2) What Glass is used for Shower Screens and Panels?

In the UK, USA and other Countries, Glass has to be Toughened or Tempered Glass. Glass supplied as ready-made kits can be as thin as 5mm thick however if you go for a bespoke or custom made glass, you would expect to use either 8mm,10mm or 12mm glass.

3) How thick should shower glass be?

For Custom made glass or Bespoke Frameless glass the glass is usually 8mm, 10mm or 12mm in thickness. For bath panels this can be 6mm in thickness. For off the shelf glass, the thickness can be as low as 5mm glass. We recommend that all shower glass starts at 8mm.

4) Are Frameless Shower Doors safe?

If a frameless shower door is installed correctly and at the right thickness it will be safe to use for many years. If an incorrectly installed frameless door struck a tile or the correct rubbers or inserts are not used, this could potentially cause the door to break. Also wrenching the door or not treating it correctly can cause damage.

5) Are Shower Screens made from safety glass?

For Building Regulations and for general safety to human beings, shower doors should be Tempered or Toughened. This process will strengthen the glass and if the glass were to unfortunately break, the glass would shatter into small ice-cube shaped pieces. Although they can cut you, generally it's not life-threatening.

If the glass is not toughened it could break into large shards that could certainly cause much more damage than toughened glass.

6) What way should a shower door swing? In or out?

Good practice says that a shower door should open outwards in case of a slip or fall that will allow easy access for assisted help to that person such if that were to unfortunately ever happen. A door can swing in and out if the room allows for this type of set-up. 

7) Do Frameless Shower Doors leak water?

A well-planned shower enclosure will minimize any leak, that said there are small gaps to consider where you find the hinges on most bespoke glass doors.

You could use a continuous shower door hinge to overcome this problem. Frameless Glass Doors usually have seals supplied that are placed on both sides of the door and a wipe seal that will go across the bottom of the door. You could also consider a threshold.

8) How do frameless shower doors work?

Frameless shower doors are usually mounted either to an adjacent Glass Panel with hinges or directly to a wall. The fixed panel can be mounted by using a U-Channel or Glass Clips or could be just sunken into the tiles. To stabilize the glass you will find plenty of supporting arms, braces and brackets.

9) Why did my shower glass shatter by itself?

On the rarest of occasions, the best explanation is a Nickle inclusion that can be found in the glass itself. When the glass heats up or cools down, it does so at a different rate to the rest of the glass and can cause spontaneous breakage. Another reason could be that poor installation or the glass has simply moved from its original position and is striking a tile for instance.

10) What is the smallest size shower door width?

Ideally the minimum size for a shower door should be 600mm however smaller sizes have been produced. we have had doors that are specifically made for pets that are only 400mm wide and 1200mm in height. It does depend on the user and the application.

11) How long does it take to install a frameless shower?

For a Shower Glass Door alone it could take up to 2 hrs for a fixed glass panel and a door it could take 3-4 hrs and a fully bespoke shower it could take 4-6 hrs. A bespoke sliding door with 2 or 3 panels can also take up to 6 hrs to complete, this would include all cleaning and adjustments.

12) What's the difference between a framed and frameless shower.

Generally, framed shower screens can be bought off the shelf and they would have a bold or thicker frame that surrounds every part of the glass. A semi or frameless shower has the minimum amount of fittings surrounding the door and enclosure and is usually bespoke or custom in nature.

13) How wide does a walk-in shower screen need to be?

Depending on the type of tray, the position of the shower head and the pressure of water that comes out all determine the width of a shower screen. Normally 1200mm or larger is sufficed to cover any water that could otherwise splash into the bathroom area.

Quite simply its a glass panel. A complete wet-room design would not have the need for a glass screen as the whole floor area would be designed to allow for this.
a walk-in shower would normally have only a certain area that can accommodate a wet area, a glass panel would help with keeping the water confined to this area only.

17) Do Frameless Shower Doors or Frameless Shower Enclosures add value to my home?

Low Iron Glass has less of a green edge than Regular Glass. Low-Iron glass has more of an Aqua colour on the edges, the larger the glass the darker the edge of the glass becomes.

22) Is tempered glass fragile? 

Tempered glass can be 4-5 times as strong as regular non-tempered glass and is extremely hard to break on the flat surface, this includes bending of the glass. However, the edges of the glass are the weakest area and even if gently hit can damage a corner/ splinter the edge or worse case destroy the whole panel.

23) What's the widest a shower door can be?

Depending on the Hinge configuration Glass Shower Doors can be ordered up to 1000mm in width and approx 60 Kgs in weight so that would mean a 12mm thick glass door could be 1000mm wide by 2000mm in height. In 10mm it would be 1000mm wide x 2400mm in height.

Clear glass is ideal at home as normally most people will have a lock on the bathroom/ shower room door. Some people will choose a mixture of clear glass with a privacy strip.
