Shower Cabin Installation in Warsaw — Assembly and Plumbing Connection

The shower cabin has been delivered, it is sitting in boxes — and then it turns out that putting it together is not as simple as expected. The tray has to be perfectly level, the drain trap connected to the waste pipe at the right angle, the panels fixed plumb, and every joint sealed. In flats around Praga Poludnie and new developments in Wilanow the issues are the same: uneven floors, short pipe runs, tight bathrooms. We handle shower cabin installation from unboxing to leak testing.

How much does installation cost

The price depends on the cabin type (corner, wall-mounted, high or low tray), the complexity of the plumbing connection and the condition of the bathroom. If the water supply needs extending or the waste outlet needs relocating, the cost goes up. Current rates for all bathroom work are in the table below. Fixings and sanitary silicone are included; the cabin itself and any plumbing materials are supplied by the client.

How the installation works

1. Bathroom inspection: we check the waste outlet position, pipe diameter and access to the riser. We measure the space for the cabin.
2. Unpacking and inventory check: we compare parts against the instruction sheet and inspect glass panels and profiles for damage. If anything is missing it is better to know before assembly starts.
3. Tray installation: we level it using adjustable feet, connect the drain trap to the waste pipe and check the fall — water must drain quickly with no pooling.
4. Frame and rail assembly: aluminium profiles are fixed to the walls and aligned vertically and horizontally. We drill tiles carefully — with a tile bit, no hammer action.
5. Glass panels and door fitting: panels are hung on rollers and the door travel is adjusted so they slide smoothly 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, check every joint for leaks and run the drain under load. The client inspects the result before we leave.

The whole installation takes between two and four hours depending on the cabin design and the state of the plumbing.

Common installation mistakes

• Tray not level — water pools in a corner instead of reaching the drain. Mould follows.
• Drain trap connected without enough fall or with a reverse slope — water drains slowly, the trap smells.
• Profiles screwed to the wall without silicone behind them — water seeps behind the cabin, the wall gets wet, finishes deteriorate.
• Tiles drilled in hammer mode — cracks and chips, the tile has to be replaced.
• No inventory check before starting — a missing part discovered halfway through assembly.
• Standard silicone used instead of sanitary grade — joints turn black with mould within a few months.
• Doors left unadjusted — they do not close tightly, water sprays onto the floor every time someone showers.

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 in advance (or book removal separately).
• The waste outlet must be in place and working. If pipes are old or blocked, let us know.
• Hot and cold water supply — with shut-off valves so 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, tell us in advance so we can plan the assembly sequence.

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 needed to be. We extended the pipe with a flexible connector and fitted a trap with a side outlet to maintain the correct fall. The tray was levelled on its feet, connected and tested — water drained fast. We assembled the frame, hung the glass panels and adjusted the doors. Silicone was applied around the full perimeter. Water on — completely dry, not a single leak. The job took three hours. The owners have been using it for six months with no complaints.

Frequently asked questions

Can I install the cabin myself?
Technically yes, but there are pitfalls: the tray must be perfectly level, the trap connected correctly and every joint sealed. A mistake at any stage leads to leaks. If you have no experience it is safer to call a professional.

How long does installation take?
Two to four hours on average. It depends on the cabin type and the state of the plumbing. A cabin with hydromassage or a steam generator takes longer.

Do I need to remove the old cabin first?
Yes, and that is a separate job. We can do the removal during the same visit, but please let us know in advance.

What if the waste outlet does not line up with the drain?
We extend the pipe using a flexible connector or rigid elbows. The key is to maintain the fall for proper drainage. If the distance is large the outlet may need to be relocated — that counts as plumbing work.

Which sealant should be used?
Sanitary silicone with anti-mould additives only. Standard acrylic or universal silicone grows mould quickly in a wet environment.

Cabin with a tray or without — which is better?
A tray cabin is easier to install and cheaper. A walk-in (trayless) setup requires floor waterproofing and a linear drain — a different level of work and budget. For a standard bathroom we recommend a cabin with a tray.
