Tell Us Where Your Loft Conversion Has Reached

Final manufacturing dimensions wait until the controlling surfaces are complete, but useful glass advice can begin much earlier.

01

Planning or drawing stage

Send architect’s plans, bathroom elevations or a sketch. SSI can identify the likely glass route, approximate complexity and information needed later.

02

Conversion under construction

SSI can coordinate likely hinge, channel and support positions with the builder or bathroom contractor before the walls are closed and tiled.

03

Bathroom ready to measure

Once the tray or floor, tiles, roofline and other glass-controlling surfaces are complete, the professional manufacturing survey can take place.

Early contact does not commit you to bespoke glass

SSI will first check whether a suitable manufactured or reduced-height product can fit the planned opening before exploring shaped or fully bespoke glass.

SSI Works with the Team Building Your Loft Bathroom

Loft companies, builders, architects, designers, bathroom fitters and tilers are all welcome to contact SSI directly. This avoids technical glass information being passed through the homeowner second-hand.

The wider project team remains responsible for the room layout, plumbing, waterproofing, shower location, usable headroom and structural work. SSI advises on the shower-glass configuration, likely fixing positions, final measurement, manufacture and installation.

SSI can help the project team with

  • Reviewing drawings, elevations and proposed openings
  • Checking whether a standard product is likely to fit
  • Identifying likely door, panel and support positions
  • Suggesting strategic structural fixing locations before tiling
  • Planning the final survey and manufacturing information
  • Supplying and installing the agreed shower-glass package

Loft, Attic, Dormer and Room-in-the-Roof Bathrooms

The page covers loft conversions, attic conversions, dormer ensuites, roof-space bathrooms, room-in-the-roof bathrooms and converted upper-floor shower rooms beneath eaves.

The best glass route depends on the finished opening—not simply the fact that the bathroom is in a loft. Straight dormer walls may accept a manufactured product, while eaves and rooflines may require shaped glass.

Strategic Fixing Positions Can Be Considered Before Tiling

Where the likely door, channel or support position is reasonably clear, SSI can suggest locations where the contractor may wish to provide timber or another suitable structural fixing zone.

The builder remains responsible for designing, providing and confirming the structure. SSI’s input is glass-specific: it helps the project team avoid completing a beautifully tiled wall without a dependable fixing where a heavy hinge or support later needs to sit.

  • Likely wall-hinge position
  • Wall and ceiling channel lines
  • Support-arm or brace position
  • Fixed-panel restraint
  • Potential glass-to-glass hinge loading

Planning dimensions versus manufacturing dimensions

When Is a Loft Shower Ready for Its Final Glass Survey?

Plans and approximate dimensions are valuable early, but toughened glass must be manufactured from the finished opening.

1

Tray or floor complete

The final glass line and base level must be fixed.

2

Tiles complete

Finished wall thickness can materially change the opening.

3

Roofline finished

Slopes, apexes, ceilings, beams and boxed sections must be final.

4

Half walls complete

Any tiled upstand controlling glass position or shape must be ready.

5

Opening confirmed

Door position, fixed panels and access route should be agreed.

Final decorative silicone is not always required before measuring

Survey can normally proceed once every surface controlling the glass dimensions is complete, stable and unlikely to change.

Check the route before ordering

The Glass Must Reach the Loft Bathroom as Well as Fit It

Roof-space bathrooms often have the most restricted carrying routes in the property. A large panel may fit the shower perfectly but still be impossible to turn on the staircase or stand upright in the room.

Access is reviewed before manufacture. Where one large panel is impractical, the arrangement can sometimes be redesigned as two or more connected sections.

Loft glass access checklist

  • Front door and hallway
  • Main staircase and winder turns
  • Low stairwell or landing ceiling
  • New loft staircase and balustrades
  • Landing turns and restricted corridors
  • Bathroom doorway
  • Space to rotate and stand the panel upright
  • Protection of shaped corners and narrow points
Flexible supply and installation

Customer-Supplied, SSI-Supplied or Fully Managed Glass

How SSI becomes involved depends on what has already been selected and how specialised the finished opening is.

01

Customer-supplied product

SSI can install a suitable manufactured screen or enclosure after reviewing the product, opening, adjustment range, access and supplied components.

02

Standard supply and installation

SSI can recommend and supply a suitable manufactured product where one fits the completed loft or dormer opening properly.

03

Custom glass package

Where shaped or connected glass is required, SSI can manage the concept, survey, CAD, manufacture, installation, sealing and handover.

