Inflation is at an all-time high in the UK, raising the cost of everything including home improvement. That makes budgeting for a bathroom makeover, especially when it comes to pricey items like shower enclosures, has become quite a challenge. It is due to the cost of installation alone often surpassing the price of the installation itself. 

In such circumstances DIY-ing appears to be the only option when you want to install a  shower enclosure to save money. 

But is it an option? 

If it is, how much can you save, and what’s the best way to DIY a shower enclosure installation? Our blog will provide you with answers to all these questions, offering complete guidance on making the DIY shower enclosure process easier.

“Shower enclosures are enclosed shower spaces usually made with glass shower panels and shower doors. A shower tray is often its base around which these panels are installed. 

These are available in various shapes and sizes with the most common position of fitting is bathroom corner”.

Before getting any further it is important to clarify that DIY installation is not for you if you are the first time DIYers. In other words, you can install your shower enclosure on your own but only if you are highly experienced.

Shower trays are the base of a shower enclosure (unless you are going for a walk-in shower). To install the shower tray, follow the process here. 

  • Place the shower tray at the right position.
  • Use spirit level to make sure it’s leveled. 
  • Adjust its riser kit or use shims to level it.
  • Follow the manufacturer’s instructions to secure the tray on the floor.

Sometimes you need to assemble the shower enclosure frame before you install a shower enclosure. If it is the case, then follow the manufacturers guidelines to assemble it. You will need to double check that all the frame components are secured tightly. 

Step 5# Wall & Corner Profiles (If Applicable)

If you have selected the quadrant shower enclosure, then it may come with a wall and corner profile. And you will need to first install it and secure it according to manufacturer’s guidelines. 

Step 6# Wall Adjustment (if needed):

In case your bathroom walls are uneven, then you will have to adjust the shower cubicle components accordingly. Additionally, the use of shims and spacer is recommended as it will help in proper fitting against the wall. 

Step 7# Mount the Enclosure:

So, now comes the real deal in our quest to install a shower enclosure! 

Follow these steps to mount the enclosure in the bathroom corner. 

  • You will need to lift and place the shower enclosure ( assembled) into the required position. It will not be possible for you alone to do it. So, ask a second person to help you with it. 
  • Use screws to the walls using screws and anchors( drill in the holes in the required position if you have not already done it)
  • Check the level of the frame with spirit level and make adjustments as needed. 
  • You will need to make sure all the screws are tightened perfectly. 

Step 8# Install the Doors

Quadrant shower enclosures always come with a shower door. You will need to fit the shower door once the shower enclosure is in its place. While shower doors installation may differ slightly based on whether its pivot, sliding or bifold doors. You will need to follow the manufacturer’s instructions. 

  • Adjust the shower door at the entrance position for your shower enclosure
  • Tightened the screws provided with the door installation kit. 
  • Make sure that seals are properly in place to avoid water leakages. 
  • Ensure that any seals or gaskets are properly in place.

Step 9# Seal The Gaps:

At the final step as you install a shower enclosure, you will need to look for the gaps and joints to seal them. Use a caulking gun to apply sealant between the gaps in walls and enclosure. You will need to pay special attention to the areas around the tray and frame. 

Step 10# Final Checks

To conduct final checks, you will need to run water in the shower, so you know if water is completely concealed inside and not seeping through any areas. You will also need to check drains and connections for water leakages. Additionally, check how the shower doors operate, adjust if necessary. 

*Check your shower enclosure periodically for any leakages and any other problems.
