Planning a bathroom renovation: 10 decisions to make before you start

A beautifully designed bathroom should feel effortless, but achieving that result requires careful planning.

From layout and lighting to materials and storage, the decisions you make before work begins can significantly influence the finished space, your budget and the overall renovation experience.

Here are 10 things worth considering before you start.

10 decisions to make before you start

1. Define your budget

Establish a realistic budget before approaching suppliers. Consider not just sanitaryware and finishes, but installation, plumbing, electrical work and potential structural changes.

Allow a contingency of around 10–15% for unexpected costs, particularly in older properties.

For more guidance, read our bathroom renovation cost guide.

2. Decide what isn't working

Think about what you'd like to improve in your existing bathroom.

Is there insufficient storage? Poor lighting? An awkward layout? Understanding your priorities will help your designer create a space that works for you.

3. Consider your layout

Moving a bath, shower or toilet can transform a space, but may also increase plumbing and installation costs.

An experienced bathroom designer can help you understand what's achievable and whether changing the layout is worthwhile.

4. Choose between a bath and shower

A freestanding bath can create a beautiful focal point, while a generous walk-in shower may offer greater everyday practicality.

Consider how you use the bathroom, the available space and whether you need both.

5. Think about storage

Good storage is essential to creating a calm, uncluttered bathroom.

Recessed shelving, vanity drawers and concealed cabinetry can provide practical storage without compromising the design.

6. Select materials carefully

Natural stone, porcelain, marble and specialist finishes can all create distinctive results.

Consider durability, maintenance, slip resistance and how materials perform in wet environments, not just their appearance.

7. Plan your lighting

Layered lighting can make a significant difference to both atmosphere and functionality.

Consider task lighting around mirrors, softer ambient lighting and feature lighting to highlight architectural details.

Ensure fittings are appropriate for their bathroom electrical zones.

8. Consider heating and ventilation

Underfloor heating, heated towel rails and effective ventilation can make your bathroom considerably more comfortable.

Good ventilation is particularly important for managing moisture and protecting finishes over time.

9. Understand the project timeline

Bathroom renovations involve several trades, often working in a specific sequence.

Ask your supplier about design approvals, product lead times, installation schedules and how unexpected issues will be managed.

10. Choose the right bathroom supplier

The right supplier can make the difference between a stressful renovation and a well-managed project.

Look for experience, design expertise, quality products and a clear understanding of your requirements.

Compare what's included in quotations, particularly design, installation and aftercare. Our guide to how to choose a bathroom supplier covers what to ask and how to compare proposals.
