How to Install a Shower Door Yourself

Replacing a shower door or fitting a new one as part of a complete overhaul of your bathroom doesn’t need to be something you outsource to a paid professional.

If you want to do it yourself, there are a few straightforward steps to follow to achieve this. So without further ado, let’s dive in and fulfill your shower door DIY ambitions. 

Choose the right door type

There are five main varieties of doors to consider for your shower, and your choice will depend on practical factors like the amount of space you have to work with, as well as aesthetic preferences.

Sliding and folding doors work best when dealing with larger spaces, although folding doors can be surprisingly compact. Pivot doors and hinged doors are very similar and can accommodate smaller space, as well as being able to open in various ways using specific fittings.

Then there are fixed partitions, which remain static while blocking water, neither opening nor closing. These can be standalone for shower cubicles or sit on the side of a bathtub in the case of a combi setup.

Measure up and buy your door

Measure the space in which your door will fit carefully, and get a friend or family member to assist. Using a tape measure, remember to note the dimensions of the entire space, not just the opening which the door will cover.

This is particularly important in the case of hinged doors, as you do not want to choose one which might impede access to the shower when opened.

When buying shower door hardware, it makes sense to get all of the components from the same supplier, as this is both more convenient and easier if you need to return any items further down the line.

Fit the door

Once the door arrives, clear out the shower space and, with the assistance of another person, align the door with the opening it is intended to cover.

Shower doors with frames can be stuck in place temporarily using masking tape to let you see how the fit looks. They can also afford you a little leeway if they are too large, as trimming frames with a hacksaw may be an option.

A spirit level is also needed to check that the door is standing straight. When everything is lined up as you want it to be, make pencil marks on the wall where screws are needed. The door can then be put to one side, and the drilling can begin.

If you are drilling into tile or brick, make sure you have the right bit for your drill to make progress. You can stop the material from cracking by sticking masking tape directly over the area you intend to drill, which is a handy tip for any scenario.

With the holes drilled, you’ll need to prep the door for installation. Bathroom-grade caulk has to be applied to the sides to create a seal between the door and the wall to stop moisture from escaping when the shower is on.

With this in place, you can now align the door with the wall, using the screw holes you made for guidance, and press it into place.

Add the screws and even out the caulking with a finger or a plastic tool, and make sure that everything is tight, straight, and accurate.

Finish up

The caulk will likely have a manufacturer-defined setting period, so wait for this to elapse before using the shower. In the meantime, add any handles or other elements to the door according to the manufacturer’s instructions. And if in doubt, consult an expert rather than getting in over your head.
