Choosing the right sliding shower door is not simply a case of matching the number on the shower tray. The finished opening, installation style, adjustment range and whether you are using a side panel all affect the configuration you need.
The Momentum sliding shower enclosure is particularly versatile because the same clean, frameless-style system can be used in three very different ways: wall to wall in a recess, as a freestanding open-ended shower, or with a side panel to create a complete corner enclosure.
To make choosing the correct combination easier, use our shower enclosure size calculator below. Select your finish and installation type, enter your measurement and the calculator will identify the appropriate configuration.
Find the right Momentum shower door size
Choose your finish, tell us how the enclosure will be installed and enter your finished measurement. If you are creating a corner enclosure, simply select the required side panel depth as well.
Important: measure the finished bathroom after tiling wherever possible. Do not rely purely on the nominal size of the shower tray.

Momentum
One sliding shower door, three installation options
One of the most useful features of the Momentum design is its hybrid installation system. Rather than having completely separate products for a recess, an open-ended shower and a corner enclosure, the system can be configured to suit the layout of the bathroom.
This gives you far more freedom when planning a new bathroom and can be particularly useful when working with large rectangular shower trays, wetroom floors or spaces where the shower position does not fit a conventional enclosure layout.
1. Wall-to-wall installation
For a shower positioned inside a recess, the sliding door can span between two finished walls. This creates a clean recessed enclosure without requiring a side panel.
It is an excellent option where the architecture of the room already forms the two sides of the shower.
2. Freestanding open-ended installation
The enclosure can also be installed with an open end, giving the shower a lighter, more walk-in appearance while retaining the practicality of a sliding door.
This works particularly well with larger shower trays and contemporary wetroom-style bathrooms.
3. Door with side panel
Add a matching side panel and the same sliding door becomes a complete corner shower enclosure.
Side panels are available to suit common tray depths, making this a flexible option where the shower sits in the corner of the bathroom.
Why the hybrid design is so useful
Bathroom layouts rarely follow one standard formula. Some homes have a natural recess, some have enough room for an open-ended wetroom arrangement and others need a traditional enclosed corner shower.
The Momentum system can adapt to all three situations while maintaining the same minimalist appearance. That flexibility is particularly useful when planning a bathroom before every final dimension has been confirmed.
It can also simplify the design process. Instead of choosing between completely different styles of shower enclosure, you can choose the installation configuration that works with the room while keeping the same sliding-door appearance.
A frameless look without sacrificing practicality
Large areas of clear glass and minimal framing give the enclosure its distinctive contemporary appearance. The emphasis is on the glass rather than heavy surrounding profiles, helping the shower area feel open and spacious.
The door uses 8mm toughened safety glass and stands 2000mm high, giving it the proportions expected from a modern premium shower enclosure.
A fixed glass section works alongside the sliding door, allowing the entrance to open without a door swinging out into the bathroom. This makes a sliding enclosure particularly useful where there is a vanity unit, WC, radiator or other furniture close to the shower.
Which Momentum shower door size do I need?
The range is available in nominal front sizes of:
- 1000mm
- 1100mm
- 1200mm
- 1400mm
- 1500mm
- 1600mm
- 1700mm
However, the number in the product name is not necessarily the exact finished wall-to-wall measurement required for installation. Shower enclosure profiles provide an adjustment range, which is why measuring the actual finished opening is so important.
Rather than trying to work backwards from a nominal size, enter your real measurement into the calculator above. It will compare your measurement with the available adjustment ranges and identify the appropriate configuration.
How to measure for a wall-to-wall sliding shower door
For a recessed installation, measure the finished opening after the walls have been tiled wherever possible.
- Measure from finished wall to finished wall near the bottom of the enclosure.
- Take another measurement around the middle.
- Measure again towards the top.
- Do not assume that the walls are perfectly parallel.
- Enter the relevant finished measurement into the calculator to check the suitable enclosure range.
The available adjustment can compensate for a degree of variation in the walls, but accurate measurements are still essential. The shower tray or wetroom floor must also be correctly prepared and level before installation.
How to size a shower door with a side panel
For a corner enclosure you need to consider two dimensions: the front width and the return depth.
The front measurement determines the sliding-door configuration, while the depth determines the side panel. Available side panel sizes include 700mm, 760mm, 800mm and 900mm.
Select With side panel in the calculator, enter the tray or shower-area width and then choose the appropriate side panel depth. The calculator takes the different installation arrangement into account when identifying the door configuration.
Six finishes for very different bathroom styles
The minimal glass design means the finish of the profiles and hardware becomes an important part of the overall bathroom scheme. There are six options:
- Chrome – bright, clean and easy to coordinate with almost any bathroom.
- Matt Black – strong contrast for contemporary monochrome and industrial-style bathrooms.
- Brushed Brass – a warmer finish that works particularly well with marble, stone and neutral interiors.
- Brushed Bronze – softer and slightly deeper in tone for warm, design-led bathrooms.
- Gun Metal – a darker metallic option that pairs well with grey, stone and dramatic tile schemes.
- Brushed Nickel – a softer metallic alternative to polished chrome with a more understated appearance.
Matching the enclosure finish with your shower controls, shower head, taps and bathroom accessories can give the whole room a much more considered appearance.
Reversible sliding door installation
The sliding door is reversible, allowing it to be configured for either left-hand or right-hand opening.
This is useful because the most convenient opening direction often becomes obvious only once the full bathroom layout has been planned. Consider the position of the basin, WC, towel rail, bathroom door and the direction you naturally approach the shower.
Because a sliding door stays within the footprint of the enclosure, there is no outward door swing to accommodate.
One important installation detail: check the support arm position
The main detail worth planning carefully before installation is the position of the enclosure support arm in relation to your shower fittings.
Check where the support arm will sit before fixing the shower head or shower arm. Depending on the layout, the two can potentially compete for the same area of wall space.
A few minutes spent planning their positions before drilling tiles can avoid having to move a shower head or alter the enclosure installation later.
Suitable for shower trays and wetroom-style installations
The enclosure can be used with a suitable shower tray or as part of a tiled wetroom-style installation, making it useful for both conventional bathrooms and more open contemporary shower spaces.
If you are using a shower tray, make sure the usable enclosure dimensions correspond with the tray and the intended installation position rather than simply assuming that two products carrying the same nominal dimension will automatically fit together.

