The shower cabin has arrived, it is still in boxes — and then you find out that assembling it is not as easy as it looked. The tray needs to be dead level, the drain trap has to meet the waste pipe at the proper angle, the panels must be fixed straight, and every joint needs sealing. In flats around Praga Poludnie and new developments in Wilanow we see the same problems: uneven floors, short pipe runs, cramped bathrooms. We take care of shower cabin installation from unboxing through to leak testing.

How much does installation cost

The cost depends on the type of cabin (corner, wall-mounted, high or low tray), how tricky the plumbing connection is, and the condition of the bathroom. If the water feed has to be extended or the waste outlet moved, the price increases. Current rates for all bathroom work are listed in the table below. Fixings and sanitary silicone are included; the cabin itself and any plumbing materials are provided by the client.

How the installation works

1. Bathroom inspection: we check where the waste outlet sits, the pipe diameter, and access to the riser. We also measure the space for the cabin.
2. Unpacking and inventory check: we match the parts to the instruction sheet and inspect the glass panels and profiles for damage. If something is missing, better to find out before assembly begins.
3. Tray installation: we level it with the adjustable feet, connect the drain trap to the waste pipe, and check the fall — water needs to drain fast with no standing water.
4. Frame and rail assembly: aluminium profiles are fixed to the walls and lined up vertically and horizontally. We drill tiles carefully — with a tile bit, no hammer action.
5. Glass panels and door fitting: panels are mounted on rollers and the door movement is adjusted so they slide freely and close without gaps.
6. Sealing: sanitary silicone is applied to every joint between the profiles, the wall, and the tray. We use mould-resistant silicone only.
7. Final test: we turn on the water, inspect every joint for leaks, and run the drain under load. The client checks the result before we leave.

The full installation takes between two and four hours depending on the cabin design and the condition of the plumbing (compatible with Grohe, Hansgrohe, Geberit and similar).

Common installation mistakes

• Tray not level — water collects in one corner instead of running to the drain. Then mould starts.
• Drain trap connected without enough fall or with a reverse slope — water drains slowly and the trap starts to smell.
• Profiles screwed to the wall without silicone behind them — water gets behind the cabin, the wall becomes damp, finishes start to fail.
• Tiles drilled in hammer mode — cracks and chips, and the tile needs replacing.
• No inventory check before starting — a missing part found halfway through assembly.
• Standard silicone used instead of sanitary grade — joints go black with mould within a few months.
• Doors left unadjusted — they do not shut properly, and water sprays onto the floor every time someone uses the shower.

What to prepare before the visit

• The shower cabin — complete, ideally with all parts checked against the instruction list.
• Clear access to the installation area — remove old cabinets, shelves, and bath mats.
• If replacing an existing cabin — the old one should be removed beforehand (or book removal separately).
• The waste outlet must already be in place and working. If the pipes are old or blocked, tell us.
• Hot and cold water supply — with shut-off valves so the water can be turned off during installation.
• Wall tiles in the cabin area must be laid and grouted.
• Electricity in the bathroom — for the drill and driver.
• If the bathroom is very tight, let us know in advance so we can plan the assembly order.

A real case from Warsaw

We were called to a flat in Praga Poludnie. The owners had bought a 90 x 90 cm corner cabin with a high tray. The bathroom was small, and the waste outlet was 15 cm away from where it had to be. We extended the pipe with a flexible connector and fitted a trap with a side outlet to keep the correct fall. The tray was levelled on its feet, connected, and tested — water drained quickly. We assembled the frame, hung the glass panels, and adjusted the doors. Silicone was applied around the entire perimeter. Water on — completely dry, not one leak. The job took three hours. The owners have been using it for six months with no complaints.
