6 different ways of fixing a Custom made or bespoke shower screen panel.

Glass clamps for Frameless Shower Screens

What is the best way to secure shower glass to tiles or a shower tray?

Ideally if you can Mechanically fix A U channel or clamp, this is the best and most secure method. Most shower tray manufacturers will dismiss fitting a U channel or clamps to a tray as it will penetrate/ compromise the tray itself however if you make sure any holes are waterproofed once drilled ( silicone sealant) all will be suffice.

The following 6 ways we know are the most suitable

  1. Fitted into tiles/ tile void
  2. Fitted in to a sunken tile U-channel
  3. Fitted into a Surface mounted U channel
  4. Fitted with small feet attaching the glass to a tile.
  5. Fitted with large adjustable feet attaching glass to a tile.
  6. Silicone to tray / bed

By mechanical fixing, It means that there will be no chance of lateral movement for the shower screen or glass panel and thus, will both stay in place and be safe for the user.

There are a few methods for fixing the shower screen as listed above. So, we have decided to list the best ways to fix the shower screen below. This is Ideal for Frameless Shower Screens, Custom shower screens and bespoke glass panels.

  1. Fitting into tiles:
    This works well if you are confident with the lines of the tiles being linear and perfectly straight. The dangers are that if the tiles you are going to drop/ install the shower glass into, might not be 100% aligned and then risk damage to the tile or worse the glass upon installation.

The plus side of fitting directly into the tiles is the asthetical look is really good as there is just glass and tile.
Once the glass is in place you would just silicone the glass in place and the job is complete.

You have to remember that with this method, you don’t disturb the waterproofing / tanking or water protection membrane when dropping the glass onto the floor/ bed.
Ideally use some sort of separation/ packing between the bed and the glass edge.

You could use silicone as a separation between the bed and the glass but this can also get a little mucky!

2) Fitting into recessed/ Sunken U channel

This is very similar to fitting directly into tiles. It’s great for the tiler also, as he/she has a nice straight edge to finish the tiles up to.

The added benefit of this over just tiles is that the glass goes directly into a guide that is both linear and smooth, so the chances of the glass breaking is minimal upon installation.

Generally this type of channel has 2 small lips at the shoulders of the U-Channel, that will sit onto of the tile edge.

The other bonus of using this type of U-channel is you can silicone it into place on both wall and floor so to not penetrate any water membrane. You wont damage any underfloor heating by siliconing the channel either

The visual looks of the U-channel are minimal when choosing this type of Install.

Good news for designers and alike as there are a few different colours available but you could also have the channel powder coated, certainly if the requirement for colour matching is important.

3) Surface mounted U-channel

Surface mounted U-channel is certainly the most popular and the easiest way to install a shower glass panel.

The U channel comes either pre drilled or as a un-drilled version. Supplying companies such as CR Laurence(CRL). Finishes are in a whole variety of colours including the most popular Matte Blacks, Satin Brass and Gold Finishes.

In fact, according to CRL’s website they have 20 anodised and Powder coated U-channels available.

Being the easiest to U-channel to mount, it literally is screw to the wall and floor where suitable. The glass is then fitted.
