Walk-In Shower Screens Planned and Installed Properly
A walk-in shower can look beautifully simple, but the glass length, entrance, shower-head position, support and drainage must work together. Send the proposed layout or product before ordering and we will help identify the practical installation route.
Will a Walk-In Shower Screen Work in Your Bathroom?
A panel can fit the tray perfectly and still be wrong for the shower. The starting point is where the water comes from, where the user will stand and how much practical entrance remains after the glass is positioned.
Shower position
Where is the overhead head or handset relative to the open end?
Glass length
Will the panel extend beyond the normal direct spray and splash zone?
Entrance
Can the user enter comfortably after the panel or return is installed?
Support
How will the exposed glass edge be restrained during use and cleaning?
Drainage
Do the floor falls and waste deal with the water delivered by the shower?
Begin with the shower head—not the tray label
The nominal tray size tells us how much space may be available, but it does not show where the spray will land. We start with the shower-head position, then consider the user, splash, bounce and the entrance needed for everyday use.
The best answer may be a longer fixed panel, a hinged return, a different shower-head direction or a more enclosed shower. The most visually minimal arrangement is not always the arrangement that will control water best.
Standard Panel, Return Panel or Bespoke Walk-In Glass?
Bespoke glass is not automatically better. A good manufactured panel is often the quickest and most economical solution where its size, support system and adjustment suit the finished bathroom.
Manufactured fixed panel
Suitable where the standard dimensions, wall adjustment, glass length and supplied support arrangement all suit the room.
View branded screens →Panel with support arm
A conventional and dependable arrangement that reduces movement at the exposed glass edge during cleaning, use and accidental contact.
Fixed return panel
Adds a permanent turn at the open end. It can redirect splash and may also contribute to the restraint of the main panel.
Hinged return panel
Extends the effective screen length while showering, then folds in or out to provide simpler entry, cleaning and use of the room.
Made-to-measure fixed panel
Useful where a straightforward rectangular panel needs a particular finished width or height that standard glass cannot provide.

View bespoke process →How Long Should a Walk-In Shower Screen Be?
There is no single panel length that guarantees containment in every bathroom. As a practical installer-led starting point, around 1200mm is often a useful middle ground for a conventional single-entry walk-in shower.
The final decision should still begin with the shower-head position. A powerful handset, high flow rate, user standing near the entrance or a shower head aimed towards the open end can send water beyond a panel that works perfectly in another bathroom.
Shorter panels can work. From approximately 800mm onwards, SSI has seen practical arrangements perform where a suitable diverter panel, careful shower positioning and realistic expectations are included. The complete layout matters more than the panel width in isolation.
- The panel should extend beyond the normal spray zone
- The shower head should not normally aim towards the open end
- Handset use must be considered separately from an overhead head
- A return can improve control without adding a full shower door
- The remaining entrance must still be practical
Do not choose the glass length from appearance alone
Send the tray or floor dimensions, shower-head position and proposed product. A quick review before ordering can prevent an expensive panel that looks excellent but finishes inside the working splash zone.
Test the Water Pattern Before Ordering the Glass
A sheet of Corex can create a temporary water template of the proposed screen. A full sheet is commonly around 2400 × 1200mm and can often be purchased for approximately £10.
- Cut or position the sheet to represent the proposed fixed glass.
- Tape it securely where the final panel would stand.
- Run the overhead shower and handset in the way they will actually be used.
- Check where spray and water from the user’s body reach the open end.
- Adjust the temporary panel or entrance to compare different arrangements.
This test helps assess spray coverage and entrance position. It does not test glass support, structural fixing, sealing, waterproofing, floor construction or drainage capacity.
Fixed Return or Hinged Return Panel?
On many rectangular-tray layouts, a return of approximately 200mm can make a useful practical difference. The best type depends on the permanent entrance, cleaning access and how the shower will be used.
Fixed return panel
A fixed return creates a permanent turn at the open end of the main glass. It has no moving hinges and can contribute to both splash deflection and panel restraint.
- Always remains in the correct water-control position
- Can strengthen the complete glass arrangement
- Simple construction with no moving return hinge
- Permanently reduces the clear entrance
Hinged return panel
A hinged return—also called a diverter or deflector—extends the effective screen length while showering and can fold away when wider access or cleaning space is needed.
