If you’re wondering whether it’s possible to replace your bath with a shower in a small bathroom, the answer is a confident yes. Many UK homes, especially older properties, have compact bathrooms where space is limited. Fortunately, modern plumbing solutions and clever design innovations have made bath-to-shower conversions not only possible but highly practical — even in the smallest of spaces.
Whether you’re hoping to create a more accessible bathroom or simply want a more modern, space-saving alternative to your current setup, this guide explains how a professional plumber can help you make the switch.
Why Consider Replacing a Bath with a Shower?
Swapping a bathtub for a shower brings several advantages:
-
Saves Space: A shower enclosure or walk-in shower typically takes up less room than a standard bath, making your bathroom feel more open and less cramped.
-
Increased Accessibility: For older adults or people with mobility issues, a step-free or low-threshold shower is easier and safer to use than a bath.
-
Modern Look: A sleek, well-designed shower area can transform the feel of your bathroom and add value to your property.
-
Water Efficiency: Showers often use less water than a full bath, making them a more eco-friendly and cost-effective choice.
Is Your Bathroom Too Small for a Shower?
Many people worry that their bathroom is too small to accommodate a proper shower. However, experienced bathroom fitters are used to working with awkward layouts and limited space. Even in the tightest bathrooms, a tailored solution can usually be found. Some key considerations include:
1. Shower Type
There are several compact shower options to choose from:
-
Corner showers: These fit neatly into the corner of a room and are ideal for tight layouts.
-
Walk-in showers: With a level-access floor and minimal glass panels, walk-ins offer a clean, modern look and maximise the feeling of space.
-
Wet rooms: A completely open-plan shower area with waterproofed walls and floors. Perfect for small bathrooms if done properly.
2. Shower Tray Size
Shower trays come in a wide range of shapes and sizes. A standard bath is typically around 1700mm in length, but even if your space is smaller than this, there are plenty of compact trays from 760mm x 760mm upwards.
3. Wall Panels or Tiles
In small bathrooms, wall panels can be a smart alternative to tiles. They’re quick to install, easy to clean, and help to create a streamlined look that makes the room appear larger.
4. Glass Options
Using clear glass for your shower screen allows light to travel freely through the room, preventing the space from feeling boxed in.
What’s Involved in the Conversion?
Replacing a bath with a shower in a small bathroom typically involves:
-
Removing the Existing Bath
The old bathtub and associated plumbing are safely disconnected and removed. -
Assessing the Plumbing
Your plumber will check the pipework and waste positioning. In most cases, adjustments are straightforward. -
Installing the New Shower
Whether you opt for a tray-based shower, walk-in enclosure or wet room, the new unit will be fitted along with necessary drainage and waterproofing. -
Wall and Floor Finishing
Choose from modern PVC wall panels, tiling, or waterproof flooring for a clean, polished finish. -
Optional Accessibility Features
If required, grab rails, anti-slip flooring, and shower seating can be installed to make the bathroom safer and more comfortable.
Do You Need Planning Permission?
In most cases, no planning permission is required to replace a bath with a shower, even in a small bathroom. However, if your property is listed or within a conservation area, it’s best to check with your local authority or ask your bathroom installer for advice.
How Long Does a Bath-to-Shower Conversion Take?
The timeline will depend on the specifics of your space and what level of work is needed, but a typical installation in a small bathroom takes:
-
1–2 days for a basic shower replacement using existing plumbing and wall panels.
-
3–5 days if additional plumbing, tiling, or wet room flooring is required.
Is a Shower Safer for Small Bathrooms?
Absolutely — in fact, safety is one of the main reasons many homeowners make the switch. Especially in tight spaces, climbing in and out of a bath can be a fall risk. A level-access shower with anti-slip flooring and grab rails can provide much-needed reassurance for elderly users or those with disabilities.
