Shower Screen Advice Before You Buy or Install
Clear, practical guidance on choosing the right screen, checking whether it will fit and preparing the bathroom for a successful installation.
You do not need to understand adjustment ranges, glass support, seals or specialist hardware before contacting us. This page will answer many common questions, and a brief WhatsApp chat or email will usually clear up anything specific to your bathroom.
That is normally enough to begin a useful conversation. Do not worry if the measurements are only approximate at this stage.

Which stage has your bathroom reached?
The right next step depends on whether the screen has already been chosen, supplied or still needs to be designed around the finished space.
I have not bought a screen
Send photographs, approximate measurements and any products you are considering. We can help identify obvious concerns before you order.
Check before buyingI already have the screen
Send the product link, exact model or box label together with photographs of the bathroom and the finished opening.

The room may have an unusual width, reduced height, sloping ceiling, half wall, uneven surface or restricted door clearance.
Explore non-standard screensI need to replace an old screen
Replacement involves more than matching the old size. Existing holes, silicone, surfaces and the new product all need to be considered.

This helps us assess travel, availability and the appropriate service route.
What Should I Check Before Buying a Shower Screen?
A shower screen may look correct online but still be unsuitable for the finished bathroom. The technical dimensions and fitting requirements are usually more important than the simplified product title.
Measure between the completed tiled or panelled surfaces.
Check the manufacturer’s exact minimum and maximum fitting sizes.
Measure at several heights because the opening may become wider or narrower.
Poor levels can affect doors, seals, tracks and water containment.
Check toilets, basins, radiators, handles, ceilings and walking space.
Confirm left-hand, right-hand or reversible operation before ordering.
Profiles, hinges, channels and clamps need suitable fixing positions.
Consider the shower-head position and where the main spray will travel.
Make sure the panel can pass through doors, stairs, landings and turns.
Check boxes, profiles, seals, rollers, hinges, handles and fixings.
Installer’s tip: do not order from the tray label alone
A tray described as 900 mm does not automatically leave a 900 mm finished opening. Wall boards, tile adhesive, tiles and the position of the walls can all reduce the usable dimension.
How to Avoid the Four Most Common Shower Screen Buying Mistakes
These mistakes are usually avoidable when the complete bathroom is considered before the product is ordered.
The opening was measured incorrectly
This is the most common problem. Customers may use the nominal tray size, take only one measurement or measure before the walls are tiled.
The completed opening should be measured at several positions and compared with the exact adjustment range of the chosen product.
The door hits the bathroom fittings
Hinged and pivot doors are often bought without checking the complete swing against toilets, basins, vanity units, radiators or towel rails.
Mark the likely door movement on the floor before ordering and allow comfortable access, not merely a narrow technical clearance.
The glass will not reach the room
A large panel may fit the shower perfectly but still be unable to pass through the front door, hallway, stairs, landing or bathroom doorway.
Toughened glass cannot be bent, trimmed or reduced after manufacture, so the complete carrying route must be checked.
The screen is too short for the shower spray
A minimal panel may look excellent on a drawing but allow water to pass beyond the end of the glass during normal use.
The screen must extend far enough to intercept the likely spray. A longer panel, return panel, relocated shower head or enclosed design may perform better than the most visually minimal option.

Do I Need a Standard, Special-Size or Bespoke Shower Screen?
Bespoke glass is not automatically the best option. A suitable standard screen is often quicker, simpler and more economical.
Standard product
Best where the opening fits the manufacturer’s adjustment range and the chosen door or panel works with the bathroom layout.
Special-size product
Some manufacturers offer reduced heights, wider adjustment, special widths or less common enclosure formats.
Made-to-measure panel
Useful where a simple fixed panel needs to match a finished dimension that standard glass cannot cover properly.
Fully bespoke glass
Appropriate for shaped panels, sloping ceilings, half walls, doors and several pieces of glass that must work together.
Which Type of Shower Screen Is Suitable for My Bathroom?
