Description

Geberit Sigma50 Dual Flush Plate - Lava Glass & Brushed Chrome - 241.788.JK.2

Geberit Sigma50 Dual Flush Plate in Lava Glass

A glass dual flush plate from the Geberit Sigma50 range. The cover plate is glossy safety glass in Geberit's Lava colour, a deep charcoal grey, over a glossy chrome base with brushed chrome buttons.

Glass is the easiest Sigma50 cover to live with. It wipes clean, it does not vary from plate to plate the way wood does, and the chamfered edges Geberit put on the safety glass mean there is no sharp line where the plate meets the wall. The two buttons are polished die-cast zinc in brushed chrome, easy-to-clean coated. Dual flush, front actuated and entirely mechanical.

Why choose glass over the wood cover plates

Two practical reasons: consistency and cleaning.

1

Every plate looks the same

Glass is manufactured to a colour, so the Lava you receive matches the Lava in the photograph.

  • No grain variation between plates
  • Safe to order two for one property
  • Chamfered edges on the safety glass
2

It handles a family bathroom better

A glossy glass surface takes a wipe far more readily than an oiled wood veneer, and it is unbothered by steam. In a shower room or a busy family bathroom that is the difference that matters day to day.

The three Sigma50 plates we stock

Round 115.884.JX.1 Black walnut cover · round buttons · 246 x 164 x 14mm · view the round plate

Square 115.788.JX.2 Black walnut cover · square buttons · 246 x 164 x 15mm · view the square plate

Lava glass 241.788.JK.2 Glass cover in Lava · 246 x 164mm · (this product)

All three are Geberit Sigma50 dual flush plates for front actuation, so they take the same Sigma concealed cisterns. The choice is the cover material and the button shape.

Lava is a dark charcoal grey rather than a true black. Against a black tile it will read as a slightly lighter grey and against white it looks close to black. If you are matching it to an existing black fitting, order this plate first and check it in the actual light of the room before committing to the rest.

Glossy safety glass in Lava

The cover plate is safety glass finished in Geberit's Lava, a deep charcoal grey that reads close to black in most rooms. Because it is glass rather than wood it is consistent plate to plate and it takes a damp cloth without any special care.

Chamfered glass edges and brushed chrome buttons

Geberit chamfer the edges of the safety glass, so there is no hard line where the plate meets the tile. The two buttons are polished die-cast zinc in brushed chrome with an easy-to-clean coating, which hides fingerprints better than a glossy chrome button would.

Frameless, and easy to keep clean

No visible surround and a flat glass face means there is nowhere for grime to collect at the edge. In a family bathroom or a shower room that is the practical advantage of glass over an oiled wood veneer.

Frequently asked questions

Is Lava black or grey?
It is a dark charcoal grey, and Geberit call the colour Lava rather than black. In a light room it reads close to black. Next to a genuinely black fitting you will see that it is a shade lighter and slightly warmer. If you are matching finishes across a room, order this plate first and look at it in situ.
Is the glass fragile?
It is safety glass with chamfered edges, made for a bathroom wall and rated for the job. It is not a plate you would specify for a school washroom where things get kicked, but in a home or a hotel bathroom it will outlast the decor. For an abuse-resistant plate see the Armitage Shanks Septa Pro M1.
How does it compare with the black walnut plates?
Same range, same cistern compatibility, same footprint of 246 x 164mm. The difference is the cover: this one is uniform glass, while the square black walnut plate and the round black walnut plate use real wood, which varies between pieces and needs more care when cleaning.
Which cistern does a Geberit Sigma50 plate fit?
It is made for Geberit Sigma concealed cisterns using front actuation, which covers the Sigma 8cm and 12cm cisterns found in most Geberit Duofix and Kombifix frames. It will not fit a Geberit Omega cistern, which actuates from the top, and it will not fit another manufacturer's frame. Check what is behind the wall before ordering.
What is the difference between Sigma50 and Sigma21?
They are the same plate. Geberit renamed the Sigma21 range as Sigma50, so you will still see older listings and price lists using the Sigma21 name for these article numbers. If a plumber or a spec document refers to a Sigma21 plate, a Sigma50 with the same article number is the current equivalent.
How do the buttons feel to use?
The buttons are highly polished die-cast zinc with a slightly curved contour, so they have real weight behind them rather than the light click of a plastic plate. Both are easy-to-clean coated, which means fingerprints and water spotting wipe away with a damp cloth.
Can I mount it flush with the tiles?
The Sigma50 is designed to sit close to the wall with a frameless edge, so it reads as a panel rather than a raised fitting. Exact projection depends on how the cistern is set back during first fix, so agree the finished tile depth with your installer before the wall is closed up.
Is this a mechanical or an electronic plate?
Mechanical. It is a dual flush plate with two physical buttons acting on the cistern valve, so there is no battery, sensor or mains supply and nothing to fail in a power cut. If you want a touchless plate you need a different Geberit range.
How do I clean it without damaging the finish?
A soft damp cloth, then dry it off. Avoid abrasive creams, bleach, descalers and anything containing solvent, because these attack the easy-to-clean coating and cannot be undone once the surface is dulled. On the wood cover plates this matters even more than on glass.
What else do I need for a complete installation?
The Geberit frame and Sigma cistern if you are starting from scratch, plus a compatible wall hung pan such as the RAK Moon rimless wall hung WC pan. Send us the cistern model and we will confirm the plate is the right match before you order.
What if I need something tougher for a public washroom?
These are design-led plates for homes and hospitality rather than heavy-duty commercial washrooms. For a school or a high-traffic public toilet the Armitage Shanks Septa Pro M1 is anti-vandal rated and built for abuse. For a plain domestic plate at lower cost, the Ideal Standard Oleas M3 is worth a look.

Unused items in their original packaging can be returned within 14 days of receipt for a refund, with return postage payable by the customer on unwanted or incorrectly ordered items.