- Allows the principal fixed panel to be shorter
- Useful where permanent space is limited
- Can swing inward and outward where the product permits
- Must be left in the useful position while showering
Jack-and-Jill and Double-Entry Walk-In Showers Often Need Much More Glass
A central panel with an entrance on both the left and right can look outstanding in a plan or showroom. SSI has also seen this layout fail many times once the shower is turned on.
A 1200mm central screen may intercept the direct overhead spray, but the user stands close to both open ends. Water can run from the arms and elbows and escape around either side of the glass—even when the shower head points straight down.
In practice, these layouts may need approximately 1500–1800mm of effective glass coverage to provide useful containment. At that size, the arrangement is beginning to operate more like a partial enclosure than a genuinely open walk-in shower.
- Test both open ends with the Corex method
- Consider the user’s body position, arms and elbows
- Allow for the handset as well as the overhead head
- Consider a single entrance or more enclosed alternative
Will a Walk-In Shower Screen Leak?
A properly planned and installed walk-in panel manages normal spray and running water. It does not create the same enclosed environment as a framed cubicle, sliding enclosure or bypass door system.
A walk-in screen can manage
- Direct spray intercepted by the glass
- Water reaching correctly sealed fixed joints
- Normal splash redirected by a suitable return
- Normal water flow cleared by a suitable waste
- Everyday use within the planned shower zone
It cannot guarantee against
- Water deliberately directed through the entrance
- A handset used close to the open end
- Floor falls carrying water into the bathroom
- A tray filling faster than it drains
- Every droplet leaving an intentionally open shower
Do not overlook the waste, flow rate and floor falls
A blocked or partially restricted waste can allow the tray or wet-room area to fill faster than it drains. High-flow rainfall heads, pumps and several outlets running together can also exceed the practical capacity of an older or restricted drainage arrangement.
Water may then pass over tracks, seals, low thresholds, tray edges or open ends even where the glass and installation are otherwise correct. No additional silicone can compensate for a shower area that is filling faster than the waste can clear it.
SSI does not calculate shower output against drainage capacity as part of an ordinary glass installation. Plumbing flow, waste capacity, waterproofing and floor falls remain the responsibility of the relevant plumber or bathroom contractor unless specifically included in the agreed work.
A real drainage problem that looked like a glass problem
On one installation, the water could visibly be seen rising inside the glass while the shower door was closed. The glass was not allowing spray through an opening—the incoming flow and pressure were exceeding the practical drainage arrangement. Pressure regulation was required. A new seal or more silicone would not have solved it.
Does a Fixed Walk-In Panel Need a Support Arm?
SSI normally begins by recommending a support arm or another suitable restraint for fixed glass. A free glass edge can move during cleaning, normal use and accidental contact.
This does not mean every unsupported panel is automatically unsafe. Properly specified bespoke panels have proven capable of working without a visible arm at widths up to approximately 900mm, but that is not a universal rule and should never be decided from width alone.
For standard manufactured products, SSI follows the manufacturer’s stated support arrangement. A supplied support component should not be removed simply to make the installation look more minimal.
Support is part of the glass specification
Panel width, height, glass thickness, channels, clamps, wall construction, floor fixing and any connected return or door all affect the decision. Where support is recommended and declined for design reasons, the recommendation and decision should be recorded.
Entrance Width, Glass Thickness and Installation Surface
The correct panel is not determined by appearance alone. It must remain usable, suitable for its fixing system and appropriate for the finished tray or wet-room floor.
| Decision | SSI practical position | Important boundary |
|---|---|---|
| Entrance width | A 450mm entrance can be physically usable, including for a larger adult entering sideways. | Physical access is not the same as comfortable or accessibility-led access. More width is preferable where the room permits. |
| 6mm glass | Available in some manufactured systems, but not SSI’s normal preference for a substantial walk-in panel. | The complete manufacturer system and maximum size remain more important than thickness alone. |
| 8mm glass | SSI’s preferred practical minimum for most manufactured walk-in panels. | Use the exact support and fixing method stated for that product. |
| 10mm glass | The usual preferred thickness for bespoke fixed panels and full-height arrangements. | It does not automatically remove the need for support. |
| 12mm glass | Reserved for particularly large, demanding or specification-led glass. | Greater thickness adds weight and changes handling and hardware requirements. |
| Tray installation | Suitable where the tray is secure, correctly positioned and compatible with the product fixing method. | Tray level, upstands, tile position and available fixing zones must be considered. |
| Wet-room floor | Glass can be installed directly to the tiled floor using an appropriate channel, clamp or approved system. | Falls, waterproofing, drainage and underfloor services are part of the wider bathroom construction. |
Can the Glass Reach the Bathroom?