The best arrangement should suit the available space, access, spray direction and expected daily use—not just the preferred appearance.
Fixed walk-in panel
A clean and open arrangement with few moving parts.
- Often suits
- Longer trays, wet-room floors and bathrooms with generous access.
- Check carefully
- Panel length, support, shower position and splash beyond the glass.
Hinged or pivot door
Provides useful access where there is room for the door to move.
- Often suits
- Recesses and enclosures with clear space outside the shower.
- Check carefully
- Door swing, handle clearance, hinge support and nearby sanitaryware.
Sliding or bypass enclosure
Avoids an outward door swing and generally offers very good water containment.
- Often suits
- Rectangular trays, recesses and bathrooms with restricted floor space.
- Check carefully
- Entry width, roller access, frame adjustment and component assembly.
Bi-fold door
Reduces the space required for opening while retaining useful entry access.
- Often suits
- Smaller bathrooms and layouts where a full hinged door is impractical.
- Check carefully
- Fold direction, mechanism quality, clear entry width and adjustment.
Quadrant or corner enclosure
A practical manufactured solution where the tray and enclosure match correctly.
- Often suits
- Corner installations and bathrooms needing a compact enclosed shower.
- Check carefully
- Exact tray radius, wall dimensions, adjustment and model compatibility.
Bespoke door and panels
Designed around the finished opening where standard products cannot provide the required shape, size or layout.
- Often suits
- Sloping ceilings, half walls, unusual widths and architect-led bathrooms.
- Check carefully
- Finished surfaces, support, hinge loading, access and drawing approval.
Will a Properly Installed Shower Screen Leak?
The direct answer
A correctly selected and properly installed shower enclosure should provide very good water containment. Framed enclosures, sliding doors and bypass systems are generally particularly effective when the bathroom is built correctly and the screen is fitted and sealed in accordance with the manufacturer’s instructions.
Water escaping does not automatically mean that the glass or enclosure is faulty. The product, bathroom construction, installation, shower position, water flow and drainage all need to work together.
Water can escape because of:
- Incorrect product size or adjustment
- Door or frame misalignment
- Missing or incorrectly fitted seals
- Silicone applied in the wrong position
- Tray or shower floor level problems
- Incorrect floor falls
- Water aimed directly at a gap or opening
- A walk-in panel that is too short
Do not overlook the drain and water flow
A blocked or partially blocked waste can allow water to build up inside the tray or shower area. Once the water level rises, it may pass over seals, tracks, thresholds or open edges even though the enclosure and installation are otherwise correct.
High-flow rainfall showers, powerful pumps and several outlets working together can also deliver more water than an older or restricted waste system can remove.
- Water remains in the tray after showering
- The tray visibly fills while the shower runs
- The waste drains slowly or gurgles
- Hair, soap or debris may be restricting the trap
- The issue worsens when several outlets are used
- The water flow exceeds the practical waste capacity
A shower screen manages spray and normal running water. It cannot compensate for a tray that is filling faster than it can drain.
Walk-in screens work differently
A walk-in panel manages water through its length, position, shower-head direction and the fall of the shower floor or tray. It does not create the same enclosed environment as a framed cubicle.
The glass must extend far enough to intercept the normal spray. The most visually minimal panel is not always the most practical choice.
Do I Really Need a Shower Screen Support Arm?
SSI normally recommends supporting a fixed glass panel unless the complete design, fittings and fixing surfaces are suitable without one.
A free glass edge can flex or move during cleaning, normal use or accidental contact. A support arm reduces that movement and gives the installation additional stability.
Properly specified and correctly installed bespoke panels have proven capable of working without a visible arm at widths up to approximately 900 mm. That is not a universal rule.
The decision also depends on panel height, glass thickness, the channel or clamp system, the wall structure, exposed edges and whether a moving door is connected to the panel.
When support is declined
Some customers prefer to omit a recommended support arm for design reasons. The recommendation and the customer’s decision should then be recorded in writing so that responsibility for that design choice is clear.
