Made to Measure Changes the Dimensions

A made-to-measure screen keeps a familiar rectangular glass configuration but changes its width, height or both so it fits the completed bathroom properly.

This is useful where a standard product nearly works but its adjustment range, height, glass width or overall proportions do not suit the finished space. The result may be a fixed panel, a full-height panel, a rectangular door or a simple door with one fixed inline panel.

Made to measure normally means

  • Predominantly rectangular shower glass
  • An exact custom width, height or both
  • A straightforward fixed panel or moving door
  • Known channels, clamps, hinges and seals
  • No roof slopes, notches or complex shaped edges
  • A shorter and simpler route than a complete bespoke design

Made to measure changes the dimensions. Bespoke changes the complete design.

Angled tops, half walls, notches, apexes, several connected panels and architecture-led configurations remain on the Bespoke Shower Screens or Sloping Ceiling Shower Screens pages.

Use the simplest route that fits properly

Standard, Made to Measure or Fully Bespoke?

Custom glass is valuable when it solves a real dimensional problem. It is not automatically better than a suitable manufactured screen.

Standard manufactured screen

Best where the available size, adjustment range, support system, finish and configuration work correctly in the completed bathroom.

First check: SSI can review suitable off-the-shelf options before custom glass is ordered.

Made-to-measure glass

Best where a straightforward rectangular panel or door needs an exact width or height that is not available as a suitable standard product.

Main change: the dimensions.

Fully bespoke arrangement

Best for shaped glass, complex connected panels, unusual door loading, half walls, slopes, specialist support or architectural detailing.

Main change: the complete configuration.

What Can Be Made to Measure?

The page focuses on rectangular glass that follows a familiar installation route but needs dimensions unavailable from a standard product range.

01

Exact-width fixed panels

A rectangular screen manufactured to the width needed for a tray, wet-room floor, half opening or defined glass line.

02

Exact-height panels

A standard-style fixed panel made taller or shorter to suit a finished flat ceiling, visual line or project requirement.

03

Full-height glass

Rectangular glass extending to the ceiling, with wall, floor and top restraint designed around the completed room.

04

Rectangular shower doors

A door manufactured for a completed aperture where an available standard door cannot provide the required fit or appearance.

05

Door with one inline panel

A simple rectangular door and fixed inline panel may remain made to measure where there are no shaped edges or unusual support conditions.

06

Custom walk-in panels

A rectangular open-shower panel manufactured to a chosen size after panel length, access, support and spray control have been considered.

The most important measurement distinction

The Finished Opening Is Not Automatically the Glass Size

A finished opening might measure 900mm, but the manufactured glass may need to be smaller. Hinges, U-channel, clamps, seals, door movement and installation clearance all require planned deductions.

Those deductions are specific to the selected hardware and configuration. Ordering a glass sheet at exactly the same dimension as the opening can make it impossible to install or operate safely.

Opening measurement

The completed distance between the finished walls, tray, floor or ceiling surfaces.

Manufacturing measurement

The actual glass dimensions after hardware deductions, operating gaps and installation tolerances are applied.

Precision includes clearance

An Exact Fit Does Not Mean Zero Gap

Toughened glass must be protected from hard contact with tiles, stone and surrounding finishes. The correct result uses small designed tolerances appropriate to the channels, clamps, hinges and seals.

This allows the glass to be installed, aligned and operated without treating the finished building as though it were a perfectly machined opening.

Designed tolerance can allow for
  • Channel or clamp engagement
  • Hinge and closing gaps
  • Bottom sweeps and thresholds
  • Minor wall or floor variation
  • Safe glass handling and installation
Preliminary sizes first, manufacturing sizes later

Final Glass Is Measured from Completed Surfaces

Approximate dimensions are useful for assessing the route and pricing. Final manufacturing dimensions depend on the completed surfaces that define the glass opening.

1

Send photographs

Include the full shower area, likely panel or door position, approximate width and height, project stage and postcode.