A large panel may fit the shower but be unable to pass through the property. Toughened glass cannot be cut, trimmed or reduced after manufacture.
- Front door and hallway
- Staircase, landing and ceiling height
- Tight turns and loft stairs
- Bathroom doorway
- Space to rotate and stand the panel upright
Underfloor Heating and Floor Fixings
SSI asks the homeowner, developer or relevant contractor whether underfloor heating is present, what type it is and, where known, the approximate depth and route.
Mechanical fixing is preferred where suitable and safe. Where floor drilling should be avoided, an alternative design may use wall, top or ceiling restraint, or an approved silicone, tape or adhesive method where the manufacturer or hardware system permits it.
Customer-Supplied, Standard Supply or Fully Bespoke
SSI can work from a panel you have already selected, recommend and supply a suitable manufactured product, or manage the complete bespoke glass process where standard products cannot provide the required result.
Customer-supplied installation
Send the exact model or product link, panel dimensions, support components and photographs of the finished bathroom before booking.
Recommended and supplied panel
SSI can suggest and supply a suitable manufactured screen where the available sizes, return options and support system work for the room. MERLYN is often a preferred route, but the specification remains project-led.
Fully managed bespoke glass
Preliminary concept, component recommendation, professional survey, final CAD manufacturing drawing, glass supply, installation, sealing and handover.
What is checked for a customer-supplied panel?
- Exact manufacturer, model and product instructions
- Panel dimensions, glass thickness and handing
- Finished wall, tray or floor conditions
- Supplied arm, channel, return and fixing components
- Access route and safe glass handling
- Visible damage or missing components
If the supplied product is damaged, incomplete, incorrectly measured, unsuitable for the opening or impossible to carry into the room, the customer is informed before work continues. Additional attendance or return work may be chargeable and is handled reasonably case by case.
How the Walk-In Screen Process Works
The exact route depends on whether the glass is already purchased, requires standard product selection or needs a professional bespoke survey.
Send the layout
Share photographs, dimensions, shower-head position, product details and the installation postcode.
Check the route
SSI considers panel length, entrance, returns, support, surfaces, access and whether standard or bespoke glass is more appropriate.
Confirm the work
The agreed product or bespoke specification, responsibilities, access and installation scope are confirmed before attendance or manufacture.
Install and hand over
The glass is positioned, fixed, aligned and sealed, followed by care advice and confirmation of the silicone curing period.
Bespoke survey and CAD route
For bespoke work, SSI first provides a preliminary concept and approximate direction. Once agreed, a professional survey—normally approximately £120–£150—covers travel, accurate measurement, laser-level assessment, CAD drawing and recommended glass and components. The survey is non-committal and may be used with another supplier.
Typical fitting time
A straightforward fixed walk-in panel commonly takes approximately one to two hours, subject to glass size, access, drilling surface, support components and installation complexity.
Two-person glass handling
SSI uses two installers for most substantial glass work. This improves carrying, positioning, equipment handling and protection of both the glass and the customer’s property.
Silicone cure time
Allow at least 24 hours before using the shower unless the sealant, screen or hardware manufacturer states a different curing period. The correct waiting time is confirmed at handover.
A balanced DIY position
A technically capable person can install a walk-in panel successfully. Professional fitting becomes more valuable as the glass becomes larger, heavier, more expensive or dependent on several precise components.
Cleaning
Use a squeegee after normal use and a soft, non-abrasive cloth for cleaning. Avoid aggressive chemicals on easy-clean coatings, seals and coloured hardware, and follow the product care instructions.
Ongoing checks
Keep channels and seals clean. If a return hinge, support component or fixed panel begins to move, arrange an inspection rather than forcing or repeatedly flexing the glass.

Frequently Asked Questions
Practical answers about glass length, returns, support, water control, drainage, access, installation and using customer-supplied panels.
