1. How to prepare tools and components for installation?

Preparation involves gathering all necessary components and checking their compatibility with your plumbing system. Without this, installation will be interrupted and the risk of errors increases significantly.

Before you begin, make sure you have everything at hand. This helps avoid interruptions during the work.

Essential elements:

• a shower tray matched to the space dimensions,
• a siphon and drainage pipes compatible with the installation,
• a spirit level to check alignment,
• sanitary silicone for sealing,
• basic tools (wrenches, drill, measuring tape).

A well-prepared workspace allows you to focus on precision, not on searching for missing parts.

2. Does the base under the shower tray need to be perfectly level?

Yes, the base must be level and stable, as it ensures proper positioning of the tray. Even small unevenness can cause drainage issues.

Check the surface carefully before installation. This step is often overlooked, but it has a major impact on the final result.

Pay attention to:

• the level of the base (checked with a spirit level),
• cleanliness – no dust or debris,
• proper preparation of the drainage area,
• access to the sewage system.

If the surface is not level, the tray may move or retain water.

3. Positioning the shower tray – what determines the correct level?

Correct positioning means precisely levelling the tray and adapting it to the installation. This is one of the key steps affecting user comfort.

First place the tray “dry” to check the fit. Then proceed with final adjustments.

During positioning:

• install and adjust the legs,
• check the level in multiple directions,
• adjust the height to the drain,
• ensure the tray is stable.

Precise levelling eliminates drainage issues and increases durability.

4. Installing the siphon – where do errors most often occur?

Siphon installation involves creating a leak-proof connection between the tray and the drainage system. This is where leaks most commonly occur.

Before final installation, it’s worth testing the siphon separately. This simple step helps avoid future issues.

During siphon installation:

• ensure seals are correctly positioned,
• tighten components carefully,
• match the drain pipe to the system,
• perform a preliminary leak test.

A leaking siphon means disassembly, so it’s better to check it beforehand.

5. Fixing the shower tray – how to ensure stability?

Fixing involves stabilising the tray and preventing movement. It’s not about force, but precision and the correct sequence of steps.

After positioning and connecting, make sure everything fits properly. Only then proceed with final fixing.

At this stage:

• connect the siphon elements,
• perform a water test,
• secure the legs (e.g. with silicone),
• weigh down the tray to prevent movement.

A stable structure ensures comfortable use.

6. Sealing the shower tray – why should it not be skipped?

Sealing prevents water from escaping outside the tray. This step directly affects bathroom protection.

Applying silicone requires precision and patience. Rushing is the most common mistake.

During sealing:

• apply silicone evenly along the edges,
• smooth the joint for a better finish,
• remove excess,
• allow to dry completely.

Proper sealing protects against leaks.

Final test – how to check everything works properly?

The test involves checking for leaks and ensuring proper drainage before use. This is the final but very important step.

Do not skip it, even if everything looks fine. Water will quickly reveal any issues.

Check:

• for leaks under the tray,
• whether water drains properly,
• whether the structure is stable,
• whether the silicone seals the edges well.

If everything works correctly, you can use the shower without concern.

FAQ

Does a shower tray always need to be installed on legs?

No, installation on a base structure is also possible, but requires proper preparation of the surface.

Can silicone be replaced with another material?

No, sanitary silicone is best suited for wet environments.

Does installation require drilling into the floor?

Not always. In many cases, stabilisation with silicone or a frame is sufficient.

Does the tray need to be insulated from the base?

In some cases yes, especially for low-profile models and linear drains.