A suitable support arm can often be retrofitted later if movement becomes a concern.

Can I Install a Shower Screen Myself?
Yes. A technically capable person can successfully install a shower screen, and we have seen some excellent DIY installations—including bespoke glass.
DIY can be a sensible route when:
- The installer is technically confident
- The manufacturer’s instructions are followed precisely
- The screen is manageable in size and weight
- The opening is suitable and correctly measured
- The wall construction and service positions are understood
- The correct drilling and handling equipment is available
- Glass can be moved safely without twisting or impact
Professional fitting becomes more valuable when:
- The glass is large, heavy or expensive
- The product is bespoke
- A moving door is supported by fixed glass
- The surfaces are porcelain, stone or large-format tile
- The adjustment range is limited
- Several panels or components must align accurately
- The installation route into the room is difficult
What can go wrong?
Poor installation can result in cracked tiles, incorrect holes, scratched frames, excessive or missing silicone, door misalignment, damaged seals and chipped or broken glass.
The question is not only whether DIY fitting is possible. It is whether the financial and practical risk of getting that particular screen wrong is worth taking.
When Should a Shower Screen Be Measured?
Preliminary measurements are useful during planning, but final product selection and bespoke manufacture must reflect the completed surfaces.
Check the finished opening
Early dimensions can identify a likely product, but final suitability should be checked against:
- The completed tiled or panelled opening
- The exact manufacturer adjustment range
- Wall plumb at several heights
- Door movement and available clearance
- Tray, bath or shower-floor alignment
A product selected from the tray size alone may not suit the finished room.
Survey after the surfaces are complete
Final bespoke measurements should normally be taken after:
- The tray or bath is permanently installed
- Wall tiles or panels are finished
- Grouting is complete
- Half walls are complete
- Sloping ceilings and finished edges are formed
- The opening will no longer change
Which Shower Screen Finishes Are Available?
Standard products normally offer a smaller selection. Bespoke glass can provide access to a much wider range of channels, clamps, hinges, handles and support components.
Classic finishes
Polished chrome, satin chrome, brushed nickel, polished nickel, brushed stainless and polished stainless.
Dark finishes
Matte black, black, gunmetal, brushed gunmetal, polished gunmetal and oil-rubbed bronze.
Warm metallic finishes
Satin brass, polished brass, antique brass, brushed bronze, antique bronze, gold bronze and ultra-brass finishes.
Copper and pale finishes
Brushed copper, polished copper, antique copper, rose gold, matte white, white and warm-sunset-style finishes.
Confirm every component before choosing the final finish
Availability varies by component, manufacturer and fixing system. A hinge, channel, handle and support arm may not all be available in an identical specialist finish.
It is usually best to agree the glass arrangement first and then confirm which matching finishes are available across the complete package.
How Long Does Shower Screen Installation Take?
These are practical guide times rather than fixed promises. Product complexity, access, drilling surfaces and the condition of the bathroom can all affect the installation.
When can the shower be used?
Normal shower use should usually wait approximately 24 hours after the final silicone has been applied, unless the selected sealant or product instructions specify a different curing period.
What Should Be Ready Before Shower Screen Installation?
A clear, completed room protects the bathroom and gives the installer space to handle, position, drill and seal the glass properly.
The bathroom should ideally be:
- Tiled or panelled
- Fully grouted
- Clear of tools and building materials
- Dry enough for drilling and sealing
- Accessible through the property
- Free from other active trades in the room
- Complete enough that the opening will not change
- Ready for the glass to be safely handled
The product should ideally be:
- Safely stored on site
- The correct manufacturer and model
- The correct size and handing
- Free from visible damage
- Complete with profiles and seals
- Complete with handles, rollers or hinges
- Checked against the order where possible
- Accompanied by the installation instructions
SSI can unbox and inspect the supplied product on arrival. However, if the screen is damaged, incomplete or unsuitable for the finished opening, the planned work may not be able to continue and additional attendance may be chargeable.
