If you're planning to remodel or upgrade a bathroom, style is just as important as efficiency! Installing sliding doors on tubs and shower combos is one of the most common choices. Sliding doors provide a polished, contemporary look that also maximizes floor space. But if you have a fiberglass tub /shower combination, you're probably asking: Can you even put sliding doors on a fiberglass tub/shower combination?
Here at Ace Decor we're bathroom furniture specialists that appreciate the value of making educated decisions in regards to your bathroom refurbishment. In this guide, we'll walk you through every thing you need to get to know to install sliding doors on fiberglass tubs, including installation challenges, advantages, and what to think about when planning a setup. Let's dive in.
What is a Fiberglass Tub and Shower Combo?

Before we touch on sliding doors, let's start by understanding what a fiberglass tub/shower combo consists of. A fiberglass tub/shower combination is a fixture that has a bathtub and shower combination built into the unit. Fiberglass is a popular material for these combos because it is tough, light-weight and easy to install. Fiberglass is a common material used for tub and shower construction because it's inexpensive and forms a smooth, easy-to-clean surface.
But when the job calls for installing doors, fiberglass tubs may present particular challenges. Fiberglass is flexible to a certain degree and may not be as firm as alternatives such as acrylic or ceramic. This adaptability can make it difficult to install sliding doors that need a strong frame to operate.
Can I install a sliding door on a fiberglass tub and shower combo?

Yes, you can put sliding doors on a fiberglass tub/shower combo, but it takes time, patience and the proper hardware. Overall, you can add sliding doors to your fiberglass tub, you just have to consider the following:
- Door Weight: Per square foot sliding glass doors are heavy. Fiberglass is more flexible than vinyl and some other materials, and if the door's weight doesn't have enough support, frames can become warped. The track must be installed correctly to distribute the weight.
- Wall support / stability: For the sliding doors to work it is necessary to have solid walls, the wall must be strong to fit the mounting hardware. If the walls around your fiberglass tub/shower combo are not sufficiently secure you might need to reinforce them to avoid any moving or warping in the future.
- Shower Space: Sliding doors are designed to be installed in sliding shower doors for an oversized walk-in shower, when your bathroom has enough space. If you have a small bathroom, a sliding door configuration for your fiberglass tub-and-shower combination might not be the optimum choice either. Sliding doors need clearance on each side to open and close, and if your space allows for that, go for it!
- The right Track System: If you have a fiberglass tub, choosing the right track system is critical. You'll want to look for a lightweight, fiberglass-friendly model, and stay away from any heavy-duty tracks that are designed to handle other materials (like ceramic or acrylic). Instead, look for a track system made for fiberglass tubs — or one that is adjustable.
Advantages Of Sliding Doors On Fiberglass Tub/Shower Units
The installation of sliding doors on a fiberglass tub/shower combination may take a little bit of coaxing, but your efforts are well-rewarded. Stylish and modern options here are a few reasons why you may want to opt for sliding doors for your fiberglass tub:
- Space-saver: The sliding door is perfect for a bathroom in a small space. While hinged doors open in, sliding doors run parallel to your shower, tucking in behind the next panel to get the best use out of the space and helping your bathroom feel larger and more open.
- Contemporary Sliding Doors: On-trend style. Whether you decide on a no-thrills frame or something a little more ornate, they can add a lot to the overall look of your bathroom.
- Ease of Use: The convenience of the sliding doors and easy operation make accessibility a breeze. Because they glide along a track, they are very easy to open and close and are an ideal option for users of all strengths.
- Water Retention: Sliding doors, when installed correctly, help keep water contained within the tub or shower and prevents the risk of leaks or water damage to your bathroom.
What to Consider for Installing Sliders on Fiberglass Tub/Shower Combinations

Even though it's do-able to install sliding doors, there are a few important points to consider if you want to see the doors running for time to come without any problems. The factors to consider include types of materials, how to prepare the area for installation, and how to keep the doors in good condition over time.
1. Selecting the Best Sliding Door System
We have a selection of sliding doors to fit your application at Ace Decor! When choosing sliding door system for your bathtub made of fiberglass, make sure to pick a model suitable for fiberglass. A few key things to look for:
- Adjustable Tracks: Adjustable tracks help accommodate slight variations in wall width and make it easier to install the doors securely on fiberglass tubs.
- Reinforced Door Panels: Choose doors with reinforced glass panels or very thick, heavy materials that can bear the load without placing too much pressure on the fiberglass.
- Seals and Gaskets: Look for good seals and no leaks around gaskets, especially in a fiberglass tub/shower combo, which might have to be replaced if water has escaped to the subfloor.
2. Prepare the Installation Area
In preparation for the sliding doors, the space surrounding the fiberglass tub must be prepared. Here's what to do next:
- Verify the Stability of Your Walls: Another consideration when choosing a fiberglass tub is that the walls of the space around your tub need to be fairly stable. Walls might need extra brackets or anchors to hold the weight of the sliding door system.
- Clean and Level Surface: Before installing, the surface of the fiberglass tub and walls around it will need to be clean and level. A smooth surface will enable the sliding door system to adhere properly and operate correctly.
- Measure the Space: Measure the opening and the space around the tub where the track will be installed. This guarantees the door system will fit right and operate perfectly.
3. Installation Tips
- Have the Right Tools: You will need a drill, screwdriver, level, and tape measure. Carefully follow manufacturer's instructions to avoid any installation problems.
- Think About Professional Help: If you're not comfortable doing it on your own, you can always consider getting professional help for the installation of the sliding doors. A professional will make sure that the doors are set properly and airtight to avoid problems later on.
