This OkayReview guide delves into the intricacies of setting up a shower drain, ensuring your next shower experience is refreshing and worry-free.

Understanding Different Types of Shower Drains

Various shower drains are available, each suitable for different scenarios. The choice of drain often depends on the flooring material and the specific installation requirements.

There are several types of shower drains available, each designed to cater to different needs and preferences:

1. Compression-Style Drains

These are the go-to choices for many homeowners due to their ease of installation. They attach to the home’s drain pipes using compression washers and nuts.

This type of shower drain is versatile and can be paired with various shower bases, including steel, fiberglass, and acrylic.

2. Solvent-Glued Drains

Made predominantly of PVC plastic, these drains are designed for a more permanent fit. They’re glued directly to the drainpipe, ensuring a watertight seal.

They’re especially recommended if you can access the area beneath the shower, such as an unfinished basement.

3. Tiled Drains

This three-piece drain system is ideal for those who prefer custom-tiled showers. Each part is installed at a different phase of the tile pan installation, ensuring the drain seamlessly integrates with the shower floor.

4. Linear Drains

A favorite in modern bathroom designs, linear drains offer a sleek and contemporary look. They run the length of the shower floor, providing efficient drainage and adding a touch of elegance to the bathroom.

Shower installation knowledge is essential, but pay attention to the lesser-known strategies for keeping your roof dry and healthy.
