Top 5 Mistakes to Avoid When Planning a Bathroom Redesign

Redesigning your bathroom is a powerful way to enhance your home’s value, functionality, and style. But with so many decisions to make – from layout to lighting – it’s easy to overlook crucial details. At Kallums Bathrooms, we believe great design starts with clarity. Here are the top five mistakes to avoid when planning your new bathroom.

Underestimating Storage Needs

Mistake: Choosing style-led fixtures but overlooking where everything will go.

Tip: Build storage into the design early – think recessed shelving, vanity drawers, and wall-mounted units. The most elegant bathrooms are also clutter-free.

Overlooking Lighting and Ventilation

Mistake: Relying on a single ceiling light or forgetting ventilation altogether.

Tip: Layered lighting creates depth and ambience – combine task lighting (for mirrors), ambient lighting (for mood), and natural light where possible. Good ventilation is equally crucial to prevent mould and protect surfaces over time.

Focusing Only on Aesthetics

Mistake: Choosing everything based on appearance without considering practicality or durability.

Tip: Striking design should never come at the cost of everyday function. Choose materials that are not only beautiful but also easy to maintain and built to last.

Going It Alone Without Expert Input

Mistake: Underestimating the value of professional guidance.

Tip: Even if you have a strong vision, working with experienced designers ensures you avoid costly oversights and gain access to solutions you may not have considered. From space planning to product selection, expert insight makes a measurable difference.

Ignoring the Flow of the Space

Mistake: Failing to plan around how you’ll actually move through and use the bathroom.

Tip: Think beyond fittings and finishes – consider the layout’s flow. Can doors open fully? Is there enough clearance around the toilet or shower? A well-planned layout makes the space feel bigger, more comfortable, and easier to navigate every day.

In Summary

A successful bathroom redesign blends vision with practicality. Avoiding these common mistakes will help ensure your new space feels as good as it looks – functional, timeless, and tailored to you.

Consultation

Planning your dream bathroom with our experts couldn’t be easier. First step, we invite you for a consultation. This allows us to get to know each other and clarify all your requirements and design ideas.

We will ask you personalised questions to really understand your taste and style.

You are welcome to share any bathroom images you might have found on social media or magazines, or wander around our stunning bathroom showrooms for inspiration.

Site Visit

To ensure accuracy and precision, one of our designers will come to your location to take detailed measurements of your space. This also allows us to really get a feel for your space, to understand the environment and ensures that every design element is perfectly tailored to fit.

Now that we understand your creative vision, we get started on creating the initial design. Everything discussed from the consultation is incorporated, whilst adding that special Kallums touch.

3D Design Tools

Once the design is ready, we will invite you back to our luxury bathroom showroom for a design presentation. We will talk you through the concept we have built, which includes realistic 3D design renders and moodboards. 

Next, we will ask for feedback, and make note of any amendments you might require. Smaller changes can be made during the discussion, while a full redraw may require more work. Once all amendments have been made the final bathroom design can be signed off.

Installation

With the bathroom design completed, we produce a detailed product specification. All products are specified and then placed on order. Delivery and installation are then arranged.

We will introduce you to experienced installers and provide them with a comprehensive design and installation pack, ensuring they have everything needed to bring your project to life. We will regularly check in on the progress at every stage to ensure perfection is maintained.
