Plan the connections around the panel
Choose ABA panel joints and trims
The panel face is only part of the wall. Joining profiles, corners and exposed edges shape the finished appearance and determine what the installation team needs at each junction.
Start with a wall elevation
Mark the connections before turning a decorative range into an accessory order.
Draw the panel positions, internal and external corners, exposed ends, openings and transitions to other finishes. In a bathroom, add the tray or bath, fittings, niches and every penetration. Each location needs a defined detail, even when the aim is a visually continuous wall.
Choose whether a joining line should be expressed, recessed or handled by the selected panel’s machined edge. This connects the desired appearance to the actual product: a trim-based joint and a tongue-and-groove connection are different routes, with different installation details.
Match each location to a profile
The catalogue accessory programme lists anodized aluminium profiles, generally identified as 2800 × 8 mm, plus a separate mounting plate.
| Wall condition | Listed accessory direction | What the detail needs to resolve |
|---|---|---|
| A line between panels | I-shaped and alternative joining trims | The intended visible line, engagement with the panel edge and installation sequence. |
| A recessed joining line | Recessed T trim | The recess appearance, panel seating and actual clearance in the profile. |
| An internal corner | Inner corner trim | How both wall faces terminate and how the corner is sealed where required. |
| An external corner | Outer corner trim | The exposed edge, alignment and protection at the turn. |
| A visible panel termination | End trim | The cut edge and transition to the adjacent surface or opening. |
| A planned lighting channel | LED groove trim | The channel and adjacent panels, with lighting components specified separately. |
| The selected fixing arrangement | 50 × 50 mm stainless-steel mounting plate | The applicable fixing method and installation layout; the plate dimensions are not a load rating. |
Distinguish butt joints from tongue and groove
A connection name should lead to an actual detail rather than an assumption about sealing.
A butt joint brings panel edges together without a tongue engaging a groove. Its finished treatment may use an appropriate joining profile or another detail permitted by that system. The desired visual line does not itself specify the material or method used to manage water at the connection.
A tongue-and-groove panel has complementary machined edges. The supplied profile, fitting sequence and any required sealant remain part of the installation. The wider catalogue mentions groove locking with metal trims or T&G click, without assigning one universal connection to every size and finish.
Configuration-specific documentation reports no leakage after a 24-hour test of its particular T&G joint under a manufacturer protocol verified by an independent laboratory. That result belongs to the tested assembly; it does not qualify a different butt joint, every trim or all corners in a shower.
Read the documented joint-test scopeFit the accessory to the selected thickness
The 8 mm accessory notation is useful range information, not compatibility with every board.
The broader panel programme includes thicknesses from 6 to 12 mm. Its commonly listed 2800 × 8 mm trims must be checked against the exact finished panel and edge. A profile intended around an 8 mm board cannot simply be treated as a universal fitting for that whole range.
Use the current panel and profile drawings together. Check the receiving slot, engagement depth, face position and clearance, then trial the actual pieces. A product’s shorthand size does not describe every dimension of its cross-section.
Finish selection matters too. Several joining, corner, end and LED-groove options list matt or glossy finishes; the recessed T and one alternative joining profile are listed as matt. Build the accessory schedule from the chosen profiles and finish samples rather than assuming that every trim shares every colour or finish.
Select the panel format firstKeep wet details and lighting in the wall brief
A complete accessory schedule is easier to quote, fit and replace.
For a shower, carry the joint decision through corners, cut edges, tray or bath connections and penetrations. List the compatible adhesive and sealant with their installation instructions. A decorative metal profile does not, by its presence alone, establish a waterproof junction.
An LED-groove trim provides a channel direction in the accessory range. The light source, wiring and electrical suitability for the location are separate specifications; the trim listing is not certification of a complete lighting system.
Finish the brief with the profile type, quantity, lengths, finish, panel thickness and the detail where each is used. Retain a joined sample and the selected accessory references for future replacements.

Make the connection specific to the board and the location.
Do all ABA wall panels use the same trims?
No. Thickness, edge machining, finish and the selected joining system affect compatibility. The catalogue’s 8 mm accessory notation does not establish a fit for every 6–12 mm panel. Use matching drawings and an actual panel-and-profile sample.
Does a tongue-and-groove joint remove the need for sealant?
Follow the selected system’s written wet-area details. A machined connection or a laboratory joint result does not establish that every installation can omit sealant, including at corners, penetrations and the tray or bath.
Can a continuous pattern hide the panel joints?
A planned image can continue visually across designated panels, but the physical connection still needs its own detail. Match the decorative sequence and the joint independently so that cutting, orientation and sealing remain workable.
