Feeling cramped in your small bathroom?

Are you standing in your bathroom wondering how on earth you'll ever make it feel less cramped? Is your current bathroom layout wasting precious space that could be better utilised? Are you worried that your compact bathroom will never feel spacious, no matter what you do?

I completely understand. When it comes to bathroom renovations, space is often the most significant challenge our clients face. 

The good thing is, with some clever design tricks and innovative solutions, even the smallest bathrooms can be transformed into functional, spacious-feeling rooms that you'll love using every day.

In this article, I'll share the best space-maximising techniques I've developed over 15+ years of bathroom installations across Staffordshire. I'll cover everything from layout optimisation to clever storage solutions, and show you how to make your bathroom feel twice as big – even without knocking down walls (though sometimes that's an option too!).

Looking beyond what's visible: Finding hidden space

One of the things I get really excited about when visiting clients' homes is spotting opportunities they didn't even know existed. You'd be amazed at how much untapped space is hiding in many bathrooms.

Reconsider your layout

The first thing we always look at is whether the current layout makes the best use of the available space. Sometimes the solution is obvious once someone points it out.

We had a client in Stafford with a tiny bathroom that had been the same layout for 20 years. The bath was taking up one entire wall, and everything felt cramped. When we visited, I immediately noticed that by rotating the bath 90 degrees and slightly reconfiguring the plumbing, we could free up nearly a metre of floor space. They couldn't believe the difference such a simple change made!

Sometimes it's not just about moving things around but questioning whether you need certain elements at all. For example, if you rarely use your bath, switching to a walk-in shower could free up significant space. Or perhaps that bulky vanity unit could be replaced with a sleek wall-hung basin.

Look for hidden opportunities

Here's where my experience really comes into play. I've often found space in places homeowners never thought to look:

Stud walls often conceal unused space that can be converted into recessed storage niches. These are brilliant for shower toiletries or decorative items.

The space above the door is frequently unused but can accommodate a slim storage cabinet.

That awkward corner might be perfect for a custom-built storage solution.

I remember working on a bathroom in Newcastle where the client thought they'd need to extend to get the space they wanted. After inspecting the property, I noticed their bathroom had a false wall hiding old pipework that was no longer needed. By removing it, we gained an extra 30cm across the entire room – enough space to install the walk-in shower they thought was impossible!

Smart storage solutions that don't compromise on style

Storage is crucial in small bathrooms. But it's not just about having enough places to put things – it's about designing storage that doesn't make the room feel cramped.

Wall-hung fixtures create visual space

One of my favourite space-saving techniques is to get things off the floor. Wall-hung toilets, basins and vanity units make a massive difference to how spacious a bathroom feels. When you can see more of the floor, the room instantly appears larger.

The technical bit is that we hide all the brackets and cisterns within the wall, so you don't lose any functional space. Plus, it makes cleaning much easier since there are fewer nooks where dust can gather.

Built-in storage beats freestanding furniture

Built-in storage that utilises otherwise dead space is worth its weight in gold. Here are some approaches we often recommend:

Recessed shower niches eliminate the need for shower caddies or corner shelves, keeping your shower area clean and spacious. We always suggest including at least one of these in any shower design.

Floor-to-ceiling tall units in otherwise unused corners can provide substantial storage without eating into the room's footprint.

Storage built into partition walls serves a dual purpose – dividing the space while providing handy storage.

We recently completed a project in Stone where we built a half-height wall with storage niches facing the bath, and a tiled shelf on the other side for the basin area. The client told me it's transformed their morning routine because everything they need is right at hand without cluttering the surfaces.

Think vertically

Many bathrooms have untapped vertical space. Tall, slim cabinets can provide surprisingly generous storage without taking up much floor area. Similarly, towel rails stacked vertically rather than horizontally can save wall space.

"I always tell my clients that in a small bathroom, the walls are your friends," says Craig from CSI Bathrooms. "Using vertical space efficiently means you don't have to compromise on storage even in the smallest rooms."

