Thinking about upgrading your tub/shower combo with a sleek half-glass shower door? These partial glass panels (sometimes just called half shower doors) are a popular way to give your bathroom a modern, open feel.
They look great and are practical – but before you install one, it’s important to understand the basics. With a little planning, you can enjoy this stylish update without ending up with water all over your floor.
What's Inside
What Is a Half-Glass Shower Door for a Bathtub?

Rather than covering the whole tub, a half-glass shower door uses a single panel to block off just one side—usually where the water comes out. The other side stays open, which is handy for getting in and out. It’s sometimes called a bath screen or a partial tub enclosure.
Most half-glass panels are about five feet high, which is similar to a shower curtain, and they only run halfway down the tub. They do a good job of catching the spray while still giving you open space.
The result? A clean, airy look you’ll often see in modern hotels or spas! It’s a middle ground between a full enclosure and a shower curtain.
Benefits of a Half-Shower Door on a Tub
What exactly is so appealing about a half-glass tub door that makes so many homeowners opt for this style?
Here are a few perks:
- Modern, Open Style: Clear glass makes the bathroom feel bigger and shows off your tile and fixtures. It’s an instant style upgrade from a billowy shower curtain.
- Easy to Clean: With less glass to cover, cleaning is quicker than with full enclosures. And you can say goodbye to washing or replacing mildewy shower curtains.
- Light and Airy: The open top and end let light in and steam out. You won’t feel closed in, and it helps keep the bathroom ventilated.
The main trade-off with a half shower door is managing water splashes. But with smart placement and installation, you can keep splashing to a minimum — more on that below.
Sizing and Positioning the Glass Panel
Half-glass shower doors aren’t one-size-fits-all, so careful planning is needed for your space:
- Width of Panel: On a standard 60-inch tub, a panel around 30 inches wide is common.
- Height of Panel: Most panels are about 55–60 inches tall from the top of the tub, usually enough to catch the shower spray.
- Position at Showerhead End: The glass should be mounted at the same end as the showerhead. This way, the water is mostly confined behind the glass instead of splashing out the open side.
- Leave Adequate Opening: You want the remaining gap to be wide enough to get in and out comfortably (around 24–30 inches is typical). Give yourself enough room to move, but not so much that water easily escapes.
- Fixed Panel or Swinging Door: A fixed panel is simplest (no moving parts), while a hinged half-door can swing open for easier entry and cleaning (just ensure you have space for it to swing and proper seals to prevent leaks).
Installation Tips and Considerations
This isn’t a project that leaves any room for error—it’s important for the half-glass shower installation process to be as precise as possible.
Here are some tips to help the process go as smoothly as possible:
- DIY or Hire a Pro: If you’ve got the tools and feel confident, go ahead and follow the step-by-step instructions that come with the shower panel. If not, hiring a pro might save time and help you avoid any crooked installs or loose seals. If not, hiring a professional can save time and ensure the glass is mounted correctly.
- Secure Mounting and Alignment: The glass panel usually mounts to the wall with hinges or brackets (and may sit in a track or clips on the tub edge). Use proper anchors (or drill into a stud) so it’s firmly supported. Make sure the panel is perfectly vertical (plumb) and sits flush on the tub before you tighten everything. Even a slight tilt outward can allow water to leak out.
- Seal the Edges: Apply silicone caulk along the bottom edge where the glass meets the tub as well as on the wall edge or any metal track, as the manufacturer instructs. Most panels also come with clear plastic strips that stick to the bottom edge (and sometimes the side) to help keep water where it belongs. Don’t skip these – they are key to a watertight setup.
- Plan the Door Swing: Do you have a hinged half-door? Then make sure it can open fully without hitting anything (usually best if it swings outward). Also, check that it snugly meets the tub and wall with its seals when closed.
Tips to Minimize Water Splash
With part of the space being “open,” you might be worried about water escaping out onto the floor.
Here are a few tricks to keep the water where it belongs:
- Aim the Showerhead: Adjust your showerhead to angle inward toward the wall or downward. Before turning on the water each time, try to remember to check it and make sure it isn’t pointing toward the open space. A handheld showerhead that you can aim downward is even easier to control.
- Add a Splash Guard: Some half-door designs include a small pivoting wing panel for extra coverage. If yours doesn’t, you might try sticking on a clear deflector strip at the edge of the glass to help catch stray sprays.
- Keep a Bath Mat Outside: If you’re not already in this practice, place a bath mat or absorbent rug right outside the tub. That way, any little drips when you step out (or if you open a wet door) will be caught. It’s normal for a few droplets to escape – but a mat ensures you at least won’t slip, and it keeps your floor dry.
Don’t skip a quick test shower after installation! If you notice any water sneaking out, dry the area and add a bit more caulk or adjust a seal strip as needed. Tiny adjustments before you resume your regular shower schedule make a big difference in containing splashes.
Making the Most of Your Half-Door
Opt for tempered safety glass and quality hardware when choosing a half-glass door. Frameless clear glass offers the most open feel, but frosted or textured glass can add privacy or a decorative flair.
Pick hinges and fixture finishes that complement your bathroom’s style for a cohesive look, too.
Be sure to account for how you’ll use it on a day-to-day basis.
For example, if kids will use this tub, expect a bit more splashing (some parents hang a curtain on the open side for children’s bath time). For a primary or guest bath used mainly by adults, splashes should be minimal and well worth the sleek look.
Either way, plan to give the glass a quick wipe now and then so it stays sparkling — which is still much easier than dealing with a dingy shower curtain.
