How Much Does a Walk-In Shower Cost in the UK in 2026?
Updated: Aug 28
Written by the team at The Bathroom Project — hands-on bathroom, plumbing and heating specialists serving Bromley, Orpington and across Kent.
If you’re considering replacing your bath with a walk-in shower, one of the first questions you’ll probably ask is:
“How much does a walk-in shower actually cost?”
The answer depends on far more than the price of the shower itself.
A walk-in shower can be a relatively straightforward bathroom upgrade, or it can become a substantial renovation involving new plumbing, waterproofing, tiling, drainage, glass and flooring.
For homeowners in Bromley, Sevenoaks, West Malling and surrounding areas, we recommend looking at the whole installation, rather than simply comparing the price of individual products.
Quick answer: how much does a walk-in shower cost?
As a general 2026 planning guide:
Type of project
Typical planning budget
Simple walk-in shower installation
£4,000–£7,000
Premium walk-in shower
£6,000–£10,000+
Bath-to-walk-in shower conversion
£5,000–£9,000+
Wet-room style installation
£7,000–£12,000+
Full bathroom renovation including walk-in shower
£10,000–£20,000+
These are indicative planning figures rather than quotations.
The actual cost depends on the existing bathroom, layout, drainage, waterproofing, products, tiling and level of finish.
What is a walk-in shower?
A walk-in shower generally means a shower area with an open or minimally enclosed entrance rather than a traditional shower cubicle with a hinged or sliding door.
They can use:
Fixed glass panels
Low-profile shower trays
Linear drains
Wet-room floors
Concealed shower systems
Large-format tiles
Open shower entrances
The result can be a bathroom that feels larger, cleaner and more contemporary.
What does a £4,000–£7,000 walk-in shower typically involve?
A straightforward installation might include:
Shower tray
Fixed glass screen
Shower valve
Shower head
Shower handset
New pipework where required
Waterproofing
Wall tiling
Flooring
Shower controls
Installation and finishing
This type of project works particularly well when the existing bathroom layout can remain largely unchanged.
How much does it cost to replace a bath with a walk-in shower?
Typical planning budget: £5,000–£9,000+
Replacing a bath with a walk-in shower can be a very effective way of modernising a bathroom.
However, it isn’t always as simple as:
Remove bath → install shower.
The existing:
Waste position
Water supplies
Wall construction
Floor
Waterproofing
Tile layout
all need to be considered.
There may also be areas underneath or behind the bath that haven’t previously been finished to the same standard as the rest of the room.
This is why the cost should be assessed as an installation project, rather than simply the cost of the shower products.
What makes a walk-in shower more expensive?
1. Moving the shower
If the shower is staying in roughly the same position, installation may be relatively straightforward.
Moving it can involve additional:
Plumbing
Drainage
Wall preparation
Floor preparation
Waterproofing
Tiling
2. Waterproofing
Waterproofing is one of the most important parts of a shower installation.
A good-looking bathroom isn’t much use if water is allowed to penetrate behind the finished surfaces.
The shower area needs to be appropriately prepared and waterproofed for the installation.
3. The shower tray
There are many options, from standard shower trays to:
Low-profile trays
Stone-resin trays
Bespoke trays
Wet-room formers
Linear drainage systems
The choice affects both appearance and installation requirements.
4. Glass
Glass is one of the most visible parts of a walk-in shower.
You can choose from different:
Thicknesses
Finishes
Glass treatments
Panel sizes
Configurations
A large frameless panel can create a very clean appearance, but the installation needs to be carefully planned.
5. Tiling
Tiling can make a major difference to the final price.
There is a big difference between a simple ceramic tile and:
Large-format porcelain
Natural stone
Feature tiles
Herringbone layouts
Intricate patterns
Mitred corners
The tile itself is only part of the cost.
The preparation and installation also matter.
Walk-in shower or wet room — what’s the difference?
They’re often confused.
A walk-in shower can use a conventional shower tray with a fixed glass panel.
A wet room typically has a fully tanked shower area and a floor designed to direct water towards a drain.
A wet room can provide an extremely clean, open appearance, but it requires careful attention to:
Falls
Drainage
Waterproofing
Floor construction
Tanking
Glass
Tiling
A walk-in shower with a tray can sometimes achieve a similar visual effect with a simpler installation.
Is a walk-in shower suitable for a small bathroom?
Yes.
In fact, a well-designed walk-in shower can make a small bathroom feel considerably more spacious.
A large glass panel creates fewer visual barriers than a traditional enclosed shower.
However, the dimensions need to be carefully considered.
You need enough space for:
A comfortable showering area
Safe access
A suitable glass panel
Adequate water containment
A poorly planned walk-in shower can result in water escaping into the rest of the room.
What is the best size for a walk-in shower?
There isn’t one universal size.
The ideal dimensions depend on:
The bathroom layout
Glass configuration
Shower position
Drainage
User requirements
Available floor space
The important thing is to create enough usable showering space while controlling water spray.
Are walk-in showers good for accessibility?
They can be.
A walk-in shower can provide easier access than stepping over the side of a traditional bath.
For homeowners with mobility considerations, the design may incorporate:
Level or low-level access
Grab rails
Seating
Hand showers
Thermostatic controls
Easy-reach storage
However, accessibility requirements vary from person to person, so the bathroom should be designed around the actual user.
What should you spend money on?
If your budget is limited, we’d prioritise:
1. Waterproofing and preparation
Get the fundamentals right.
2. Drainage
Poor drainage can create significant problems.
3. The shower system
It’s something you’ll use every day.
4. Glass
It has a major impact on the appearance of the finished bathroom.
5. Installation
Quality installation matters more than choosing the most expensive products.
Can you install a walk-in shower without renovating the whole bathroom?
Sometimes.
If the existing bathroom is in good condition and the layout is suitable, a bath-to-shower conversion may be possible.
However, you’ll need to consider:
Existing tiles
Floor finishes
Waterproofing
Plumbing
Drainage
Shower location
Wall condition
Sometimes a wider renovation is actually more sensible because replacing only part of an old bathroom can leave you with mismatched finishes or inaccessible areas.
Is a walk-in shower worth the money?
For many homeowners, yes.
A well-designed walk-in shower can improve:
Accessibility
Appearance
Space
Ease of cleaning
Everyday usability
But the key is good design and installation.
A walk-in shower isn’t automatically better simply because it looks modern.
It needs to work properly for the room and the people using it.
How much does a walk-in shower cost in Bromley, Sevenoaks and West Malling?
Prices vary considerably depending on the existing bathroom and specification.
As a planning guide, homeowners should consider approximately:
£4,000–£7,000 for a straightforward installation.
£5,000–£9,000+ for a bath-to-walk-in shower conversion.
£7,000–£12,000+ for a more complex wet-room-style installation.
A complete bathroom renovation incorporating a walk-in shower can naturally be considerably more.
The only reliable way to establish the actual cost is to assess the existing room and agree the required specification.