A staged route from plans to installation

How a Loft or Attic Shower-Glass Project Progresses

The process stays proportionate: simple manufactured products do not need the same route as individually shaped glass.

1

Send the project information

Share plans or photographs, project stage, approximate dimensions, intended opening and postcode.

2

Identify the likely glass route

SSI checks standard, reduced-height, made-to-measure, shaped and complete bespoke options.

3

Coordinate before finishes

Where useful, SSI speaks directly with the project team about likely fixing positions and final survey requirements.

4

Survey the finished opening

For custom work, the professional survey is normally approximately £120–£150 once the controlling surfaces are complete.

5

Approve and manufacture

The final CAD records the agreed configuration and is approved before the toughened glass is produced.

6

Install and hand over

SSI installs the agreed package, checks operation and support, explains cure times and completes customer sign-off.

Early review

Plans and approximate sizes

Useful for configuration advice, feasibility, coordination and an approximate budget. They are not used to manufacture the final glass.

Professional survey

Finished manufacturing dimensions

For custom work, SSI digitally measures the completed opening and prepares the final CAD manufacturing information.

Managed package

Clear glass responsibility

Where SSI surveys, supplies and installs, SSI accepts responsibility for the agreed shower-glass package within the confirmed scope.

Loft conversion questions

Frequently Asked Questions

These answers help customers involve SSI at the right stage and identify the correct shower-glass route.

When should I contact SSI about a loft shower screen?

You can contact SSI during planning, while the conversion is being built or once the bathroom is finished. Early contact allows likely glass routes and fixing positions to be considered, while final manufacturing measurement waits until the controlling surfaces are complete.

Can SSI work from architect’s plans?

Yes. Plans, elevations, sketches and approximate dimensions can be reviewed to identify the likely glass configuration and approximate complexity. They are not treated as final manufacturing dimensions.

Will SSI speak directly with my builder or bathroom fitter?

Yes. SSI welcomes coordination with loft companies, builders, architects, designers, bathroom fitters and tilers where direct communication helps the project.

Can SSI advise where structural support may be needed?

SSI can suggest likely strategic fixing positions for hinges, channel and support components before tiling. The builder or relevant contractor remains responsible for designing, providing and confirming the structure.

Does every loft shower need bespoke glass?

No. SSI first checks whether a suitable manufactured, reduced-height or simple made-to-measure product can fit. Shaped or full bespoke glass is recommended only where the finished opening requires it.

Can a standard shower enclosure fit in a dormer?

Often yes, where the dormer provides straight walls, sufficient height, a suitable finished width and practical door movement. The product must still remain within its published adjustment and installation conditions.

What information should I send first?

Send the project stage, plans or a front-on photograph, approximate opening dimensions, the intended door or screen position and the postcode. For a sloping opening, include the approximate highest and lowest points.

When can the final glass survey take place?

After the tray or finished floor, wall tiles, roofline, ceiling, half walls and other surfaces controlling the glass dimensions are complete and will not change.

How much is the professional survey?

For custom glass, the professional survey is normally approximately £120–£150 and includes travel, accurate measurement, laser assessment, final CAD information and recommended glass and components. It is non-committal.

Can SSI supply the shower screen as well as install it?

Yes. SSI can recommend and supply suitable manufactured products or manage custom glass from initial concept through survey, manufacture and installation.

Can SSI install a screen I have already bought?

Yes, where the product is suitable for the finished opening and its components, adjustment range, fixing surfaces and access have been checked.

What if the glass will not fit up the loft stairs?

Access is checked before manufacture. A large panel may sometimes be redesigned as several connected sections if the staircase, landing, doorway or available rotation space makes one sheet impractical.

Is this page also for attic and roof-space bathrooms?

Yes. It covers loft conversions, attic conversions, dormer ensuites, roof-space bathrooms, room-in-the-roof bathrooms and converted upper-floor shower rooms beneath eaves.

Where can I read about angled or apex-shaped glass?

The Sloping Ceiling Shower Screens page explains shaped fixed panels, angled doors, apex arrangements, measuring methods, templates and support in greater detail.

Where can I read about a flat but low ceiling?

The Reduced Height Shower Screens page covers shorter rectangular doors and panels for flat low ceilings, beams, bulkheads, basements and other restricted-height openings.

Does this service include bath screens beneath roof slopes?

No. Bath-screen projects are kept separate so that this page remains focused on shower trays, wet-room areas and shower enclosures within loft and attic conversions.