What Is the Best Way to Clean Shower Glass?
Regular light cleaning is normally easier and safer than allowing limescale and soap deposits to build up.
After normal use
Use a shower squeegee to remove water from the main glass surfaces. This is one of the simplest ways to reduce water marks and limescale.
Regular cleaning
We commonly use Method Glass Cleaner for day-to-day cleaning and Sprayway Glass Cleaner for a more thorough weekly clean where available.
Use a soft cloth
Use a clean, non-abrasive cloth and avoid harsh pads, metal scrapers and aggressive chemicals on glass coatings or coloured hardware.
Check the manufacturer’s care instructions
Easy-clean glass coatings and specialist coloured finishes may have specific care requirements. Keep seals and channels clean and arrange an adjustment if a door, hinge or roller begins to move rather than forcing it.

Shower screen replacementShower Screen Advice FAQs
Should I buy the shower screen before contacting SSI?
Not necessarily. Sending photographs, approximate measurements and a link to the proposed product before ordering can help identify obvious sizing, adjustment, door-clearance or access concerns.
Is the tray size the same as the finished shower opening?
Not always. Tiles, adhesive, wall boards and the position of the walls can reduce the usable opening. The finished dimension between the completed surfaces should be checked against the manufacturer’s adjustment range.
Should the opening be measured before or after tiling?
Preliminary measurements can be taken during planning, but final product suitability should reflect the completed tiled or panelled opening. Bespoke glass should normally be professionally surveyed after all relevant surfaces are complete.
Will a correctly installed shower enclosure be watertight?
A suitable manufactured enclosure should provide very good water containment when the bathroom is correctly built and the product is installed and sealed according to the manufacturer’s instructions. Water direction, drainage capacity, seals, levels and product design all contribute to the result.
Can a blocked drain make the shower screen appear to leak?
Yes. If the waste is blocked, partially restricted or unable to clear the shower’s flow rate, water can build up and pass over tracks, thresholds, seals or open edges. The drainage should be checked before assuming the screen itself is faulty.
Why is water going beyond my walk-in shower screen?
The panel may be too short for the spray pattern, the shower head may point towards the opening or the tray or floor may direct water towards the open end. A longer panel, return panel or revised shower position may improve water control.
Do I really need a shower-screen support arm?
SSI normally recommends supporting a fixed panel unless the complete glass design and fixing system are suitable without one. Some correctly specified bespoke panels up to approximately 900 mm can perform successfully without an arm, but this is not a universal rule.
Can a support arm be fitted later?
Often, yes. A suitable support arm may be retrofitted if movement becomes a concern, although the fixing positions, glass arrangement and available components must first be checked.
Can I install a shower screen myself?
A technically capable person can achieve a good result when the product is manageable, the opening is suitable and the manufacturer’s instructions are followed precisely. Professional fitting becomes more valuable as the glass becomes larger, heavier, more expensive or technically involved.
How do I check whether the shower door will hit the toilet or basin?
Check the technical drawing for the door radius or projection and mark the movement on the bathroom floor. Allow practical clearance for the handle and for someone to enter and leave the shower comfortably.
What happens if the glass is too large to reach the bathroom?
Toughened glass cannot be cut or reduced after manufacture. The complete access route should therefore be checked before a large standard or bespoke panel is ordered.
How long should I wait before using the shower?
Normal shower use should usually wait approximately 24 hours after final silicone application. The selected sealant or product manufacturer may specify a different curing period.
Which shower-screen finishes are available?
Common finishes include polished chrome, brushed nickel, satin brass, matte black and gunmetal. Bespoke hardware can provide access to many additional metallic, antique, copper and coloured finishes, subject to the chosen component system.
What is the best way to clean shower glass?
Using a squeegee after showering is an excellent starting point. Use a suitable glass cleaner and soft non-abrasive cloth for routine cleaning, and follow any specific care guidance for coated glass or specialist hardware finishes.
Still Unsure Which Shower Screen Will Work?