What size walk-in shower screen do I need?
The useful size depends on the shower-head position, spray direction, user position, tray or floor length, entrance width, flow rate and whether a return panel is included. Around 1200mm is often a practical starting point for a conventional single-entry layout, but it is not a universal minimum or guarantee.
Is an 800mm walk-in shower screen long enough?
It can be in the right arrangement. SSI has seen panels from around 800mm work where a suitable diverter or return, shower position and spray direction are carefully considered. An 800mm panel used alone beside a powerful shower may allow substantial water past the end.
Will water go past the end of a walk-in screen?
Some water can leave any intentionally open shower. The aim is to extend the glass beyond the normal spray and splash zone. A longer panel, fixed or hinged return, revised shower-head direction or more enclosed design may be required where water containment is critical.
What is the Corex test for a walk-in shower?
A sheet of Corex can be temporarily taped where the proposed glass would stand. Run the overhead shower and handset and check where the spray reaches. It creates a low-cost water template before expensive toughened glass is ordered, although it does not test structural support, waterproofing or drainage.
Do I need a return panel?
Not always. A return is useful where the main panel alone does not extend far enough beyond the splash zone. On many rectangular-tray layouts, a return of approximately 200mm can make a useful difference, subject to the shower position and remaining entrance width.
Is a fixed or hinged return panel better?
A fixed return remains permanently in its water-control position and may contribute to panel restraint. A hinged return can extend the effective screen while showering and fold in or out for easier entry and cleaning. The better option depends on the permanent entrance, support system and everyday use.
Do Jack-and-Jill walk-in showers work?
They can, but double-entry layouts are difficult to contain. Water can run from the user’s arms and elbows around both open ends even when a 1200mm central panel intercepts the direct overhead spray. Approximately 1500–1800mm of effective glass coverage may be needed, at which point the arrangement begins to behave like an enclosure.
Does a fixed walk-in panel need a support arm?
SSI normally recommends a support arm or another suitable restraint. For manufactured products, the specified support system should be followed. Some correctly designed bespoke panels can work without a visible arm, but the decision depends on width, height, thickness, channels, fixing surfaces and the complete glass arrangement.
Can a full-height walk-in screen be installed without a visible support arm?
Sometimes. A bespoke full-height panel may be restrained through suitable wall, floor and ceiling channels or fixings. The ceiling, structure, dimensions, glass thickness and hardware must all be designed for that arrangement. It does not mean every tall panel can simply be fitted unsupported.
What glass thickness is best for a walk-in shower screen?
SSI generally prefers at least 8mm glass for a substantial manufactured walk-in panel and commonly uses 10mm for bespoke fixed glass. Twelve-millimetre glass is normally reserved for larger or specification-led projects. Thickness alone does not determine the required support or overall quality.
Can a walk-in screen be fitted directly to a tiled wet-room floor?
Yes, where the finished floor, waterproofing, falls, fixing zones and selected channel or clamp system are suitable. Any underfloor heating or concealed services should be identified before floor drilling. Alternative restraint may be considered where drilling should be avoided.
Can a blocked waste make a walk-in screen appear to leak?
Yes. If the tray or wet-room area fills faster than it drains, water can pass over thresholds, tray edges or open ends even when the glass is correctly installed. Waste capacity, shower flow and floor falls should be checked by the relevant plumber or bathroom contractor.
Can SSI install a walk-in screen I have already purchased?
Yes, subject to checking the exact product, dimensions, finished bathroom, support components, access and installation instructions. Send the product link or model, photographs, dimensions and postcode before booking. If the product is damaged, incomplete or unsuitable, SSI will explain the issue before continuing.
How long does a fixed walk-in screen take to install?
A straightforward fixed panel commonly takes approximately one to two hours. Larger glass, difficult access, porcelain or stone drilling, returns, ceiling support and multi-panel arrangements can take longer.
When can I use the shower after installation?
Allow at least 24 hours after the final silicone is applied unless the sealant, screen or hardware manufacturer specifies a different curing period. SSI confirms the appropriate waiting time at handover.
Send the Screen, Shower Position and Bathroom Details
Include a wide photograph, tray or floor dimensions, shower-head position, proposed product link and postcode. SSI can then advise on the likely panel length, return, support and installation route.
