How to Convert Your Bathtub into a Shower With Bathtub Doors

Jun 11, 2024Ron Tsantker

Have you ever looked at your bathtub and imagined a more spacious, modern shower in its place? You're not alone! Many homeowners are swapping out old tubs for sleek showers equipped with elegant bath tub doors. Not only does this upgrade make your bathroom look more luxurious, but it also enhances its functionality and accessibility. Let’s dive into how you can transform your bathroom into a sanctuary of relaxation and style.

Assessing Your Current Bathtub Setup

Transforming your bathtub into a shower isn't just about picking the right doors; it starts with a thorough assessment of your current setup. Understanding the layout, dimensions, and constraints of your existing bathtub is the foundation for a successful conversion. Here’s a detailed guide on what to consider before you begin:

Measure Your Space

An accurate measurement is paramount as it influences every subsequent decision from half glass shower door for bathtub size to design style. Follow these steps:

  1. Length and Width: Measure the interior and exterior dimensions of the bathtub area to determine the maximum door size.
  2. Height: Consider the height from the tub base to the nearest overhead obstruction to choose the appropriate door height.

Evaluate the Bathtub’s Position

  • Alcove Bathtubs: These are enclosed on three sides. For alcove setups, sliding shower doors for the bathtub are ideal because they maximize space and offer easy access.
  • Freestanding Bathtubs: Often more challenging to convert, freestanding tubs may require a custom solution like a curved shower door for the bathtub to complement their unique shape.

Consider the Drainage and Plumbing

Plumbing can significantly influence the scope of your project. It’s crucial to ensure that the existing plumbing can accommodate a shower without extensive modifications. If adjustments are needed, it might affect the project timeline and budget.

Structural Considerations

  • Support and Weight: Check if additional support is needed for new glass doors, especially heavier glass shower doors for bathtubs. The structure should safely support the weight without risk of damage.
  • Waterproofing: Ensure the area is well waterproofed to handle the increased exposure to water from a shower. This might involve updating the tiling and sealing around the bath area.

Choosing the Right Bathtub Door

Selecting the right shower tub door can be as impactful as choosing the bathtub itself. Here’s what you need to consider:

Types of Bathtub Doors

  • Sliding Doors: Great for smaller bathrooms, as they don’t require additional space to open.
  • Hinged Doors: These need more clearance but offer a classic look.
  • Frameless Doors: For a touch of modern elegance, frameless doors provide a clean and expansive look.

Material Matters

Glass shower doors for bathtubs are a popular choice for their sleek appearance and the way they allow light to flow through the bathroom. Frameless glass doors, in particular, are highly sought after for their stylish, uninterrupted glass look. You can explore a range of options in our collection of frameless glass shower tub doors.

Design Considerations for Bathtub Doors

Choosing the right bath tub door involves both aesthetic and practical considerations.

  • Style Sync: Ensure that the door style harmonizes with the rest of your bathroom's decor. Whether you prefer a minimalist design or something more ornate, consistency is key.
  • Maintenance and Durability: Opt for materials that are easy to clean and maintain. Glass, especially treated or frosted, can be excellent for reducing soap scum visibility.

Installation Process

Whether you decide to DIY or hire a professional, understanding the installation process is beneficial.

  1. Preparation: Remove the existing bathtub and fixtures. Prepare the area by ensuring all surfaces are clean and level.
  2. Installation: Follow the manufacturer’s instructions to install the bathtub door. This might include securing the frame, aligning the door correctly, and ensuring all seals are waterproof.
  3. Sealing: Apply silicone caulk around the edges of the door to prevent leaks.

Professional installation is recommended for the best results, especially for frameless models that require precise alignment.

Customization and Additional Features

Customizing your shower door can turn a simple bathroom into a personal retreat.

  • Frosted or Tinted Glass: Offers privacy while still letting in light.
  • Decorative Patterns: Add a unique touch with custom-etched designs or patterns.
  • Functional Features: Consider doors with built-in towel bars or ergonomic handles for added convenience.


Converting your bathtub into a shower with the right shower doors for bathtubs can dramatically change the feel of your bathroom. Not only does it add a touch of luxury, but it also optimizes the space for better functionality. Remember, the key to a successful transformation is in the details—from choosing the right door to ensuring a professional installation.
