How To Remodel A Small Bathroom | Costs & Design Tips

Published: 9 April 2026

Remodelling a small bathroom can feel like a challenge. With limited space to work with, every decision matters — from layout and storage to fixtures and finishes.

The good news is that with the right planning and design approach, even the smallest bathroom can be transformed into a practical, comfortable and stylish space. The key is making the most of the space available and choosing features that improve both functionality and flow.

In this guide, we’ll walk you through everything you need to know, from first steps and layout planning to costs, timelines and clever design ideas.

First Steps: How To Plan Your Bathroom Remodel

Before choosing tiles or fittings, it’s important to get the basics right. A well-planned bathroom remodel will save time, reduce costs and help you avoid common mistakes.

Who Is The Bathroom For?

Start by thinking about how the space will be used. A busy family bathroom may need a bath and extra storage, while a guest en-suite might work better with a walk-in shower.

Understanding who will use the space — and how — will help guide decisions around layout, storage and fixtures from the very beginning.

Assess The Existing Layout

In a small bathroom, layout is everything. Keeping key fixtures like the toilet and basin close to existing pipework is often the most cost-effective option.

Moving plumbing in a compact space can quickly increase costs and complexity, so it’s usually best to work with the existing layout where possible.

Measure The Space

Take accurate wall-to-wall measurements and note the position of doors, windows and any awkward features such as sloping ceilings.

This will help determine what can realistically fit in the room and ensure your design works in practice, not just on paper.

Small Bathroom Design Tips & Ideas

When space is limited, clever design choices can make a huge difference. The key is to maximise usability while creating a layout that feels open, practical and comfortable. Even the smallest bathrooms can feel more spacious with the right combination of layout, light and design features.

Maximise Storage

Wall-hung vanity units, recessed shelving and built-in storage help keep the floor clear, making the room feel more open and less cluttered.

Keeping everyday items organised and off surfaces is one of the simplest ways to improve both functionality and the overall look of a small bathroom.

Choose Compact Sanitary Ware

Look for short projection toilets, compact basins and slimline furniture designed specifically for smaller spaces.

Choosing sanitaryware that’s proportioned for compact layouts can make a significant difference, helping you maximise usable space while maintaining comfort and functionality.

Swap a Bath for a Shower

If space is tight, replacing a bath with a walk-in shower or wet room can open up the room and make it feel significantly larger.

Wet rooms reduce visual barriers and create a more open layout, helping compact bathrooms feel less enclosed. For more inspiration, explore our guide to small wet room ideas.

Consider Space-Saving Heating

Underfloor heating removes the need for bulky radiators, freeing up valuable wall space and creating a cleaner, more streamlined finish. It also helps distribute heat evenly, which can make smaller bathrooms feel more comfortable.

Use Light, Mirrors and Reflection

Large mirrors, glossy finishes and light colour palettes help reflect light around the room, creating the illusion of more space.

Using consistent tones across walls and floors can also help the room feel more cohesive and open. Even small design choices — such as mirror placement or wall finishes — can make a noticeable difference.

Use Sliding or Bi-Fold Doors

Traditional doors can take up valuable space. Sliding or bi-fold doors can improve access and make smaller bathrooms easier to navigate, which is particularly useful in tight layouts where every inch of space counts.

Consider Shower Room Layouts

In very compact spaces, converting to a shower room can often provide the most efficient layout. By simplifying the design and focusing on essential features, you can maximise both space and usability.

Careful layout planning — such as keeping plumbing grouped together, using frameless glass panels and maintaining clear sightlines — can make even the smallest shower room feel more open and functional.

Plan Around Your Layout

In smaller bathrooms, working with your existing layout is often the most effective way to maximise space and control costs.

Keeping key fixtures close to existing pipework helps simplify the design while still achieving a practical and stylish result. For more planning advice, read our guide on how to remodel a small bathroom.

How Long Does It Take To Remodel A Small Bathroom?

A typical full small bathroom remodel usually takes around 1.5 to 2.5 weeks when completed by professionals, although this can vary depending on the scope of work and complexity of the design.

Most projects follow a structured installation process, with each stage carefully planned to ensure everything runs smoothly:

Day 1–3: Removal of the existing bathroom and first fix plumbing and electrics
Day 4–7: Plastering, boarding, waterproofing (tanking) and tiling
Day 8–11: Installation of sanitary ware, flooring and second fix work
Final days (up to Day 12–15): Finishing touches, sealing, testing and final clean

In smaller bathrooms, precision is key. Working in a compact space often requires careful coordination between trades to ensure everything fits and functions correctly.

Timelines can vary depending on factors such as drying times, material availability, access to the property and whether any layout or plumbing changes are required. Unexpected issues, such as hidden pipework or structural adjustments, can also extend the schedule slightly.

How Much Does It Cost To Remodel A Small Bathroom?

The cost of remodelling a small bathroom can vary depending on the layout, materials and level of finish. Having a realistic budget in mind from the outset can help guide your decisions and avoid unexpected costs.

Cost Guide

A basic refresh or DIY-style update may cost £3,000–£5,000
A professionally installed small bathroom typically ranges from £6,000–£10,000+
Higher-end designs with premium finishes will typically exceed £10,000, with many projects averaging between £12,500–£15,500

The overall cost of any bathroom remodel will always depend on the choices you make. Factors such as the level of tiling, quality of fixtures, layout changes and finishing details can significantly influence the final price, regardless of the starting budget.

While smaller bathrooms may use fewer materials, the labour involved is often similar to larger spaces, which is why overall costs don’t always reduce significantly.

What Affects The Cost?

Labour

Labour is often the largest part of the cost, particularly when plumbing, electrics and tiling are involved.

Tiling

The amount and type of tiling can significantly impact the budget. From full rooms to half rooms, ceramic tiles to porcelain and even marble, each of these considerations can substantially alter the final cost and should be carefully considered.

Layout Changes

Moving pipework, especially waste pipes, can increase both the cost and complexity of the project.

Fixtures and Finishes

The quality of your chosen fixtures, brassware and furniture will also influence the final cost.

Small Bathroom Remodel FAQs

Can you put a walk-in shower in a small bathroom?

Yes, replacing a bath with a walk-in shower or wet room is one of the most effective ways to create more space and improve usability.

Does a small bathroom cost less to remodel than a large one?

Generally, yes. There is less area to tile and fewer materials required. However, labour costs for plumbing and electrics are often similar regardless of room size.

What colours make a small bathroom look bigger?

Light, neutral colours such as white, cream and soft greys reflect light and help create a more open feel. Using consistent tones across walls and floors can also make the space feel larger. For more ideas and inspiration, explore our bathroom colour guide.

Can I remodel a small bathroom myself?

While cosmetic updates like painting or replacing fixtures can be done yourself, a full remodel involving plumbing, electrics and waterproofing is best handled by professionals.

How do you fit a bath in a small bathroom?

If you can’t live without a bath, consider a shower-bath combination (such as P-shaped or L-shaped baths) or compact bath designs specifically created for smaller spaces.

Do I need planning permission for a bathroom remodel?

In most cases, no. Internal bathroom renovations do not require planning permission unless your property is listed. However, building regulations may apply in certain situations.

How do you ventilate a small bathroom without a window?

A high-quality extractor fan is essential to remove moisture and prevent mould. Options include fans with timers or humidistats that activate automatically when humidity rises.