Create the illusion of space with clever design tricks

Sometimes physical space is limited no matter what layout changes you make. That's when visual tricks come into play – making the bathroom feel bigger even if it isn't.

Strategic use of mirrors

Mirrors are powerful tools for creating the impression of space:

A large mirror across one wall can visually double the size of your bathroom. For extra impact, position it to reflect a window or light source.

Mirrored cabinet doors serve the dual purpose of storage and space enhancement.

Consider unusual mirror placements – even a partial mirror above eye level can create the feeling of height and space.

Lighting makes all the difference

Poor lighting can make even a decent-sized bathroom feel cramped and unwelcoming. I'm passionate about getting bathroom lighting right:

Layered lighting that combines ambient, task, and accent lighting creates depth and dimension.

LED strips beneath wall-hung furniture create a floating effect and make the floor space appear larger.

Motion sensors that activate softer lighting when you enter the bathroom at night have become really popular with our clients. They give that luxury hotel feel and eliminate the harsh brightness of switching on the main lights.

One bathroom we completed in Stafford incorporated LED lighting behind the bath panel. It created this beautiful warm glow across the floor that made the room feel twice as big at night – plus it's perfect for those relaxing evening soaks!

Colour and tiles play a part

While we're primarily focused on physical space, your choice of colours and materials has a massive impact on how spacious the bathroom feels:

Lighter colours generally make spaces feel larger, but that doesn't mean you're restricted to white. Soft neutrals and pastel tones work beautifully too.

Using the same tiles on the floor and walls creates continuity that expands the space visually.

Large-format tiles mean fewer grout lines, creating a cleaner, more spacious look.

Wet rooms and walk-in showers: Space-efficient alternatives

If you're willing to make more substantial changes, converting to a wet room or walk-in shower can dramatically transform a small bathroom.

The benefits of wet rooms for small spaces

Wet rooms eliminate the need for a bulky shower enclosure, instantly making the bathroom feel more open. With the right tanking (waterproofing) and drainage, your entire bathroom floor becomes the shower area.

The practical benefits are significant too:

Improved accessibility for all ages and abilities Easier cleaning with fewer nooks and crannies No shower tray to step over A contemporary, luxury feel

We created a wet room for a client in Hanley who had a bathroom measuring just 2m by 1.6m. By removing the separate shower enclosure and installing a simple glass screen, the bathroom suddenly felt spacious rather than cramped. They said it was like having a bathroom from a boutique hotel!

Walk-in showers as a compromise

If a full wet room isn't practical or within budget, walk-in showers offer many of the same benefits. With a low-profile shower tray and frameless glass screen, they create a sense of openness while containing water more effectively than some wet rooms.

The real beauty of walk-in showers is their flexibility. We can customise them to fit unusual spaces or awkward corners, making them perfect for maximising space in quirky bathrooms.

Consider removing internal walls or borrowing space

Sometimes, the most effective way to maximise bathroom space is to change the room's footprint entirely.

Combining rooms for better functionality

In older properties, it's common to find a separate toilet and bathroom. Combining these spaces often creates a much more practical, spacious room.

I recently worked on a project in Stoke where we removed the wall between the toilet and bathroom, creating one larger room. The difference was remarkable – not just in terms of floor space, but in how much more functional the room became. The clients went from having a cramped bathroom and a tiny toilet to having a spacious bathroom with plenty of storage and a comfortable amount of space around each fixture.

Stealing space from adjacent rooms

If you're undertaking a larger renovation, consider whether you could borrow space from an adjacent room. Sometimes, taking just 30cm from a neighbouring bedroom can make the difference between a cramped bathroom and a comfortable one.

Of course, this approach requires more significant work, but if you're already planning a renovation, it's worth exploring. I always recommend having a structural engineer check whether walls are load-bearing before making any major changes.

Choosing space-efficient fixtures and fittings

The fixtures and fittings you choose can have a huge impact on how spacious your bathroom feels and functions.

