How to install a shower enclosure: step-by-step DIY guide

A shower enclosure is a complete package: tray, profiles, glass and door. That makes fitting it a job many DIYers can do themselves, as long as you work precisely. This blog explains step by step how to go about it and what to look out for.

⚠️ Glass panels are heavy and can be dangerous if lifted or fitted wrongly. Always work with two people and wear gloves. If you are unsure about the waste or pipework, call in a registered plumber. A professional is never superfluous.

What do you need to install a shower enclosure?

Which materials do you need?

• A shower enclosure, for example the Larga shower enclosure with tray, or a separate Tako Slim shower tray with siphon with a suitable screen.
• Neutral sanitary sealant such as neutral sanitary silicone and blue painter's tape for a neat joint.
• universal expansion plug and screws according to the manufacturer's instructions.
• A Fila Zero Sil silicone remover if you need to remove old sealant.

Which tools do you need?

• A tape measure with auto-lock and 60 cm spirit level.
• A cordless drill driver or hammer drill, depending on the wall, and a screwdriver set.
• A sealant gun.

Which protective equipment do you need?

work gloves with nitrile coating, safety goggles when drilling and knee pads for work on the floor.

Preparation

Measure the room and compare the dimensions with the enclosure. Check that the waste matches the position of the tray and that the wall is firm and flat enough. Read the manufacturer's instructions completely and lay out all parts. Turn off the water supply if you change pipework.

Step by step: how to install a shower enclosure

1. Remove the old enclosure and make the base clean, flat and dry.
2. Place the tray and level it; connect the waste and test for leaks.
3. Place the profiles against the wall and mark the drill holes with a spirit level.
4. Drill the holes, insert plugs and screw the profiles on.
5. Fit the glass panels and the door according to the instructions; work with two people.
6. Adjust the door and check that it closes smoothly.
7. Tape off and seal the joints with neutral sealant; let it cure according to the packaging. Read more in our blog on resealing a bathroom with new silicone.
8. Only use the shower after the sealant has cured.

Common mistakes

• Not fitting it level, so the door jams or leaks.
• Tightening screws too hard on glass.
• Applying sealant to a wet or greasy surface.
• Working alone with heavy glass panels.

💡 Lay out all parts in advance and compare them with the list. That way you will not be missing screws halfway.

Working safely

Always lift glass panels with two people and wear gloves. Do not drill into pipes or cables; use a detector if needed. You can read more about safe working in our blog on safe working on the construction site.
