What Is Included in a Full Bathroom Design Service? A Step-by-Step Breakdown

A well-designed bathroom is about more than what looks good.

The layout needs to work. The products need to fit. The finishes need to sit comfortably together. The plumbing, lighting, storage and practical details all need to be resolved before anything is installed.

That is where a good bathroom design service makes a difference.

At Kallums Bathrooms, our bespoke bathroom design service takes you from the first conversation through to a finished, fully specified bathroom, with our design teams based in our Putney showroom and Guildford showroom.

So, what does a full bathroom design service actually include?

What is a bathroom design service?

A bathroom design service is a way of planning the whole room before you commit to products or installation.

Rather than choosing a basin from one showroom, tiles from another and a shower from somewhere else, you work with a designer who looks at the bathroom as one space.

  • How you use the room.
  • How you move through it.
  • What needs to be stored.
  • Where the light falls.
  • Which products will work together.
  • And importantly, what will actually fit.


Every bathroom is designed around the individual room, the people using it and the look you want to create. We then bring the design, product specification and supply together, with bathroom installation available through our own team.

Here is how the process works.

Step one: The design consultation

Every bathroom starts with a conversation.

Your designer will want to understand how you use the room, what is not working currently and what you would like to change. It is also the time to talk about your style, your priorities and your budget.

Bring your inspiration with you. Pinterest boards, Instagram screenshots, magazine pages, photographs or even a colour you keep coming back to can all help.

You can also visit our Putney or Guildford showroom and see products, tiles and finishes in person.

The aim at this stage is not to make every decision. It is to establish the direction for the room.

Step two: The site survey

Once we understand what you are looking for, one of our designers visits your home to survey the space and take detailed measurements.

This is where the design starts to become specific to your bathroom.

We look at the dimensions of the room, the position of doors and windows, existing plumbing, ceiling height and any awkward areas that could affect the layout.

It is an important part of the process because a bathroom can look very different in a photograph or on a floor plan than it does when you are standing inside it.

Accurate measurements allow your designer to create a design that works in the real space, not just on paper.

Step three: Your bathroom design in 2D and 3D

Now the ideas start to become a room.

Using detailed 2D and 3D design tools, your designer creates a visual representation of your proposed bathroom. You will also see a moodboard bringing together the tiles, furniture, brassware and finishes, alongside elevations that show the room from different angles.

This is one of the most useful parts of the design process because you can see how the individual choices work together.

A bathroom tile that looks beautiful on a small sample can feel very different across an entire wall. A vanity that looks perfect online might be too large for the room. A layout that seemed obvious at first might not give you the flow you need.

The 3D design gives you the opportunity to see those decisions before anything is ordered.

You can give feedback, your designer can make amendments and the design can be refined until everything feels right.

Once the final design is signed off, the detailed specification can be prepared.

Step four: Product specification and supply

A bathroom contains more products than you might realise.

There is the obvious stuff: the bath, basin, shower, toilet and vanity.

Then there are the details: taps, wastes, mirrors, shower screens, accessories, lighting, heating, tiles, adhesives, fixings and all the other components needed to bring the room together.

Your designer creates a detailed product specification so that everything has been accounted for.

At Kallums, we supply the products for the bathroom as part of the same process, working with a carefully selected collection of bathroom brands and suppliers.

That means your designer knows exactly what has been specified and can make sure the products work together as part of the overall design.

Step five: Delivery and installation

Once the design is finalised and the products have been ordered, the project moves from the drawing to the real room.

If you choose our installation service, the installation is managed by our experienced team from start to finish.

The installers work from the same design and product specification created during the design process, so there is a clear reference for how the finished bathroom should look and function.

Our team remains involved throughout the project, helping coordinate the different stages of the installation and making sure the details are followed through to completion.

Because the design and installation sit within the same team, there is also someone who understands the thinking behind the room from the very beginning.

And that matters.

A beautiful design is only successful if it works when it is built.

Frequently asked questions

How much does a bathroom design service cost?

The cost of a bathroom design service can vary depending on what is included and whether you are purchasing your products through the same company.

The design service includes the consultation, site survey, moodboard, CAD drawings, elevations and realistic 3D visuals, giving you the opportunity to see how your bathroom will come together before you make your final decisions.

If you are looking for a fully managed bathroom renovation, our complete project service includes the design, product supply, installation and project management, with typical full-bathroom projects ranging from £15,000–£20,000.

Of course, every bathroom is different. The final investment depends on the size of the room, products and finishes selected, tiling, bespoke elements and any plumbing, electrical or structural changes required.

Why use a bathroom design service?

You can, of course, choose your own products.

But designing a bathroom is rarely as simple as finding individual pieces that you like.

The basin needs to work with the vanity. The vanity needs to fit the room. The shower needs to work with the enclosure. The tiles need to work with the proportions of the space. The lighting needs to work with the finishes and the way you use the room.

Then there are the technical details that are much harder to spot from a Pinterest board.

A designer brings all of those decisions together.

The real value of a bathroom design service is not simply having someone choose products for you. It is having someone look at the entire room and make sure every decision has a reason behind it.

What should you look for in a bathroom design service?

Not all design services work in the same way.

Before choosing one, look at the experience behind the service as well as the finished bathrooms.

  • Can you visit a showroom and see products in person?
  • Will someone visit your home and measure the space?
  • Will you see your design in 3D before committing?
  • Is there a detailed product specification?
  • Who will manage the supply?


And what happens once the design is signed off?Most importantly, look at real projects.

A bathroom can look beautiful in a render. The real test is whether that design works when it meets an actual room, real plumbing, real products and everyday life.

That is where experience matters.

How long does a bathroom design service take?

Every project is different. The timeline depends on the size and complexity of the bathroom, the level of design work required and how quickly decisions are made.

The important thing is not to rush the design stage. It is much easier to change a layout, product or finish on a drawing than once it has been installed.

Do I have to use your installation service?

No. You can use our design and supply service and arrange your own installer.

If you would prefer one team to manage the project through to completion, our installation service can be added as part of your bathroom project.

Can I bring my own bathroom ideas?

Absolutely.

Pinterest boards, Instagram saves, magazine cuttings and photographs are all useful starting points. You do not need to arrive with a finished design. That is what your designer is there to help you develop.

Do you design bathrooms outside Putney and Guildford?

Yes. While our showrooms are located in Putney and Guildford, we design and supply bathrooms for clients across London and Surrey.

See your bathroom before you build it

The best part of a bathroom design service is being able to see the room take shape before the first tile is laid.

From the initial conversation and site survey to the 3D design, product specification and installation, every stage gives you another opportunity to make sure the bathroom works for you.

If you are planning a new bathroom, visit our Putney or Guildford showroom and talk to our design team about your space.
