What Size Wet Room Screen Do I Need?

I stood in a half-finished bathroom the other week, shoes politely muddy, staring at a lovely open shower area and thinking: to be honest, this is where good intentions go to get splashed.

A wet room can feel calm and hotel-like, but only if the glass is doing its job. Too small and you end up with a daily mop routine. Too big and the room can feel oddly boxed in.

If you've ever asked "What size shower screen do I need?" you're in good company. At Bathroom Outlet, we hear this question all the time - from homeowners planning their first renovation to tradespeople who simply want the numbers to be right.

Start with the tape measure (then measure again)

A proper wet room screen measurement guide begins with two things: width and height.

For screen width, measure from the finished wall surface to where you want the glass to end. Finished means tiles are on - or at least that you've accounted for tile thickness and adhesive. People often forget that bit.

For screen height, measure from the finished floor to your preferred top line. In most wet room designs, screens sit somewhere around 1950 to 2000mm, but it varies by range and style.

It's also worth checking that the wall is reasonably straight. If it's leaning even slightly, it can affect the fit and the seals.

How much splash can you live with?

This is really the heart of choosing the right walk-in shower screen size. The more open the space feels, the more water tries to escape.

If you love a big rainfall shower head, you'll probably want more glass than someone using a small handset pointed politely downward.

Think about where the shower head sits. If it's on the wall beside the opening, water will wander. If it's positioned deeper inside the showering area, life becomes much easier. A shower splash guard only works if the spray isn't aimed directly at the gap.

Standard sizes - and why they’re only a starting point

Most wet room glass panels come in familiar widths - often 700, 800, 900, 1000 or 1200mm, with a few sizes in between. Heights usually cluster around 1950mm or 2000mm.

Still, wet room screen sizes in Ireland can vary by brand, glass thickness and whether the panel is framed or minimalist. So it's best not to assume every range is identical.

Also remember ceiling clearance. If you have a low ceiling, bulkhead or downlights nearby, it's wise to leave a little breathing space at the top.

Fixed panel or add a return?

A fixed shower screen panel is the clean, simple option. Great sightlines, minimal hardware and easy to wipe down.

If you need more splash protection, a return panel shower screen can make a big difference. That short side panel blocks spray without making the space feel enclosed, and it helps guide you naturally into the shower area.

For wet room screen installation, many setups use a support bar. Check where it will land - it needs a solid fixing point and can sometimes clash with tall tiles, windows or awkward ceiling angles.

Accessibility and when to call in a pro

If accessibility matters, aim for a wider entry and keep the opening clear. A larger panel can still work well as long as the approach is roomy and the layout suits how you move through the space.

And sometimes it's worth getting advice. If your floor falls are tricky, waterproofing is new territory, or the wall isn’t perfectly plumb, a professional installer can save you a lot of muttering later.
