As home improvement tools and guides have become more readily available, DIY home improvement projects have grown in popularity. You no longer need to hire a potentially expensive professional to a job around the house, such as installing a new shower drain in your bathroom. If you follow some basic guidelines, you will find that installing a shower drain is not overly difficult.
Before you start installing your shower drain, you first need to understand how a shower drain works. There are several components to a shower drain, which work together to drain water effectively out of your shower and down into your drainage system. The cap is the part of the shower that you see when you first get into the shower. It is a small piece of metal or plastic which covers the opening of the shower drain. Caps can help stop hair and soap pieces going down the drain and clogging it. Caps usually just screw into place, so are very easy to install.
The surface at the bottom of your shower, where you stand, is called a collector, or a pan. This is usually made with a non-slip surface, and may slope into towards the centre where the drain and cap are placed. The pan will have a small wall around the outside to stop water escaping and flooding your bathroom. While you can build a pan for your shower yourself, it is far easier to buy one from your local home improvement store. You should try a get a pan that has the drain in the same place as the original pan of the previous shower. This saves you having to start trying to shift drain pipes around, a tricky and potentially expensive job. Moving the drain pipes will mean opening up the floor and either trimming or lengthening the pipe.
Underneath the shower and underneath the floor of your bathroom will be the series of pipes which form your drain system. Water from your shower flows down into this main drain, which is usually in a “U” shape. The U shape forms a kind of trap where unwanted debris is caught to prevent it clogging up the drain. The water will then meet up with the water draining from your toilet and sinks before emptying into the sewer system.
The drain pipe under the shower should be going vertically up towards the pan. You will need to create a water tight seal between the drain cap and the drainage pipe to stop leaks. This can normally be achieved by placing a coupling piece on top of the drain pipe, which is then screwed into the drain cap. Plumbers putty is then placed between the cap and the shower pan to further seal the area and protect against leaks.