2

Check the route

SSI checks whether a suitable manufactured product may work before recommending custom glass.

3

Confirm finished surfaces

Tray or floor, wall tiles or panels, grouting, ceiling line and the final glass position must be fixed before professional measurement.

4

Specify the glass

Glass dimensions, thickness, machining, hardware, clearances and support are confirmed together before manufacture.

Professional survey or confirmed third-party sizes

A professional SSI survey is normally approximately £120–£150. Where a customer or experienced third party supplies confirmed manufacturing information, SSI can source the glass without carrying out its own survey, but responsibility for those dimensions remains with the person who supplied them.

Glass and hardware form one specification

8mm, 10mm or 12mm Toughened Glass

The correct thickness depends on the glass dimensions, whether it moves, the hinge or clamp system, support and the overall installation—not on a simple assumption that thicker is always better.

8mm glass

Useful for selected moving doors and panels where lower weight reduces loading on hinges, supporting glass and wall fixings.

10mm glass

A common substantial specification for rectangular fixed panels, doors and simple made-to-measure arrangements.

12mm glass

Reserved for selected larger, specification-led fixed panels where the size, support and compatible hardware justify the additional weight.

Holes and machining must be decided before toughening

Hinge cut-outs, handle holes, clamp positions and other machining are completed before the glass is toughened. The finished panel cannot later be drilled, trimmed, shortened or altered on site.

Hardware Compatibility Matters as Much as Size

A panel can have the correct width and height and still be unusable if its glass thickness, holes or edge clearances do not match the chosen fittings.

  • Hinges must suit the glass thickness, width and weight
  • U-channel must accept the selected glass and fitting method
  • Clamps need suitable edge distances and fixing surfaces
  • Door sweeps and seals need the correct operating gaps
  • Thresholds and water bars must relate to the finished floor or tray
  • Support must be planned around the exposed glass edge

Glass should not be ordered first with the expectation that suitable hardware can always be selected afterwards.

Choose the right responsibility level

White-Glove, Confirmed Dimensions or Installation-Only

SSI can take responsibility for the complete agreed glass package or work from suitable measurements and products supplied by others. The service route determines who is responsible for fit.

Full service

White-glove survey, supply and installation

SSI assesses the project, surveys the finished opening, specifies and sources the glass and components, installs the agreed package and completes the handover.

Confirmed sizes

Glass sourced from supplied dimensions

SSI can source straightforward rectangular glass from confirmed customer or third-party sizes. The party supplying those dimensions remains responsible for their accuracy.

Fitting service

Installation-only

SSI can install suitable customer-supplied made-to-measure glass after reviewing the drawing, dimensions, hardware, fixing conditions, access and product condition.

If customer-supplied glass does not fit

Toughened glass cannot be corrected on site. SSI will explain any mismatch or missing component before continuing. Alternative parts, replacement glass or return attendance may be chargeable and are handled reasonably case by case.

A faster custom-glass route

Typical Lead Time: Around 10 Days to Two Weeks

Straightforward rectangular panels and doors are commonly available around 10 days to two weeks after the final survey or supplied dimensions have been confirmed.

The guide normally assumes

  • A straightforward rectangular panel or door
  • Clear, approved dimensions
  • Standard glass and edge finishing
  • Available compatible hardware
  • No shaped machining or specialist fabrication

Lead time may change with

  • Complex hinge or handle machining
  • 12mm or specialist glass requirements
  • Non-standard hardware finishes
  • Supplier capacity and delivery schedules
  • Changes after dimensions are confirmed

Pricing is provided on assessment

Cost depends on size, thickness, machining, components, survey route, access and installation complexity. Send the shower area for an initial assessment.

Simple shape, professional handling

Access, Installation and Handover

A rectangular panel can still be large, heavy and difficult to rotate through a staircase, landing or bathroom doorway. Access is checked before manufacture where SSI is managing the glass package.

