Sliding glass doors: where they fit, advantages and prices

When it is worth choosing sliding doors

Sliding doors open by gliding parallel to the wall. Unlike hinged doors, they do not need free space to swing open — typically saving 0.8–1 m² of floor area. Real situations where this is essential:

• Small bathrooms (a swinging door bumps into the toilet or shower)
• Entries to walk-in closets — open layout matters
• Kitchen-living room link — when zones need to be separated quickly
• Office cabinets with narrow walkways
• Children's rooms — less risk of trapping fingers

Two main variants

Wall-mounted (open track)

The track is mounted at the top above the opening. The glass pane hangs from the track and slides aside. Advantage: can be installed during a renovation, no need to break the wall. Disadvantage: the track is visible (though it looks modern), and the glass pane stays next to the wall. Price: €450–900.

Pocket (cassette system)

A metal cassette is hidden in the wall (installed before plastering). The door slides into the wall — looking as if it were not there at all. Advantage: elegant, saves space. Disadvantage: has to be planned during construction or major renovation, costs more. Price: €900–1500.

Soft-close and silent system

The cheapest sliding doors clatter and slam every time. Premium hardware (e.g. CCE Slim, Dorma Junior) includes a hydraulic slow-down mechanism (soft-close) — in the last 5 cm the door stops itself softly. Price difference: ~€80–150, but it is worth it for comfort and longevity.

Glass thickness and maximum dimensions

Standard — 8 mm tempered glass. Up to a 1 m × 2.2 m opening, that is enough. Larger panes (up to 1.2 m × 2.5 m) require 10 mm glass or a double-track system. Maximum weight per track is often 80 kg, so 12 mm glass is rarely used (only for acoustic variants).

FAQ

Do sliding doors provide privacy?

Clear glass — visually no. But choosing frosted glass, a sandblasted pattern or VSG laminated with a frosted film provides privacy while still letting through ~80% of the light.

Are they suitable for the bathroom?

Yes, but moisture-resistant hardware is important (stainless-steel track, polymer bearings). The bottom edge has a ~5–8 mm gap with the floor, so full sealing against steam is not possible — a shower enclosure is better for that, not a sliding door.

How long does the system last?

Quality hardware withstands 100,000+ openings — about 15–20 years of daily use. Cheap tracks start to skip after 3–5 years.
