Planning a bathroom will take perhaps more thought than any other room – the kitchen might be the exception but, even here, there is invariably the reassuring presence of a kitchen designer to smooth the process.
With the bathroom, you will often find yourself managing the plasterer, the plumber and the flooring installer alone.
The typical bathroom is small, requiring clever use of space to shoehorn in all the desired features and make it good looking and comfortable at the same time.
And installation can be deceptively tricky, involving plumbing, intricate spatial design and technical skill, so it pays to have some kind of design service, either from an interior designer, a specialist bathroom designer or, at the very least, an experienced builder/plumber with an eye for design.

How to plan a bathroom
Much like planning a kitchen, you can get the ball rolling by analyzing how you use your current room, noting what works and what doesn’t, then drawing up a wish list that takes into account all potential users, their individual needs and imagining how these might change in the future.
For instance a family bathroom will usually require a bath, hardwearing and splash proof surfaces while an en suite can afford to be a bit more luxe.
What is a good bathroom layout?
A good bathroom layout will depend on many factors, such as, the function of the bathroom, the size, who will be using the bathroom, and how often. Let's start with the design effects a good bathroom layout can create:
- The view upon entrance is an important part of design so makes a good starting point for your bathroom layout – you want to see the bath or basin first, not the toilet.
- Choose one key piece, be it a freestanding bath, heart-stopping vanity unit or a beautifully tiled shower area and build the layout around it.
- Symmetrical layouts: if the room’s proportions lend themselves to symmetry, it is worth plotting a symmetrical layout, perhaps aligned with an architectural gem like an original sash window.
- Make space: ensure there is adequate space around each fitting for comfortable use and pay attention to the swing of shower doors; in a tight space choose inward opening doors or an over-bath shower.
- Ask experts: ‘Seek specialists' help to see beyond the existing layout. It’s surprising how even the smallest of bathrooms can be imaginatively planned,’ adds Darren Paxford, National Sales Manager, Vitra.
- Create drama in larger bathrooms: avoid everything clinging to the walls and instead experiment with angles – an offset bath can prove more dynamic – or bring the bath forward and create a walk-through shower behind.
'When planning a bathroom, always start with the layout,' advises Yousef Mansuri, Head of Design at C.P. Hart. 'This layout of the scheme is primarily dictated by the position of the soil stack pipe for the WC and whether it can be moved or not. The toilet has stricter limitations than moving pipework due to the fall of the waste.'
The ideal is to work with minimal bends in the toilet's pipework to avoid blockages, so relocation can require significant effort, but is not impossible. The job is easier if the new location follows the direction of the floor joists. It is also possible to move a toilet further along the external wall that hosts the soil stack, drilling a new hole through the wall and connecting into the soil stack externally.
'Once you know where this is positioned, you can start thinking about where the basin, bath and shower will go. Pipework tends to be more flexible when it comes to repositioning,' continues Yousef.
Another option is to install a new raised floor, with enough depth for pipes below but this will result in a step in the room. 'Once you have your layout and therefore measurements, the exciting part starts – you can create your mood boards and choose your products. Make sure you don’t forget about towel rails and heating when considering all of this. One big mistake we often see is once having left the shower, people have to walk across the bathroom to reach their towel.'
How to plan a family bathroom
This is usually the biggest bathroom in the house, accessible from the main hallway. Fittings and finishes in a busy family bathroom should be selected with low maintenance and durability in mind.
‘I would always use porcelain tiles in a family bathroom, including slip-resistant porcelain on the floors, as they are very hard wearing and will still look amazing in years to come,’ says Ripples’ senior designer Katie Gisby.
‘They also require zero maintenance, which is essential.’ Plenty of storage is also essential, for toys for toddlers to an ever-growing range of toiletries in the teens.
Double up on vanity units, basins and mirrors where space allows and don’t be tempted to evict the bath if it is the only one in the house. Instead consider a space-saving shower-bath.
How to plan a master en suite
In a master en suite, only used by responsible adults, you can afford to throw caution to the wind and splash out on luxurious materials and a more complex lighting scheme to create a relaxing mood.
If there’s space, opt for his and her vanity areas with attached dressing rooms if you’re very lucky. This is the place to splash out on expensive equipment like a steam shower or elaborate sound system, which might get damaged by tampering tots or clueless guests, and to indulge in luxe surfaces to your individual style.
If space is tricky, consider a bathtub in the bedroom with just a small area sectioned off for the toilet and basin.

