Converting a closet or walk-in wardrobe into an ensuite bathroom is one of the smartest ways to add comfort, convenience and value to your home, especially if the master bedroom doesn’t currently have its own private bathroom.
Many homeowners assume they need a large space to install an en suite bathroom, but in reality, clever design choices and the right bathroom suites can transform even the smallest cupboard into a comfortable, stylish and fully equipped en suite. Whether you’re dreaming of a compact shower, a sleek wall-hung toilet, or a traditional Victorian plumbing style basin, the key to a successful project lies in understanding the space, choosing a layout that suits the room, and planning carefully from day one.
Turning a wardrobe or small room into an ensuite bathroom isn’t just a design trend — it’s a practical upgrade that improves daily life and enhances the feel of the entire bedroom. The convenience of stepping into a private bathroom first thing in the morning can completely change your routine, offering peace, privacy and ease. Many people with older properties find that bathrooms are often located on separate floors, which means adding an en suite creates much-needed comfort and a sense of luxury. Even smaller en-suites contribute to a more harmonious layout in the house and help create separation between shared bathrooms and private space.
Before you begin choosing tiles, colours, or a stylish pedestal basin, it’s essential to determine whether your existing closet or walk-in wardrobe can realistically become an ensuite bathroom. Look at the dimensions, ceiling height and layout of the room. If the space is extremely narrow, you may still be able to install a wall-hung basin and a slimline close-coupled toilet, as many modern suites are designed to suit tighter space constraints. You should also consider whether the space can accommodate waterproofing, ventilation and insulation. A smaller bathroom can be just as functional as a larger one if designed well, but you need enough space for movement and comfort.
Accurate measurements are essential when working with compact rooms. Many en suite bathrooms require only a few square metres, but the goal is to create something pleasant and practical, not cramped. Measure wall-to-wall distances, the depth of the room, and any corners or alcoves that may influence the layout. A space that appears small may still suit a corner shower enclosure or a compact suite designed for small bathrooms, while a deeper wardrobe might allow a more complete design with additional storage. Taking careful measurements also helps your installer plan plumbing, electrics and ventilation routes.
Plumbing is one of the biggest factors in determining whether a closet can become an ensuite bathroom. The toilet must connect to a soil pipe, and the closer your chosen room is to existing bathrooms or kitchens, the easier the installation typically becomes. If the new ensuite sits directly behind a bathroom wall, you may be able to piggyback off the existing waste route, which keeps costs down. Homes with older Victorian plumbing setups may require adaptations or upgrades to handle modern fixtures. A professional plumber can help you navigate these challenges and assess whether the project is feasible before committing financially.
Once you know plumbing is possible, you can begin designing the layout. In a smaller bathroom, layout is absolutely crucial for achieving comfort and flow. The most common options include placing the toilet, basin and shower along one wall to keep pipework simple, or using an L-shaped or corner layout when working with awkward or narrow spaces. Suites designed for compact rooms can help maximise depth and movement, and choosing wall-hung toilets or basins can add valuable floor space. Even a very small room can feel larger when the layout is planned thoughtfully from the start.
Bathroom suites come in a wide range of styles and sizes, and selecting the right one can transform the feel of your ensuite. Compact suites often include slimline toilets, narrow basins, and space-saving showers. If you’re aiming for a more traditional style, Victorian plumbing ranges often include elegant pedestal basins and classic taps that look beautiful even in smaller en-suites. Contemporary bathroom suites, on the other hand, typically feature sleek lines, soft-close seats, and minimalist finishes that help create a modern, luxurious feel. The key is choosing a suite that matches the space without overwhelming it.
Choosing the right toilet is one of the most important decisions you’ll make. A traditional close-coupled toilet is practical and familiar, but if you’re working with limited depth, a wall-hung toilet can be a fantastic option. Because the cistern is concealed within the wall, it creates a sleek, modern look and saves valuable floor space. Square and compact designs also work well in smaller bathrooms, as they fit more neatly into the available space. No matter which style you choose, make sure it complements both the function and the design of your ensuite.
The basin is used daily, so it must suit your needs without dominating the whole room. A pedestal basin works well when you have limited wall support, but a wall-hung basin is ideal for creating the illusion of more space. Some homeowners choose a compact vanity unit that combines a basin and storage, keeping everyday accessories neatly tucked away. With so many basins available — from round to square, from traditional to modern — you can easily find something that matches the overall style of your en suite bathroom suite.
Your shower choice has a significant impact on how the ensuite feels. Corner showers are a favourite for small bathrooms because they sit neatly out of the way, making the room feel more open. Square shower enclosures suit deeper wardrobes, offering a more complete showering experience without overwhelming the available space. If you prefer a luxurious feel, a walk-in or wet-room style shower with a frameless screen can bring elegance and contemporary style to your private bathroom. Just ensure your installer uses proper waterproofing to keep the room safe and functional.
