Our shower trays featuring Acrystone® technology are cuttable. A substantial advantage that enhances versatility in design and installation, minimizes the risk of error and provides autonomy and efficiency to the professional. The great allies for flawless installations.
We tell you how to cut a resin shower tray.
Key points for cutting a shower tray
- Acrystone® allows on-site adaptation: Cuttable shower trays help installers overcome pillars, corners and irregular spaces without compromising the material’s integrity.
- Measurement must be precise: A spirit level and measuring tape are essential to avoid millimetric errors that could affect the installation.
- Use the right cutting tool: A speed-controlled angle grinder with a diamond disc for resin and mineral load helps achieve a clean and safe cut.
- Work continuously and safely: The cut should be smooth, without abrupt stops, and always with the correct protection measures.
Every bathroom project is unique and many of them require custom-designed equipment. And in many cases, beyond the need for made‑to‑measure materials, the possibility to adapt them on‑site offers the professional an added advantage.
We are committed to the challenge of achieving ever more agile and comfortable installations and our purpose is that professional installers achieve perfect results in any bathroom project by offering efficient solutions. That is why we develop materials that allow overcoming pillars, corners or angles thanks to their ability to be cut on‑site.
This is the case with the solutions we manufacture using our Acrystone® technology, such as our resin shower trays, bathroom countertops and shower panels. This technology features a body whose mass allows cutting without affecting its integrity or colour based on mineral fillers bound with recycled polyester resins. Depending on their geometry, most of our shower tray models are cuttable on‑site, which offers great advantages for installers.
The most natural adaptability to bathroom spaces.
Tools and materials necessary to perform a cut on the shower tray
Spirit level and measuring tape
Before beginning the cut, it is essential to take exact measurements and verify the horizontal alignment of the shower tray. An incorrect slope or a millimetre error may compromise the installation. This step ensures that the cut is precise, safe and functional.
Rotary hammer or angle grinder with diamond disc for resin and mineral load
To cut materials such as Acrystone®, a powerful angle grinder with speed control is recommended. The cut must be continuous, without abrupt stops, and always with active protection measures. This tool enables clean cuts without fracturing the material.
Diamond disc specific for mineral load / resins
The disc should be thin, with segmented or continuous design, and suitable for technical materials. An inappropriate disc can generate micro‑cracks. The ideal diameter is usually between 115 and 125 mm, depending on the required cutting depth.
Personal protection (gloves, goggles, anti‑dust mask)
The fine dust released during the cut can be harmful if no precautions are taken. The anti‑dust mask, abrasion‑resistant gloves and sealed protection goggles are essential to work safely in environments with resin dust.
Pencil or marking pen and straight edge rule
To mark the cutting zone with precision. The line must be clear and exact, especially for curved or irregular trims. Using a long metal straight edge improves precision and reduces deviations, ensuring the final result is aesthetic and functional.
Industrial vacuum or wet/dry vacuum cleaner
Allows keeping the work area clean and free of debris. By vacuuming the dust immediately, you avoid its accumulation on the tray surface, which could affect the disc’s sliding and create burrs. It also prolongs the tool’s lifespan.
Belt or disc sander (grit 80‑120)
Once the cut is complete, it is important to smooth the edges to avoid sharp edges or burrs. A medium grit (80‑120) is recommended to achieve a smooth finish and ready for sealing. This step also improves the adhesion of the subsequent silicone.
Neutral silicone and sealing cartridge
Neutral silicone is essential to ensure a durable and flexible seal. It is applied around the cut edge to prevent water infiltration and guarantee watertightness. Using an inappropriate silicone can compromise the installation in the medium term.
Technical recommendations before cutting a shower tray
Before making a cut, it is important to take into account a series of technical aspects to ensure a clean, safe job and error‑free. Although mcbath shower trays are designed with high‑resistance materials such as Acrystone®, it is essential to follow good practices to preserve their structural and aesthetic integrity.
Check if the shower tray is cuttable
Not all shower trays are designed to be modified. mcbath’s cuttable models allow adaptation to irregular spaces without compromising their strength or watertightness. It is essential to review the technical data sheet of the model and check the recommended cut limits.
Always consult the manufacturer’s instructions
Each tray may have specific specifications regarding minimum cutting depth, non‑modifiable zones or tool recommendations. Reviewing the technical documentation ensures that the cut is carried out within the established safety margins.
Protect visible edges with masking tape
To avoid chipping or splintering in the cutting zone, it is recommended to apply masking tape on both sides of the marked line. This stabilises the cut, prevents irregular vibrations and maintains a clean aesthetic on the edge.
Cut in a safe and ventilated environment
Dust generated when cutting resin and mineral‑filled trays must be evacuated in a controlled manner. Working in ventilated spaces or using an industrial vacuum connected to the angle grinder is key to safety and cleanliness of the work area.
Make a test cut on a non‑visible edge (optional)
If the installer has not previously worked with a certain tray type, they may make a small test cut in a non‑visible corner. This allows adjusting pressure, verifying material response and ensuring precision before the final cut.
How to cut a resin shower tray if you are an installer
If you are an installer and are looking for materials that allow more cost‑effective interventions, our resin shower trays provide great advantages in terms of speed, efficiency and safety in the final fit‑up.
In addition to their light weight for transport and handling, they can be cut in‑situ without causing damage to any of their layers. Through this on‑site cut a more perfect and detailed adjustment is achieved, without loss of quality or manufacturing guarantee and without waiting times, which means the cut and installation can be done the same day.
We show you step by step how to cut our resin shower trays:
Step 1: Measure meticulously
We measure the space and each of the cuts we need to carry out.
Step 2: Cutting process
We cut the shower tray using a diamond‑disc angle grinder always respecting the cutting limits indicated for each tray model. To ensure a clean cut and avoid burrs, the grinder must not be stopped during the cutting process.
Step 3: We position the shower tray
We embed the shower tray into the space and finish its fixation.
Since in this streamlined process the final finish of the cut edge is omitted, we recommend performing the cut on the side that will remain embedded, leaving the cut edge hidden.
However, if embedding that cut side is not possible and you want the highest quality finishes without giving up same‑day installation, you can request factory‑cut to measure, where we can not only manufacture to measure, but also adjust to the millimetre and deliver defined aesthetic finishes so that the cut edge that remains visible is 100 % aesthetic.
This is how we cut and refine the shower tray so that the visible cut edges are 100 % aesthetic.
How we cut a resin shower tray at the factory
- Step 1: Precise measurement
-
Measure the space accurately, as well as each of the cuts that you need to make.
- Step 2: Cutting process
-
We cut the shower tray with a diamond circular saw blade. To ensure a clean cut without burrs, make sure you do not stop the saw during the cutting process.
- Step 3: We apply putty
-
We apply putty to the cut edge to give it a protective finish. We then let this dry for the amount of time recommended by the manufacturer.
- Step 4: Sanding
-
We sand the cut edge.
- Step 5: Bevelling
-
We gently round off the edge to produce a safer and more attractive bevelled finish.
- Step 6: Painting
-
To produce the perfect final finish, we protect the surface and apply paint in the same colour as the shower tray, using a spray gun.
