A walk-in shower with a single glass panel is the most minimal enclosure there is. No door to open, no hinges, no handle, nothing to swing into the room. Just one sheet of glass that blocks the spray, and an open entry beside it. It looks effortless, it is the easiest enclosure to clean, and it is one of the most popular choices in modern bathroom remodels.
It also only works in the right layout. Put a splash panel on a shower that is too short, or with the shower head pointing at the opening, and water ends up on the bathroom floor. This guide explains when a doorless walk-in works, how big it needs to be, and how to plan the panel so it keeps the water where it belongs.
The short answer
A splash panel, sometimes called a fixed panel or screen, is a single piece of tempered glass fixed to the wall and the floor or curb. It runs part of the way across the shower and leaves the rest open as the entry. There is nothing to open and nothing that moves.
The panel is held in one of two ways: with clamps at the wall and the floor, or set in a low-profile U-channel along the bottom. A support bar from the top of the glass to the wall or ceiling adds rigidity on taller or wider panels. Our guide to channel versus clamps compares the two fixings.
Water needs room to land and drain before it reaches the opening. A long, narrow shower, where you walk in at one end and the shower head is at the other, is the ideal shape. The longer the run from the spray to the entry, the less water reaches the floor outside.
The spray should hit the back or side wall, or the glass panel itself, not aim out of the entry. A rain head mounted in the ceiling over the far end of the shower works very well with a splash panel. A handheld shower is fine as long as you use it sensibly.
A curbless or low-curb walk-in relies on the floor falling toward the drain, and the drain sitting well inside the shower. A linear drain along the back wall is a popular choice. This is set by your contractor before tile, which is another reason to plan the glass early. See when to order glass during a remodel.
The glass should run far enough to block where the water actually goes. We plan the panel width around the shower head position, the opening you want and the size of the shower, and we will tell you honestly at the measure if a splash panel is likely to let water out.

Which shower door fits your bathroom?
Splash panels are usually 3/8 inch tempered glass; 1/2 inch adds rigidity on large panels. Clear and low-iron glass keep the open look; a frosted panel adds privacy while still letting light through. Our glass guide has a side-by-side comparison.
Most panels run to around the same height as a standard shower door. Taller glass blocks more spray and looks more architectural.
Wider panels may need a support bar to the wall or ceiling. It can be finished to match your hardware, and in matte black or satin brass it becomes a deliberate design line.
With so little hardware, the finish is subtle, but it still shows at the clamps and the support bar. We offer polished chrome, polished nickel, satin brass, oil rubbed bronze, matte black and brushed nickel.
| Splash panel | Hinged door or slider | |
|---|---|---|
| Look | Most open and minimal | Fully enclosed |
| Water control | Depends on layout | Strong in any layout |
| Cleaning | Easiest: one panel | More glass and hardware |
| Warmth | Cooler, open to the room | Holds warmth better |
| Accessibility | Excellent, nothing to open | Good with a wide door |
| Needs | Long shower, sloped floor, head aimed away | Room for the door or a slider |
A curbless walk-in with a splash panel is one of the easiest showers to use as needs change. There is no door to manage, nothing to step over, and room for a shower seat or grab bars. If you are planning to stay in your home for many years, it is worth considering now, while the bathroom is being remodelled. Ask your contractor about grab bar blocking in the walls at the same time.
A fixed panel on a tub is the walk-in idea applied to a bathtub: glass at the shower end, open at the other. It is lighter and more open than bypass doors, and very easy to clean. It works best when the shower head is at the panel end.
Not if the layout is right: a long enough shower, the spray pointed away from the opening, a sloped floor and a panel that covers the spray zone.
Wide enough to walk in comfortably, without being so wide that spray reaches it. We plan it around your shower at the measure.
Yes. A fixed panel on a tub keeps water in at the shower end while leaving the rest of the tub open.
Usually, because it is one panel with less hardware. Our cost guide explains what moves the price.
As far as practical. A long shower with the head at the far end keeps the most water in.
Sometimes a hinged door can be added to an existing panel, depending on the hardware and the opening. Ask us at the measure.
