Can This Shower Tray Be Cut? Verify the Boundary First
“Cuttable” sounds like a simple yes-or-no feature. In practice, it is a controlled installation condition.
A tray may be available in custom dimensions from the factory while site cutting remains prohibited. Another model may allow trimming only on selected sides. A third may require a specific blade, cut direction, edge treatment and support detail.
The material family does not answer the question. The exact model documentation does.
Start by separating three different offers
Factory-made custom size
The manufacturer supplies the finished dimensions. No site modification is implied.
Factory cut from a standard blank
The manufacturer cuts a standard tray before finishing and inspection. The cut is part of the supplied product.
Site adaptation
The installer modifies the delivered tray. This introduces tool control, dust, exposed-edge, support, drainage and warranty questions.
Acquabella's 2025 catalogue identifies bespoke-cut geometry for selected products. Duravit states that its Sustano tray made with DuroCast Nature can be shortened by up to 100 mm on each side. These examples are useful precisely because their permissions are product-specific. They do not create a rule for all composite trays.
The eight-point cut approval
1. Approved model and drawing revision
Record the complete model code and the drawing revision. Do not approve cutting from a generic range brochure.
2. Permitted cut zone
The marked-up drawing should show which edge can be cut, maximum material removal and the minimum remaining distance from the drain, rim, falls, reinforcement and enclosure landing zone.
3. Tool and blade
Define the approved tool, blade type, cutting speed or feed guidance, support method and dust-control requirement. “Use a saw” is not an installation procedure.
4. Cut direction and protection
Identify which face is cut from, how the finished surface is protected and how chipping or delamination is inspected.
5. Exposed-edge treatment
Confirm whether the edge must be sealed, coated, polished, capped or concealed. If no treatment is required, obtain that statement in writing for the exact construction.
6. Support after cutting
Cutting can change the perimeter bearing or underside support area. The installation drawing must show continuous support, bedding or framing after modification.
7. Enclosure and waterproofing interface
The new edge must still provide the required wall junction, seal path and enclosure landing width. Recheck the finished opening and profile adjustment after the cut.
8. Warranty boundary
State who is authorised to cut, what evidence must be retained and which failures remain covered. A site cut should not be approved through a sales chat that never reaches the installer.
Wakebath's current evidence boundary
Selected Wakebath textured trays are intended to support site adaptation, but the controlled procedure is still being completed. The permitted zones, drain and edge distances, tools, dust control, cut-edge decision, installation support and warranty boundary must be released before an installer relies on the claim.
There is currently no approved public statement that the tray can be “cut to any shape” or that an exposed cut edge requires no treatment. Those phrases should remain off the website until the procedure proves them.
Site record to retain
- Approved marked-up drawing
- Model and batch identification
- Before-cut photographs
- Tool and blade identification
- Cut dimensions
- Edge inspection photographs
- Applied edge treatment, if any
- Substrate/support photographs before closing
- Installer name and date
- Final drainage and leak check
This record turns a verbal promise into a traceable installation decision.
Primary references and evidence boundary
Evidence boundary. “Cuttable” is not a material-wide property or permission. It must be tied to a named model, approved zone, maximum removal, tool method, support detail, edge treatment and warranty position. A marketing page can identify that a capability exists; the current installation document and written supplier approval must control the actual site cut.
- BS EN 14527:2016+A1:2018 — Shower trays for domestic purposes. Its scope addresses shower-tray characteristics, cleanability, durability and conformity procedures when installed and maintained to manufacturer instructions. It does not grant permission to cut a product or define a universal cut zone.
- Duravit Sustano official product information. The page publishes a maximum shortening of 100 mm on each side for the named Sustano range. That limit belongs to this product family and cannot be applied to another DuroCast product or another manufacturer's composite tray.
- Acquabella 2025 general catalogue. Its technical section shows bespoke-cut geometry and model information. It demonstrates factory/product-specific customisation; the catalogue alone does not authorise an installer to improvise any cut on site.
Sources checked 6 September 2026. Obtain the current model installation manual and written cut approval before marking, cutting or altering support and waterproofing details.

A practical alternative: model-specific cut-to-size review
Need a tray adapted to the finished opening? Wakebath can review the proposed cut against the exact tray model, drain position, enclosure landing area and installation support. This is a model-specific engineering review—not a universal permission to cut.
What to send
- Exact tray SKU and drawing revision
- Finished opening and proposed cut line
- Drain direction and waste arrangement
- Enclosure model, landing area and wall build-up
- Planned substrate, support and edge treatment
Wakebath will return one of three decisions: approved under stated conditions, factory customisation recommended, or not enough evidence.