1

Review access

Check entrances, turns, stairs, landings, doorways, ceiling height and space to stand the glass upright.

2

Protect and position

SSI normally uses two installers for glass handling, accurate placement and protection of the completed bathroom.

3

Fix and align

Channels, clamps, hinges, seals and supports are installed and adjusted according to the agreed glass and hardware specification.

4

Seal and hand over

The customer can inspect the glass and operation, with cleaning, cure-time and use guidance provided before sign-off.

Silicone cure guidance

Where channels, fixed joints or thresholds are sealed, allow 24 hours before using the shower unless the sealant or component manufacturer states otherwise.

Frequently Asked Questions

Answers about exact dimensions, glass sizes, surveys, customer measurements, lead times and installation.

What is a made-to-measure shower screen?

It is normally a straightforward rectangular fixed panel or shower door manufactured to a custom width, height or both for a completed bathroom.

What is the difference between made to measure and bespoke?

Made to measure normally changes the dimensions of a familiar rectangular arrangement. Bespoke changes the complete design and may include shapes, notches, half walls, several connected panels or specialist support.

Will SSI check standard screens first?

Yes. A suitable manufactured product may provide good adjustment, tested components and better value. Custom glass is recommended where a standard screen cannot achieve the required fit or appearance.

Can a fixed panel be made to an exact width?

Yes. Rectangular fixed panels can be manufactured to a chosen width after the finished opening, support, glass thickness and required installation tolerances have been established.

Can a shower panel be made to an exact height?

Yes. Rectangular panels can be made taller, shorter or full height, subject to access, support, ceiling conditions and the intended shower layout.

Can a rectangular shower door be made to measure?

Yes. The door width, height, glass thickness, hinges, handle machining, seals, threshold and opening clearances must be specified together.

Can a door and one inline panel count as made to measure?

Yes, where both pieces are straightforward rectangular glass and there are no shaped edges, half walls or unusual support conditions. More complex configurations move to the Bespoke route.

Is the finished opening measurement the same as the glass size?

Not necessarily. The glass normally needs deductions for channel, clamps, hinges, seals, door movement and installation clearance. The deductions depend on the selected hardware and configuration.

Why can the glass not be made as a completely tight fit?

Toughened glass needs controlled clearances so it can be installed without hard contact against tiles or stone and so moving doors, seals and fittings can operate correctly.

When should final measurements be taken?

After the tray or floor, wall tiles or panels, grouting, ceiling and every surface defining the glass position are completed and fixed.

How much is a professional survey?

A professional survey is normally approximately £120–£150 and includes travel, accurate measurement, laser assessment and the glass and component information required for the agreed route.

Can SSI source glass from measurements I provide?

Yes, where the dimensions and hardware information are sufficiently clear. The person supplying the dimensions remains responsible for their accuracy and for the resulting fit.

Can SSI install made-to-measure glass supplied by someone else?

Yes. SSI will ideally review the manufacturing drawing, glass dimensions and thickness, hardware, fixing conditions, access and product condition before booking.

What glass thickness is used?

8mm, 10mm or 12mm toughened glass may be used according to the panel size, moving weight, hinge or clamp capacity, support and overall specification.

Can toughened glass be adjusted after manufacture?

No. It cannot be cut, drilled, shortened or re-shaped on site. All holes, hinge cut-outs and machining must be correct before the glass is toughened.

How long does made-to-measure glass take?

Straightforward rectangular panels and doors are commonly available around 10 days to two weeks after the final survey or confirmed dimensions. Specialist glass, hardware or finishes may take longer.

How much does a made-to-measure shower screen cost?

Pricing is provided on assessment because it depends on glass size and thickness, machining, hardware, survey route, access and installation complexity.

How soon can the shower be used after fitting?

Where channels, fixed joints or thresholds are sealed, allow 24 hours before showering unless the sealant or component manufacturer states otherwise.
