Raw material

Arock®is a new composite versatile material for any production need. This is due to the possibility to adapt its components according to the final intended purpose. The whole Arock® manufacturing process is submitted to severe and accurate quality and technical studies. The gelcoats that protect our Arock® products are also used for naval applications and feature high resistance to chemical and bacteria attacks while polyester resins and natural mineral powders are aggregated according to different ratios according to the final inteded result. Formulae applied to shower trays and wall panels garantee the maximum dimensional stability; at the same time these composite materials can be produced in a large variety of colours and allow customized cuts.

EC test

Arock® products are submitted to dimensional and visual quality tests in order to guarantee the maximum entirety and compliance. Arock® shower trays are regulated by EN 14527:2010 e EN 251 for the technicals aspects and DIN 51097:1992 ranked Arock® shower trays as "B" (A+B) with a average Determination of Slipperiness of 19.2°. Foreign languages versions of the slipperiness test can be downloaded from website.


Arock® shower trays and wall panels maintenance is easy and helps in keeping your product unchanged in time. Use soft clothes and neutral cleaning products, better in liquid form. Do not use aggressive products (ammonia, solvents, alcohol). We recommend to rinse the tray or walls after each shower and dry them with a soft cloth. In case of limestone, use hot water with vinegar and a soft cloth, rinse and dry. For any small damage due to domestic accident a repair kit can be ordered to the factory.


The selection of a shower tray largely depends on available space in the bathroom and the position of the drain. As well as the size, you need to choose a colour that matches the bathroom. TDA has 34 colours for both Arock products (trays and panels) and furniture units.

This is a simple task. Measure the width and depth, the position of the drain and, if you can, the thickness of the screed. With this information we can examine the option of installing the tray on the floor or flush with the floor.

The size of our shower trays is suitable to cover the space occupied by standard bath tubs. They can be completed with ALmuro wall panels to cover the bare horizontal strip resulting after the bath tub has been removed or to create a finish covering the whole vertical area.

Arock trays have the same finish on the 5 visible sides, while the bottom has a special finish suitable for the adherence of the glues used for installation purposes. In the case of a “cut at the finishing stage” made by the manufacturer, the surface on which the “finish” is performed will be slightly smoother.

Arock trays can be cut according to criteria allowing for extreme customisation. The chance of having “cuts at the finishing stage” further extends this option. Adapting a tray to a recess or an out-sized design is a simple operation that can also be performed on site.

Like the whole of the Arock range, the ALmuro wall panels allow for extreme customisation, both on site and directly on the company’s premises. Drilling the holes during installation allows for a clean job with no imperfections.

Yes, the waste is always included.

Wates normally sold are 8cm to 10 cm high. TDA standard waste is 4 cm high, easy to install in very reduced spaces.

Arock tray grids are made of stainless steel with a mirror brushed side and a side with a satin finish. They are cut with a high-precision laser and, if required, painted with a special cycle with the same finish as the shower tray.


We recommend using KERALASTIC by Mapei (or a similar product) to install Arock items. Follow the assembly instructions included in the packaging to install our products correctly.

The option of cutting Arock products during installation is one of the benefits provided by these innovative materials. You will need a diamond disc cutter similar to the one normally used to cut marble or tiles. To make holes in the panels, you just need an HSS bi-metal cup saw.

Except in the case of specific building standards, there is no need for an insulating membrane when using our products as they are 100% leak-proof. Unlike mosaics and/or tiles, once they have been installed they allow water to flow towards the floor.

The wall panels are very flexible and can adapt to the conditions of the wall. If you cannot fully compensate for the out-size design of the wall with the lack of levelling of the tray, you can use sealing silicones or cut the panels during installation.

When installing the tray, it is always a good idea to make sure it is levelled and that all the edges have the right slope gradient. To perform this check, just use a small ball and watch where it rolls.


Use soft cotton cloths and neutral detergents, preferably liquid ones, for cleaning purposes. Do not use abrasive cloths or sponges, ammonia, alcohol, acetone, thinners, organic solvents, etc. After cleaning, rinse well with plenty of water to remove any residue. After each use, rinse the trays and/or panels with clean water and dry with a soft cloth.

We have created a special Touch-up kit available in all the colours of the range for small domestic accidents that may leave chips on Arock products. You can repair the damage very quickly by following a few, simple operating instructions.

To solve the root of the issue of limescale, it is best to get a water softener. If this is not possible, you can use products available on the market by leaving them to act for a short amount of time and testing them in a small concealed area before using them. Limescale can always be removed by wiping the area you need to clean with a cloth dampened with hot, white vinegar.

Special waxes are used during the manufacturing stages to protect the gel-coat when the mould is removed. Despite the fact of being cleaned with high-pressure hot water jets, sometimes these waxes can slow down water flowing out. Wash the tray with soap and the issue will be solved after using the shower a few times

To remove organic residue just lift the stainless steel grid covering the siphon and clean it with normal bathroom detergents. Then follow the siphon’s instructions to remove the residue captured by it.


As with all TDA products, Arock products come with a two-year warranty from the date of purchase. To claim your warranty, keep the invoice or receipt showing your purchase, otherwise you will not be able to request the warranty.

The Touch-up Kit for Arock is available from all our retailers. We recommend contacting the retailer where you purchased the product to be sure they have the colour code installed.