One of the simplest ways to make a small ensuite bathroom feel larger is by using wall-hung fittings. These sleek, floating fixtures open up more floor space, giving the illusion of depth and openness. A wall-hung toilet paired with a matching basin can instantly modernise the room and contribute to a lighter, more spacious feel. Even accessories such as towel rails, toilet roll holders, and shelves can be wall-hung to keep the floor clear and create a more harmonious design throughout the space.
Storage can be difficult in small bathrooms, but with clever planning, you can create space for everything you need. Recessed shelves built into stud walls offer a smart way to store daily-use items without intruding into the room. Mirrored cabinets provide both storage and lighting benefits, making the ensuite feel brighter. You can even use narrow vertical cabinets or over-the-toilet shelving to create organisation without clutter. The key is to choose storage solutions that suit the room's scale while maintaining a practical design.
Because closets rarely have windows, creating proper ventilation is essential. Installing an extractor fan helps remove moisture, reduce condensation and prevent mould. For lighting, a layered approach works best: a mixture of ceiling lights, illuminated mirrors and soft accent lighting can help create a pleasant atmosphere. If you do have natural light in the space, take advantage of it by choosing lighter colours and reflective surfaces to brighten the room. A well-lit ensuite bathroom always feels more welcoming.
Colours play a huge role in how spacious and harmonious your ensuite feels. Soft neutrals, light greys, and warm whites create a pleasant sense of rest and peace, while darker shades add sophistication when used carefully. Textures such as stone, glossy tiles, or natural wood finishes can provide depth and elegance. To create cohesion with your bedroom, choose colours that match or complement the overall style and décor of the room. Even a small space can feel luxurious with the right finishing touches.
Flooring and wall materials must withstand moisture and daily use. Porcelain tiles, luxury vinyl boards, or waterproof wall panels are excellent choices for ensuring durability. If you prefer a more traditional look, patterned tiles add charm and character. Meanwhile, waterproof paint works well on non-wet areas of the wall. When selecting materials, think about how they will look alongside your chosen suite, taps and accessories to create a complete and cohesive design.
There are many ways to create the illusion of more space, even in a smaller en-suite. Large mirrors help reflect light and visually expand the room. Using large tiles rather than small ones can make the walls appear more continuous. Opting for clear shower screens instead of frosted ones helps maintain an open feel. Minimalist fixtures and sleek lines contribute to a sense of elegance and prevent the room from feeling cluttered. These design tricks help your ensuite feel brighter, bigger and more comfortable.
Heating a bathroom carved out of a wardrobe requires thoughtful planning. Underfloor heating is an excellent choice for small spaces because it eliminates the need for bulky radiators. If you prefer traditional heating, choose a slimline towel radiator that fits well against a narrow wall. Ensuring the room warms quickly is important for comfort, particularly on cold mornings, and contributes to the overall sense of luxury in your private bathroom.
The price of an ensuite conversion varies depending on plumbing complexity, finishes, and the bathroom suite you choose. Converting a closet can be more cost-effective than building a full extension because the structure already exists. However, you should budget for ventilation, waterproofing, and quality fixtures to ensure long-term durability. While the process can feel like a significant investment, adding an ensuite often increases the value of your property and enhances the appeal of the master bedroom.
While some people attempt small bathroom renovations themselves, converting a closet into an ensuite is usually best handled by professionals. Plumbers, electricians and bathroom fitters understand the technical requirements for safe installation and can help navigate building regulations. A professional can also help you choose bathroom suites, check structural integrity and design a layout that maximises the space. DIY can be tempting, but mistakes in waterproofing or plumbing can be costly, so expert guidance is invaluable.
A few common mistakes can reduce the quality of your ensuite bathroom. Avoid installing oversized fixtures that overwhelm the room. Do not skip waterproofing or ventilation, as this can lead to long-term damage. Make sure you plan your layout carefully so that the toilet, shower and basin feel comfortable to use. Consider how doors open, how accessories fit, and how storage will work in daily life. Taking the time to plan prevents frustration later and ensures a pleasant, practical result.
Bringing your design together is one of the most rewarding parts of the project. Whether you prefer a sleek, contemporary look or a more traditional style, the goal is to create a harmonious space that suits your bedroom and your lifestyle. Choosing quality taps, accessories, and finishes helps your ensuite feel complete and well thought out. With the right planning, even a smaller bathroom carved from a closet can feel elegant, practical and luxurious, adding daily comfort and enhancing your home for years to come.
Once the main layout and plumbing are sorted, this is the stage where you transform the space from simply functional to something that feels like your own personal oasis. Even in a small space, thoughtful finishing touches can make your new ensuite feel luxurious. For example, choosing a relaxing shower with a slim, short projection design helps maintain maximum layout flexibility while still giving you enough room to enjoy a proper wash after a busy day.
If you prefer something more traditional, you can add classic accessories or a Victorian-style basin to give the room elegance and character. Incorporating illuminated mirrors creates extra brightness, especially where natural light is limited, and they also double as practical features for daily routines. Adding clever storage around your vanity unit helps keep toiletries tidy, so there's no more fighting over the main bathroom each morning. Everything in your new ensuite should make daily life easier — from a stylish toilet that suits the décor to a basin or sink that feels comfortable for everyday use.
