How Best to install a Stone Resin Shower Tray

If you have chosen to install a New Stone Resin Shower Tray before you start we will always advise to read the manufactures instructions fully.

Although these instruction are comprehensive we will always recommend that a technically competent installer undertake the installation.

However should you choose to install the shower tray yourself we have a helpful step-by=step guide to help make your installation a simple and easier process to complete.

Before you begin to Unpack your tray check that the tray you have is the correct colour, shape, size and type you ordered? as mostly once these have been opened and removed from the manufactures packing they are Non returnable.

Once you are happy that you have the tray required to fit your space then proceed to unpack and check it further for any damage that was not immediately visible due to the protective packaging.

DO NOT install if you are not satisfied and contact your supplier.

When considering your installation method, you should be able to attach or repair your waste or waste outlet in-situ.


When handling your shower tray take care not to damage the bottom edges and when installing take particular care to protect the visible surface from impact damage or abrasions.

Safety Note:

These are heavy products and require a 2 -person lift.

Care & Use of Your Shower Tray:

The installation instructions should be retained for possible future reference.

The shower tray can be maintained in a as new condition for many years just by following a simple cleaning procedure as follows:

It is normal for a small amount of localised water to be retained on the shower tray surface after use which should be wiped dry to prevent a build up sediment.

The shower tray should be cleaned regularly with warm, soapy water only and dried with a soft cloth. Never use scourers, abrasives, bleach or other chemical cleaners.

Now we have that part out of the way here are your easy to follow instructions:

Installation - Solid Floor

To start place the shower tray into position on the floor

(ensuring surface is level) and mark the perimeter and waste hole on the floor including an area outside the perimeter for access to connect plumbing ( as dictated by the installation location) after the tray has been installed.

Form a trench in the floor to hold the waste unit and piping.

Before proceeding, dry fit all items in-situ to ensure compatibility.

Install your waste unit and piping in the trench in accordance with building regulations, protecting any exposed threads with masking tape.

If necessary, blank off the trench with 18mm ply with waste outlet hole, ensuring that the plumbing connections can be made once the tray is in position.


Most shower trays have a clear or coloured protective film which MUST now be fully removed, undertake a final inspection of the tray at this point. DO NOT proceed if not happy.

Now you are happy with everything you are ready to proceed to the next step:

Mix fine sand, cement and cement additive in accordance with the manufactures instructions to a workable mix to cover the total area underneath the tray. Trowel to a thickness suitable to allow levelling and full support of the tray.

Note! Silicone sealants, foams, mastic, installation compound adhesive or similar MUST NOT be used as a suitable cement.

Place the shower tray onto the wet cement ensuring that it is fully supported. Check the level of the top rims only as the shower tray has built-in fall for adequate drainage.

Remove any excess cement and allow to set fully before continuing.

When the cement has set, make connection between the shower tray and waste unit/piping.

The shower tray and all connections MUST be checked for water tightness, flow and adequate drainage over the entire area.

DO NOT proceed if not satisfied.

After all checks and adjustments have been carried out and you are satisfied you can then proceed to commence with your tile/board then seal along the the finishing line with a good quality silicone sealant.

Finally fill in any access areas and waste pipe trench beneath the shower tray with cement to give full support of the tray when in service.

If fitting an enclosure refer to the manufactures installation guide.

Important Information

Installation of your shower tray may not always allow you to fit directly onto the floor surface, in this case you can use the manufactures recommended Riser Pack kits to lift the tray allowing both installation and access for the waste unit and pipework. ( See our blog for Panel Riser Packs )