Why choose a sliding shower door?
Sliding shower doors are especially useful where bathroom floor space is limited because the door does not need to swing into the room.
They are equally effective in larger bathrooms, particularly when paired with long rectangular trays. The long horizontal proportions of the enclosure can create a spacious walk-in appearance while still providing a proper sliding entrance.
The Momentum system combines that space-saving operation with a minimal frameless-style appearance and the flexibility to change the overall enclosure format depending on your room.

Easy-clean glass and everyday maintenance
The glass has an easy-clean surface treatment designed to reduce the ability of water deposits, soap residue and limescale to adhere to the glass.
That does not make any shower enclosure completely maintenance-free. Regular rinsing and using a squeegee after showering will help keep clear glass looking its best.
Avoid abrasive cleaners and rough cleaning materials on the glass or finished metalwork. Gentle, regular cleaning is considerably better than allowing heavy limescale deposits to build up.

Frequently asked questions
What size Momentum shower door do I need?
Measure the finished shower opening rather than choosing purely from the nominal tray size. Enter the measurement and installation type into the calculator above to find the appropriate configuration.
Can the Momentum sliding shower door be fitted wall to wall?
Yes. It can be installed across a recessed opening between two finished walls, without requiring a side panel.
Can it be used as a freestanding shower enclosure?
Yes. An open-ended configuration can be used where the layout does not require a second enclosing side panel, giving the shower a more open wetroom-style appearance.
Can I add a side panel?
Yes. A side panel can be added to create a complete corner enclosure. Common side panel sizes include 700mm, 760mm, 800mm and 900mm.
Can the sliding door open from either side?
Yes. The enclosure is reversible, allowing the sliding door to be configured for left or right-hand opening during installation.
Is a sliding shower door suitable for a small bathroom?
A sliding door can be particularly useful in smaller bathrooms because it does not require the floor clearance needed for an outward-opening hinged or pivot door.
Can it be installed directly onto a wetroom floor?
Yes. The system can be used with an appropriate shower tray or a correctly prepared tiled wetroom-style floor.
What should I check before installation?
Check the finished opening measurements, ensure the tray or floor is level, decide which direction the door should open and plan the position of the support arm before installing the shower head or other wall-mounted fittings.
