
From a practical standpoint, en suites reduce the stress of bathroom sharing and add a layer of convenience.
When designing your en suite or second bathroom, aim for features that combine practicality with modern appeal:
A space-saving vanity unit for basin and storage
A short projection or wall hung toilet to maximise floor space
Illuminated mirrors and smart lighting to enhance the overall feel
A well-tiled shower enclosure with sliding doors or walk-in access
These elements not only improve function but can boost value through stylish design.
Generally, you won’t need planning permission to install a second bathroom unless you’re making structural changes or adding an extension. However, you must comply with building regulations regarding plumbing, ventilation, and electrics. If you’re installing an en suite bathroom into a loft or garage conversion, it’s worth speaking to your local authority first.
Not every home has unlimited space. But with clever planning and compact suites, you can install an en suite in:
Underused areas of the master bedroom
Loft conversions or above-garage extensions
Spare rooms or walk-in wardrobes
Under the stairs or within an alcove
Look for compact fixtures like a corner basin, wall hung units, or short projection toilets to maximise limited space.
If you’re limited on floor space or working with a tighter budget, you may prefer a compact cloakroom-style addition. These typically include a toilet and pedestal basin, and they can still boost value by improving practicality.
On the other hand, if you have the room and budget, a full en suite bathroom suite with a bath or shower, toilet, and basin adds more luxury and impact—especially for future buyers.
Whether you're creating a small en suite or a full suite bathroom, style matters. A consistent colour scheme, thoughtful lighting, and quality finishes can turn even a small bathroom into a personal oasis.
Ideas include:
Soft colour palettes to make a smaller bathroom feel more spacious
Space-saving accessories like towel hooks or open shelving
Natural light and ventilation wherever possible
Linking your master bedroom to a private bathroom creates the feel of a boutique hotel. Many buyers now expect en suites as standard, especially in newly built homes. The more luxurious and practical the design, the more likely it will increase your home’s value.
The cost of adding a second bathroom or en suite varies depending on the type of suite, materials chosen, and complexity of the plumbing and layout.
Typical price ranges:
Small en suite: £4,000–£6,000
Full en suite bathroom: £6,000–£10,000
Larger bathroom or extensions: £10,000–£15,000+
Key factors that influence the final cost include:
Distance from existing plumbing and soil stacks
The type and quality of bathroom suites chosen
Whether structural changes are needed
Labour and installation fees
Flooring, tiling, lighting, and finishing touches
You don’t need to install a full bathtub or spend a fortune to create impact. Small en suites with sleek basins, stylish toilets, and a modern relaxing shower can still feel luxurious. Look for:
Compact corner shower enclosures
Wall hung furniture and mirrored cabinets
Subtle lighting and elegant accessories
Aside from property value, having a second bathroom brings everyday comfort:
No more fighting over bathroom time in the morning
Guests have their own space to freshen up
Better hygiene with less shared use
Easier household routines for families or shared homes
While an extra family bathroom might serve multiple users, bathrooms provide tailored privacy. The best choice depends on your household’s layout, how much floor space you have, and your long-term plans. Many homeowners now install both where possible for maximum flexibility.
To get the most value from your en suite, avoid:
Cramming in too much furniture for a small space
Poor ventilation or no extractor fan
Choosing cheap, low-quality fittings
Neglecting the overall flow between bedroom and en suite
If your en suite or compact second bathroom is on the smaller side, maximise storage space by:
Installing built-in or recessed shelves
Using vanity units with under-basin drawers
Opting for wall hung accessories like toilet roll holders and towel rails
Suite bathrooms come in a range of styles to match your home’s look. Popular options include:
Traditional Victorian plumbing fixtures
Modern wall hung vanity units and floating basins
Sleek minimalist designs with walk-in showers and monochrome finishes
Where possible, design your second bathroom to include a window or skylight. If natural light isn’t an option, use LED ceiling lighting, mirror lighting, and pale colour schemes to brighten the space.
Many bathrooms skip the bath due to size constraints, but if you have room and want a luxury feel, a compact bathtub can be an attractive feature. For smaller spaces, a spacious shower cubicle with stylish tiles and frameless glass will often be more practical.
Yes, in most cases. A second bathroom—whether a shared family suite or a private en suite—adds functional convenience, modern appeal, and resale value. It's one of the most desired features among buyers and renters alike.
Whether you're planning a simple cloakroom or a stylish ensuite bathroom connected to your master bedroom, investing in another bathroom can enhance your lifestyle and elevate your property.
A second bathroom is more than just a convenience—it can be the perfect solution in your home’s future. With careful planning, thoughtful layout choices, and quality finishes, your new suite bathroom can transform how you live and increase your home’s market value. Whether it’s a compact ensuite tucked into a corner or a fully equipped additional bathroom, the benefits are clear: added value, better flow, and a happier household.