Planning shower rooms, wet rooms and guest en suites
Shower rooms and guest en suites can often be squeezed into a surprisingly small footprint using space-saving fittings and a cloakroom basin. Keep it simple, safe with thermostatic valve showers and easy to clean.
'The first thing to consider with a shower is the type of floor you have. Be it a tray or tiled floor, an anti-slip option is essential,' advises Yousef Mansuri of C.P. Hart. 'Many steel trays offer an anti-slip option and composite trays are often matte in finish for additional grip. If tiling the shower floor, it’s incredibly important to choose a matte finish tile for grip, rather than a gloss, which would be dangerous.
'If opting for a wet room, there are several designs available, from ultra-minimal frameless options to the bold statement black Crittall styles. It’s important to note, that if the width of the panel is larger than 1100mm, you will require a bracing bar for stability.
'These can either be fixed to the wall or the ceiling, depending on the design. Some homeowners, however, prefer an entirely enclosed shower rather than a walk-in. The benefit of this is that the heat is kept within the showering space.'

Pick the perfect bath
'Baths come in many different shapes, styles and materials, and consequently there are baths for every budget, style and need,' continues Yousef Mansuri. 'Freestanding stone, composite and cast-iron baths are at the high end of the price spectrum and offer substantial benefits compared to inset steel and acrylic tubs. Composites are warm to the touch and can be repaired easily, while cast iron baths arguably have the best heat retention properties.'
Find the best brassware
'Brassware is one of the the most important elements of any bathroom. As working parts with continuous water flowing through them, they need to be durable enough to withstand the wear and tear of daily use,' says Youssef Mansuri.
'Of all the elements that make up a bathroom, we recommend investing in quality brassware to ensure longevity. Most brassware is wall mounted which makes it much harder to fix. Therefore, paying more for brassware at the beginning will pay dividends later on.
'It’s also important to pick products that suit a property’s water pressure. Older Victorian properties for example, typically do not have suitable plumbing to give enough pressure for large overhead showers.'
Prioritize bathroom lighting at planning stage
Lighting can have a massive impact on the end result and should be planned at an early stage to ensure all key fittings are illuminated properly.
'Bathroom lighting is as important as positioning the sanitaryware,' says Yousef Mansuri. 'The overall mood and atmosphere of the bathroom is dictated by the lighting scheme, so this should be decided prior to signing off any designs. Make sure you consider lighting without relying too heavily on downlights.
'Although these are fantastic at giving an even covering of light, they are not the most sympathetic and can often take the charm out of a room, leaving it looking clinical.
'Try using two lighting circuits, one for the downlights and another which includes more inventive feature lighting, such as recess lights, under basin lights, wall lights and marker lights fitted to the floor to up light the bath.'
Aim for sufficient task lighting in the shower and vanity areas, plus ambient lighting around the bath and in alcoves and niches. The latest smart lighting controls allow pre-programmed settings.
‘These lighting scenes cover everything from early morning with lights gradually illuminating to a daytime level, to an evening scene that is dimmed to create a peaceful ambience to relax and unwind in,’ explains Phillip Pini, Residential Business Development Manager at Crestron.
Look out for wireless lighting controls, such as Crestron’s Pyng™ system, which is installed without cables and can include control of thermostats, security and audio, if desired.
What else do I need to consider when planning a bathroom?
Shiny new fittings can highlight imperfections in the original space so it's worth updating architectural elements like doors, plinths and cornicing. A simple skim of plaster can tidy up a scrappy ceiling. Well-dressed windows will also help create a really smart finish. Plantation shutters designed for bathroom use will provide privacy and are easy to clean.
Don’t forget to keep some budget back for beautiful accessories that will bring the whole look together. ‘Take your lead from boutique hotels and make sure there are plenty of lovely toiletries and squishy thick towels,’ adds Alternative Bathrooms’ director Jane Gilchriest.
Will an extra bathroom add value to your home?
Adding extra bathrooms is a recognised way to boost your property’s value and can do wonders for the morning rush hour.
Options include turning an adjacent box room into an en suite, stealing an unused area of an upstairs landing or using stud walls to section off a large bedroom.
If there are no options upstairs, consider expanding a downstairs cloakroom or utility into a shower room.
The advent of electric showers and pumped drainage systems, such as macerators, means there are few spaces that can’t accommodate bathroom fittings.
Macerators are noisier than gravity-based drainage, but many people can accept the compromise, particularly if the extra bathroom is only intended for occasional guest use.
Plumbing a new room is easier and cheaper if it is located next door to an existing bathroom or above the kitchen, and not too far from the external soil stack, so that pipework doesn’t have far to travel.
