How to Choose the Right Double Sliding Bathtub Doors for Your Bathroom

If you're planning a bathroom upgrade or renovation, installing double sliding bathtub doors is one of the smartest decisions you can make. Not only do they provide a sleek, modern look, but they’re also incredibly functional—especially in bathrooms where space is limited.

In this guide, we’ll walk you through what to look for when shopping for double sliding bathtub doors so you can find the perfect fit for your space and style.

What Are Double Sliding Bathtub Doors?

Double sliding bathtub doors, also known as bypass tub doors, are made up of two glass panels that slide past each other. This design allows entry from either the left or right side of the bathtub, making them extremely versatile and ideal for smaller bathrooms.

Compared to traditional shower curtains, double sliding doors offer:

• A cleaner, more polished look
• Better water containment
• Easier maintenance
• A more modern and durable solution

1. Start with Accurate Measurements

Before choosing your door, measure the width of your bathtub from wall to wall. Also measure the height from the top of the tub to where you want the doors to reach. Most standard double sliding bathtub doors fit tubs that are 56"–60" wide, but adjustable models are available to fit uneven walls.

Look for adjustable hardware or wall brackets that can accommodate slight variations during installation—especially if your walls are not perfectly plumb.

2. Choose Your Glass Style

Glass type has a huge impact on both the look and feel of your bathtub door. All quality double sliding bathtub doors use tempered safety glass, but you can choose from different styles:

• Clear glass: Creates an open, airy feel
• Frosted glass: Offers more privacy
• Low-iron or “crystal clear” glass: Reduces the green tint of standard glass
• Easy-clean coating: Helps prevent water spots and soap buildup

For a modern look, many homeowners prefer clear glass with an anti-spot coating.

3. Hardware Matters

Hardware is more than just the frame or track—it defines how your doors function and how long they’ll last. When choosing your double sliding bathtub doors, pay attention to:

• Roller size (e.g., Ø45mm or Ø55mm): Larger rollers glide more smoothly
• Track material: Stainless steel or anodized aluminum for durability
• Finish options: Matte black, brushed nickel, chrome, or gold to match your bathroom
• Reversible design: Allows for left- or right-side entry
• Threshold depth: Some models require a minimum tub ledge depth to install properly

Matching the hardware finish to your faucets or showerhead can tie the whole look together.

4. Frameless vs. Framed Doors

You’ll find both framed and frameless versions of double sliding bathtub doors. Each has its benefits:

Frameless doors

• Sleek and minimal
• Easier to clean
• Ideal for modern bathrooms

Framed doors

• Often better at preventing leaks
• More budget-friendly
• Slightly easier to install

If you prefer a luxury feel and minimalist look, go frameless. If you’re looking for value and function, a framed option might be the way to go.

5. Installation Tips

Many double sliding bathtub doors are designed for DIY-friendly installation. Look for products that include:

• Step-by-step instructions
• Adjustable wall brackets
• Pre-drilled holes for easy alignment
• Support for uneven walls

Still, if you're not confident in your tools or time, hiring a pro can ensure a smooth, watertight fit.

6. Budget Considerations

Pricing for double sliding bathtub doors can range from $300 to $900 or more depending on glass thickness, design, and finish. While it's tempting to go with the lowest price, remember that higher-quality doors offer better durability, smoother operation, and more polished aesthetics.

Think of it as an investment in the comfort and long-term value of your home.

Final Thoughts

Whether you’re replacing an old curtain or designing your dream bathroom, double sliding bathtub doors offer a stylish, space-saving upgrade that fits right into modern life. With the right size, hardware, and finish, you can easily transform your bathtub into a functional focal point.