Space-saving toilets and basins

Modern bathroom fixtures are often designed with space-saving in mind:

• Wall-hung toilets take up less physical and visual space.

• Corner toilets and basins utilise otherwise wasted areas.

• Combination units with integrated basin and toilet systems save space in ultra-compact bathrooms

Shower design considerations

In small bathrooms, shower design requires particular attention:

• Frameless shower screens create a more open feel than framed ones.

• Sliding doors require no clearance space, unlike hinged doors. 

• Ceiling-mounted rainfall showers eliminate the need for protruding shower arms.

Baths for small spaces

If you're determined to keep a bath in a small bathroom, consider:

• Back-to-wall baths that fit flush against the wall.

• Shorter baths, some are as little as 1500mm long.

• Shower-bath combinations that serve dual purposes.

I remember a client in Stafford who was adamant they wanted to keep their bath, even though their bathroom was tiny. We found a compact bath that was 20cm shorter than standard, and designed a custom storage solution at the end to make use of that otherwise awkward space. They got to keep their bath without compromising on the rest of the bathroom's functionality.

Real-life transformations: Small space success stories

Some of my most satisfying projects have been transforming small, awkward bathrooms into spaces that feel generous and luxurious.

There was a family in Stone who had a bathroom under the stairs – an incredibly challenging triangular space that previous installers had refused to take on. By designing a custom walk-in shower that utilised the tallest part of the room, and installing a compact wall-hung toilet and basin in the lower sections, we created a fully functional bathroom that felt surprisingly spacious.

Another memorable project was for an elderly couple in Stafford who needed an accessible bathroom but were worried it would look "clinical" and cramped. We designed a wet room with discreet grab rails, a wall-hung toilet, and plenty of clever storage. The result was a bathroom that met all their accessibility needs while feeling spacious and stylish.

What I've learned from these projects is that with creative thinking and the right expertise, even the most challenging spaces can be transformed into beautiful, practical bathrooms.

Planning your space-maximising bathroom renovation

If you're planning a bathroom renovation with space maximisation in mind, here are some practical steps to take:

Start with an honest assessment

Be realistic about what you actually need in your bathroom. A massive rainforest shower might be your dream, but if it means sacrificing all your storage space, it might not be the best choice.

Make a list of your must-haves versus nice-to-haves. This helps prioritise what's essential when space is tight.

Consider professional design input early

One thing I've noticed over the years is that clients who involve us early in the planning process often end up with much better solutions. That's because we can spot opportunities and potential issues before any work begins.

I can't count the number of times I've visited homes where people have already purchased fixtures that simply won't work well in their space. Getting expert advice before you buy anything can save both money and disappointment.

Don't forget the practical details

When maximising space, remember the practical aspects:

Building regulations require certain clearances around fixtures Door swing directions can significantly impact usable space Storage needs often expand over time, so plan for slightly more than you think you need

Frequently Asked Questions

What's the minimum size needed for a wet room? There's no absolute minimum size for a wet room, but practically speaking, you need enough space for comfortable movement and effective drainage. Even bathrooms as small as 1.5m x 1.5m can be converted to wet rooms with proper planning.

Will removing my bath decrease my home's value? This depends on your property and local market. In homes with multiple bathrooms, converting one bath to a shower rarely affects value. However, if you only have one bathroom, retaining a bath might be advisable for resale purposes.

How much storage do I really need in a bathroom? This varies by household, but most people underestimate their storage needs. I recommend listing everything you need to store, then adding 20% for future items. Remember that well-designed storage can actually make a bathroom feel less cluttered and more spacious.

Can moving plumbing positions help maximise space? Absolutely. While it involves additional cost, relocating plumbing can sometimes transform an awkward layout into a highly efficient one. Modern plumbing solutions offer more flexibility than many people realise.

Are there specific tile sizes that make a bathroom look bigger? Generally, larger format tiles with minimal grout lines create a more spacious feel. Consider tiles in the 30x60cm to 60x60cm range for smaller bathrooms. Using the same tiles on both floors and walls can also enhance the sense of space.
